Those big garden spiders are cool and very much appreciated in any garden just like the little common garter snakes here in NH that are also coded yellow and brown.
The most critically endangered animal in New Hampshire with only one population left in the state is the Timber Rattlesnake, a heavy black viper. The timber rattlesnake is the only snake in NH with vertical pupils. Rock crevices are used for shelter.
Yup! Timber Rattlers used to live on Rattlesnake Island in New Hampshire (
www.rattlesnakeisland.net), which is where the island got its name. People went so far as to burn the island over (back before anyone had a house there), and it didn't work - the snakes crawled deep into the rock crevasses that dominate the slopes of the island. They brought hogs over (apparently hogs go after rattlesnakes), and this along with some professional snake hunters, finally eliminated the rattlesnakes from the island. None have been seen since the late 1940s.
Personally, I'm glad they're gone from the island!
