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 ...
Sun scald is the freezing of bark following high temperatures in the winter season, resulting in permanent visible damage to bark. Fruits may also be damaged. Fruits may also be damaged. In the northern hemisphere, it is also called southwest injury .
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 wood is dense and very hard, difficult to plane, but drills, sands and turns well. It is termite resistant. It was once used for railway sleepers and is now prized for ornamental work and furniture. It burns very slowly with intense heat, and is often used for a fire which is intended to burn all night in order to keep wild animals at bay.
Non-wood forest products (NWFPs) [2] are a subset of NTFP; they exclude woodfuel and wood charcoal. Both NWFP and NTFP include wild foods. Worldwide, around 1 billion people depend to some extent on wild foods such as wild meat, edible insects, edible plant products, mushrooms and fish, which often contain high levels of key micronutrients.

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.
This setup allows large chunks of food (usually meat or fish) to be more easily processed compared to other methods, but is quite slow. Belt freezers simply put a conveyor belt inside a cold room. Tunnel freezing is a variant of air-blast freezing where food is put onto trolley racks and sent into a tunnel where cold air is continuously circulated.
A fir tree snag among living fir trees. In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris.
