A vegetation and soil study was conducted on upland disposal sites of a 4,425- ha management area in Mississippi. This area comprised disposal sites managed for northern bobwhites (Colinus virginianus). The soil and subsoil materials of these disposal areas originated from vertical cuts of geological strata up to 54 m and contained acidic overburden. Soil samples were collected at 0- to 10-cm and >10- to 20-cm depths on 35 disposal areas. Soil pH values in 0- to 10-cm depths were not related to depths to overburden. Soil pH levels in >10- to 20-cm depths were related to overburden...

Emphasis on use of moist-soil management for waterfowl has increased in recent years. One component of this form of management which is not well documented are seed yields of many native plants produced. Seed yields of 4 moistsoil plant species were measured during the growing season of 1985 and 1986 on the Noxubee National Wildlife Refuge in Mississippi. Seed yields of 3 species, Polygonum hydropiperoides (Michaux), Polygonum densiflorum (Meissner), and Rhyncospora corniculata (Gray), were measured using a specially designed seed trap. The fourth species, Ludwigia glandulosa (Walter), was...

Although numerous studies have been conducted on food habits of the Northern bobwhite (Colinus virginianus), there is a paucity of information on food items taken by quail on severely-disturbed land bases. To collect more information, crop content analysis was conducted on 1,015 hunter-harvested northern bobwhites from 1982 to 1992. Quail were collected from disposal areas created by the deposition of spoil material during construction of the Tennessee-Tombigbee Waterway. These disposal areas are classified as severely-disturbed due to edaphic and pedogenic conditions. Vegetative cover was...

From December 1981 through July 1983, No.2 Kleflock snares, No.4 Victor leg-hold traps, and No. 330 Conibear traps were evaluated for beaver (Castor canadensis) control in Mississippi. No. 330 Conibears captured more (P < 0.10) beavers than did snares in dive sets and more (P < 0.01) beavers than any other set-type combination tested. The number of non-target species captured in snares was less (P < 0.01) than the number captured in either of the other devices. Economic analyses of vehicle, labor, and equipment costs/beaver captured showed No. 330 Conibears to be the least costly...
