Appropriate management of mid-rotation pine plantations can improve habitat for early successional and pine-grassland adapted avian species. I tested effects of Imazapyr selective herbicide and prescribed fire on plant and avian communities in thinned, mid-rotation pine stands contracted under the Conservation Reserve Program. Within 7 replicate sites, 2 8.1-ha plots were assigned either herbicide and prescribed fire treatment or control. I described components of vegetation structure and composition in 2006. I tested effects of herbicide and prescribed fire treatment on avian relative abundance, species richness, total avian conservation value, and density of select species during 2003 - 2006. Hardwood midstory decreased and grasses and forbs increased following treatment. A shift occurred in the bird community from closed-canopy forest to early successional and pine-grassland species. Treatment stands benefited many avian species exhibiting negative population trends.

This book was released on 2010. Effects of Prescribed Fire and Selective Herbicide (Imazapyr) on Biodiversity in Intensively Managed Pine Stands of Mississippi available in PDF, EPUB and Kindle. Prescribed fire and imazapyr are two silviculture tools used to control hardwood midstory competition in intensively managed, mid-rotation pine (Pinus spp.) stands but also may support conservation of biodiversity in the southeastern United States. Therefore, I investigated select measures of biodiversity response, small mammals, reptiles, amphibians, carabid beetles, songbirds, and vegetation communities, to fire and imazapyr treatments in intensively managed, mid-rotation pine stands of east-central Mississippi. I used a randomized complete block design of 6 stands (blocks) with 4, 10- ha treatment plots assigned randomly a treatment of burn only, herbicide only, burn + herbicide, or control. I applied dormant season prescribed fires every 3 years beginning in January 2000 and a one-time application of imazapyr in September 1999 using 877 ml/ha (12.0 liquid oz./ac; Arsenal®, BASF 2006). I sampled avifauna, herpetofauna, small mammal, and carabid beetle communities using appropriate sampling techniques for attaining species-specific relative abundance. I also measured vegetation structure and biomass. Vegetation and bird communities exhibited significant responses to treatments. Imazapyr had the greatest initial impact on communities followed by a long-term effect of repeated prescribed fires on a 3 year fire-return interval. Combining fire and imazapyr perpetuated high-quality browse for white-tailed deer (Odocoileus virginianus), plant species richness, high-priority bird species relative abundances, and diversity of landscape-level vegetation structure and biomass by creating a two-tier vegetation structure (pine canopy and herbaceous understory). Independent treatments also were more effective management approaches to sustain biodiversity than controls by maintaining or increasing overall species richness specifically soon after treatment application. Most responses of other wildlife communities were time-limited suggesting the possibility of greater effects of factors other than treatments such as long-term disturbance regimes (e.g., forest management practices, climate trends), proximity of treatment plots to wetlands, and landscape-level population dynamics including characteristics within and among stands. Combined and independent applications of these treatments will support biodiversity conservation, sustainable forestry objectives, and concomitant timber management goals. Long-term conservation of biodiversity within an intensive timber management matrix also may benefit from future investigations of multiple-herbicide tank mixtures, population dynamics of indicator species, and landscape-level biodiversity responses across multiple strata.

Effects of Prescribed Burning and Herbicide (imazapyr) on the Abundance and Diversity of Selected Invertebrate Communities in Thinned Pine Plantations of Mississippi available in PDF, EPUB and Kindle. Prescribed fire and herbicides are 2 silviculture tools used by forest managers to control hardwood competition in pine (Pinus spp.) forests. I tested effects of prescribed burning and herbicides on selected invertebrate communities, including carabid beetles, and compared 2 invertebrate sampling approaches in thinned, intensively managed pine stands in Kemper County, Mississippi. I used 6 replicate stands containing 4, 10-ha treatment plots each that were randomly assigned treatments of burn only, herbicide only, burn/herbicide, and control. I suction-sampled invertebrate communities and pitfall trapped carabid beetles to examine treatment responses. Direct effects of burning and overall vegetation response influenced communities most but responses were limited. Sampling inefficiencies may have obscured treatment effects and managers and researchers are advised to consider all available methods when integrating invertebrate research. Information on forest management effects is still lacking but future research incorporating invertebrate sampling will support a better understanding of management impacts on ecosystems.
