In yet another example of how incompetent Hawaii's government is.
Feral pigs have established a large population in many state parks on the Big Island of Hawaii. I saw pigs in the Akaka Falls State Park (Honomu), Rainbow Falls (Hilo), and most shockingly the urban Wailuku River State Park (Hilo).
Wailuku River State Park is a small urban park surrounded by mostly empty fields and a small three block forest. The fact that they have established a large population there proves the Department of Land and Natural Resources (DLNR) are incompetent.
People from the mainland was quick to point out that precautions needs to be taken to discourage animals in general from invading urban spaces; for example, people needs to stop feeding wild animals, and trash bins needs to be secured.
They also warned that feral pigs are extremely dangerous. So dangerous -- more people die from pig attacks than shark attacks every year!
