3.1. 2005–2006 Treatment effects
In 2005–2006, 53 species were detected on 50-m radius point
count surveys. Nineteen species occurred in >30% of stands
in at least one year (Table 1).
Species richness and Shannon diversity valueswere lowest
in old clearcut and two-age harvests, but not significantly after
Bonferroni sequential adjustment of alpha levels (Table 1).
Mean species diversity in clearcuts was greater than two-age
stands, but the trend was not significant.
