In another paper, Paleoecology and inter-situ restoration on Kauai, Hawaii, David Burney (National Tropical Botanical Garden, Hawaii) and Lida Pigott Burney (Makauwahi Cave Reserve, Kalaheo) examine human-caused extinctions on the Hawaiian island of Kauai. Paleoecological studies from around the world show the devastating effects of human colonization on islands. Island histories reveal that hunting and landscape changes caused by humans each play a key role, but many of the extinctions seen on islands are probably from introduced predators, herbivores, plants, and diseases. On the island of Kauai, conventional conservation tactics focus on both restoring organisms in the wild as well as using zoos, botanical gardens and genetic banks. However, these tactics arent working well. The authors propose that conservationists try inter-situ conservation - the establishment of species by reintroduction to locations outside the current range but within the recent past range of the species. This method could provide a hedge against extinction.
Another paper in the Special Issue, Paleoecology and ecosystem restoration: case studies from Chesapeake Bay and the Florida Everglades, by Debra Willard and Thomas Cronin (US Geological Survey), focused on using paleoecology as a restoration tool. John Williams (University of Wisconsin, Madison) and Steve Jackson (University of Wyoming, Laramie) created a simulation of future climates and ecological responses based on the Intergovernmental Panel on Climate Changes emission scenarios in the year 2100 in their paper, Novel climates, no-analog communities, and ecological surprises. Daniel Gavin (University of Oregon, Eugene) and colleagues looked at charcoal records from lake sediments and soil profiles in Forest
