Absolutely. A healthy eco-system includes species and age
diversification. As in farming and gardening, mono-cropping is fraught
with problems.
A friend, David Haenke, who manages a several-thousand-acre private
forest, introduced me to Clint Trammel, who is Forest Manager for
Pioneer Forest near Salem, Missouri. PF consists of about 160,000
acres, all owned by businessman, Leo Drey. For half a century PF
foresters have been practicing a single-tree harvest practice.
Opposite of normal logging, the practice takes out the worst trees and
leaves the best, making sunlight, water and nutrients more available
to the best trees, including mother trees that seed the floor. The
practice thus continually upgrades the forest, making it ever more
valuable.
David brought Clint to Heartwood some years ago to advise me before I
did a modest amount of logging. Clint's knowledge is huge. It was a
wonderful afternoon of keeping my mouth shut except to answer
questions and mostly soak up information as fast as I could while we
walked through the forest of Heartwood, a mere 130 acres of oak, pine,
hickory and other valuable trees.
