Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Honors Theses
Across the United States, bird populations have declined due to habitat loss. To better understand habitat use by birds, researchers observed populations at Jack Mountain Wildlife Management Area in southwest Arkansas. Students at Ouachita Baptist University surveyed 94 point count locations to estimate species diversity (total number of species observed) and species abundance (total number of individuals observed). At each point, students recorded the percentage of tree canopy cover, ground cover, midstory cover, and shrub cover. These variables were used as explanatory variables in multiple regression analyses to determine which variables were influential in explaining variation in species diversity and …

Bird Diversity And Abundance In Relation To Habitat Complexity At Jack Mountain Wildlife Management Area, Grace Tidwell
Honors Theses
Since 1973, North America has lost 2.9 billion birds due to habitat loss and fragmentation. To assess the effects of habitat complexity on bird diversity and abundance, 96 locations were surveyed at Jack Mountain Wildlife Management Area (WMA) using ten-minute point counts. All birds seen and heard at each point were documented, and habitat complexity was assessed by examining the percentage of ground coverage, shrub coverage, midstory tree layer, and canopy coverage at each point. A habitat complexity index was generated from these plant surveys. Previous research at Jack Mountain has shown that habitats dominated by pine trees had the …
