Shrub Release

How long do browse protection nets need to stay? The photos in this gallery track the fate of trees and shrubs we planted in 2010 and 2011. We would like to remove the nets so the plants can spread out but don't know if they are big enough to withstand deer and elk browsing. The photos in this gallery document the fate of shrubs that were netted for at least the first 2 years and then released from the nets in the first week of June 2013.
