## 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  
Following the inventory, we stablished six environmental land units that are represented in Figure 6 and described as follows:  
1. Environmental Land Unit 1 (ELU1): The formation of marginal grassland. This unit comprises perennial species (mainly nitrophilous and sometimes woody perennials)  
Figure 5: Distribution of _Vella lucentina_ in the study area, indicating the position of the endemic plants in the cadastral subplots (pointed in blue). located on the margins of cultivation plots and composed of annual species mainly of the genera Graminaceae, Malvacaeae, and Chepodiaceae. 2. Environmental Land Unit 2 (ELU2): The formation of Aleppo pine forest with sparse woodland (forest). This unit is characterized by the presence of shrubby species that comprise the understory, with tree species also present in areas of use for pastures or scrub, with medium coverage. The Aleppo pine (_Pinus halepensis_) is the dominant tree species, comprising 65% of the total cover. Among the most frequent species is the _Vella lucentina_. 3. Environmental Land Unit 3 (ELU3): The formation of Aleppo pine forest with sparse woodland (forest). Formed mainly by shrubby species and, to a lesser extent, by tree species, located in pasture areas with medium vegetation coverage. The main tree species are the Aleppo pines (_Pinus halepensis_) with uniform distribution, close to 75% of the total tree cover. Among the most frequent species is the _Vella lucentina_. 4. Environmental Land Unit 4 (ELU4): The formation of dispersed Aleppo pine forest with sparse woodland (forest). Formed mainly by shrubby species, located in the areas of pastures and scrub. The main tree species are the Aleppo pines (Pinus halepensis) with irregular discontinuous distribution. Among the most frequent species is the _Vella lucentina_. 5. Environmental Land Unit 5 (ELU5): The formation of grassland-scrubland, constituting of shrubby and herbaceous species, is observed in areas with land cover of scrub-grassland and areas of agricultural use (almond trees and some vineyards) that have been abandoned, with low coverage. 6. Environmental Land Unit 6 (ELU6): The formation of pasture-scrubland, which comprises shrubby and herbaceous species, occurs in areas with a medium level of vegetation coverage.

The final present phytobiological value (FPPV) of the different environmental land units was obtained according to the methodology described in Section 3.2.2. and the results are presented in Figure 7.  
It can be observed that only ELU3 has a maximum value, while ELU2, ELU4, and ELU6 have notable ones. However, the least valued were found in ELU5, with a medium value, and ELU1, with a low value. Determination of Land Capacity for Proposed Activities in Each Environmental Land Unit of the Study Area  
Firstly, we consider the following nine proposed activities to develop in the study area, after the exclusion of industries and hunting due to legal restrictions on establishing such activities in proximity to a residential area, such as Alenda Golf:  
1. Strict maintenance of current activities (SM): This option entails the maintenance of the current situation and its evolution without human intervention or minimal intervention, with a focus on strictly cultural and scientific use. The areas in question would be worthy of establishing more restrictive protection figures, such as a declaration of a micro-reserve or inclusion within the municipal natural park. 2. Ecosystem regeneration (ER): treatments capable of redirecting the area to apply it to its original situation or other more valuable balances. 3. Scientific-cultural activities (SAs): use of the environment for cultural experiences or scientific research for the dissemination of knowledge. 4.
