rain water harvesting tree covers - available for free

Hello team.  I can't even remember what these are called, who makes them or were I got them...  They are used to suppress weeds and direct dew and rain water to newly planted trees and shrubs.  I used them about 6 years ago to start a bunch of fruit and nut trees.  The good news is they do indeed suppress weeds/grass and direct water right to the new tree.  The bad news is they attract rodents.  They seam to make a perfect environment for mice.  

Anyway I have about 50 of them and they are free for the taking.  I live West of Portland, OR and I'd gladly give them to a Permie who can use them.  See pictures below.  

It's been a while since I've been to Permies...  if there is a better place to post this or I have broken a rule of some sort please advise.  

Thanks team.  

What did the mice do? They sound like something that might be helpful to me. We have plenty of cats so the rodent thing might not be to big a problem for me.

The mice/rodents started eating the bark off the new trees.  I  tried wrapping them but that did not deter them.  I finally made and used the Sepp Holzer bone sauce and it worked fine.  

I find in my area I really have no problem getting new trees to grow regardless if I use these or not.  

Stacy, or anyone else who would like them, purple mosseage me when you'll be in the Portland area and we'll coordinate a meeting to get them too you.
