2004-05 Deer Harvest Report - Arkansas Game and Fish Commission
2004-05 Arkansas Game and Fish Commission Deer Season Summary Don’t forget to put your tag on it Hunters throughout Arkansas will recognize a lengthy addition to their big-game license this year – game tags. In an effort to streamline the hunting license system, the Arkansas Game and Fish Commission has initiated a new tagging format for big-game hunting. The new format enables hunters to police their own ranks more effectively and will benefit biologists with more accurate harvest totals. The new annual big-game license will include seven tags – three for the 2005 deer season, two for the fall 2005 turkey season and two for the spring 2006 turkey season. Other hunting licenses will have an appropriate number of tags depending on the license. All big-game licenses will expire June 30 each year. Hunters who bought licenses in the first six months of 2005 will receive a new license expiring June 30, 2006. Tagging your take Before you can move any big game harvested in Arkansas, you must remove the appropriate tag from your license and attach it to the ear or antler of a deer or leg of a turkey. The best method to attach the tag is with a standard household twist-tie. All game tags must be filled out legibly in ink and must remain attached until final processing and storage of harvested game. Hunters holding the 65 Plus License or the Disability License, hunters under 16 and Mississippi license holders hunting under the Reciprocal Hunting License Agreement must either use the tag below or a substitute tag displaying the hunter’s name, the date, time and zone number of the harvest. Non-resident hunters under 16 must purchase a license and replace their temporary tag with an official license tag after harvesting a deer. For more information on the new tagging system or to buy a license, call (800) 364-4263 (during normal business hours) or visit www.agfc.com. Arkansas Game and Fish Commission 2 Natural Resources Drive, Little Rock, AR 72205 GAME TAG INSTRUCTIONS · · · · · · · IMMEDIATELY after the kill and before moving the deer or turkey, the tag must be printed legibly in ink and securely fastened to the antler or ear on a deer and to the leg on a turkey. The game must be checked at an official check station within 24 hours of kill. Type of game: DD – Doe Deer; BB – Button Buck; BA – Antlered Deer; FT – Female Turkey; MT – Male Turkey Method: MG – Modern Gun; ML – Muzzle Loader; A- Archery; C – Crossbow Check Station # (or On line #) must be printed on the tag The tag must remain on the deer or turkey until final processing and storage by the hunter. If born after 1968, you must carry proof of Hunter Education training.

Executive Summary The 131,639 deer harvested in the 2004-05 deer season represent a 22 percent increase from the previous year’s harvest of 108,147. The buck harvest (72,563) increased 11 percent from the 2003-04 harvest of 65,607. The 46 percent increase in doe harvest (32,175 to 47,733) is a result of the doe bag limit increase in many parts of the state. The button buck harvest increased 15 percent (9,825 to 11,343). This is common when the doe harvest increases because some hunters may mistake a button buck for a doe. The 2005 herd health data showed kidney fat indices ranging from a low of 47 percent on Crowley’s Ridge to a high of 87 percent in the Arkansas River Valley. The peak period of conception was Nov. 20-27, 2004. The average number of fetuses produced was 1.7 per doe. The 2004-05 biological data demonstrates the majority of bucks (47 percent) and does (30 percent) harvested statewide were 2.5 years old. This is primarily the result of the three-point rule started in 1997. Average dressed body weights for adult bucks ranged from 107 pounds in the West Gulf Coastal Plain to 130 pounds on Crowley’s Ridge. Average adult doe dressed weights were highest on Crowley’s Ridge (94 pounds) and lowest in the Ouachita Mountains (74 pounds). Statewide lactation rates in adult does were below the minimum acceptable value of 80 percent. The highest adult lactation was 77 percent in the Ozark Mountains; the lowest adult lactation was 53 percent in the Ouachita Mountains. Antler index is the sum of main beam circumferences, main beam lengths, number of points, brow tine lengths and inside spread. The highest average score was 43.8 on Crowley’s Ridge; the lowest was 39.1 on the West Gulf Coastal Plain. 1 Section One: Harvest Results Harvest Results for 2004-05 The overall statewide deer harvest for the 2004-05 season was 131,639, a 22 percent increase from the 2003-04 harvest of 108,147. The overall buck harvest increased 11 percent from 65,607 in 2003-04 to 72,563 in 2004-05. This is most likely the result of improved weather conditions and a visible rut. The 46 percent increase in the doe harvest from 32,175 in 2003-04 to 47,733 in 2004-05 was most likely because of the doe bag limit increase in many parts of the state.

Note: Zone totals may not match the statewide total because of check sheets with incorrectly recorded zones. 5 Section One: Harvest Results Statewide Harvest by Date The 2004-05 deer season was the second season that scannable check sheets were used. In addition to ease of use, faster data processing and almost real-time data reporting, the scanning process enabled the AGFC to analyze the deer harvest by date. This information will allow the agency to chart opening day trends. It also will provide valuable details about the effects of season structure on the harvest. The most noteworthy finding from the 2004-05 harvest by date was that 20 percent of the total harvest (25,390 out of 130,306) occurred during the opening days of the muzzleloader and modern gun seasons, and almost 30 percent (38,057 out of 130,306) occurred during the opening weekends of muzzleloader and modern gun seasons.

Deer Management Units The 1999 Strategic Deer Management Plan defined Deer Management Units (DMU) based on the following Arkansas physiographic regions: Ozark Mountains, Ouachita Mountains, Arkansas River Valley, West Gulf Coastal Plain, Mississippi Alluvial Plain (Delta), and Crowley’s Ridge (see Map 1). The Strategic Deer Management Plan established long-term deer biological and population goals for each DMU. The statewide deer zones are subdivisions of the DMUs. Zones allow separate management strategies to address differences in deer populations, harvests, habitats and land use within each DMU to maintain the established population and biological goals. Map 1 7 Section One: Harvest Results Harvest Density Using Geographic Information Systems (GIS) technology, the AGFC analyzed the 2004-05 deer harvest by total acreage for the DMUs and Wildlife Management Areas (WMA). The West Gulf Coastal Plain DMU was the most productive, with a yield of one deer harvested for every 127 acres (see Map 2). Choctaw Island WMA was the most productive with a yield of one deer for every 28 acres. At the county level, biologists analyzed the harvest by acreage of deer habitat, defined as any habitat minus urban areas, row crops and standing water. Although Union County had the highest total harvest at 5,812, Prairie County was the most productive per acre of deer habitat with a yield of one deer harvested for every 49 acres of deer habitat (see Map 3). Some WMAs experienced dramatic increases in the buck harvest from the 2003-04 season. The majority of the increases can be attributed to noncompliance with deer-checking requirements.

Samples are collected from all six Deer Management Units. This data gives biologists important information about herd health, timing of the rut and fawn production. Herd health checks have been conducted for four years, and more than 1,300 samples have been collected. All usable meat was donated to Farmers and Hunters Feeding the Hungry or families within the community. Kidney Fat Index: Kidney Fat Index (KFI) can be used to evaluate physical conditions of deer coming out of the winter stress and entering spring green-up. KFI is the weight of the fat deposits surrounding the kidneys divided by the weight of the kidneys, and is expressed as a percentage. The higher the KFI value, the healthier the deer. Targets for KFI change with the season, but for February the target is 35 percent. Conception Date: Fetuses are extracted and measured using a JIM-GEM fetus scale to determine days from conception and days to birth. Conception data provides “peak rut” dates, which assist biologists in making management decisions such as setting deer season. Conception dates vary from year to year and are dependent on population density. Ideally, adult does should breed during their first estrus cycle (November), which results in fawns born during early summer (June). Fawns born during July and August have decreased survival rates because of poor habitat conditions and extreme heat. Fetal Counts: The number of fetuses per doe is a measure of breeding success and health of the animal. The number of fetuses per yearling doe is slightly lower than the number among adults, but this is common because of the developmental stage of yearling does. There is little regional variation for this among DMUs, which indicates breeding success is uniform across the state. The goal for fetal counts is 1.7 fetuses per doe. 13 Section Two: Herd Health Reports 14 Section Two: Herd Health Reports 15 Section Two: Herd Health Reports 16 Section Three: Biological Data Reports Biological Data Collection AGFC wildlife management employees and participating deer clubs collect a variety of data from harvested deer each season. Data collected includes age, body weight, antler measurements and lactation rates. These indices make it possible to analyze differences in biological characteristics of Arkansas’ deer over time and between DMUs. Age Structure: Average age structure is directly related to harvest. Buck age structure depends on harvest criteria such as the three-point rule. Before the three-point rule was implemented, 80 percent of bucks harvested were yearlings. Among does, the average age harvested provides information on the age structure and potential population growth. Dressed Body Weight: Average dressed body weights can vary depending on environmental conditions such as soil fertility, weather conditions and available mast. Bucks can experience extreme loss in body weight during the breeding season because rutting activity causes them to focus less on eating and more on establishing territories and monitoring receptive does. Body weights among does also fluctuate throughout the year because of gestation requirements, lactation and available food. The target for average buck dressed weight is 110 pounds, except in the Mississippi Alluvial Plain, where it is 130 pounds. The target dressed weight for does is 80 pounds across most of the state, 90 pounds in the Mississippi Alluvial Plain. Antler Index: Antler index is the sum of the main beam lengths, main beam circumferences, total number of points, brow tine lengths and inside spread. Antler indices vary by region and within DMUs, depending on environmental conditions such as nutritional foods available. Other factors include age and genetics. Lactation: Lactation is an indicator of a bred doe. Lactation rates tend to be much higher in adult deer (2.5-plus years old) than in yearling deer (1.5 years old). Lactation figures represent lactation data collected during October and November to ensure accurate determinations. Target lactation is 80 percent for adults and 25 percent for yearlings. 17 Section Three: Biological Data Reports 18 Section Three: Biological Data Reports 19 Section Three: Biological Data Reports 20 Section Three: Biological Data Reports 21 Section Three: Biological Data Reports 22 Section Four: Deer Hunting Accidents 2004-05 Deer Hunting Accidents By County During the 2004-05 season, 17 deer hunting incidents were reported. Eleven involved the discharge of a firearm; nine resulted in injury and two were fatal. Six accidents involved individuals who fell from deer stands; none was fatal. Map 5 23 Section Five: Bowhunter Observation Data 2004-05 Bowhunter Observation Data by DMU Table 7 The 2004-05 archery season was the first in which hunters from across the state collected deer observation data. Hunter observations provide population data such as sex ratios, deer density, fawn-to-doe ratio and antler structure. This kind of population data, along with biological data from harvested deer, provides a more detailed picture of the deer herd for each region. Almost 1,100 archery hunters in the survey collected more than 18,500 hours of data. It is important to stress that the information below represents only a year of observation data. Additional data will be needed to determine trends and potential change related to management strategies.

It is characterized by poor body condition, behavioral abnormalities and death. CWD is classified as a transmissible spongiform encephalopathy (TSE), and is similar to mad cow disease in cattle and scrapie in sheep. Infectious agents of CWD are neither bacteria nor viruses. They are believed to be prions, infectious proteins that lack associated nucleic acids. Although CWD is a contagious fatal disease among deer and elk, research suggests humans, cattle and other domestic livestock are resistant to the disease. While the possibility of human infection remains a concern, there have been no verified cases of humans contracting CWD. CWD can reduce the growth and size of wild deer and elk populations in areas where it is prevalent, and it has become an increasing concern for wildlife managers across North America. The disease was long thought to be limited in the wild to a relatively small area in northeastern Colorado, southeastern Wyoming and southwestern Nebraska. However, it recently has been found in several other areas across the continent. The disease also has been found in commercial game farms in several states and provinces. Arkansas began surveillance for CWD in 2003. To date, 2,678 wild deer samples have been tested in USDAcertified labs at the Arkansas Livestock and Poultry Commission and the University of Georgia. No evidence of CWD has been detected in any of these samples. Testing will be completed in every Arkansas county by March 2006. This effort is being made in cooperation with the Arkansas Livestock and Poultry Commission and the USDA Animal and Plant Health Inspection Service. During the last two years, cooperating deer clubs and individual hunters provided the majority of the samples tested in Arkansas. These hunters allowed AGFC biologists to extract tissue specimens from harvested deer at state check stations. The effort to prevent CWD and to conduct surveillance would not be possible without the cooperation of these hunters. If you know of a deer with symptoms of CWD (extremely poor appearance, excess salivation, lack of coordination or drooping ears), contact AGFC toll-free at (800) 440-1477.

The area is near Arkansas City in Desha County in southeastern Arkansas. The area includes two tracts separated by a portion of the old Mississippi River (see map below), both of which lie within the Mississippi River levee system. The mainland tract (5,729 acres) is bottomland hardwoods dominated by sugarberry, box elder, cottonwood, sycamore and pecan. The island tract (1,947 acres) has species such as black willow and sugarberry. Recreation Map 8 Choctaw Island always has been noted for its potential as a deer-hunting area. The intensive timber management, combined with former rowcrop agriculture, created a highly productive habitat for white-tailed deer. Fishing is another popular pursuit on Choctaw Island. Pothole and Kate Adams lakes are highly prized by anglers for their crappie fishing. Several other oxbow lakes and borrow pit areas also are popular fishing sites. Deer Research Area Soon after the acquisition of Choctaw Island WMA, members of the AGFC’s Region 3 wildlife management staff provided a formal presentation to the Commission requesting that Choctaw Island be used as the AGFC’s first Deer Research Area. This request was based, in part, on ongoing efforts in Region 3 to trap and ear tag deer for later identification. Increasing interest in deer management associated with the Deer Management Assistance Program also played a key role in this decision. The need for deer research also was identified and supported in the AGFC’s 1999 Strategic Deer Plan. 27 Section Seven: Deer Management Deer Trapping and Tagging Efforts Wildlife management personnel have trapped and tagged more than 40 deer on Choctaw Island WMA. This effort has allowed field staff to monitor and identify individually tagged deer from deer harvest, hunter observations and motion camera photographs. The objectives of the tagging effort are to allow Region 3 field staff to: • monitor antler development across age classes, • test the reliability of aging by tooth wear/replacement, and • maintain the ability to recover older age class, radio-collared bucks that have succumbed to either natural or hunter-induced mortality. Deer Population Density Estimates Motion Camera: Two surveys using fixed, motion-detecting cameras were conducted in January 2003 and 2004. Forty-eight cameras in 2003 and 45 cameras in 2004 were placed in 100-acre grids and monitored for five consecutive days. Methods for determining deer densities were based on the ratio of identifiable, branched-antlered bucks to total bucks photographed. These ratios were applied to mathematical formulas to predict buck, doe and fawn densities. Using this sampling method, deer density estimates for Choctaw Island were 15.6 acres per deer for 2003 data and 17.1 acres per deer for 2004 data (mainland area only). Thermal Infrared Videography: In 2003, the University of Arkansas at Monticello (UAM) and AGFC personnel conducted two thermal imaging flights. This sampling method uses a video camera capable of detecting heat emitted from deer. The heat signature is represented on video as a highly visible white dot, which can be recorded and counted as an individual deer. The sample area is divided into grids that are videotaped from an airplane to maintain a relatively uniform sample. The deer density is calculated based on the number of deer heat signatures recorded and the total acreage sampled. Typical deer heat signatures identified in thermalimaging surveys on Choctaw Island WMA. The density estimates for these flights averaged 7.4 acres per deer (n=788) on the mainland and 38.4 acres per deer (n=30) on the island. The flights were repeated in 2004, and the postharvest density estimates were 8.9 acres per deer (n=665) on the mainland and 14.9 acres per deer (n=75) on the island. 28 Section Seven: Deer Management Observation Data Hunter observation data has been collected during the last two years. The objective of collecting this data has been to monitor trends in deer numbers, buck-to-doe ratios, fawn-to-doe ratios, buck antler development in tagged deer and hunter success. The following is a summary of the 2003 Choctaw Island WMA Hunter Observation Data. (Note: 2004 observation data is being analyzed). Number of Hunter Hours = 5,750 Number of Deer Observed = 5,291 Deer Observed/Hour Hunt Time = 0.92 Observed Buck-to-Doe Ratios = 1:1.7 Fawn Recruitment = 51 percent Number of Deer Shot, Hit and Not Recovered = 43 Number of Hunters Observed per Hour Hunted = 0.2 29 Section Seven: Deer Management Harvest Data The 2003 deer season was the first since the acquisition of the Choctaw Island Deer Research Area. Considering only 9 percent of the bucks recorded on the Hunter Observation Forms exceeded eight points, the five-point rule (on one side) restriction significantly limited the buck harvest.

This, combined with the option to harvest a Type B (management buck) resulted in a substantially higher buck harvest for 2004.

These antler restrictions are tailored to this area and will allow biologists to try new management techniques after collection of additional data. 30 29 Acknowledgements Doyle Shook Chief, Wildlife Management Division Cory Gray Deer Program Coordinator Jeff Johnston Data Management Program Coordinator Hanna Ford Programs Support Jeff Williams Editor Randy Zellers Editor Angela Browner Senior Designer 31 www.agfc.com 2 Natural Resources Drive Little Rock, AR 72205 (800) 364-4263
