Conservation ecologists look into habitat losses

Narrator:        This is Science Today. As habitat losses continue to rise, wildlife experts are looking to maintain landscape corridors, or strips of land that connect separated areas of similar habitat. Mark Schwartz, a conservation ecologist at the University of California, Davis says there are consequences when habitats are lost.

Schwartz:        Our remnant habitats where are animals survive are fragmented and often disconnected from one another and we need to have that connectivity between those animals for viable, sustainable populations. We still don't understand how often, for example bears might need to move back and forth between patches in order to maintain healthy populations of those bears.

Narrator:        Schwartz says having more knowledge of the ecology of the species is key to managing their habitats.

Schwartz:        Now we're thinking about species not moving seasonally or intergenerationally but over a period of time for centuries. Corridors in this sense is a really thinking about a string of reserves that are allow for that natural shift of distribution of species as we see climate change in the future.
