I've been replanting Douglas firs (and a Giant Sequoia) so hopefully by the time the last of them die off - the other trees will fill the gaps. Truthfully, I'm concerned about the "cedar" trees (giant arborvitae) - all of the trees at my place are 2nd or even 3rd growth so what is here may not be what was here before they logged it to build boats for the Alaskan gold rush... still, I hope the sequoia experiment works (they are maybe 18" tall right now).
