Factors Affecting Wild Turkey Recruitment in Western Virginia

Annual recruitment of eastern wild turkeys (Meleagris gallopavo silvestris) should be closely monitored to regulate fall turkey seasons and reduce risk of over-harvest. However, previous studies have not encompassed the spatial or temporal scales needed to produce models that can consistently predict recruitment over a large region. Our objective was to assess the ability of using long-term data sets of sex-age ratios, oak (Quercus spp.) mast, and weather variables to forecast annual wild turkey recruitment in western Virginia. We conducted a thorough literature search on factors believed...

Effect of Prescribed Burning of Clearcuts on Ruffed Grouse Brood Habitat

We evaluated short-term effects of prescribed burning of clearcuts on potential ruffed grouse (Bonasa umbellus) brood habitat in oak-hickory forests in western Virginia. We divided six <1-year-old clearcuts into two portions and designated one portion for prescribed burning during late fall or winter. Because of dry conditions, only four treatment areas were burned. We monitored habitat conditions on burned and unburned portions of clearcuts during the growing season preceding treatment and during the two subsequent growing seasons. Excessive coarse woody debris (CWD) can hinder...

Forest Clearings Management: Insects and Vegetation for Wild Turkey Broods

Insects and herbaceous vegetation important to young eastern wild turkeys (Meleagris gallopavo sylvestris) may be enhanced in forested areas by managing clearings. Natural resource agencies in Virginia and other eastern states have committed significant resources to create and maintain forest clearings to provide habitat for wild turkey broods in predominantly forested areas. However, techniques used to manage clearings often lack definitive ecological justifications. We compared effectiveness of 4 management regimes on forest clearings typical of those used by wildlife managers in the...

Effect of Habitat and Movement on Wild Turkey Poult Survival

Poult survival is an important factor in the dynamics of eastern wild turkey (Meleagris gallopavo silvestris) populations. We captured wild turkeys in western Virginia and monitored radio-tagged hens (N=26) to determine the effect of brood habitat, brood movements and brood range size on poult survival. Poult survival to 21 days post-hatch averaged 0.203 (SE=0.05) during 1992 and 0.418 (SE=0.11) during 1993 (T= 1.37, P>0.10). No correlations were detected (P≥0.10) between macrohabitat and forest cover type variables and poult survival. Poult survival was correlated with the percentage...

Estimating Carcass Fat Levels in Ruffed Grouse From Wing Fat

A technique for estimation of carcass fat levels in ruffed grouse (Bonasa umbellus) from wing fat levels is evaluated. The utility of this technique was investigated because many :Btate wildlife agencies annually collect grouse wings for purposes of age determination and hence wings are readily available. Mean wing fat (percent ether extract) levels were not significantly different than carcass fat levels in grouse collected in fall and winter. Significant differences were found between wing and carcass fat levels in spring (P < 0.10) and summer (P < 0.01) collected birds. Despite...
