PRINCIPLE 2: MAINTAINING HABITAT IS FUNDATO CONSERVING SPECIES.
A species habitat is the ecosystem conditions th
its life requirements. Our understanding of habitat isour knowledge of a species ecology and how that dwhere a species is known to occur or likely to occur. H
be considered at a range of spatial and temporal sinclude specific microsites (e.g., occupied byinvertebrates, bryophytes, some lichens), large hetehabitats, or occupancy of habitat during certain tim(e.g., breeding sites, winter range areas).

PRINCIPLE 3: LARGE AREAS USUALLY CONTAISPECIES THAN SMALLER AREAS WITH SIMILAR H
The theory of island biogeography illustrates a basic that large areas usually contain more species than smaller arsimilar habitat because they can support larger and mor
populations. The theory holds that the number of specieisland is determined by two factors: the distance from the m
and island size.

PRINCIPLE 6: CLIMATE INFLUENCES TERRESTFRESHWATER AND MARINE ECOSYSTEMS
Climate is usually defined as all of the state
atmosphere seen at a place over many years. has a dominant effect on biodiversity as it infmeteorological variables like temperature, preciand wind with consequences for many ecologicphysical processes, such as photosynthesis abehavior. For example, major temperature fluctua
surface waters in the Pacific Ocean due to climatic events can influence weather and signwarm temperatures throughout much of B.C. Thiscan increase some wildlife populations or impamigration timing of some migratory bird population
