The forests the National Park Service inherited were diverse, the product of thousands of years of unplanned development. In the 19th century German foresters rejected unplanned evolution in favour of design. You can still see such planned forests in many countries of Europe and North America: the trees are identical and evenly spaced… These forests are generally ugly, but were not very successful in economic terms, far more prone to accident and disease than the planters had anticipated. The foresters saw the trees but not the wood. You cannot necessarily deduce the properties of the whole by adding up the properties of the individual parts.
