Nature Conservation 48: 31—56. https://doi.org/10.3897/natureconservation.48.79936 Abstract Citizen Science (CS), the voluntary participation of lay people in scientific work, is well-established in the fields of nature conservation and biodiversity monitoring due to its potential to create large environ- mental datasets. This study aims to understand the familiarity, perceptions and attitudes towards CS of the key environmental actors in Greece. The target group consisted of employees and/or representatives of Environmental Non-Governmental Organisations (ENGOs), scientists and civil servants related to nature conservation. Quantitative data were collected using an electronic questionnaire, 178 fully completed questionnaires and subsequently eight semi-structured interviews with experts were conducted. Descrip- tive statistics were used to measure the familiarity and attitude of the actors, as well as the obstacles to the development of CS in Greece. We used Cronbach’s test to measure the reliability of the used Likert scale and Kruskal-Wallis non-parametric test to identify significant differences amongst the three groups of ac- tors. Qualitative data were analysed following a Thematic Analysis methodology. The results show that ca. 40% of the key actors are familiar with the terms and CS practice while over 65% with the concept. The general attitude of the actors towards CS is positive although concerns about data quality collected were highlighted. “Lack of cooperation culture”, “Ignorance of the existence of the phenomenon” and “Lack of know-how” emerged as the most important obstacles to CS development in Greece. Although CS is present in Greece, it is not visible enough. The main reasons are that relevant projects employ different terms, are under-represented in the formal literature and include limited, if at all, project dissemination. There are significant differences regarding familiarity and the attitude towards CS between actors, but also similarities concerning the main obstacles. The study sets a baseline which can be employed to improve and further expand Environmental Citizen Science (ECS) in Greece. Copyright C. Galanos & I. N.Vogiatzakis.

Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31—56 (2022) Keywords Academia, government, mixed methods, nature conservation, NGOs, survey Introduction Public participation and knowledge production can take many forms (Shanley et al. 2019) with Citizen Science being, perhaps, the most widely used and better under- stood by the public. In fact, the practice of Citizen Science (CS) is not new, since for most of the recorded history, it was the public that advanced science - often by just observing nature (Miller-Rushing et al. 2012). The history of amateurs conducting research and collecting environmental data from the field is very old and expands from Norway to France, Japan to China and US (Miller-Rushing et al. 2012). Undoubtedly, the current concept of CS, that is, the involvement of the public in scientific work, has evolved primarily over the past two decades (Cohn 2008). This is obvious by a num- ber of indicators, such as the steep rise in the biodiversity-orientated CS projects over the last 30 years (Theobald et al. 2015), the expansion of scientific reports and peer- reviewed articles resulting from CS project data (Bonney et al. 2014; Vann-Sander et al. 2016) and the establishment of professional CS organisations around the world, es- pecially in the US, Europe and Australia (Ellwood et al. 2017). Moreover, CS projects cover a breadth of scientific disciplines from biology and biodiversity data collection, to the interpretation of astronomic images, archaeology and chemistry (Dickinson et al. 2010; Conrad and Hilchey 2011; Franzoni and Sauermann 2014; Kullenberg and Kasperowski 2016). There are certain factors which enabled the proliferation of CS during the last dec- ades. One of the most important drivers is the technological breakthrough and all the new possibilities for data gathering and dissemination of information from the public (Silvertown 2009; Dickinson et al. 2012). These technological innovations include the internet, smartphones, Global Positioning Systems (GPS), web geographic informa- tion system applications, the increased availability of domestic internet connections and the reduction of costs for computer storage. On one hand, the increasing realisa- tion amongst professional scientists that the public can provide free labour, skills, com- puting power and even funding and, on the other hand, the growing demands from large research funders for public engagement led to new and innovative CS projects (Cohn 2008; Silvertown 2009). In addition to technological factors, social factors also played an important role in the expansion of CS. Two of those prevail. The first one is the growth in the population of well-educated individuals who possess the skills to perform scientific tasks, but do not use their knowledge in their daily life. The second factor is the increase in leisure activities as a result of the reduction in working hours in advanced economies (Haklay 2013). CS is best established in biological sciences and, in particular, in biodiversity and natural resources monitoring (Follett and Strezov 2015; Kullenberg and Kasperowski 2016; Schade and Tsinaraki 2016; Pettibone et al. 2017; Pocock et al. 2017). Nowa- days, probably the principal reason for this dominance of biology-related CS projects Environmental citizen science in Greece 33 is the realisation of scientists that CS is perhaps the only practical way to gather data at large geographical scales, time periods and private lands. Such large datasets are neces- sary for biologists to understand the processes and to address ecological questions, such as climate change, patterns of migration and spread of diseases (Dickinson et al. 2010). In recent years, a number of studies reviewed the field of Environmental Citizen Science (ECS), to determine the effective use of the data collected in biodiversity re- search (Theobald et al. 2015; Chandler et al. 2017), to assess the diversity and evolu- tion of the ECS field (Pocock et al. 2017), to understand the diversity of CS in specific countries (Pettibone et al. 2017) or to assess projects that can be of relevance to envi- ronmental European policy (Bio Innovation Service 2018). Studies about CS as a social phenomenon have dealt mainly with how the citizens react, participate and understand it, with emphasis mainly on motivations (Alender 2016; Domroese and Johnson 2017) or barriers to participation (Martin et al. 2016). For example, information from interviews with representatives of biodiversity-record- ing organisations shed light on motivations of citizens to participate in biodiversity- monitoring CS projects and demonstrated that people from socio-economically de- prived areas are under-represented in those schemes (Hobbs and White 2012). Dur- ing recent years, emphasis is given in motivation to participate in online CS projects (Raddick et al. 2010; Nov et al. 2014), the use of smartphones (Land-Zandstra et al. 2016b) and gamification strategies (Greenhill et al. 2016) to enhance citizens’ partici- pation. What remains limited though, are insights about the main initiators/groups of actors of ECS projects (ENGOs, scientists, governmental organisations) and interac- tion between those engaged (Rotman et al. 2012; Weng 2015). Motivation and data collection are perceived differently by citizens and groups of actors (Jiang et al. 2018) with scientists more concerned about the quality of data and peers’ approval (Riesch and Potter 2014; Burgess et al. 2017) rather than the opinion and needs of citizens when engaging in ECS projects. In Greece, most of the examples of ECS projects are usually initiated by ENGOs, such as the Hellenic Ornithological Society (HOS) or the Hellenic Marine Environ- ment Protection Association (HELMEPA). The country may benefit from such pro- jects given that: a) its biodiversity is considered to be one of the richest in endemism in Europe and in the Mediterranean (Georghiou and Delipetrou 2010) and that: b) due to the recent economic crisis, the adoption of an austerity programme (Matsaganis 2014) has weakened environmental administration and surveillance mechanisms, add- ing extra threats to Greek biodiversity (Lekakis and Kousis 2013). Therefore, CS has a distinct role to play as a mechanism to support nature conservation as well as public engagement with nature and science (Devictor et al. 2010). Nevertheless, the specific cultural and socio-economic characteristics of each country play a decisive role in the success or failure of such projects. These might be expressed through past environmen- tal history, collaborative culture, legal frameworks and organisational context. Recom- mendations exist in literature, but most studies come from relatively rich, industrialised countries and little knowledge exists for the specific challenges of initiating monitoring schemes in different contexts (Danielsen et al. 2003) with few perhaps exceptions (e.g. Loos et al. 2015). Although users’ profiles are important factors in shaping citizen 34 C. Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31-56 (2022) science (Amarasinghe et al. 2021; Aristeidou et al. 2021), this study focuses on three specific sectors (Public bodies, Research/Academic Community, ENGOs) since they are the ones which deal with conservation on a day-to-day basis, can formulate policies and/or influence decision-making. The aim of the study is to understand the perceptions and attitudes of the main actors engaged in environmental management and nature conservation in Greece to- wards CS. ‘Three target groups, environmental data collection actors, from ENGOs, research centres and/or higher educational institutions (Universities/Technological In- stitutes) and government sectors were selected. ‘To achieve this aim, five key questions were addressed: ¢ to what extent are the three groups of actors familiar with the term, the con- cept and practice of CS? e what is the attitude of the actors towards CS? e which are the main obstacles to the development of CS in Greece? e which are the main reasons for the reduced visibility of the term in Greece? e are there significant differences amongst the actors in relation to the above- mentioned questions? Materials and methods The research approach was based on mixed methods and, more specifically, an explana- tory sequential, where a quantitative step was first conducted, followed by a qualitative part to elucidate the most interesting findings. In the first quantitative phase of the study, survey data were collected from a number of respondents using an electronic questionnaire (Appendix 1 Questionnaire). The sample was drawn from a population of professionals within the field of environmental monitoring and nature conservation: employees and members of ENGOs, environmental scientists working on research centres and higher educational institutions (Universities/Technological institutes) and civil servants and government authorities all engaged in the topic of environmental conservation. This represents a convenient sampling technique; thus, our results can- not be considered representative and cannot be generalised. However, for exploratory studies like this one, convenience samples are considered sufficient (Sue and Ritter 2007, 25). Our sample comprised 644 emails, both personal and organisational. Contact de- tails including e-mail addresses used in this study were publicly available on the inter- net through the organisations’ official website (for researchers and civil servants) and the database for ENGOS maintained and regularly updated by the National Centre for Social Research in Greece (1 EKKE/IAAK. (n.d.). Retrieved 17 February 2019, from http://ekke.gr/estia/eng pages/eng index.htm) The questionnaire included questions on demographics, familiarity with the term, the concept and the practice of CS, using a Likert-scale with an aim to capture the perceptions and attitudes of the actors towards CS. The statements expanded from the Environmental citizen science in Greece 35 most cited positive effects of the practice (Devictor et al. 2010; Dickinson et al. 2010; Roy et al. 2012; Science Communication Unit 2013; Pocock et al. 2014) up to the most common reasons for reluctance to accept it, for example, data quality (Rotman et al. 2012, 2014; Hyder et al. 2015; Minkman et al. 2015; Geoghegan et al. 2016; Burgess et al. 2017; Haklay et al. 2017), as well as a question about the main obstacles to the development of CS in Greece. All the questions of the survey were compulsory, except for a question about the name of the organisation and the last field where the respondents were asked to provide their e-mails in case they were also willing to pro- vide an interview. For the compulsory questions, the option “I do not know / | do not answer or “| do not answer” was also given to the respondents. We piloted the questionnaire by distributing to six researchers, one representative of an ENGO and a public servant who provided initial feedback. Their answers were not included in the final dataset, while those respondents did not answer the final ver- sion of the questionnaire. The survey was initiated on the 23 April 2018 and it was closed on the 17 May 2018. The software used to publish the survey and collect the responses was LimeSurvey Version 2.06, an open-source online survey tool installed on the servers of CIHEAM-MAICh. The questionnaire was designed to take approxi- mately ten minutes. Those quantitative data were used to answer four out of the five research questions. The quantitative data from the survey were imported and analysed in Rstudio Version 1.1.453 (R version 3.3.3). Ggplot2, reshape2 and sjp.likert functions in R were used to produce the graphs. Descriptive statistics, such as summaries, percentages, means and standard deviations, were also calculated. After the initial data analysis, the fourth research question was formulated. The qualitative phase was conducted to help answer the fourth research question and ex- plain the most important results of the third research question. For the second phase of the study, semi-structured interviews of eight experts were conducted. For the purposes of the qualitative part of the research, a smaller sample of 30 possible interviewees was created after an initial analysis of the questionnaire data. The possible interviewees were selected on the basis of two criteria: they were familiar with the term and/or the practice of CS and they had responded positively in the final question of the survey concerning their availability for a telephone interview. First, the participants that met the above-mentioned criteria were identified and then ten for each group of actors were randomly selected. Even if the aim of the semi-structured in- terviews was to interview representatives from all three groups of actors, unfortunately, we did not receive a positive reply from any representative of the public sector. Thus we interviewed five employees/representatives from ENGOs and three scientists from the research/academic sector. The interviews were undertaken from 26 June to 17 July 2018. The interview guide was composed of one introductory question, two main topics of discussion and a closing part where the interviewees were asked to write anything additional which they considered important. The introductory question was how the interviewee’s work is related to environmental monitoring and nature conservation. One main topic of discussion was about possible reasons for the non-visibility of CS in Greece. Regarding 36 C. Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31-56 (2022) the other topic, the interviewees were asked to provide their opinion about the first two obstacles to the development of CS in Greece as depicted from the survey. In particular, the methods used to answer the research questions were as follows: for the first research question, we calculated percentages from questions B3, B4 and B5 of the questionnaire (see Appendix 1). For the second research question, we employed questions C1 and C3 of the questionnaire (Appendix 1). Question Cl was a Likert- scale question of eighteen statements. Alpha function was used to calculate Cronbach's a for reliability analysis. To measure the positive or negative attitude of the respondents towards the Likert statements, we assigned numeric values from 1 up to 4 correspond- ing to their level of agreement (Not at all (1), A little (2), Significantly (3), A lot (4)). The negative wording statements were reversed. Then the sum for each statement was divided by the number of the respondents minus the “I! don’t know / | don’t answer” cases. Summing the means of all the 18 statements, we concluded with a score between 18 and 72, depicting the attitude of the respondents towards CS. Then this score was converted to a 0-100 scale to facilitate interpretation. The same process was followed for all the respondents and for each group of actors. From question C3, a table of per- centages was produced. For the third research question, at first, we employed question C2 of the ques- tionnaire and percentages were calculated. During the semi-structured interviews (see Appendix 2 for the list of interviewees), some clarification concerning the first two main obstacles was asked by the experts. The answers were analysed using a Thematic Analysis approach (Attride-Stirling 2001). For the fourth research question, we analysed the transcribed experts’ interviews using a thematic network analysis approach (Attride-Stirling 2001) to RQDA soft- ware. In total, 125 codes were generated. Out of these codes, fourteen categories, or themes, emerged in relation to the reasons for the non-visibility of the practice in Greece and to interpret better the two main obstacles in the development of the CS in Greece according to the actors. Finally, for the fifth research question, comparisons amongst the three groups of actors were performed using the Kruskal-Wallis test, followed by post-hoc pairwise comparisons with the Dunn-Bonferroni approach. Results Out of the 644 e-mails sent, we received 80 delivery failures with 564 emails reaching their target. The survey resulted in 178 fully completed questionnaires, so a return rate of about 30% which is the usual response rate for web-based surveys (Sue and Ritter 2007, 8). From the survey respondents, 16.9% work or represent an ENGO, 30.9% are researchers and 52.2% are working in public bodies. Regarding familiarity of the actors with the term (see question B3), 41.6% of the respondents answered “Yes”, 57.9% answered “No” and 0.6% choose the option “] don't know/I don't answer’. The percentages differed significantly when we exam- ine the results within the three different groups of actors. Researchers were the most Environmental citizen science in Greece 37 familiar group with 72.7% answering that they know the term CS, followed by the representatives from ENGOs with 53.3% and then the public servants with 19.4%. To investigate the familiarity of the actors with the concept, we employed question B4, with 34.8% of the respondents answering “None of the above”, which means that the remaining 65.2% knew at least one of the terms which relate to CS (Fig. 1). The researchers are the ones who were most familiar with the concept of CS since they had the lowest percentage (16.4%) for the option “None of the above” when asked if they know the terms. The second familiar group was the NGOs with 23.3% followed by the public sector with 49.5% (Fig. 2). 50% - _48,3% Figure |.

Responses to question B4 “Do you know any of the following terms” (per group of actors). 38 C. Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31-56 (2022) Finally, regarding the familiarity of the actors with the actual practice of CS, we em- ployed question B5 for which 39.3% of the respondents answered “Yes” to that ques- tion, 57.3% answered “No” and 3.4% chose the option “I don’t know/| don't answer”. In order to answer the second research question of this study, we analysed the re- sponses to question Cl and C3 of the questionnaire. The Likert scale used in C1 had internal reliability: Cronbach's a = 0.79. As a general rule of thumb, reliabilities with Cronbach's a above 0.7 are considered acceptable (Cortina 1993). For the analysis of the Likert scale, numeric values were assigned to the levels of agreement of the respondents and then the mean was calculated for each item and a total sum of all the items. Since the range of the numeric values that we chose to assign was from 1 up to 4, the mean of each item falls within this range. According to this rationale, an item with a mean close to the upper (4) or lower (1) value has a clearer depiction (positive or negative) of the attitude of the actors towards the relevant state- ment. On the other hand, items with a mean value around 2.5 are statements more debatable that divide the respondents. Moreover, the scores of the negative wording statements have been reversed. The sum of the items - for all the respondents and for each group separately - was converted to a 0-100 scale for better interpretation. The scores for all the respondents and for each group of actors are presented in Table 1. Finally, regarding the attitude of the actors towards CS, question C3, 76.4% of the respondents answered “Yes”, 6.7% answered “No” and the remaining 16.9% chose the option “I don’t know/I don’t answer”. Within the groups of actors, the researchers and the employees/representatives of the NGOs had very similar answers. Around 90% believe that a CS programme would be a positive addition to their activities. The majority of the public sector (63.4%) was also positive; 26.9% answered “I don’t know/| don't answer” and 9.7% chose the op- tion “No” (Fig. 3). To answer the third research question of this study, we used the responses to ques- tion C2. The results are presented in Fig. 4 for all the respondents and Fig. 5 for each group of actors. In these two figures, the dark green colour represents the three most important obstacles while light green shows the obstacles above 20%. The three most important obstacles for all the respondents were “Lack of cooperative culture”, “Ig- norance of the existence of the phenomenon” and “Lack of know-how”. The first two obstacles stand out from the rest with 53.9% and 45.5%, respectively. The third ob- stacle was selected in ca. 30% of the responses, while the rest of the obstacles received under 25%. Table 2 presents all the obstacles above 20% - for all the respondents and for each group of actors. From this table, it becomes obvious that five obstacles are very im- portant for all the actors while some obstacles are of importance mainly for the public bodies and the researchers. Following the quantitative analysis, we aimed to further clarify the first two obsta- cles. Therefore, during the interviews, we asked the experts what they believe the rea- sons were for those obstacles. Regarding the first obstacle “lack of cooperation culture”, one important reason that was mentioned by the majority of the interviewees was the problematic operation of the State. This statement refers to a range of activities, such Environmental citizen science in Greece 39 as inconsistent policies and official committees that never function, the absence of participatory processes, no continuity in the priorities of the ministries due to political changes and long delays. Some other reasons were: the absence of volunteering men- tality in Greece, types of behaviour that make difficult the relationships between the research community and the NGOs, lack of proper information and finally, the lack of a culture of acknowledgment by both the State and the researchers creates problems in possible collaborations with the public and NGOs. Regarding the second obstacle “Ignorance of the existence of the phenomenon’, two main reasons emerged through the interviews. We termed the first one “Lack of external stimulus” to refer to bureaucratic organisations with no motivation for partici- patory research or practices. The second reason was that the actors (ENGOs, research- ers, public bodies) have not communicated the term successfully to the general public, so there is a lack of relevant information. Table |.

Dark green shows the first three obstacles, light green obstacles above 20%. During the semi-structured interviews, the interviewees were asked their opinion about the main reasons for the reduced visibility of the term in Greece. A reason that was reported is that the researchers who participate in CS projects often do not publish due to data quality issues. Another reason is that CS within the organisations, if it ex- ists, is a side-line activity, amongst others. Thus, it is not easy to be promoted because promotion needs extra time and effort and the resources normally are scarce. In ad- dition, most of the CS projects that are initiated with some form of EU funding (e.g. Environmental citizen science in Greece 4] Horizon or LIFE+ programmes), do not continue once the funding is over (usually the end of the project). Therefore, there is insufficient time to develop and disseminate their added value in the society. Finally, the majority of the interviewees mentioned that the term is not so visible in Greece because organisations that run relevant projects do not use the term Citizen Science. The familiarity with the term, the concept and the practice of CS differed signifi- cantly amongst the three groups of actors as demonstrated by the Kruskal-Wallis test (Table 3). Post-hoc pairwise comparisons, using the Dunn-Bonferroni test, revealed that respondents from public bodies are significantly less familiar with CS than re- spondents from ENGOs and the researchers. From the eighteen statements of the Likert scale, the Kruskal-Wallis test depicted eight statements as statistically significant (Table 4). The most contradictory pair of actors is "ENGOS-public bodes" which is statistically significantly different in seven statements from the eighteen of the scale. Then the pair “researchers-public bodies” is significantly different in three statements and lastly, the “ENGOs-researchers” pair differs significantly on two occasions.

After the Dunn-Bonferroni post-hoc pairwise comparisons, only the obstacle about the in- sufficient legal framework revealed a significantly differed pair. This pair was research- ers vs public sector employees, with 3.6% of the former and 25.8% of the latter choos- ing "Insufficient legal framework” as one of the main obstacles to the development of CS in Greece. Discussion This study's aim was to understand the perspectives of the three main groups of envi- ronmental actors in Greece towards CS. Similar studies about the main initiators of ECS projects (ENGOs, researchers, governmental organisations) are limited. To our knowledge, no other comparative studies between the main initiating ac- tors of ECS projects (ENGOS, researchers and relevant public bodies) have been con- ducted in Greece to date. Our initial hypothesis was that the majority of the actors in Greece would not be familiar with the practice. After the completion of the quantita- tive part of the study, it became evident that the reality in the field was rather differ- ent. Therefore, the findings that the three groups of actors have significant differences amongst them (Tables 3, 4 and 5), with researchers being more familiar amongst the three groups, with the most positive group towards CS coming from ENGOs, can be considered as the first of this kind. Regarding the familiarity with CS, we are not aware of another study that quan- titatively depicts the knowledge of the actors concerning the term, the concept or the practice of CS. Nevertheless, at a survey of public familiarity with the CS term and concept, we read “...we found that less than half of respondents were familiar with the term “citizen science,” but over 70% were familiar with the concept by another name. (Lewandowski et al. 2017). This is very similar to our questionnaire results where 41.6% knew the term, 65.2% knew the concept and 39.3% have participated in a project with CS characteristics. 44 C. Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31-56 (2022) We found that, in Greece, the term “Public participation in scientific research” (PPSR) is the most familiar amongst the representatives of the actors and this comes in contradiction with the notion expressed in other studies that PPSR has proven to be difficult to use and that the term “citizen science” is already well-established (Eitzel et al. 2017). Regarding the positive attitude of the actors towards CS, our findings are in agreement with previous studies. For example, Minkman et al. (2017) found that wa- ter practitioners in The Netherlands are willing to embrace CS while Riesch and Potter (2014) found that, for scientists participating in Open Air Laboratories (OPAL), CS projects have been a very positive experience. The term crowdsourcing and crowd science were those for which the actors who took part in the study demonstrated less familiarity (Fig. 1). This is despite the increas- ing use of participatory research during the past 20 years. Although not synonymous, the terms are part of the gradient in participatory research where science meets society. Both CS and crowdsourcing may facilitate the dialogue between researchers and public and increase the influence of citizens on research agenda formulation. However, there have been increased concerns about crowdsourcing taking over citizen science which may result in displacing other forms of participatory research (Eitzel et al. 2017). The concerns about data quality collected by citizens are well reported in litera- ture (Burgess et al. 2017) and our study is no exception. Moreover, Riesch and Potter (2014), in exploring the perceptions of scientists about CS, found that the concern of scientists for any disapproval by their colleagues in case they use citizens’ data might discourage them from doing so. Nevertheless, the actors in Greece believe, similarly to other studies (Danielsen et al. 2005; Bio Innovation Service 2018), that, with ap- propriate training, citizens can collect quality environmental data. Although previous studies suggest that, very often, the main motivation for citizen scientists’ involvement is to contribute to science (Raddick et al. 2013; Alender 2016; Land-Zandstra et al. 2016a), according to the opinion of the actors in our study “citi- zens do not have enough incentives to volunteer/engage in scientific research’. Either the actors are right that the public in Greece have low incentives for engaging in general or the actors are failing to recognise volunteers’ prevalent motivations (Rotman et al. 2012). Previous studies support strongly the opinion of the actors regarding the low levels of volunteering trust and social capital in Greece (Lyberaki and Paraskevopoulos 2002). For example, according to the 2008 European Social Survey, the percentage of Greeks who believe that one needs to be cautious of others and thus not trust them was almost double compared to the European average (Clarke et al. 2015, 11). Many stud- ies have emphasized the crucial importance of trust-based relationships and credibility for a sustainable collaborative environment (Rotman et al. 2012; Stone et al. 2014; Vann-Sander et al. 2016). Such an environment is a must for ECS projects to flourish. Semi-structured interviews revealed two possible causes regarding the first obsta- cle i.e. “Lack of cooperation culture”. The first is the relationships amongst the three groups of actors (issues of trust, recognition, reward) and the second, a luck of culture of volunteering in Greek society. Those are in agreement with previous studies that argue for the low levels of trust, volunteerism and social capital in Greece (Clarke et al. Environmental citizen science in Greece 45 2015, 10-11). If we will consider that the fourth and fifth obstacle, “Low levels of trust from citizens to the institutions” (24.7%) and “Lack of incentives on the part of citi- zens” (23%), respectively, are somehow related with the issue of trust, we understand the multi-faceted influence of this factor. Finally, our findings regarding the basic reasons of the reduced visibility of CS in Greece are in agreement with previous studies. More specifically, the first reason emerging from the semi-structured interviews conducted with the Greek actors was the under-representation of CS in formal literature. This possibility is well docu- mented in the literature and has mainly two causes. The first one is related to the scientists’ concerns about data quality (Burgess et al. 2017) and their perceptions that CS data will not be well received by other scientists (Riesch and Potter 2014). The second one is that some CS projects do not have as their objective peer-reviewed publication, for example, NGO projects that mainly aim to educate or affect policy (Burgess et al. 2017). The other reason for reduced visibility of the term in Greece was the usage of different terms in relevant projects. This finding is also in agree- ment with other studies reporting on a variety of terms used to describe data arising from citizens (Shirk et al. 2012; Kullenberg and Kasperowski 2016; See et al. 2016; Eitzel et al. 2017). The third obstacle about problematic or no promotion of relevant projects, for example, no website, no relevant articles in the press, is mentioned in a report by Roy et al. (2012), but also by other authors who tried to create indexes of CS projects (Chandler et al. 2017; Pettibone et al. 2017; Pocock et al. 2017; Bio In- novation Service 2018). Implications for Future CS Attempts and Further Work A key finding of this study was that a significant percentage of actors in Greece, who are professionally involved in the environmental data collection procedure, are famil- iar with the term, the concept or the practice of CS. This finding can have important implications for future ECS attempts since it makes clear that familiarity with CS is not the main issue amongst the actors. A practical step following this finding could be the organisation of a congress or a forum about ECS in Greece. Such an event would be important in order to build synergies and trust amongst the actors, that is partly, the number one obstacle to the development of CS in Greece according to the actors. Since we know which terms are the most familiar within the groups of actors, a possible implication is that the concept of CS can be communicated more effectively in order to be understood by the audience. For example, if we want to communicate the idea to a governmental institution, it is advisable to mention also the terms “commu- nity - based environmental monitoring” or “public participation in scientific research” since our chances to convey the concept will significantly increase. The same goes for the ENGOs, mainly for the term “public participation in scientific research’. Our findings showed that all the groups of actors (ENGOs, researchers, public bodies) are positive towards CS, although to varying degrees. This information could be important if we would like to follow the advice of Bonney et al. (2009) “A successful 46 C. Galanos & I. N. Vogiatzakis / Nature Conservation 48: 31-56 (2022) CS project requires a development team comprising multiple disciplines. ... Small groups or organisations that do not have internal access to all disciplines can partner with other organisations or adapt national CS projects for use at local or regional scales.” . In Greece, the majority of the organisations are small to medium size, so the idea of partnerships probably is the most viable one. Of course, the issue of trust and the consequent lack of cooperation culture in Greece are the main obstacles to the development of CS in the country. However, a practical result of this study is the specific information arising about each group of actors and which can be used for future efforts. For example, we identified the existence of a legal framework as important factor for the public bodies and compliance to specific data collection protocols important for scientists. Moreo- ver, from the analysis of the Likert scale, we can observe differences amongst the groups of actors in greater detail. In addition to similarities, the study also highlighted significant differences amongst the group of actors who usually initiate ECS projects. These actors are char- acterised by different levels of familiarity with CS and relevant terms, they prioritise differently the obstacles and they are more positive or negative towards different as- pects of CS. Further studies are needed to understand the motivations of scientists and citizens to engage in collaborative projects. For example, Rotman et al. (2012) found that the motivations of participants shift over time and often the scientists are unaware or mistaken about those. Another study showed that the perceptions about CS between experts and citizens can differ and this can lead to conflicts and distrust (Weng 2015) or that the experts and the citizens have different views of formal and informal environmental sensing data (Jiang et al. 2018). These studies can be support- ive especially for building synergies and interdisciplinary ECS working groups. More in-depth research in the direction of assessing the perspectives of the actors towards possible collaborations, needs assessment for building ECS projects, mapping the dif- ferent organisational skills and aligning them with the needs within the framework of synergies could be of much help for the development of the field. Moreover, research on case studies of ECS projects that are collaborations of ENGOs, governmental or- ganisations and research institutes we believe are of high importance. Lessons learned and best practices could be of much support, especially for similar contexts to Greece where organisations are of small size without specialised know-how. Future qualitative research should be conducted regarding civil servants and especially their point of view for the main obstacle to the development of CS in Greece that was “Lack of coopera- tive culture”. Despite our efforts, their point of view is missing in this study. We believe that is of great importance if we want to understand better the relationships amongst the actors. The factors that influence the application of CS are diverse and include the specific socio-economic characteristics of each country and geographical regions, history and culture of volunteerism, NGO activity, social capital etc. (Burgess et al. 2017). This study was an exploratory one for Greece and we are aware of at least one in a similar context in Romania (Loos et al. 2015). Despite the fact that the interviews and the questionnaire were carried out in 2018 and significant progress in CS has been made Environmental citizen science in Greece 47 since then, the results set a baseline for further similar studies in Greece as a means to monitor progress in a fast-expanding field. The daily use of mobile apps, social media and online platforms has increased familiarity of lay persons with similar tools engaged in CS nowadays (Willis et al. 2017; Zotos and Vogiatzakis 2018). This familiarisation became a necessity during the ongoing COVID-19 pandemic and resulted in a fast-paced mass digital transition. The ability of the actors in Greece and elsewhere to take advantage of this transition, so to create CS online projects, is an important parameter that we have not explored in this study. As CS advances, new challenges emerge, such as the participants’ personal data protection in CS projects (Suman and Pierce 2018). In the European Union, the legal context is quite advanced with General Data Protection Regulation (G.D.P.R) being the main legal text since 2016 (European Parliament and the Council of 27, 2016). However, the level of familiarity and compliance of the actors with G.D.PR obliga- tions is still variable and should be the focus of future research. There is a need for more regional studies if we want to better understand the spe- cific challenges to the development of CS - and of citizen engagement in biodiversity and conservation science in general - in modern societies. Conclusions Contrary to our initial hypothesis, we demonstrated that the actors in Greece are fa- miliar with and have a positive view of CS to a great extent (majority of respondents in Academia and ENGOs and ca. 50% of public servants). We found significant differ- ences amongst the groups of actors regarding aspects of CS - such as familiarity with it - but also similarities, for example, concerning the main obstacles to the development of CS. We argue for the importance of comparative studies amongst the actors in terms of building knowledge to support synergies and interdisciplinary working groups. The main reasons for the reduced visibility of the term CS in Greece became obvious and are in agreement with previous research. ‘The specific historical and socio-economic context which characterises a country or a geographically-defined area underpins the adoption and implementation of CS. We argue that more studies in different socio- economical contexts and possible comparisons between them, would be of scientific interest and of practical use to formulate public policies. For example, a study from Romania exploring the challenges to initiate a new CS monitoring scheme (Loos et al. 2015) would be of more relevance with the Greek context rather than studies from the US or UK. In addition and given that “ignorance of the existence of the phenomenon” was ranked the second most important obstacle by the actors for the development of CS, there is a need for raising public awareness of CS itself. Towards that direction, a web portal would support further the development of CS in the country by dissemi- nating results beyond the end of each project and create a web presence for projects which currently lack one. 48 C.
