Forestry exam elaborations 2025
Natural resources
Products of natural ecosystems that we harvest to sustain and support life.
Renewable natural resources Water, fish, forage, wildlife, & forests
Overharvesting
How can a natural resource become a non-renewable resource?
Natural resource industries
Mining, petroleum extraction, fishing, hunting, and forestry.
Agriculture
Industrial user of natural resources
Wildlife Management to apply scientific knowledge to manipulate a population to reach a
goal
Conservation wise use of resources
What is forest management?
1. a catch-all term used to describe any activities relating to humans working to
extract resources from or alter the properties of forests.
2. a term used to differentiate between preserved forests and those that are harvested.
what are the components of production forestry?
felling, extraction, harvest strategies
type of felling
manual, mechanized
timber extraction
removing trees after felling
clearcutting
take out all the trees
seed-tree method
leave a few trees to seed new trees
shelterwood method
leave patches of trees to seed new trees and create "shelter" from wind disturbance
thinning/release cutting
removing some trees to give the remaining trees more "space" to grow
low thinning
removing the shorter trees with "lower" crowns
crown thinning
removing the alternate co-dominant crowns to stimulate growth
selection thinning
removing the trees with the dominant crowns
mechanical/row thinning
removal of trees to facilitate mechanical harvesting
salvage cutting
harvesting dead or dying trees after a disturbance before the wood rots
site preparation
before planting methods to ensure rapid growth and success of trees
advantages and disadvantages of natural regeneration
Advantages
- Lower costs
- Less labor and equipment
- Local seed stock (usually)
