Of time and wounds
Willows are pioneers of raw, moist habitats (“Have returning wolves really saved Yellowstone?” HCN, 12/8/14). Except for the few, but often common, species capable of vegetative reproduction, dense grasses are anathema to willow spread, and young plants grow fastest. The story of moisture-loving riparian species, such as willows and sedges, catching sediments is writ large…

The author covered one aspect of a complex subject rather well, but he left out several pertinent facts. Hatchery-bred fish do not…
