Lichen abundance and biodiversity along a chronosequence from young managed stands to ancient forest, 1993

The diversity of epiphytic lichens in old growth forests has stimulated considerable research (e.g., Howe 1978, Pike et al. 1975; Hoffman and Kazmierski 1969). We possess few data on the lichen communities of younger stands or the manner in which they develop as the forest ages. As our society grapples with the consequences of habitat loss and pressure on existing natural populations, such data are acutely needed (FEMAT 1993). This paper seeks to describe the relationship between forest age and the abundance and diversity of lichens in one region, and in doing so, to invite more rigorous assessment of the conservation needs of lichens with respect to forest management. Moveover, that documenting these patterns will facilitate research into age- related processes directly influencing lichen abundance and diversity.
