Process of primary succession
WebbSuccession occurs in a series of stages. These include the primary colonisation by pioneer species, secondary colonisation, tertiary colonisation, shrubland and the climax community. Pioneer species have traits that allow them to colonise not hospitable land to life. These traits include being able to reproduce asexually and fix nitrogen. Webb21 jan. 1999 · A forest can develop in wet regions in less than 150 years. On Hawaiian lava flows, primary succession proceeds rapidly on wet windward slopes, but more slowly in dry areas. The influence of moisture can be seen on the Kona side, where the same flow can support a forest along the Belt Highway but be nearly barren near the dry coast.
