Cloning coast redwoods
Not available – first paragraph follows: In a redwood breeding program, time is a problem. Between germination (or planting) and harvest as a renewable source of wood, a redwood must survive and grow in a minimally managed environment for three to eight decades. Trees in park and amenity plantings may be expected to grow for centuries, or even millenia. Redwood foresters thus, and properly, tend to be conservative.
