Status of sea anemones in Anemone Cave, Acadia National Park
Petraitis P. 2007. Status of sea anemones in Anemone Cave, Acadia National Park. National Park Service
Field Work: 23 August 2007. A census of the anemones (3 species = Tealia (=Urticina) felina, Bunodactis stella, and Metridium senile) in the Anemone Cave was conducted on 23 August 2007 using methods that would be directly comparable to earlier censuses. All three species of anemones have declined from 1999 to 2007: Tealia felina declined by 71%, Bunodactis stella declined by 63%, and Metridium senile declined by 33%. Reasons for this decline could include trampling by tourists, lower salinity levels in the pools during low tides, or run-off from the parking lot above Anemone Cave.
