Thanks Elf Shadow, i have actually never heard of that site before.

Clicks available for: South American Rain Forest, Reduce Pollution, Protect Endangered Species, United States Wilderness, Coastal Habitat

Clicks with extra steps available for: Plant Trees/Monarch Butterflies, Plant Trees/American Chestnut

A nice advantage i seen on Ecology Fund is that they emphasize that if you click on the sponsor links the donation is doubled.
