The Natural World of Coll

I am not a biologist, geologist or any other type of natural world-ist. This section shows photo essays of just some of Coll's offerings which, I hope, you will enjoy. Please don't hesitate to contact me if you spot any errors.


It's the location of Coll, it's isolation, the minimal inhabitance and a sympathetic community that all add up in maintaining Coll's rich natural environment. Coll has many diverse habitats and this alone contributes to the unique variety of common and unusual species found here. The list of Coll rarities is quite special and this attracts many to Coll to study, or just experience, the thrill of a find.
