  1. Thin trees within forests: effects on non-vascular plants

    A replicated, site comparison study in 1994-1997 in boreal forest in Finland (Kuusinen & Siitonen 1998) found that thinning decreased the number epiphytic lichen species. The total number of epiphytic lichen species/ha was lower in early cut (69) than old growth (88) and similar to both treatments in late cut forest (78). Numbers of epiphytic lichen species/ha occurring on Norway spruce Picea abies was lower in early cut (47) than late cut and old growth forest (54-56). Data were collected in 15 sample plots (1 ha) classified according to the age of the dominant tree Norway spruce and recent signs of cutting, there were five replicates of the three treatments: early-cut (age 102 years, 465 cut stumps/ha), late-cut (age 135 years, 247 cut stumps/ha) and old-growth forest (age 161 years, 3 cut stumps/ha).
