The forest at the Guam National Wildlife Refuge Ritidian Unit is made up of many different plants and trees some of which produce beautiful flowers and fruits. These forests support an array of wildlife, such as birds, insects, lizards and crabs. The refuge also hosts a very large population of native butterflies. The blue-banded king crow can be found in great numbers throughout the forest and along the beaches. Visitors will also find geckos, skinks and crabs throughout the refuge in abundance. Marine life is evident throughout the refuge, from fossils on the cliff walls to the beautiful coral reefs that make up more than two thirds of the total refuge area.
