Values of Biodiversity
• Biodiversity provides excellent conditions for and drives the processes that sustain species survival.
• Biodiversity provides for ecological, economic and cultural values to the world’s community.
• Climate change is changing species distribution through shifting habitat, changing life cycles, and development of new physical traits,

Values of Biodiversity
• People need ecosystems for adaptation and ecosystems need people.
• Biodiversity plays a major role in meeting human needs directly while maintaining the ecological processes upon which our survival depends.
• Biodiversity is a national asset and a powerful contributor to economic development, provision of natural resource, ecological processes, and improving human wellbeing.

Effect of Climate Change on Species: A case study
• Higher temperatures speed up reproductive cycles
• Fewer cold snaps that kill beetles. • Drought weakens trees, making
them more susceptible to beetles.• Dense older forests are more
susceptible to beetle outbreak.Mountain pine beetles are 1/8” to 1/3” long. Little insect – big impact.

‘‘Impact of climate change on biodiversity
• Species extinction 20-30% of species at risk. • Climate change and forests
Climate change and water

Temperatures will continue to rise
Frost-free season (and growing season) will lengthen
