I hate slugs and snails.
Here in Hawaii we have some big suckers. They cause a lot of damage to peoples gardens and much money is spent on slug and snail bait here in the islands.
From October through December, UH Researchers have been studying slugs and snails:
…Funded by grants from the U.S. Department of Agriculture, the survey of 40 nurseries, botanical gardens and other plant-based facilities took place on six of the Hawaiian Islands. It was determined that most of the unwanted species were probably first brought into Oahu, and then spread to the neighbor islands.
“We found alien snails and slugs in all 40 nurseries in our survey,” said Cowie, chair of the Ecology, Evolution and Conservation Biology graduate program at UHM. “In total, we found 29 alien species, including five that had never been reported in Hawai`i before. We also found many species on particular islands on which they had never been reported before, and learned that alien snails were even infesting plants due to be sent to Kahoolawe as part of the restoration effort on that island…”
