Abstract

The Northern Jaguar Reserve is a private property located in the Sonoran mountains, within a complex landscape matrix with a wide legacy of livestock use. This region, identified as priority for conservation, has scarce data on vegetation change trajectories, a key element to assess the impact of natural protected areas. This work presents information about the effect of actions for conservation purposes on the vegetation composition after the establishment of the reserve in 2003. The plant communities were characterized, and land cover supervised classifications were generated with medium- and high-resolution satellite images to carry out a cover vegetation change analysis (2003-2018). General accuracies of the classifications were equal to or greater than 0.75, increasing when using images of higher spatial resolution. Combining different spatial resolutions presents advantages for understanding compositional transitions between different plant communities. The trends indicated an increase in subtropical scrub and a decrease in induced grassland, reflecting transformations towards a greater diversity of species and a reduction in potential threats to biodiversity at the landscape level.
