Welcome to the website of the New Jersey Division of the Allegheny Society of American Foresters. We hope that our members and others who are interested in ecology and conservation issues find this a useful and reliable source of up-to-date information on forest-related issues.
by Michael Gallagher, Science & Technology committee Monitoring fire effects is important for evaluating ecological outcomes of fire management efforts and refining silvicultural methods for maintaining and restoring healthy forests. While monitoring fire effects is conceptually straightforward (i.e. making observations of change due to fire), selecting the indicators of ecological change and measuring them at appropriate spatial and temporal scales is difficult and time consuming to the extent that such monitoring is rarely conducted. However, new indices for rapidly assessing burn severity are helping managers and ecologists improve their fire monitoring. The term fire effects describes the collection of direct and indirect ecological impacts of wildland fire (e.g. prescribed fire or wild fire). Direct fire effects, known as first order fire effects, are those that occur during a fire event as a direct result of the chemical and physical processes of fire, such as the consumption of biomass, the girdling [...]
Habitat managed using the species-specific, science-based guidelines for golden-winged warblers on Sparta Mountain WMA (in its 4th growing season). photo by Sharon Petzinger by Sharon Petzinger, NJDEP Division of Fish & Wildlife During 2012–2014, researchers studied the success of breeding Golden-winged Warblers in habitats of the eastern U.S. managed using Working Lands for Wildlife conservation practices. An article titled “An Evaluation and Comparison of Conservation Guidelines for an At-risk Migratory Songbird” represents an accruement of evidence supporting the notion that managed upland habitats (particularly timber harvest, old field management, and grazing management) host consistently high levels of Golden-winged Warbler nesting success and fledgling productivity. Researchers evaluated five Natural Resources Conservation Service (NRCS) ‘‘management scenarios’’ with respect to nesting success and vegetation conditions: grazing management, timber harvest, old field management, prescribed fire-old field, and prescribed fire-young forest. Each study site had recently been created or maintained using one of [...]
by Sharon Petzinger, NJDEP Division of Fish & Wildlife A golden-winged warbler found to be breeding in New Jersey. photo by David Kenny A series of research articles on Golden-winged Warblers were published in the book "Golden-winged Warbler Ecology, Conservation, and Habitat Management". The fourteen chapters in this book range from the distribution and status of the Golden-winged Warbler throughout its breeding and wintering range to research on the breeding grounds (habitat use, fledgling survival, nest site selection, hybridization) to wintering and migratory stopover habitat, and finishes with a synthesis of the new research and future directions. The chapter titled "Space and Habitat Use of Breeding Golden-winged Warblers in the Central Appalachian Mountains" analyzed breeding territories of individual male Golden-winged Warblers -- which is the area the male actively defends -- and also tracked them with radio telemetry to find and analyze their home ranges. Male Golden-winged Warblers moved >660 [...]
Congratulations to SAF forester Bob Williams for sharing a featured article with Bill Haines, Jr. in the Spring 2017 edition of Rutgers Magazine. The two discuss cranberries, the clean water that comes from the forest that is needed for cranberries, and the proper stewardship needed to perpetuate the forest while benefiting wildlife.
