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

Climate change and polar regions Climate change and wildlife

Temperatures will continue to rise

Frost-free season (and growing season) will lengthen
