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 trees. Construction projects sometimes avoidably damage trees.
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 ...
For example, arborists are frequently called upon to analyze the danger posed to people or property by a damaged or decaying tree. By knowing how decay is likely to spread, such hazard tree analyses may be more accurate, thereby preventing unnecessary tree removal, property damage, or injury. [citation needed]
Wood decay caused by Serpula lacrymans (called true dry rot, a type of brown-rot). Fomes fomentarius is a stem decay plant pathogen Dry rot and water damage. A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot.
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.
The U.S. began mandating the use of non-arsenic containing wood preservatives for virtually all residential use timber in 2004. The American Wood Protection Association (AWPA) standards for ACQ require a retention of 0.15 lb/cu ft (2.4 kg/m 3) for above ground use and 0.40 lb/cu ft (6.4 kg/m 3) for ground contact.
A log jam is a naturally occurring phenomenon characterized by a dense accumulation of tree trunks and pieces of large wood across a vast section of a river, stream, or lake. ("Large wood " is commonly defined to be pieces of wood more than 10 cm (4 in) in diameter and more than 1 m (3 ft 3 in) long.) [ 1 ] Log jams in rivers and streams often ...
Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
