Morus sp. is a versatile resource with diverse benefits; however, its cultivation may entail negative environmental impacts. Environmental legislation imposes constraints to mitigate these effects. The current study presents a three-tier classification approach to assess the severity of constraints imposed by environmental legislation on Morus sp. cultivation. The approach is tested in a case study area located in BG0000254 Besaparski vazvishenita, Bratsigovo Municipality, Bulgaria. Approximately 23.6% of this area is under strict protection, thereby prohibiting cultivation. In about 21.3% of the area, Morus sp. cultivation is feasible but most probably an Appropriate Assessment procedure will be required to ensure nonsignificant negative impact. In the remaining 56.4% of the area, notification/screening is necessary, with the likelihood of not requiring a full Appropriate Assessment procedure. Thus, despite a significant portion being under strict protection, there remains potential for Morus sp. cultivation within the study area, albeit with varying procedural complexities.<br> Th&#1077; proposed constraints classification approach can inform land use planning, facilitating informed decision-making in site selection not only for Morus sp. but for all types of permanent crops.
