英文摘要 | Epixylic (log-dwelling) flora contribute much to forest biodiversity, but have been shown to decline with intensive management, perhaps through the reduced supply of coarse woody debris, their preferred substrate, and the altered mesoclimate of the understory. Such declines might be ameliorated through modifying the plantation management practices. This study examined the response of epixylic flora to commercial thinning treatments in 6 mid-rotation conifer plantations of northwestern New Brunswick, Canada. Treatments included an unthinned control, and thinning with: moderate debris, moderate debris with added snags, or no-debris. Epixylic flora were surveyed in the fast and third year after thinning, on 30 logs in each of the 4 treatments, using both 10 x 20 cm quadrats (%-cover) and a presence-absence census of whole-logs. Treatments were evaluated at log and stand scales, based on the putative disturbance-sensitivity of different epixylic functional groups. Analyses included indicator species analysis, ANOVA of functional group richness and cover, NMS ordination, and PERMANOVA. Thinning with no-debris or moderate-debris reduced species richness at the stand scale, and increased cover at the log-scale. Composition shifted towards chlorolichens, vascular plants, and forest floor or asexually-reproducing bryophytes in thinned treatments, whereas liverworts and bryophytes with desiccation-sensitivity or those lacking asexual reproduction showed slight declines; most bryophyte groups showed no change. Moderate debris with snags and unthinned treatments showed the fewest compositional differences, and maintained many of the same sensitive groups, but all thinned treatments showed similar trajectories of compositional change. Additional monitoring is required to determine whether thinning with moderate debris and snags offers effective conservation of epixylic species, but debris removal (e.g., for biomass harvest) should be discouraged. |
