Carabid beetles were collected by means of pitfall trapping in four forest successional
stages: 1) Regeneration (3-8 years); 2) Immature (25-45 years); 3) Mature (65-85 years); and
4) Old-Growth (>200 years). The study was conducted at two locations, Victoria Watershed
South, and Koksilah, in Coastal Douglas-fir forests on Vancouver Island. A total of 28
species was collected during the year of collecting. Intraspecific comparisons were made
and six distributional patterns were identified. These are: 1) Regeneration specialists; 2)
Generalists; 3) Forest species; 4) Recovering species; 5) Old-Growth specialists; 6)
Unexpected pattern. A corrected species richness measure was calculated and showed the
regeneration sites to have the greatest species richness. There was no replicated, significant
difference among the other three stages. Other diversity measures are discussed, as are
implications for the forest industry.
