Bird Abundance and Distribution in Managed and Old-growth Forest in Maine
By John M. Hagan and Stacie L. Grove

This report summarizes 4 years of bird surveys in Maine's industrial forest.  Habitats are divided into early-successional even-age forest, partial cut forest, mature forest, and old-growth forest.  Data were collected in two landscapes, one dominated by clearcutting, and the other dominated by partial cutting.  Birds are separated into categories based on which harvest type and forest age the were most frequently encountered.

The Early Development of Forest Fragmentation Effects on Birds. 1996.

We developed a conceptual and mathematical model of the temporal effects of forest fragmentation on bird populations. We provide support for the model using abundance data for several forest bird species and reproductive success data for the Ovenbird (Seiurus aurocapillius), collected in an industrial forest landscape in northcentral Maine.

Clearcutting in Maine: Would Somebody Please Ask the Right Question? 1996.

Maine has been embroiled in considerable debate over the Green Party initiated referendum on forest practices in Maine. Better known as the clearcutting referendum, its supporters and opponents have staked out their terms in what has become the bitter debate over "jobs for Maine people" versus the "future of the North Maine Woods."

Amidst the deluge of media campaigns and ideologic predictions, rest important questions about forest management practices and how best to ensure a viable future for the people and forests of Maine. In this document, John Hagan contributes a perspective to this debate.

1995 Report: Selection Cutting, Old-Growth, Birds, and Forest Structure in Maine. 1996.

This report contains an overview of results from a study begun in 1995 to examine the effects of partial cutting on forest structure and birds. The study was initiated to provide the public with better information on which to formulate forest policy in Maine.

In this study we surveyed birds and numerous structural characteristics of forests under several different partial cutting conditions, as well as in virgin forest.

Diversity and Abundance of Landbirds in a Northeastern Industrial Forest. 1997.

This report documents how landbird species use an industrial forest landscape in northern Maine. We relate diversity and abundance of landbird species to habitat types, ranging from recent clearcuts to mature hardwood and softwood forests of Maine. We also relate species abundance to landscape level parameters, such as the amount of early successional forest within a 1-km radius of the sampling location. Based on habitat changes in a portion of Maine's industrial forest over the last decade, we estimate how bird species' abundances might have changed. And finally, we compare our estimates of species changes with population trends derived from the U.S. Fish and Wildlife Service Breeding Bird Survey (BBS) data for the state of Maine.

Harvest Rate, Configuration, and Forest Fragmentation: A Simulation of the 1989 Maine Forest Practices Act. 1997.

This report contains the results of modeling which simulated the effects of five clearcutting regimes at various annual harvest rates ranging from 1.00% to 2.5% on the configuration and amount of mature forest in a hypothetical township (6 x 6 mi) in Maine. Employed in the modeling were all the buffer and separation zone restrictions on clearcutting as dictated by the 1989 Maine Forest Practices Act (MFPA).

Coarse Woody Debris: Humans and Nature Competing for Trees. 

Foresters have long fought the agents of tree mortality. Managing for dead wood, however, may be essential to meeting the biogiversity goals of sustainable forestry. Listed guidelines can help foresters find a balance.

John Hagan and Stacie L. Grove. Journal of Forestry, January 1999, Vol. 97. No. 1, pages 6-11.
