Nature photographers on this list might be interested in The Nature Conservancy's Digital Photography Contest. They are soliciting stunning images of nature, including lands, waters, plants, animals or people. The contest runs until the end of September 2009. All contest info is here: http://www.nature.org/photo .
Watch out. It's a rights grab:
"By entering the contest, you hereby grant to The Nature Conservancy (i) a nonexclusive, worldwide, irrevocable, royalty-free license to reproduce, distribute, publicly display and publicly perform the photographs you submit to The Nature Conservancy, and (ii) the right to use your name, city, state and country of residence in promotions and other publications."
