Habitat Characteristics Associated with Burrows of Gopher Tortoises and Non-burrow Locations on a Mississippi Military Installation

SEAFWA Journal Volume 3, March 2016

Since the 1987 federal listing as threatened of western populations of gopher tortoises (Gopherus polyphemus), tortoise population recovery and habitat restoration efforts have been implemented at Camp Shelby Joint Forces Training Center, Mississippi. We studied plant community and edaphic features around tortoise burrows and at non-occupied locations in 2007. We investigated relationships between burrow presence and habitat characteristics through decision tree and logistic regression analyses. Burrow occurrence was positively related to stem counts of woody plants and species...

Economic Impacts of Onshore Fishing Sites and Fishing Tournaments on the Mississippi Gulf Coast

Our study attached a monetary value to marine resources associated with fishing on the Mississippi Gulf Coast. In 2001, we conducted on-site surveys (N = 475) to collect expenditures of marine onshore anglers and marine fishing tournament participants in the Mississippi Gulf Coast three-county region. We then determined the extent and economic impacts of these activities and integrated marine onshore angler economic impacts and attendances into a Geographic Information System (GIS) for the Mississippi Gulf Coast. Our survey response rate was 86%. Total sales impacts generated from fishing-...
