Land use change and their impacts on the landscape connectivity in the Selva El Ocote-Finca El Corinto corridor. Rev. Mex. Biodiv. [online]. 2023, vol.94, e945151.  Epub 11-Jun-2024.

We analysed the spatial and temporal patterns of land cover and land use in the Selva El Ocote Biosphere Reserve (REBISO) and their impacts on the functional connectivity of the landscape according to 2 indicator species, the pava cojolita (Penelope purpurascens) and the pajuil (Penelopina nigra). We used 2005 and 2019 land cover maps prepared from high-resolution satellite images. The predominant matrix in both years was shrubby secondary vegetation (37.7%), in which mature (3.6%), and secondary (35.8%) forests were immersed, in addition to other non-forest cover (22.9%). During this period, 753 ha (0.7%) of mature and secondary forests were deforested, and 226 ha (0.2%) were regenerated. The fragmentation of the area increased between 2005 and 2019, but the contagion (CONTAG) was 61.6%, showing intermediate structural connectivity of forest vegetation. Functional connectivity for both species was concentrated in the core zone I of the REBISO and for the pava cojolita, also towards the south of this area. We also highlighted the critical areas for maintaining and improving the functional connectivity of these species within this protected area.
