More Info<\/strong><\/p>\n

It’s a fundamental tenet of ecology that “natural disturbances” such as wind, fire and pest\/disease outbreaks play a major role in structuring plant communities and hence whole ecosystems.<\/p>\n

A disturbance occurs, setting a plant community back to an early successional stage; it then goes though a sequence of stages until again disrupted.<\/p>\n

In general, the species composition and relative abundance within plant communities\u00a0 is determined in large part by the types of natural disturbance that are most prominent.\u00a0 So for example forest stands that are subject to repeated fire as the major disturbance, e.g. as in the boreal forest, are likely to differ in species composition from forests that are subject to repeated wind as the major disturbance, as in NS.<\/p>\n
