As soil quality and quantity improves, the life forms present in the area undergo a series of changes, each referred to as a seral stage.Eventually a stable climax community is formed.

Updates? The first inhabitants are lichens or plants—those that can survive in such an environment. Primary succession is the colonization of new sites/area by different species or communities of organisms. In summer, large expanses of Marsh Helleborine in flower provide a wonderful

Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage. One of the most unique places is the redwood forest, which can be found only in the fog banks along the coastal waterways of the northern part of the state. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. Certain species are capable of expressing characteristics indicative of the state of the ecosystem they occupy. Myosotis ramosissima.
These changes form a continuum between the two endpoints, with the actual stages being merely a fixed glance at the never-ending progression of plants and animals. This helps to hold a little water in the surface layers and
