Pronghorn
Aerial Surveys
Panhandle herd units colored red with surplus pronghorn populations used for restocking, 2013 and 2014.
In 2013, the estimated Panhandle pronghorn population was 12,831, including fawns
In 2013, the estimated Trans-Pecos pronghorn population was 3,071, including fawns
Trans-Pecos herd units. Red units are where pronghorn were transplanted in 2013 and 2014.
Bighorn Sheep
Free-Ranging Bighorn Sheep Observations from Helicopter Surveys 2001-2013.
* Portions of mountain ranges were not included in survey or no survey was conducted. ** Sheep observed in ground surveys. *** No survey was conducted during reporting period. Monitoring efforts will be discontinued because economically unfeasible. **** No surveys were conducted because mountain range was uninhabited by bighorn sheep.
In the mid-1990’s the population of free-ranging elk in the Trans-Pecos was estimated at 325 individuals. The estimates are as follows: 40 in the Davis Mountains, 30 in the Wylie Mountains, 30 in the Eagle Mountains, 170 in the Glass Mountains, and 40 in the Guadalupe Mountains. The range of the Glass Mountain herd continues to expand southward into the adjacent Del Norte Mountains. The Panhandle herd remained constant at 15 individuals.
Based on Breeding Bird Survey data, the Texas turkey population has grown considerably over the past ten years and appears to still be growing. The Texas turkey population is estimated to exceed 500,000 birds.

• The last survey of medium to large-sized exotic mammals and birds was conducted in 1988.
• At that time there were an estimated 67 species of exotics totaling 164,257 confined, or free-ranging animals, statewide (not including feral hogs).
• The majority were located in the Edwards Plateau and South Texas Plains.
Exotics
Feral Hogs • The estimated statewide feral hog
population is approximately 3.5 – 4.0 M.
• Approximately 45,000 hogs are killed annually by Texas Wildlife Services and aerial control agents

ABSTRACT In 2014, 163, 20-mile quail survey lines were conducted in August. The mean number of bobwhite quail observed/ecological region was as follows: Gulf Prairies 19.90, Cross Timbers 1.34, South Texas Plains 11.59, Edwards Plateau 4.88, Rolling Plains 7.53 and the High Plains 5.89. The mean number of scaled quail observed/ecological region was as follows: Trans-Pecos 6.00, South Texas Plains 0.88, Edwards Plateau 2.63, Rolling Plains 0.55 and the High Plains 0.09. Also based on roadside surveys, a total of 83 bobwhite broods and 14 scaled quail broods were observed. The mean bobwhite brood size was 11.10, and the mean scaled quail brood size was 11.18. In 2013-2014 hunting season, 31,568 quail hunters harvested 220,502 bobwhite quail and 10,516 hunters harvested 100,063 scaled quail.
ABSTRACT Based on Breeding Bird Survey data, the Texas turkey population has grown considerably over the past ten years and appears to still be growing. The Texas turkey population is estimated to exceed 500,000 birds. Statewide harvest data is obtained through the Texas Parks and Wildlife Department (TPWD) Small Game Harvest Survey. Approximately 87,846 hunters harvested 38,839 wild turkeys during the combined 2013-2014 spring and fall turkey seasons. If our estimates are accurate, the statewide harvest is about 7.8% of the statewide population. During the 2013 spring season, 55,194 hunters harvested 19,941 wild turkeys. During the 2013-2014 fall season 54,753 hunters harvested 19,066 wild turkeys. The Eastern turkey population is estimated to be approximately 10,000 birds. The Eastern turkey is historically the only game animal in Texas with mandatory reporting following harvest. All harvested birds must be reported to one of TPWD’s eastern turkey check stations within 24 hours of harvest. Check stations are distributed in each county with an open eastern turkey season. During the FY2014 Commission cycle, the TPWD Commission approved the use of an electronic checking system for reporting Eastern turkey harvest “My Texas Hunt Harvest”. The My Hunt Harvest app is available for download on both Apple and Android devices. Hunters can also report their harvest online at http://tpwd.texas.gov/turkey. My Hunt Harvest also provides hunters an opportunity to provide voluntary harvest data for all other resident game species. Check Station data from the 2014 Eastern turkey season identified 203 wild turkeys harvested. This harvest estimate is up approximately 10% from the 2013 Eastern turkey season, yet still about 13% below the 8 year average. Data from the 2015 season has not yet been analyzed.
