  • What are the Ecosystem Consequences of High-Grading?The non-negative consequences

    Increased wildlife trees Site productivity (soils) not necessarily affectedStill green

  • Negative Consequences to the EcosystemReduced diversityReduced food sourcesReduced $ value per acreIncreased disease & insect, risk to storm damageReduced volume, stocking, and qualitySlower growthExtended time to next harvest of equal volumeFuture options constrained

    This tree has optimum growth.Fusarium (solani) is a filamentus fungi widely distributed in soil. Typically harmless saprobes, though can create mycotoxins in wheat and corn. Most common in years following droughts and has been associated with extensive tree decline and stand-level mortality.

    sugar maple borer, Glycobius speciosus (Say), a long-horned wood boring beetle This slide is typical of what a hardwood sawtimber forest in New York might look like. Knowing from the previous slide that the cutting is light and dispersed, and that many forest owners dont have a management plan to guide their decision making, which trees are likely to be cut? (see the next slide)The yellow X marks the trees that are likely to be cut if decisions are opportunistic or based on only short-term economic criteria. This simulated cutting would remove the red oak (big tree on right) and the smaller white ash and cherry to the left. What does this leave behind in the forest? It leaves behind beech and red maple, and the majority of the trees. How then do we know when the forest has been high-graded?High-grading is destructive to the forest ecosystem. While there are still green trees and often defective trees good for wildlife, other qualities of the forest are degraded. Species diversity is reduced, as is the value per acre, the growth rate, tree quality, and the number of options for the future. Whats increased is the amount of time it takes for the forest to grow to the same volume and value as was harvested.
