Document Summary
Indicates measures of characteristics that can be used to assess the health and status of ecological communities and ecosystems. Communities with moderate levels of disturbance will have the highest species richness and diversity. The impact of disturbance is considered to be a factor of 3 variables: frequency type of disturbance. Ecological indicators can assess ecosyste(cid:373)"s health (cid:271)(cid:455) (cid:395)ua(cid:374)tif(cid:455)i(cid:374)g wate(cid:396) (cid:395)ualit(cid:455), biodiversity, and abundance of degradation of tolerant species. Species diversity measure of the variety and relative abundance of species present in an ecological community. Species richness total number of species in a community. Shannon index is used to quantify species diversity. To calculate p (proportion of species), divide the amount of certain species by the total amount of species in the habitat. Decrease the likelihood of the naturally occurring fire. Left to burn out on its own. Immediate intervention (fire extinguishing + removal of fuel) Area includes boreal forest, residences, oil preservations.
