The objective of this study is to present progress on management and conservation of with tailed-deer (Odocoileus virginianus) at the Mixteca poblana; an ethnic region whit 47 municipalities and 10,565.7 km 2 , whit semiarid and arid climates, rangeland slopes with tropical dry forest and xerophytes shrubs, where the Mexican subspecie of whitetailed deer mexicanus is distributed in 547,500 ha which represents 51.8% of the regionThe conservation and management of the deer is carried under the technological model denominated diversified livestock, a silvopastoril system which combines the intensive production of bovine meat, with the sustainable use of deer and other wildlife species and their habitat, by hunting and ecotourism in Units for the Management and Wildlife Conservation (UMAs). Under this management, there are 72 UMAs in 35 municipalities whit 82,522 ha in the region. The mexicanus subspecie is considerate as a hunt trophy by the Safari Club International. In the hunting season 2009-2010, 32 UMAs harvested 152 game permissions; 20 of those UMAs are located in Chiautla County. The deer is fed with 139 species of plants, mainly 40 herbs and 36 shrubs; the population density varies from 12.8 to 45.45 ha/deer. The environmental benefits from deer management and their habitat have resulted in environmental services such as conservation of soil, water and biodiversity. The socioeconomic benefits include increments in rate of incomes and regional employment, as well as conservation of cultural traditions. Actually in the region are involved three group of researchers, three Non Governmental Organization and seven and technical advisors.
