Effects of lichen ground cover on conifer growth in northern taiga

Cowles, S. (Sidney William) January 1984 (has links)
The effects of lichen ground cover (predominantly Cladina stellaris) on the growth of Picea mariana at Schefferville, Quebec and Pinus sylvestris at Kevo, Finland, was investigated in situ. Effect on seedling establishment was inferred through examining status quo conditions. While contiguous mat cover precluded establishment, its margins provided ameliorated conditions suitable for establishment. Moss covered areas were the most preferred sites. At Schefferville, ten perturbations involving fertilization, lichen removal, polyethylene overlays, and aqueous lichen extract application were effected on sixteen experimental plots. Branch elongation, needle nitrogen and bole diameter were statistically analyzed as functions of various monitored edaphic conditions. Leader elongation and needle nitrogen was measured at Kevo. Lichen presence over the term of both studies showed net beneficial effect on the trees; lichen extracts had significant detrimental effects. Seed germination was suppressed by lichen presence but enhanced by lichen induced low soil pH when in contact with the soil.
