Background:Trees and f.r.sts in drylands help mitigate the challenges through provision of economic products and vital environmental services such as habitat f.r.biodiversity,prevention of erosion and desertification,regulation of water,microclimate,and soil *** condition and changes in dry f.r.sts can be assessed by using ecological indicators able to quantify spatial and temporal changes in *** of the ways to determine the condition of the f.r.st is to study the dominant tree species and its *** study aimed to assess whether the abundance of Prosopis flexuosa saplings is affected by environmental and biological ***:To evaluate the f.r.t variables we used data from remote sensing such as satellite images and Aster Global Digital Model(GDEM).The second set of variables was about exotic and native ungulates and we used feces of these animals and camera traps to take *** found that sapling abundance related positively to sandy substrates and negatively to Wetness *** the other hand,in relation to biological variables,the abundance of saplings was positively affected by density of adult trees and by number of seeds dispersed by equines,but space use by Lama guanicoe had a negative relationship with *** research shows that *** saplings are benefited from sandy substrates and the conditions around adult *** addition to this,we found that exotic ungulates in low densities have neutral(***)or positive(***)effects on sapling ***:Based on these findings,we conclude that regeneration of the population of *** in our study area has no major *** addition,we corroborated that the presence of exotic and domestic ungulates in low densities does not have deleterious consequences f.r.saplings of the dominant tree,***.
