Herpetofauna Response to Fire and Imazapyr in Intensively- managed Mid-rotation Pine Stands in Mississippi

Forest managers are increasingly expected to incorporate conservation of biodiversity in forest management plans, but a paucity of information exists regarding herpetofauna responses to mid-rotation release practices of dormant-season prescribed fire and herbicide in intensively-managed pine (Pinus spp.) stands. However, these management tools have demonstrated capabilities of improving conservation value in southeastern pine forests. Therefore, we investigated herpetofauna responses to factorial combinations of dormant-season prescribed fire and imazapyr using a randomized complete...

Biodiversity Response to Fire and Herbicide in Intensively-managed Pine Stands of Mississippi

Common mid-rotation forest management practices in intensively-managed pine (Pinus spp.) stands include thinning, fertilization, herbicide use, and prescribed burning. However, greater herbicide use and less prescribed fire have generated questions regarding treatment effects on biological diversity within these systems. Therefore, we determined biodiversity response (songbirds, rodents, reptiles, amphibians, carabid beetles, understory vegetation) to factorial combinations of dormant season prescribed fire and imazapyr herbicide in thinned and fertilized, mid-rotation intensively...

Prescribed Fire Behavior in Mid-rotation Pine Stands of Mississippi

Fire's stochastic behavior caused by vegetation, topography, and weather has caused concern and reduced use among landowners and managers. To better understand fire behavior in fire-absent forest stands, we examined fire characteristics relative to vegetation conditions manipulated with or without a prior herbicide application. We used six replicate stands with four randomly-assigned treatment plots (burn, herbicide, burn*herbicide, control) to assess dormant season burns with a three-year fire return interval. We measured fuel moisture and weather variables pre-burn, residence time, rate...

The Natural Resource Enterprises Program at Mississippi State University

Previous research conducted at Mississippi State University found that non-industrial private (NIP) landowners in Mississippi can diversify incomes derived from their properties through the development of fee hunting enterprises. In 1998, revenues collected from fee hunting on Mississippi private lands ranged from US$2,964 to $5,254 on average per landowner or $7.50 to $14.28 per ha, depending upon the region. Net revenues averaged from $1,539 to $3,244 per landowner survey respondent or $3.90 to $9.54 per ha. Additionally, fee access wildlife recreation contributed an average increase of...

Survival and Cause-specific Mortality of Adult Male White-tailed Deer Managed Under the Quality Deer Management Paradigm

Quality deer management (QDM) advocates the protection of younger-age white-tailed deer (Odocoileus virginianus) bucks, but the subsequent survival of these animals remains unknown. We conducted a study to investigate the impact and importance of harvest and non-harvest mortality factors on adult male white-tailed deer in Mississippi on areas managed under QDM. We captured 408 deer and fitted 238 adult bucks with radio collars from February 1990 until January 1997. During the study, we documented 185 mortalities, which were used to estimate survival and cause-specific mortality rates....

Natural Resource Enterprises Educational Center in Mississippi: A Tangible Wildlife Management Tool Available for Mississippi Private Landowners

Over 1 million people participated in wildlife-associated recreation in 2001 in Mississippi, spending a total of US $974 million. Research conducted at Mississippi State University (MSU) documented net revenues averaging from $1,539 to $3,244 (varied regionally) per landowner in 1998 for Mississippi non-industrial private landowners operating fee-hunting enterprises. Habitat management activities associated with fee access wildlife recreational enterprises benefit wildlife when integrated with existing land management activities. MSU research documented that bird species richness and...

Integration of Natural Resource Enterprises and the Economic Potential for Ames Plantation

Expenditures by hunters, anglers, and wildlife enthusiasts represent an important segment of income potential to most rural economies from natural resource-related activity. Research conducted at Mississippi State University (MSU) found that non-industrial private (NIP) landowners in Mississippi could diversify incomes derived from their properties through the development of fee hunting enterprises. In 1998, revenues collected from fee hunting on Mississippi private lands ranged from US$2,964 to $5,254 on average per landowner or $7.50 to $14.28 per ha while net revenues averaged from $1,...

Food Availability Versus Preference of Wild Turkey Poults in Intensively-managed Pine Stands in Mississippi

Importance of invertebrates to growth and development of eastern wild turkey (Meleagris gallopavo silvestris) poults has been well documented. However, few studies have investigated direct invertebrate use by poults, specifically in relation to alternative forest management regimes. Therefore, we measured invertebrate selection by turkey poults in thinned, mid-rotation loblolly pine (Pinus taeda) plantations, treated with factorial combinations of prescribed burning and a selective herbicide, in east-central Mississippi in 2000 and 2001. Using suction sampling and humanimprinted turkey...

Relationships Between Landscape Characteristics and Space Use of Raccoons in Two Managed Pine Forests

Raccoons (Procyon lotor) are ecological generalists that use a variety of landscape and habitat types. Although space and habitat use are well understood for raccoons throughout the southeastern United States, relationships between space use and landscape characteristics are not. We examined relationships between space use and landscape characteristics for 95 radio-marked raccoons monitored during 1996-1997 on two adjacent forested landscapes that differed in forest management strategies. We noted relationships between space use and patch richness, proportion and size of riparian habitats...
