Meilleur, A., Bouchard, A., Bergeron, Y. (1992) The use of understory species as indicators of landform ecosystem type in heavily disturbed forest: an evaluation in the Haut-Saint- Laurent, Quebec. Vegetatio, 102(1):13-32.

Résumé

Analysis to obtain the ecological groups are based on the links of herbaceous plants and shrubs. This approach is defined as a sociological one where grouping is based only on the species' affinity, and 56 ecological groups were obtained. These groups were then characterized according to abiotic variables, especially geomorphological data: 39 of the 56 groups were significantly associated specifically with one of 10 morphogenic features, while 13 of these groups were associated with two or three features. The ecological groups associated with one specific geomorphological process showed a strong link to one texture and one specific drainage class. Groups associated with several features were linked with one drainage class, usually imperfect, and a certain topographic situation. Ecological groups showing a strong association to more than one feature can be of cartographic use, provided soil texture is analysed to determine the origin of the deposit. The type of deposit becomes non determinant on vegetation where drainage and topographic variables indicate (very) poorly drained sites. -from Authors
