Invasive Animals
Invasive animals pose another major threat to Hawaii’s environment. Some of Hawaii’s invasive animals include: pigs, goats, sheep, rats, wild cats, wild dogs, frogs, and chameleons. Each one of these animals has a negative impact on the environment. Rats, cats and dogs all prey on native birds, while frogs and chameleons prey on insects, some of which are native.
One of Hawaii’s worst invasive animals is the pig. It up roots native plants leaving a wallow where rain collects. Mosquitoes then breed in these wallows. Mosquitoes carry a disease called avian malaria that most of the time is fatal for native birds. A by-product of the pig’s destruction of the rainforest is erosion. When heavy rain falls in the rainforest, which it often does, the areas that have been rooted out by the pigs will flow into the stream and then down into the ocean. The earth that has come down from the mountain acts like a red cloud smothering the reef and preventing sunlight penetration. This kills the reef and many other sea creatures. This damage can be spotted in many areas of the state including the Westside of Kauai and the Southside of Molokai. Truly what happens in the rainforest on the top of mountains will be felt all the way to ocean.
The invasive species problem in Hawaii
The silent invasion of Hawai'i by insects, disease organisms, snakes, weeds, and other pests is the single greatest threat to Hawaii's economy and natural environment and to the health and lifestyle of Hawaii's people. Pests already cause millions of dollars in crop losses, the extinction of native species, the destruction of native forests, and the spread of disease. But many more harmful pests now threaten to invade Hawai'i and wreak further damage. Even one new pest--like the brown tree snake--could forever change the character of our islands. Stopping the influx of new pests and containing their spread is essential to Hawaii's future well-being.
Despite the efforts of more than 20 state, federal, and private agencies, unwanted alien pests are entering Hawai'i at an alarming rate - about 2 million times more rapid than the natural rate. In 1993, the federal Office of Technology Assessment declared Hawaii's alien pest species problem the worst in the nation. Hawaii's evolutionary isolation from the continents, and its modern role as the commercial hub of the Pacific make these islands particularly vulnerable to destruction by alien pests. Gaps in current pest prevention systems and a lack of public awareness add further to this serious problem.
