Resin Flow In Loblolly And Shortleaf Pines Used By Red-Cockaded Woodpeckers, David L. Kulhavy, W G. Ross, J H. Sun, Daniel Unger, I-Kuai Hung, Richard N. Conner

We measured resin flow in loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pines in stands used by red-cockaded woodpecker, Picoides borealis (Vieillot), in the Angelina and Davy Crockett National Forests in eastern Texas. We also measured resin flow in a mature loblolly pine stand not used by the woodpeckers. Resin flow varied by study area, species, and stand position. In woodpecker stands, pines experiencing low levels of competition seemed better able to tolerate the continual resin drainage associated with red-cockaded woodpecker resin well pecking. In the Angelina National Forest, all new cavity trees excavated during the study were …
Red-Cockaded Woodpecker Cavity Tree Damage By Hurricane Rita: An Evaluation Of Contributing Factors, Ben Bainbridge, Kristen A. Baum, Daniel Saenz, Cory K. Adams
Red-Cockaded Woodpecker Cavity Tree Damage By Hurricane Rita: An Evaluation Of Contributing Factors, Ben Bainbridge, Kristen A. Baum, Daniel Saenz, Cory K. Adams

Picoides borealis (Red-cockaded Woodpecker) is an endangered species inhabiting pine savannas of the southeastern United States. Because the intensity of hurricanes striking the southeastern United States is likely to increase as global temperatures rise, it is important to identify factors contributing to hurricane damage to Red-cockaded Woodpecker cavity-trees. Our objectives were to examine the effects of landscape-level factors on wind damage to cavity-trees and assess the relative risk of wind damage for different tree species and trees with different types of cavities. We evaluated wind damage to cavity-trees from Hurricane Rita on the Angelina, Sabine, and Davy Crockett national forests …

Biological Status Of Leatherside Chub: A Framework For Conservation Of Western Freshwater Fishes, Mark C. Belk, Jerald B. Johnson
Biological Status Of Leatherside Chub: A Framework For Conservation Of Western Freshwater Fishes, Mark C. Belk, Jerald B. Johnson

Outside of anadromous salmonids and a few endangered species, biology of native freshwater fishes of western North America is poorly known. What do we need to know to effectively manage native species and avoid decline and extinction? A recent analysis of the role of science in the Pacific salmon controversy outlines a clear framework for biological evaluation and management of native species. This framework has three components: (1) determine status of populations based on genetic and ecological variation, (2) identify and quantify threats to populations, and (3) determine actions to alleviate threats and promote conservation of populations. We use our …

Experimental Reintroduction Of Red-Cockaded Woodpeckers, D. Craig Rudolph, Howard Kyle, Richard N. Conner
Experimental Reintroduction Of Red-Cockaded Woodpeckers, D. Craig Rudolph, Howard Kyle, Richard N. Conner
Faculty Publications
The Red-cockaded Woodpecker (Picoides borealis) is an endangered species endemic to the pine forests of the southeastern United States (Jackson 1971). Deforestation and habitat alteration have severely affected Red-cockaded Woodpecker populations; current populations are isolated and most are declining (Jackson 1971, Lennartz et al. 1983, Conner and Rudolph 1989, Costa and Escano 1989). The species has been extirpated from significant areas of suitable or potentially suitable habitat.
Southern Pine Beetle And Fire In Wilderness Areas: The Kisatchie Hills Wilderness, Kisatchie National Forest, David Kulhavy, William G. Ross
Southern Pine Beetle And Fire In Wilderness Areas: The Kisatchie Hills Wilderness, Kisatchie National Forest, David Kulhavy, William G. Ross
Faculty Publications
Southern pine beetle infestations affect wilderness areas in the southeastern United States. In the Kisatchie Hills Wilderness area in Louisiana, a southern pine 'beetle outbreak resulted in widespread destruction of longleaf pine. Nest trees of the red-cockaded woodpecker, an endangered species, also were killed. Following the epidemic, a fire fueled by beetle-killed pines went through the wilderness. Forest structure, species composition, successional processes and general ecosystem function were substantially altered as a result of these two related disturbances. Most wilderness areas containing southern pines were managed for pine timber before being designated as wilderness. Bark beetle outbreaks are a predictable …
