The group exhibition the “Endangered Ark” at Ark of the Unicorns, 1109 Maunakea St. No. 203, celebrates Hawaii’s rare and extinct species and encourages community action in response to a national political climate that endangers conservation goals.

The participating artists are Nanci Amaka, Kirsten Carlson, Kayleigh Chalkowski, Deanna Gabiga, Ryan Schulz, Michelle Schwengel-Regala, Danya Weber and Tammy Yee. Visitors are invited to write why they value endangered species protections on postcards that will go up on a gallery wall and then be mailed to lawmakers after the closing party from 6 to 9 p.m. Friday.

The exhibit is open 4 to 7 p.m. Wednesday and 4 to 9 p.m. Friday. Visit fb.com/TheEndangeredArk for more information.
