climax theory

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

A theory that embraces the idea of successional development to an optimum sustainable vegetation community that is in equilibrium with its environment. Two conceptual models of climax...

climax vegetation

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

If a bare surface becomes available for colonization by plants, the vegetation will pass through a succession of so-called seral stages as more complex communities replace the earlier,...

community

Overview page. Subjects: Biological Sciences — Earth Sciences and Geography.

Generally, any grouping of populations of different organisms that are found living together in a particular environment; essentially, the biotic component of an ecosystem. The organisms...

consocies

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

A little used term, derived from the Clementsian scheme for vegetation classification, that refers to a seral community in the succession to a climax community with consociation status. See...

diversity

Overview page. Subjects: Biological Sciences.

The species-richness of a community or area. The concept provides a more useful measure of community characteristics when it is combined with an assessment of the relative abundance of...

fire climax

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

(pyroclimax)

Overview page. Subjects: Environmental Science.

An area of land that is capable of supporting a particular climax plant association.

native pasture

Overview page. Subjects: Environmental Science.

Land that is used for grazing, on which the climax plant community is forest, but which is used and managed primarily to produce native or naturalized plants for forage.

plagioclimax

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

A term that is almost synonymous with biotic climax, although they are sometimes given different meanings. Generally, both refer to a stable vegetation community arising from a succession...

range condition

Overview page. Subjects: Environmental Science.

The status of the vegetation and soil of a particular area of rangeland, compared with the natural potential (climax) for that site.

retrogression

Overview page. Subjects: Plant Sciences and Forestry — Ecology and Conservation.

A successional change, usually from an existing climax community, leading to a less diverse and less structurally complex community. The change frequently involves a reduction in biomass....

secondary succession

Overview page. Subjects: Biological Sciences — Environmental Science.

The re‐establishment of vegetation on land that has had a vegetation cover at some time in the past but which might have been destroyed by natural processes (including lightning fires,...

seral stage

Overview page. Subjects: Biological Sciences — Environmental Science.

A phase in the sequential development of a climax community. See succession.

sere

Overview page. Subjects: Biological Sciences.
