I'm not sure what the culprit is (I've never owned a Juniper), but I did find a large birds nest in the tree. Much of the bark from the tree was used to construct the now-abandoned abode
I want to know if this Juniper is dying, if it can be revived, and whether it'd be worth the time for it to fill in again. As I said previously, we just moved in several days ago, and I would have been on top of this had we been living here.
