This is a selfish post. I'm going to track the damage that local squirrels are doing to my plants for 2011 and (hopefully) the result of my battles against them. Hope nobody minds.
On 3/27, squirrel(s) Ate all the leaves off my MBVS on 3/27, dug up my Negronne and Col de Dame. Negronne not looking so good, MBVS is probably dead if it can't send out another shoot from the pencil-thin single branch stub left. Col De Dame had half the root base gone and 1/4 of the soil missing from the pot. One of my Italian Honey was totally dug out of the pot and laying on the ground. They also dug up a lot of the soil from my Strawberry, Fico Preto, Native d'Argentile, Scott's Black and Sal (Gene).
On 3/28 they managed to get past my netting and attacked my Sudliche Weinstrasse, broke off one of two branches and dug out the entire top 2" of roots. They re-dug my Native D'Argentile, it's down to about 1/4 of the roots at this point and had to be repotted and tamped. They did moderate digging in my Beall, Excel (which is supposed to go to a figfriend), Black Madeira, another Fico Preto and Uknown Voiture.
I thought I patched the hole they got into. Today, 3/29, I went out. Native D'Argentile is hit again with new potting soil. Dug out completely. No roots left. They partially dug out 143-36, Foxcroft, Strawberry (again), Conadria and Bethlehem Black. They did moderate digging on my 2-3gal Raspberry Latte, GM#1, Kadota, Gino's Black and Flanders. Flanders was actually pretty rough. I also found a 6" tall pecan tree growing in my Bethlehem Black today. Nut was fully intact and it had an 8" taproot on it. I tried to fortify (again) the small patch they seem to have come in through.
So far I'm looking at 2-3 likely dead trees, 2 that could go either way, and 1/3 of my collection has been dug at.
