Help! Adding Shapefiles (polygons) together to increasing values?!

Hi All!

Could use some help. I have a bunch of species distributions of parrot species all over Indonesia. I'm trying to add them together to create one shapefile. However, I need to keep density information.

For instance, if 3 polygons overlapped in one area, I somehow need a value of 3 where they overlap. I have 77 species.

What is the best way to do this? I need to add polygons together, but have the output shapefile represent areas the area with high species overlap differently then areas with low species overlap. Any ideas?

Thanks
Adam
