Hawaiian native animals are under threat from a wide range of invading species that are threatening across the islands.

Some species including wild horses, cattle, goats and feral felines had been deliberately introduced for hunting purposes. Some species have arrived accidentally onto the islands e.g. the Puerto Rican coqui frog. Years later, these species anr now causing trouble for native creatures.

Between 300 and 500 species are causing damage to animal and plant life in Hawaii. A pack of 4 dogs were hunted and killed after they were held responsible for over 100 deaths of wedge-tailed shearwaters at Ka'ena Point State Park. Native plants have also proed vulnerable to foraging by some of the invaders.
