“…Nevertheless, the shift of the distributions of ramet size to larger values in the older stands (Fig. 1) suggested maturation of bilberry (Jonsdottir, Callaghan 1988). The positive relationships between stand and ramet age, as well as frequency of ramets with the age of 3-5 years, which show the fastest rejuvenation and highest gross productivity (Tolvanen 1995), decreased in the older stands (>201 years), supporting maturation of bilberry.…”

Responses to harvesting intensity in a clonal dwarf shrub, the bilberry (Vaccinium myrtillus L.)

et al. 1994

The effects of herbivory were simulated on stands of bilberry (Vaccinium myrtillus L.) in a boreal Empetrum-Myrtillus type forest. Five harvesting intensities were used (0 ?o (A), 25 ?o (B), 50 ?o (C), 100 ~o (D) of the bilberry ramets or all the ramets of all species (E)). Density and biomass of the stands, and growth of the ramets were monitored for five growth seasons, from 1986 to 1990. After damage new ramets emerged rapidly from dormant buds at the base of removed ramets. Between 70 and 97 ~o of the density relative to the control level was regained by the final harvest. However, only between 11 and 64?o of the biomass relative to the control level was recovered. Clipping reduced the branch growth, both in the new ramets and in the new parts of the old, unclipped ramets. Severe treatments (D and E) decreased the growth more than did light harvesting (B and C). Survival and fecundity of the ramets were not affected. The result therefore suggested that the bilberry is not able to recover totally from severe herbivory damage between the years of peak rodent population that shows a 3-4 year cycle. Nevertheless, extreme grazing pressure is rare in boreal ecosystems as alternative food is available for herbivores, and predators also limit the herbivore population. Hence the bilberry exhibits moderate tolerance of the usual level of herbivory damage.
