Determining Body Mass of Wild Pigs from Body Measurements

SEAFWA Journal Volume 11, March 2024

Animal body mass can be used to estimate age, determine health status, or guide dosage when administering sedatives. Because it can be difficult to weigh live large animals, using morphometric measurements to estimate body mass is sometimes used in field studies. Several statistical models exist for estimating domestic pig mass from morphometric measurements, but models based on domestic animals are likely unreliable estimators of wild pig (Sus scrofa) body mass due to known hybridization between domestic and wild pigs, and variable environmental conditions. The goal of this...

Impact of Invasive Wild Pig on White-Tailed Deer and Eastern Wild Turkeys in Southwest Georgia

SEAFWA Journal Volume 11, March 2024

Wild pigs (Sus scrofa) are a highly destructive invasive species and reported to be present in 77% of counties in the southeastern U.S. Wild pigs may negatively affect white-tailed deer (Odocoileus virginianus; hereinafter, deer) and eastern wild turkeys (Meleagris gallopavo silvestris; hereinafter, turkey) via competition over forage or exclusion from preferred areas. To explore effects of wild pigs on spatial distribution of these species within a mixed agriculture-forest landscape, we developed models predicting camera trap detections of deer and turkeys as a...

Habitat Characteristics of Eastern Wild Turkey Nest and Ground-roost Sites in 2 Longleaf Pine Forests

SEAFWA Journal Volume 2, March 2015

Managing and restoring longleaf pine forests throughout the Southeast is a conservation priority. Prescribed fire is an integral part of these activities, as it is the primary means of controlling hardwood encroachment and maintaining native groundcover. Nest site and preflight brood ground- roost site selection of eastern wild turkeys (Meleagris gallopavo silvestris) has not been well studied in longleaf pine systems. Therefore, we determined habitat characteristics associated with wild turkey nests and ground-roosts in 2 longleaf pine forests in southwestern Georgia. We radio-tagged 45...

Coyote and Bobcat Predation on White-tailed Deer Fawns in a Longleaf Pine Ecosystem in Southwestern Georgia

SEAFWA Journal Volume 2, March 2015

Managing white-tailed deer (Odocoileus virginianus) populations requires an understanding of fawn survival and cause-specific mortality. In the Southeast, coyotes (Canis latrans) and bobcats (Lynx rufus) can be major sources of fawn mortality and may limit some white-tailed deer populations. We captured and radio-collared 47 fawns at the Joseph W. Jones Ecological Research Center in southwestern Georgia during 2007, 2008, 2011, and 2012 to quantify cause-specific mortality and survival. Fawn survival to 20 weeks of age (i.e., opening day of firearms season) was 29.0%. Coyote predation...

Effects of Growing-season Prescribed Fire on Eastern Wild Turkey Nest Survival, Nest Success, and Poult Survival in Southwestern Georgia

We investigated effects of growing-season prescribed fire on daily nest survival, nest success, and poult survival of eastern wild turkeys (Meleagris gallopavo silvestris) on two similar research sites in southwestern Georgia: the Joseph W. Jones Ecological Research Center and Silver Lake Wildlife Management Area. We collected daily locations for radio-tagged females throughout the 2011-2012 nesting seasons. Females with nests or poults near or within an active growing-season fire were located hourly. We estimated poult survival using flush counts and incidental sightings until poults...

Effects of a Supplemental Food Source and Nest Density on Success of Artificial Ground Nests

Nest predation can limit avian recruitment and may be a proximate source of population declines in many avian populations. Because nest predation may be affected by availability of alternative foods and nest density, we used artificial nests and track counts to evaluate effects of supplemental food and nest density on nest success of artificial ground nests. Nest success was lower at 7 of 9 nest density classes when a supplemental food source was present. In the absence of supplemental food, nest success was inversely related to nest density, but when supplemental food was present,...

Predator Removal and White-tailed Deer Recruitment in Southwestern Georgia

We assessed the efficacy of predator removal as a tool for increasing white-tailed deer (Odocoileus virginianus) recruitment at the Joseph W. Jones Ecological Research Center in southwestern Georgia, an area with a low-density (2-6 deer/km2) deer herd. We partitioned our 11,736-ha study area into predator removal (approximately 4,200 ha) and non-removal (approximately 2,800 ha) zones with a 4,500-ha buffer between them. We removed 23 coyotes (Canis latrans) and 3 bobcats (Lynx rufus) from the removal zone between January and August 2008. Most of these (14 coyotes and 1 bobcat) were...

Bat Community Structure and Activity in Longleaf and Loblolly Pine Forests of Southwest Georgia

The area of longleaf pine (Pinus palustris) forests have declined whereas intensive pine (Pinus spp.) silviculture has increased on the southeastern landscape. Because effects of differing pine management scenarios on bat community structure and activity are largely unknown, we used mist nets and acoustic surveys to examine these factors on mature longleaf pine and intensively managed loblolly pine (P. taeda) landscapes in southwestern Georgia. We placed mist nets over ponds, small streams, and roadside ditches and placed bat detectors in replicates of four vegetation types (open, closed...

Seasonal and Annual Home Ranges of Female Eastern Wild Turkeys in a Managed Pine Landscape in Mississippi

Eastern wild turkeys (Meleagris gallopavo silvestris) are an important recreational resource throughout their range. Previous research has shown that intensively managed pine forests can sustain huntable populations of eastern wild turkeys. However, little research has examined patterns of spatial use of turkeys within these systems. An expected increase in acreage of intensively managed pine forests over the next half century requires a basic understanding of wild turkey ecology in these systems. Therefore, we used a long-term (1986-1993) data set to estimate annual and seasonal home...

Habitat Use of Bobcats at Two Spatial Scales in Southwestern Georgia

Habitat needs of wildlife are important for science-based wildlife management. Further, these needs may differ based upon the ecosystem in which the species lives. Bobcat habitat use within the longleaf pine (Pinus palustris) forest ecosystem has received little attention. Therefore, we monitored 21 bobcats (Lynx rufus) (8 M, 13 F) during 2001-2002 in southwestern Georgia to determine habitat use at two different spatial scales: (1) habitat associated with each animal's locations relative to habitat composition of its home range and (2) habitat composition of each bobcat's home range...
