[1] They have been designated a Restricted Zone under ASMA 7 — Southwest Anvers Island and Palmer Basin — which includes the marine area extending 50 metres (55 yd) from the shorelines.

Their vegetation, which is typical of the region, consists of a variety of mosses, lichens and algae, as well as the flowering plants Antarctic Hairgrass and Antarctic Pearlwort.

[2] The islands have been identified as an Important Bird Area (IBA) by BirdLife International because they support a breeding colony of about 250 pairs of imperial shags.

Other birds nesting on the islands include Adélie, gentoo and chinstrap penguins as well as southern giant petrels.
