Résumé

Forest decline can be the result of multiple stresses such as air pollution or natural processes. This phenomenon can directly affect trees as well as the fauna and nonarborescent flora within these ecosystems. From 1987 to 1989 we studied insectivorous bird, arthropod, and plant populations in 18 sugar maple (Acer saccharum Marsh.) stands affected by decline in southern Quebec. On average, there was a 20-30% foliage loss. Mean number of bird species and pairs per plot were negatively correlated with decline index (P = 0.08 and P = 0.09), mostly as a result of negative trends obtained for canopy snatchers and canopy- and shrub-foliage gleaners. Conversely, insect herbivores sampled in the canopy and on saplings as well as ground foragers were not correlated with decline index. Our data do not allow us to easily conclude that contemporary maple decline alone can lead to drastic changes in bird and insect communities. However, the data do not rule out the possibility that subtle changes could be occurring in the wildlife communities in sugar maple forests in southern Quebec.
