Tree spiking involves hammering a metal rod, nail or other material into a tree trunk, either inserting it at the base of the trunk where a logger might be expected to cut into the tree, or higher up where it would affect the sawmill later processing the wood. Contact with the spike often damages saw blades, which can result in injuries, or ...
Rapid expansion and contraction of water within the wood and bark, particularly under rapidly falling night temperatures, can result in a frost crack, often accompanied by a loud explosive report. [3] Research suggests that the main cause is actually 'frost-shrinkage' due to the freezing-out of cell wall moisture into lumens of wood cells.
Trees can live for a long time but eventually die, either from natural causes or killed by man. Ill-health of trees can be diagnosed, and early treatment, pruning or felling to prevent the spread may result in timber stocks and amenity trees being saved. Tree owners and Arborists/arboriculturists need to be aware of the risk posed by hazardous ...
The trees are often scorched and burnt up, as with the most excessive heat, in consequence of the separation of water from the air, which is therefore very drying. In the great frost in 1683, the trunks of oak, ash, walnut, and other trees, were miserably split and cleft, so that they might be seen through, and the cracks often attended with ...
Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of the limbs have broken off during transport, the remaining limbs and stubs must be trimmed.
The National Park Service wants to replant sequoia groves in Sequoia and Kings Canyon National Parks, where wildfires in 2020 and 2021 inflicted lasting damage on the iconic sequoia forests.
Some plants use coarse woody debris as habitat. Mosses and lichens may cover logs, while ferns and trees may regenerate on the top of logs. Large fragments of CWD that provide such habitat for herbs, shrubs, and trees are called nurse logs. [8] CWD can also protect young plants from herbivory damage by acting as barriers to browsing animals.
The federal Centers for Disease Control and Prevention has reaffirmed the importance of properly cooking wild game after six people became sick from a parasite traced to undercooked bear meat that ...
