Book Population Ecology and Habitat Relationships of White tailed Deer in Eastern Montana

Download or read book Population Ecology and Habitat Relationships of White tailed Deer in Eastern Montana written by James D. Herriges (Jr.) and published by . This book was released on 1986 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted using radio telemetry to evaluate distribution, movements, activity, and habitat use by white-tailed deer (Odocoileus virginianus) on two areas along the lower Yellowstone River in eastern Montana during summer 1982 and 1983 and winter 1984. Deer distribution centered on river bottomlands, though some deer made daily or seasonal movements to adjacent uplands on the Intake area. Deer movements were short and restricted to riparian cover during the day, but increased and extended to agricultural fields up to 2.5 km from cover at night. Movement to and use of fields increased through summer and from summer to winter and appeared greater on the Intake than Elk Island study area. Well defined peaks in deer activity and movement occurred at sunrise and sunset; lesser peaks occurred near midnight and noon. Peak use of agricultural fields occurred from 1-2 hours after sunset until midnight. Seasonal minimum convex polygon home range sizes for individual deer varied from 0.29 km^2 to 10.0 km^2. Adult females had the smallest home ranges, averaging 0.87 km^2 in summer and 1.8 km^2 in winter. Total (24-hour) home range size varied by sex and age of the deer, season, and study area. Home ranges based only on daytime relocations averaged half as large as total home ranges in summer and 28% of the total in winter and did not differ between seasons and study areas. Among riparian cover types, deer selected for mid-to-late seral communities (mature cottonwood, shrub, green ash, and mature willow) with tall dense cover; grasslands were avoided. Among croplands, deer preferred alfalfa in summer and ungrazed alfalfa, sugar beets, and winter wheat in winter. Differences in selection and use of crops between study areas and seasons were related to availability influenced by cropping, harvest, and post-harvest grazing and field treatment practices. Overall, natural riparian cover and agricultural croplands were the two major components of deer habitat. These combined with topography and physiography of the river valley, and other land use and operational practices to influence deer distribution movements and home range size, activity, and use of specific cover types. --Abstract.

This book was released on 1974 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the life history, population dynamics, and ecological relationships of the Columbian white-tailed deer (Odocoileus virginiarius leucurus) was conducted on the Washington mainland, Columbian White-tailed Deer National Wildlife Refuge during 1972-1973 to provide information for management of this endangered subspecies. A total of 18,077 observations of deer recorded during 213 morning and evening periods along two observation routes provided information concerning use of plant communities, activity, group composition, and sex and age structure. Detailed behavior observations were recorded during 25 morning and evening periods. Vegetation on the study area was categorized into five major community groupings of rush, thistle, grass, horsetail, and forest Deer were observed most often in those communities that provided both cover and forage. Communities providing forage without cover were most used where cover was adjacent. The population on the study area during the winter was estimated between 200 and 230 deer or one, deer per 3.4-3.9 hectares (one deer per 8.5-9.8 acres). A buck:doe:fawn ratio of 34:100:35 was calculated for November. Average group size of deer while grazing was 2.2 animals The major classification of group size throughout, the year was of single deer. Numbers of individuals within groups were highest during winter. Overt aggression between individuals was observed infrequently. Frequency of aggressive behavior was greatest during cold weather. Bucks were always dominant over does and fawns, and does were always dominant over fawns. Grazing was numerically the major activity observed. Deer grazed more and rested less in summer than during winter. Copulations may occur primarily at night. Home ranges of bucks were 1arger than those of does, and home ranges of yearlings were larger than those of adults. Average home range size of the Columbian white-tailed deer was smaller than that reported for other subspecies. Deer avoided close association with cattle and used those areas where cattle densities were lowest or where cattle were not present. Deer showed preference for improved pasture prior to introduction of cattle for seasonal grazing.

Book White tailed Deer Habitat Use Movements and Reproduction at Barksdale Air Force Base Louisiana

Download or read book White tailed Deer Habitat Use Movements and Reproduction at Barksdale Air Force Base Louisiana written by Stephanie Kathryn Hasapes and published by . This book was released on 2012 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite decades of widespread interest and extensive research, many questions remain about white-tailed deer (Odocoileus virginianus) seasonal movements and habitat use in the southeastern United States. Certain seasons, like parturition and breeding, have been studied in detail; however, there is a general lack of specific, year-round information on herd dynamics. The availability of GPS-based telemetry has made studies of year-round movements feasible, and there has been a recent increase in data of this type. During 2009-2011, I assessed deer habitat use and movement dynamics in Northwest Louisiana. Barksdale Air Force base consists of 8,900 ha of bottomland hardwood and upland managed pine stands in Bossier Parish, LA. I placed GPS radiocollars on 15 adult male and 15 adult female white-tailed deer and obtained 1 fix per hour for approximately one year. I quantified annual and monthly home range sizes and habitat composition, and seasonal movement parameters for adult white-tailed deer. Adult home range and core area sizes were larger during the winter months than the summer months for both genders. Male monthly home ranges varied from 97 to 380 ha and were larger than female home ranges (44-181 ha; P 0.0001) in all months. Habitats were utilized similarly by males and females. Shrub habitats and hardwood bottoms were utilized more than expected throughout the year while thinned and wet hardwood bottoms and scrub habitats showed little utilization. Openings such as fields, food plots, and developed areas were preferred when present as patches in primarily forested areas but were avoided when found as large uninterrupted tracts of land. All other habitat types were similar in preference (P 0.05) and showed little variation among months. Overall, males moved more than females for daily movement rate and extreme daily distance. Movement peaked for both genders in the winter season around breeding. I found that movement rates and patterns differed greatly between years, perhaps more than variation among seasons. Ten out of 14 female deer made breeding season excursions outside of normal movements, presumably to seek additional mating opportunities. Although movements declined around the predicted date of parturition, I did not find that movements in the weeks surrounding known parturition dates differed from pre- or post-parturition based on vaginal implant transmitter expulsion dates (P > 0.0664). I also quantified fawn survival, home range size, and habitat composition up to three months of age. Overall fawn mortality was 50%, which is generally consistent with other studies in the southeast. I observed differences in fawn mortality between different habitats on base, with 5 of 6 fawns predated before 30 days on the hardwood-dominated western half and 1 of 6 fawns dying (from apparent internal trauma and subsequent starvation) before 30 days on the pine-dominated eastern half. Fawns in the hardwood ecotype had larger home ranges (P = 0.0011) and core areas (P = 0.0018) than the pine ecotype but doe home ranges and core areas did not differ by ecotype (P > 0.2578). Known parturition sites were closer to habitat edges (P = 0.0242) and developed areas (P = 0.0476) than random sites within doe home ranges, suggesting does were seeking areas of their home range with more cover at parturition. The majority of fawns utilized habitats differently than their dams, with fawns being located more often in developed areas and mixed stands and does being located more often in mature pine stands and shrub habitats. Movement and home range data suggest white-tailed deer at Barksdale are finding adequate year-round resources to meet their needs. Fawn survival appeared to vary considerably depending on habitat at the base, and the provision of additional fawning cover in the form of small openings or timber harvests in areas of mature forest may aid in survival. Female movement data and summer habitat use data raise the possibility that deer density is below target density for harvest management at the site. An accurate estimate of density should be obtained and it may be advisable to consider changes to harvest regulations to increase herd density.
