The main distinction among loppers is between bypass and anvil types. Bypass loppers operate like scissors, except that they generally only have one blade that moves past a jaw or hook that has an approximately square edge that is not typically sharpened and is usually concave or hook shaped in order keep branches from slipping out of the jaws.
On an anvil pruner, proper cutting is assured even if the blade swerves slightly to the left or right during cutting. As long as the blade meets the anvil at the end of the cut and fits tightly against it, the material is separated. For this reason, the blades of anvil pruners can be ground thinner than those on bypass pruners.
A harvester is a type of heavy forestry vehicle employed in cut-to-length logging operations for felling, delimbing and bucking trees. A forest harvester is typically employed together with a skidder that hauls the logs to a roadside landing, for a forwarder to pick up and haul away.
If a large tree is unable to produce enough sugars to feed the roots, it will slowly die from starvation. [4] Some people have been known to top trees in order to stimulate new growth. When a tree is topped, many adventitious shoots, known as suckers begin to grow from the wound. This is the tree's response to the sudden loss of leaves.
The tree is a "vigorous" primary succession species, growing quickly on new open ground. [4] It is a "poor competitor" in good soils, however, and the species does best in harsh terrain. Pinus longaeva is often the dominant species in high-elevation dolomite soils, where few plants can grow.
