Pierre Drapeau

Dr. Pierre Drapeau obtained a Bachelor’s (1979), a Master’s (1982) and a PhD (1993) in Biological Sciences from the Université de Montréal. The subject of his thesis was bird community structure of the southern deciduous forest of Québec. From 1992 to 1994, he worked as a scientific coordinator for a program on ecosystem management of the Division of Regional Parks of the Montréal Urban Community. From 1994 to 1996, he did a postdoctoral training with the Interuniversity Research Group in forest Ecology (GREFi). He worked with collaborators of the GREfi on the issue of forest cover change in boreal forest and its effect on biodiversity using birds and small mammals as indicators. From 1996 to 1998, he coordinated many projects as an associate professor of the GREFi. He also participated in the demand for the Industrial Chair on Sustainable Forest Management, which was granted to both UQAM and UQAT in 1998. Since the creation of the Chair, Dr. Drapeau became a professor “sous-octroi” for the Department of Biological Sciences of the Université du Québec à Montréal. He is interested in wildlife-habitat relationships; effect of landscape structure on wildlife distribution, and on a more applied level; wildlife integration into forest ecosystem management.

Research orientation

Wildlife-habitat relationships in forest environment

Habitat characteristics are among the most important ecological factors responsible for the distribution of animal communities and species population in forest ecosystems. Our research aims at a better understanding of wildlife distribution inside different habitat components of the boreal forest mosaic. We study the relationship between local characteristics of habitat (stand type, vertical and horizontal vegetation structure, dead trees volume and density) and distribution of species, functional species groups and animal communities. Even though small mammals and insects are part of many projects, we concentrated on forest birds. Field work is done in naturally disturbed forests (fire and insect outbreak) as well as in managed forests.

Effects of landscape structure on wildlife distribution

This topic is related to the first one. It has become common knowledge that habitat use by wildlife isn’t based solely on local scale ecological factors. Composition and configuration of adjacent habitats can influence animal species abundance and presence (for a given set of habitat conditions). At a forest mosaic scale, landscape components are taken into account when evaluating cumulative effects of natural and anthropic disturbances on wildlife. Historically, boreal landscape has been modified on large areas by natural disturbance such as fire and insect outbreak. However, during the last few decades, industrial timber harvest became the dominant disturbance in many regions of the boreal forest. This study aims at evaluating how forest management differs from natural disturbance in terms of wildlife response to composition and configuration changes in the boreal forest mosaics. Field work is done in black spruce forest as well as in mixedwood forest. The study is done in collaboration with researchers of the Sustainable Forest Management Network, which brings together contributors from numerous Canadian universities.

Wildlife integration in forest ecosystem management

Traditionally, forest management was centered on one preoccupation: timber supply. Recent developments in terms of sustainable forest management – where all forest ecosystems components and uses has to be taken into consideration – lead to a significant change in forest practices. This research orientation emphasizes both the integration of knowledge on ecological factors responsible for wildlife distribution when managing forest areas and the planning of forest operations. The study aims at developing new approaches and tools that can be applied to managed forest areas and is based upon the principles and values of the Canadian Council of Forest Ministers on criteria and indicators for a sustainable forest management. Specifically, we wish to develop an ecological evaluation tool of species diversity in managed forest mosaics. This management tool will combine two knowledge units: a predicting unit of forest bird distribution in their habitat and a unit defining natural forest mosaic diversity inside forest areas. The integration of the two units will give a better picture of forest bird species diversity in natural forest mosaic, which is considered the mosaic of reference.
