FORESTRY TERMS.

Byline: The Register-Guard

The language used in the debate about logging has evolved in the past 13 years. Today, planners don't talk about clear-cutting but regeneration harvest. Old-growth is now late-successional. The Bureau of Land Management in its revised management plan for Western Oregon forests has further refined the language around trees. Here are the terms and what they mean:

Stand establishment:Very young forest of trees less than 50 feet tall and without larger trees

Young:Taller than stand establishment, but still small and without larger trees

Mature with single layer canopy:Larger trees with little variation in tree size

Mature with multilayered canopy:Larger trees with more than one canopy layer

Structurally complex:Larger trees with some very large trees and more than one canopy layer

Existing old forest: Stands currently 200 years or older

Structural legacies:Larger trees mixed in with younger stands
