geo forestry Flashcards
old growth forests
trees over 200 years old.
High timber volumes, while second growth on these sites will have much lower volumes.
Innovations that allowed mills to be located far away from logging opperations.
Oxen and horses, steam driven donkey machines, forest railways, helicopters, rafting logs and bundle booms.
Issues around clear cutting
loss of wildlife, habitat, erosion, impacts on rivers and streams, and water quality on fish habitat.
Forest practices code
reduced the size of clear cuts and brought in stream protection measures. decommissioning of old logging roads, replanting, and stream restoration.
Forest practices board
established by provincial government to inspect forestry practices.
Tenure
Land granted to companies to harvest provincial forest lands. The government gets revenue in return.
Timber supply areas
forest land available for harvest is divided into timber supply areas throught the province.
Tree farm licence
Tenure type; large area based tenure that gives forest companies 25 years of exclusive harvesting rights in a certain area.
Companies are responsible for all forest management in the area.
Forest licence
tenure type; 15 year renewable term.
annual allowance cut
rate of harvest set, or volume of wood allowed to be harvested for each tenure in each timber supply area.
CORE
they did several studies and undertook broad land use plans on VI, Cariboo, and the West and East Kootenays.
Outlined what areas should be protected and what areas could be used for resource extraction, including logging.
culmination age
the age at which the tree reaches an economic profitability stage. There is enough wood on the tree to make it profitable to cut.
the fall down effect
results in the annual allowance cut up to 30 percent as old-growth forests are eliminated and there is not enough trees that are second growth to fill the gap.
eco-forestry
refers to new ways of looking at the management of forest ecosystems.
ecosystem based approach to forestry
the focus is maintaining ecosystem functions, forestry is important, but isn’t the highest priority.
