Introduction

By Douglas C. Allen

Thanks to the effort and imagination of Dick Fox, I am pleased to have this collection of papers made available to forest landowners and other people with a broad interest in forest health.

These articles cover a range of topics, some general and others fairly specific. My purpose has been to touch on items that I sense are of current interest, to use the FOREST OWNER column as an opportunity for alerting New York forest owners of potential problems and, at times, to do nothing more than try and make a forest owner's walk through the woods a bit more interesting. In regard to the latter, I think it important for forest owners to appreciate that insects play many beneficial roles in forest communities and to realize that all insects which feed on trees are not necessarily "pests."

In order to be a good steward one must understand the biological components of a forest. Insects are but one of the diverse groups of organisms that interact to determine the character of a woodlot. Unfortunately, on occasion they compete with humans for resources of mutual interest. This is the point at which they are no longer mere curiosities but become pests. The best control measure is prevention. If we understand an insect and the manner in which it interacts with the forest well enough, we often are able to adjust our forest management activities accordingly. I hope these articles will stimulate readers to learn more about the entomological aspects of forest health.

Preface

By Richard J. Fox (past editor)

This project was commissioned by Michael Birmingham, Department of Environmental Conservation, in cooperation with Douglas Allen, Professor of Forest Entomology at the State University of New York, College of Environmental Science and Forestry.

The digitized printing of the photographs (primarily by Professor Allen) was accomplished using computer facilities at the NYS DEC offices in Cortland (HP ScanJet 2C; HP Laserjet 5P; 600dpi). The editor is grateful for the technical help of the Cortland Office professionals and their tolerance.

A special thanks is due Stephen Davison, Senior Forester and David Forness, Senior Forester of the NYS DEC Cortland Office, for a final proof of the reprints and helpful suggestions.

The 1997 Supplement is provided upon the request of Michael Birmingham and courtesy of Frank Dunstan, Director of the Division of Lands and Forests.
