Giant African Snail |
|
The Giant African Snail was brought to Hawai‘i in the 1930s to "decorate" backyard gardens. This backyard alien multiplied quickly and became a nuisance. In the 1950s the Department of Agriculture introduced the Cannibal Snail in an effort to control the African Snail population. The population of the African Snail did decline, but the Cannibal Snail cannot be credited for this. Alien invasions often follow a pattern of population explosion, then eventual decline. While the African Snail is no longer a problem, the Cannibal Snail is now a serious threat to native species. |
