## 3 Description of the Systematic Impact/Aptitude Land Planning Model
### Diagnosis and Territorial Analysis of the Study Area
#### 4.2.1 Definition of the Environmental Land Units of the Study Area
The occasional collection of aromatic species (AS) and intensive grazing (IG), ensuring that they do not result in the regression and deterioration of the grassland-scrubland, would generate economic and cultural value in the area. In the case of extensive agriculture (EA) and camping or recreation (CR), although these activities would also generate economic and cultural value in the area, they would result in a considerable decrease in the associated phytobiological value, such as the loss of landscaping and uniqueness. * Land capacity of Environmental Land Unit 6 (ELU6): In absolute terms, ELU6 yielded comparable results to ELU3, with the exception of the case of the occasional collection of aromatic species (AS) and intensive grazing (IG). The reduction in land capacity is influenced by a decline in the parameters associated with landscaping, soil protection, and the current state of conservation of the endemic _Vella lucentina_. Summarizing, the land capacity for the 54 proposed activities in the entire study area (nine activities for each of the six defined ELUs) is indifferent for 33% (18), medium for 30% (16), low for 22% (12), very low for 11% (6), and high for 4% (2). These mean that only 34% of the proposed activities can be carried out with no problems to endemism (those with a high or medium values), although it could be extended with great caution to the 33% of those who have a value of indifferent. The two proposed activities that can be introduced in the study area with very few restrictions are scientific-cultural activities (SAs) and the occasional collection of aromatic species (AS), because both activities have medium and indifferent values, respectively. Four additional activities could be introduced with caution in the study area, as they present several indifferent values that could become negative at any time, namely the strict maintenance of current activities (SM) (four indifferent, one high, and one medium), ecosystem regeneration (ER) (four indifferent, one high, and one medium), reforestation (RF) (four indifferent and two medium), and intensive grazing (IG) (three indifferent, two medium, and one low). Finally, three activities are incompatible with endemism in the study area, namely camping or recreation (CR) (five low), extensive agriculture (EA) (four low and one medium), and urbanization (UR) (five very low). Finally, the last step would entail the assignment of land uses by management category to each environmental land unit based on their land capacity. The primary concern that needs to be addressed is to prioritize the preservation of the species and to undertake only actions that do not lead to a decrease in the plant population. Consequently, the evaluation of the extended phytobiological value serves as an instrument that restrains future activities in the assessed area. However, this is a decision that falls within the purview of municipal, local, and regional authorities and the balance between environmental conservation, social,and economic factors. This new model facilitates this task and favors the adoption of good strategies.
