Overall: how to grow healthy trees that make you feel good about your forest.
Accomplish goals soonerand with greater control
The outputs related to health require adequate tree growth. Sunlight typically limits tree growth. Cutting releases desired (uncut) trees from competition for sunlight.
What makes for healthy trees?
Crown closure in a spruce plantation.
You’re making an investment of time, money, and sunlight. Pick your investments carefully.
Don’t invest in a weak factory.
From Nyland, 1996. p. 355
Know your soil type and the tree species that grow well on those soils. Favor trees suited for the soil. You can’t squeeze blood from turnip.
Sandy loam, good organic matter. Sugar maple, red oak, beech, white pine.
Sand, low organic matter, very well drained. White pine, red pine.
Reduce defective trees. They have slower growth, provide inoculum, and are more likely to break during a storm.
Try to adjust spacing for equitable distance among retained trees. Not always possible.
Safe operations depend on your skill level and available equipment. Most people aren’t as good as they think they are.
