Management/Monitoring recommendations:Continue current management and harvesting practices (limited spring harvesting, Wild Turkey brood survey).Causes of change since first Atlas: Continued expansion of population following earlier reintroduction program.VT’s role in North American range: VT is in the northeastern corner of the range.
Data from other research: No additional data for VT.Greatest increases in Northern Green Mountains and Northern Vermont Piedmont. Status in VT: Increased by 314% (35 to 145 blocks).population is annually contaminated by lead poisoning (Ariz. Vermont Center for Ecostudies – Vermont Atlas of Life.

We concluded line-transect–based distance sampling from roads is an efficient, effective, and inexpensive technique for monitoring Rio Grande wild turkey populations across large scales.Renfrew, R. During winter surveys, power was sufficient (≥0.80) to detect a 10–25% change in population density in 8–12 years using ≥100 16-km transects or ≥80 32-km transects. Winter surveys tended to have less bias, lower relative variability, and greater power than did autumn surveys. The population density in Turkey is 112 per Km 2 (289 people per mi 2). Turkey ranks number 18 in the list of countries (and dependencies) by population. Turkey population is equivalent to 1.07 of the total world population. Such bias occurred because of incomplete detectability of flocks near roads. Turkey 2023 population is estimated at 85,816,199 people at mid year. Simulations suggested that population density may be underestimated by 12% during winter and 29% during autumn. We conducted computer simulations to evaluate the performance of line-transect–based distance sampling and examined the power to detect trends in population change. The detection probability of decoy flocks was similar to wild turkey flocks during winter (decoy flock, 69.3 ± 6.2% wild turkey flock, 62.2 ± 18.3%) and autumn (decoy flock, 44.1 ± 5.1% wild turkey flock, 44.7 ± 25.6%), which suggested that using decoys was appropriate for evaluating detectability of wild turkey flocks from roads. We also conducted surveys from roads for wild turkeys during November 2004–January 2006.
Our modeling effort suggested that distance to a flock and flock size played important roles in flock detectability. The wild boar population density was estimated using a dataset available at FAO, including hunting and census data available from different sources and at different level of administrative units, for a total of 46 countries and 509 sub-national units (Fig 1 and S1 Table).
We evaluated detectability of flocks using logistic regression models. declines in wild turkey population size, and noted corresponding declines in both spring harvest of males and a reduction in hunters participating in spring hunting. Wild boar population data and geographic extent. We used inflatable turkey decoys during autumn (Aug–Nov) and winter (Dec–Mar) 2003–2005 at 3 study sites in the Texas Rolling Plains, USA, to simulate Rio Grande wild turkey ( M. Line-transect–based distance sampling has been used to estimate density of several wild bird species including wild turkeys ( Meleagris gallopavo).
