The blackberries were sprayed with RoundUp Pro Max right on the valley floor. This helpful signed warned, in all caps, DO NOT EAT BERRIES. I'm sure the park's animals can read that sign and heed the warning as well.
Is nothing sacred? I understand that maybe, for some reason, the park does not want the berries there. Perhaps they are worried about them attracting bears to heavily trafficked areas. We were told that volunteers pick apples off the apple trees planted there for that reason. But volunteers cannot dig out the blackberries? Perhaps the blackberries edge out other important plant species. But seriously, can't we do something more than squirt them with pesticide and hope for the best?
