ECOLOGICAL NICHE MODELING AND WILDLIFE MANAGEMENT UNITS (UMAS): AN APPLICATION TO DEER IN CAMPECHE, MÉXICO

Abstract

The Units for the Conservation, Management and Sustainable Use of Wildlife (UMAs) are instruments of conservation and management of specific species in Mexico. UMAs represent in southeastern Mexico an important way for deer management, but they have major problems related to the monitoring of species. In this paper, we propose a methodology based on the use of a ‘niche centroid approach’ for estimating ecological distances to the niche centroid in order to produce distribution maps containing information on the potential relative abundance of species to evaluate the capability of UMAs to maintain populations of deers. We modeled the abundance for Mazama temama, M. pandora and Odocoileus virginianus on the state of Campeche, Mexico. Our predictions of areas with most abundance of deer coincided with reports from literature. We identified the UMAs “Ik Balam†and “Ejido Carlos Cano Cruz†as areas with high proportion of suitable environment, while UMAs “Betito y Lupitaâ€, “El Huanalâ€, “Puhâ€, “Refugio faunístico Jalotumâ€, “Ría Lagartos-Ría Celestun†and “Yocol Cab Balam†have not environmental conditions adequate to maintain deer populations. Although this is a preliminary study, it can be a starting point to establish institutional standards for the management of species.
