Primary Succession on Mount St. Helens: Rates, Determinism, and Alternative States
Abstract
We explored vegetation recovery on primary surfaces after the 1980 eruption including whether different communities might exist under similar conditions. Data were from repeat sampling of permanent plots, grids and depressions that formed during the eruption (potholes). We assessed succession rates using turnover, community similarity and trajectory complexity. We estimated turnover from community type change, while information theory described trajectory complexity. Similarity between repeat samples assessed succession rate. Succession vectors defined by detrended correspondence analysis (DCA) of repeatedly measured plots assessed floristic change. We determined the degree to which habitat variables predicted species composition using redundancy analysis. We tested the hypothesis that only one CT could occupy a particular habitat type (HT) by comparing species composition within CTs and HTs.
Successional rates declined with increasing elevation, proximity to colonists accelerated succession and succession may be arrested when strong dominants establish quickly. Biotic effects from Lupinus strongly alter successional rates by changing the rules for subsequent invasion. Environmental stress affects seedling establishment (drought) and biomass accumulation (infertility).
We explored the effects of determinant factors. The correspondence between vegetation and predictive factors was initially weak, but sometimes increased, limited by stochastic, transient and contingent effects. Contingent events also limited floristic convergence. Dispersal limitations and priority effects may have limited potential convergence. Unexplained variance in studies of plant to environment relations is largely due to contingent events, unmeasured variables and suboptimal statistical models.
We conducted a search for alternative states. While multiple communities may exist in some habitats, these may converge. Where indications that alternative states exist, more detailed habitat analysis may reveal differences that support alternative communities. Our data suggests that often there is a reasonable correlation between a community and a habitat, thus supporting the single state hypothesis. This long term study on Mount St. Helens provided significant insights into ecosystem recovery processes and has improved restoration methods.
