Biodiversity is a new term with profound ramifications: all things are connected in a web of life. Any action taken in an ecosystem affects all the components of that ecosystem.
Conventional wildlife management failed to protect species and habitats in wilderness areas. A new approach to conservation biology is based on the interconnectivity of ecosystems.
The video workshop BIODIVERSITY: THE VARIETY OF LIFE, through the use of maps, diagrams and examples, introduces several new terms and concepts, including fragmentation, linkage, and viable population, which offer important insight into preserving the balance of dynamic ecosystems. While focusing on the North Cascades ecosystem, it presents concepts which apply everywhere.
The DVD version of this program is recorded on DVD-R which is not compatible with some older DVD players. See the new DVD page for more details.
