pioneer phase
pioneer phase
1. Generally, the ‘new plant’ stage of any cyclical pattern of vegetation change. In forestry, it is sometimes called the gap phase.
2. Specifically, a stage in the cyclical pattern of community change in heathlands, when individual Calluna vulgaris plants are young (up to 10 years old) and provide little cover, so there is maximum diversity of associated species. Although C. vulgarisbiomass is low, productivity in the new shoots is high. Compare building phase; degenerate phase; hollow phase; and mature phase.
