Abstract/Summary:
Camp Maxey is a military facility in Lamar County, Texas. The vegetation and mammal populations of Camp Maxey were surveyed in 26 different plots throughout the base in 2005. Ecological vegetation types were determined on the basis of DCA ordination and TWINSPAN classification of the collected floristic data and observed physical attributes. Three hundred thirty nine plant species were recorded and eight vegetation types were identified. Nine rodent species were identified in this survey. Rodent species richness was similar among vegetation types, however, there was a significant difference (p<0.05) in captures and relative abundance between vegetation types. Capture numbers of any species were not correlated with physiographic characteristics of the stand, but some species appeared to be related to the presence of certain plant species. This study contributes to the continuing ecological classification of community types within the facility and provides some insights on mammal habitat use.
