The heathland supports a typical invertebrate fauna, including a wide variety of butterfly species, and with spiders notably abundant. The site is regionally important for birds which favour heathland habitats.[2] References1. ^Black Down Common is so spelt by the Ordnance Survey, but the SSSI citation spells it Blackdown Common. {{SSSIs Somerset biological}}2. ^1 {{cite web | title=Blackdown and Sampford Commons | work=English Nature | url=http://www.english-nature.org.uk/citation/citation_photo/1003750.pdf | accessdate=2006-08-12}} 3. ^{{cite web|title=Little Breach, Blackdown Hills |work=Butterfly conservation |url=http://www.butterfly-conservation.org/reserves/little_breach/index.html |accessdate=2006-08-12 |deadurl=yes |archiveurl=https://web.archive.org/web/20060927211547/http://www.butterfly-conservation.org/reserves/little_breach/index.html |archivedate=2006-09-27 |df= }} 2 : Sites of Special Scientific Interest in Somerset|Sites of Special Scientific Interest notified in 1952 |
