Artificial Regeneration - replacing the harvested forest by planting seed or seedlings Aspect - the side or surface of a mountain facing a given direction Back to Top Backfire - a burning technique used to reduce the amount of fuel in the forest.
The fire is set to burn against the wind or back into the fuel as the wind blows the flames away from the fire Barriers - obstructions to pedestrian, horse, and/or vehicular traffic.
Wiens has a Ph D in Physics, with a minor in Geology.
The tree is developing a canopy of leaves that needs a vast amount of water and minerals from the roots. The root system will need to branch out and penetrate more soil to supply the water and mineral needs.Borrow Pit - that area, usually adjacent and parallel to a road, from which soil is removed to build up the road bed Bottom Lands - a term often used to define lowlands adjacent to streams and rivers Broad-Based Dip - a surface drainage structure specifically designed to drain water from an access road while allowing vehicles to maintain normal travel speeds Buck - to saw felled trees into predetermined lengths Bucking - the process of cutting a tree into shorter lengths Buffer Strip - a narrow piece of land bordering an area such as a stream or road with forestry practices that are different from adjacent areas Bunching - grouping of trees or logs together to form a load before being transported Bundle Scar - a small scar in a leaf scar left by a vascular bundle Back to Top Cambium - a layer of cells located inside the bark between the xylem (wood) and phloem (inner bark) Caliche soil - is a hardened mineral of calcium carbonate.It forms when rain dissolves calcium found in rocks and minerals, carrying it down into the soil, so layers of deposits build up over the years.A tree typically has many secondary branches supported clear of the ground by the trunk.This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another.Trees tend to be long-lived, some reaching several thousand years old.
