Fig. 2. Cumulative mortality percentages of the seedlings of (a) Betula pubescens and (b) Pinus sylvestris and cuttings of (c) Arctostaphylos uva-ursi and (d) Empetrum nigrum. The death rate of the transplants was recorded every spring and autumn from 1996 through 2005. The first inventory was performed in autumn 1996. The curves have been calculated separately for mulch-covered (n = 3) and uncovered (n = 3) plots.
