Physical Characteristics for Age Estimation of Male White-tailed Deer in Southern Texas

Criteria for visually estimating age of live white-tailed deer (Odocoileus virginianus) in the field are becoming more important as the popularity of non-traditional deer management programs increase. We measured gross Boone and Crockett Club (BCC) score, number of antler points, inside antler spread, main beam length, antler basal circumference, chest girth, stomach girth, shoulder height, head length, and interorbital width and evaluated which characteristics had the greatest potential for use as predictors of age for <766 live-captured males and live and dressed mass for <65...

Mass Estimation of White-tailed Deer in Southern Texas

Predictive equations based on various body measurements have provided wildlife managers with practical and reliable estimates of deer mass, but have not been reported for white-tailed deer (Odocoileus virginianus) in the Western Rio Grande Plain region of Texas, nor for male white-tailed deer in Texas. To address this need, we assessed relationships among live mass and dressed mass, chest girth, shoulder height, hoof length and width, and gross Boone and Crockett Club (BCC) score. Regression analyses indicated live mass of mature (>5.5 years old) males can be predicted with a model...

Avian Nest Success in Growing and Dormant Season Burned Pine Forests of Georgia

Prescribed fire is a commonly used land management tool in pine (Pinus spp.) forests of the southeastern United States to control understory vegetation and enhance wildlife habitat for early successional species, but its effects on the nesting success of understory and ground-nesting songbirds are not well understood. We compared the effects of growing and dormant-season prescribed burns on the nesting success of six ground- or shrub-nesting bird species in mature pine stands at one and two years post-treatment at Fort Benning Military Reservation in Chattahoochee and Muscogee counties,...

Habitat Associations of Bats in South-central West Virginia

Wildlife Outstanding Technical Paper

We conducted acoustic surveys at National Park Service and state park properties in south-central West Virginia to create bat habitat association models across a large, topographically complex and relatively intact Appalachian Hardwood landscape representative of the Allegheny Plateau portion of the central Appalachians. We developed generalized and species-specific groups of a priori habitat association models to predict bat presence using various microhabitat and landscape features linked to body-size, wing morphology, food habits and echolocation call characteristics for seven species....

Effect of Roads and Traffic on Deer Movements in a Georgia Park

Effects of traffic volume on white-tailed deer (Odocoileus virginianus) movement patterns and behavior have not been well documented. During summer 2004, we monitored survival and home ranges of 34 radiocollared deer (6 males and 28 females) in a heavily visited state park in Georgia to determine effect of road distribution on home range use. We also monitored hourly movements for eight females in relation to daily patterns of vehicle volume within the park. Although deer behavior was altered by frequent exposure to traffic and roadside feeding of deer by park visitors, no deer were killed...

A Quantitative Evaluation of the Severinghaus Technique for Estimating Age of White-tailed Deer

Subjectivity of tooth wear and replacement (i.e., Severinghaus technique) for estimating ages of white-tailed deer (Odocoileus virginianus) is sometimes questioned. To further quantify Severinghaus's description of tooth wear, we used digital photographs and computer-assisted technologies to measure dentine and enamel widths on molars of 67 wild, known-aged deer from South Carolina. Accurate measurements of dentine: enamel ratios did not clearly separate 2.5, 3.5, and 4.5-year-old deer because of excessive variability within age classes. Therefore, we used K-nearest neighbor [KNN] analysis...

Forage Production, Use by White-tailed Deer, and Seasonal Crude Protein Level of Three Cool Season Forages in Georgia

In the southeastern United States, food plots are often used to compensate for annual fluctuations in forage quantity and quality. We evaluated forage production, seasonal use by white-tailed deer (Odocoileus virginianus), and seasonal crude protein levels of MaxQ fescue (Festuca arundinacea), Regal ladino white clover (Trifolium repens), and Durana white clover (T. repens) planted alone or in combination. We planted two 1-ha food plots in the Coastal Plain, Piedmont, and Blue Ridge physiographic regions of Georgia in November 2002. We measured forage production (kg/ha) and use every 30 (±...

Daily Movements of Female White-tailed Deer Relative to Parturition and Breeding

To assess how white-tailed deer (Odocoileus virginianus) herd demographics influence reproductive behaviors, we examined 24-h diel movements of female white-tailed deer relative to parturition and breeding in a low-density population with a near even sex ratio at the Savannah River Site (SRS), South Carolina. We conducted a series of intensive, 24-h radio-tracking periods of 13 females during spring and fall 2002. We compared daily range (ha), rate of travel (m/h), and distance between extreme daily locations (m), among the periods of pre-parturition and post-parturition and pre-, peak-,...

Effects of Thinning and Herbicide Application on Vertebrate Communities in Longleaf Pine Plantations

Currently, nearly 98% of the land area once dominated by longleaf pine ecosystems has been converted to other uses. The U.S. Forest Service is replanting logged areas with longleaf pine at the Savannah River Site, New Ellenton, South Carolina, in an effort to restore these ecosystems. To ascertain the effects of various silvicultural management techniques on the vertebrate communities, we surveyed small mammal, herpetofaunal, and avian communities in six 10- to 13-year-old longleaf pine plantations subjected to various thinning and herbicide regimes. Areas within each plantation were...

Effects of Controlled Dog Hunting on Movements of Female White-tailed Deer

Understanding the responses of white-tailed deer (Odocoileus virginianus) to controlled dog hunting can aid in the effective implementation of canine-assisted population management strategies. We examined the 24-h diel movements of 13 radio-collared female deer exposed to dog hunting on the Savannah River Site (SRS) near Aiken, South Carolina, where regulated dog hunting has occurred since 1965. We compared diel home range size, rate of travel, and distance between extreme diel locations before, during, and after hunts from 14 September-14 December 2002. Diel home range size (F2,91 = 7.71...
