Over the years, I have assumed that Garters were terrestrial by nature, and have always provided the "low cover" like flat rocks, bark, logs and such in the terrariums.

I look at the viv pictures around here, I see lots of trees and vines in those. I have rather avoided putting tall stuff in my tanks, figuring it would just be a ladder to get up and push the top off..

So would the snakes benefit if I were to put in some trees & lock down the tops?
