Scientists say in a new study that the return of gray wolves has dramatically altered the landscape in portions of Yellowstone National Park by curbing foraging elk herds that prevented new aspen, willow and cottonwood trees from taking root.Study author William Ripple from Oregon State University said tree stands are expanding in areas where for decades dense elk populations prevented new growth.
Don't see it happening with our dense human population.
We do have predators now the prey on young deer. But, only one(humans) that preys on adults. If we just could get longer doe seasons, we could do the job. It is the reduction in doe season length for political reasons that will lead to problems in a few years.
