largely by the degree of control of, and practices exercised by, existing 

 agencies, regulations, and guidelines. The help of coastal planners may be 

 needed to establish the means and motivation to make environmental protective 

 measures on these lands more effective. 



RESEARCH NEEDS 



A lack of resource inventories is a major data gap for coastal Maine. The 

 size, abundance, and distribution of agricultural and developed land must be 

 better known. To do that the criteria for distinguishing two of the land 

 types (farmland and abandoned) must be better established and corresponding 

 surveys must be conducted periodically to determine their statuses and 

 changes . 



The current uses of biocides, their chemical composition, method of dispersal, 

 and their potential and actual ecological effects in coastal Maine need to be 

 better known, especially as they relate to surface and ground water supplies. 

 A systematic and periodic survey that would provide data on actual and 

 projected levels of contamination throughout each region is needed.
