Background:The ecological indicators are useful tools to determine the effects of human disturbances on woodland ***,ecological indicators not always responded in the same way to disturbances,and the responses can differ among *** arid and semiarid woodlands,the use of deadwood associated with cattle raising can affect biodiversity and Nature’s contributions to ***:Our study aimed to assess changes in taxonomic and functional diversity of two assemblages,plants and mammals,in Prosopis woodlands under different land management types:grazed woodlands and a protected *** plants,changes in structural diversity were also *** trees under different land management types were selected and their deadwood characteristics were *** live traps and camera traps,we obtained data on the presence-absence of mammals per tree to estimate diversity *** plants,we measured the abundance of vegetation by species and by cover type through the Line-Intercept Method to estimated ***,we built generalized linear models to assess the responses of diversity of each assemblage to covariables concerning deadwood and different land management ***:We found that all diversity indeces for plants were either negatively affected by the presence of deadwood on the ground,or favored by its *** mammals,removal of deadwood increased taxonomic diversity,while functional diversity increased with deadwood on the *** structural diversity of plants and functional diversity of mammals were greater in grazed ***:The sustainable use of woodland resources is essential for the activities of rural *** study results indicated that land management of grazed woodlands promoted the structural diversity of plant assemblages and the functional diversity of *** presence of deadwood negatively affected plant diversity but it increased mammal functional *** is a
