To view the maps and satellite photos of the Earth on this page you will need Google Earth software. If you don't have Google Earth you can download it here.
It's free -- and it's fascinating. Using Google Earth you can zoom in on the BioGems, look at them from various perspectives, even rotate the Earth as you fly over them (who doesn't want that power?).
If you're not familiar with Google Earth, and with mapping programs in general, you may prefer to take this photo-and-video tour of the BioGems.

The boundaries of some BioGems, such as the Arctic National Wildlife Refuge or the Tongass National Forest, are set by government sources. In others, NRDC selected the boundary to offer a general view of the area on which our BioGems campaign focuses -- these boundaries are not exact.
