A continuous cover of branches and foliage formed collectively by the crowns of adjacent trees consisting of one several layers.
A log that has been slabbed on one or more sides.
The release of carbon from a source such as but not limited to living organisms, fossils fuels, and volcanic emissions into the atmosphere over a specified area and period of time.
The result of of any action specifically undertaken to prevent the release of or to remove carbon dioxide from the atmosphere in order to balance emissions taking place elsewhere.
The process of increasing the carbon content of a carbon reservoir other than the atmosphere. Some biological approaches to sequestration include direct removal of carbon dioxide from the atmosphere through land use change, afforestation, reforestation and practices that enhance soil carbon in agriculture. Some physical approaches include separation and disposal of carbon dioxide from flue gases or from processing fossil fuels to produce fractions and long-term storage underground in depleted oil and gas reservoirs, coal seams, and saline aquifers.
A pool or reservoir that absorbs or takes up released carbon from another part of the carbon cycle. For example, if the next exchange between the biosphere and the atmosphere is toward the atmosphere, the biosphere is the source and the atmosphere is the sink.
Any process or activity which releases greenhouse gas, aerosol or a precursor of a greenhouse gas into the atmosphere.
A condition of stress and set in dry lumber characterized by comprehensive stress in the outer layers and tensile stress in the center or core
A substance, usually present in small amounts relative to the reactants, that modifies the rate of chemical reaction without being consumed in the process.
A carbohydrate that is the principal constituent of wood and forms the structural framework of wood cells.
