Ecological Succession Another important concept related to biomes
... Ecological succession is the non-seasonal change in the types of plant species that occupy a given area through time. It progresses through stages from bare rock to a climax community. Succession is easiest to understand by using a generalized forest as an example. The next few slides will show you ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
