Impacts on Other Natural Areas

Q27. On page 15 of your written testimony you state the following:

“Other Natural Areas: Natural ecosystems are highly vulnerable to degradation from climate change. Federally protected natural areas have become a repository for the Nation's rarest species and are critical for the conservation of biological diversity. The composition, geographic distribution, and productivity of many ecosystems will shift as individual species respond to changes in climate. These will likely lead to reduction in biological diversity and in the goods and services ecosystems provide for society, such as clean water and recreation. Freshwater wetlands are

particularly at risk from climate change. IPCC findings show that:

[ocr errors]

Precipitation changes and salt water intrusion from sea level rise could adversely affect the ecological communities of the Florida Everglades and degrade the habitat for many species of wading birds.

• The wetlands of the prairie pothole region of North America, which support half the waterfowl population of this continent, could diminish in area and change dramatically in character in response to climate change, significantly exacerbating the destruction already caused by agriculture."

Please document these statements.

A27. Two chapters of the document Climate Change 1995 – Impacts, Adaptations and Mitigation of Climate Change: Scientific-Technical Analyses summarize the IPCC's most recent findings on impacts on and adaptations for non-tidal wetlands (Chapter 6) and coastal zones and small islands (Chapter 9) in a changing climate. Copies of these chapters are attached.
