Snail hunter

Spent an afternoon with friends wading through lichen-encrusted rocks in shin-deep water clearing invasive apple snails from what has become something like a river flowing through Bishan Park.

Instead of uprooting trees, as we usually do every year as part of our collaboration with NParks helping to maintain our natural reserves, this year it's snails. Too many, and non-native to our local environment, they've become a pest and we have to [I don't really want to know what their eventual fate is] but our job was to remove them from their unnatural habitat by collecting as many of them as our buckets would hold before dumping them into a black trash bag... and then who knows what after that?

I was initially reluctant to go snail-picking on the principle that I don't harm animals, but the apple snail website even tells us that they shouldn't have been released back into the wild in the first place. Inert and innocuous as they look, they are still clogging up the waterways and generally messing up the existing ecosystem as they have no natural predators to keep their numbers viable.
