TOPIC 9 –HISTORY OF FOREST MANAGEMENT
3
19 th CENTURY TO PRESENT PARADIGM SHIFTS SUSTAINABLE FOREST MANAGEMENT CANADIAN MODEL FOREST NETWORK
4
Forest was used by early Europeans as a means to support the FISHERY. Wood was also used to construct boats, barrels, stages, flakes, docks. buildings.
5
Land given to NL RAILWAY, who opened up the INTERIOR of NL. Granting of forest leases began (still in existence today). Sawmilling of white pine was common. No management of forest resources.
6
Pulp and paper industry grew 1909 – opening of mill in GRAND FALLS (closed 2008) 1923 – opening of mill in CORNER BROOK The only forest management was protection from FIRE AND INSECTS. Companies were given LAND LEASES and self- managed their land.

1974 – TIMBER MANAGEMENT Taken over by PROVINCIAL DEPARTMENT OF FORESTRY Pulp and paper companies submit management plans 1980s - SILVICULTURE DEFINITION: The science and practice of growing trees Silviculture is an important tool in forest management and includes activities such s: Pre-commercial thinning Site Preparation (ex: spraying, burning, tilling) Replanting 2008 27 trees planted per person in NL
9
1990 – FORESTRY ACT Requires management for timber and other forest related issues, such as : ENVIRONMENT SUSTAINABLE DEVELOPMENT HUNTING RECREATION
10
EXPLOITATION This was the 1800s forestry approach, to “log and move on” People aimed for maximum profit with no concern for the future of the forest. Some parts of the world still practice this. Ex: Slash and burn agriculture
11
UTILITARIAN This was the 1930s forestry approach, to manage forests such that the resource would not “run out” In other words, sites were reforested for future logging, but there was still little concern for the integrity of the environment.
12
ECOSYSTEM MANAGEMENT This is the present day forestry approach, to manage forests for many uses, including: Industry, employment, recreation, heritage, solitude, etc. In other words, the forest is managed as a whole ecosystem.
13
3 MAIN ELEMENTS 1.SUPPORT OF FOREST FOR MULTIPLE USE 2.PROTECTION AND MANAGEMENT of FOREST ECOSYSTEM. 3.CONTINUOUS SCIENTIFIC MANAGEMENT.
15
TWENTY YEAR PLANS CREATED BY NL FOREST SERVICE. Describes goals for next 20 years such as AAC (ANNUAL ALLOWABLE CUT). Updated every 5 years. FIVE YEAR OPERATING PLANS One of the 26 management districts in the province plan for activities such as: Domestic cutting, building roads/bridges, water supplies, silviculture, timber supply, protection
16
Created in 1992 Canada has 11 model forests that take care of the scientific portion of sustainable forest management. www.modelforest.net/cmfn/en /forests/ www.modelforest.net/cmfn/en /forests/

TOPIC 10 – HARVESTING TECHNOLOGIES
18
Clearcutting Selection cutting Old Harvesting Technology New Harvesting Technology
19
Definition: Harvesting all the trees in a cutting block 100 % of trees in NL harvested are clear-cut 90 % of harvesting operations in Canada use clear-cutting Best method for trees that are short-lived, have lots of seed, grow best in full sunlight, and form even stands naturally.
20
POSTIVES: Economical Mimics natural disturbances (ex: fire, insects) Fewer roads Less blowdowns New habitat
22
NEGATIVES: Soil erosion Water siltation Decreased water quality Small tree wastage Unsightly Loss of habitat
23
DEFINITION: Cutting of trees individually or in small groups such that up to 30 % of forest is harvested Recommended for areas that are environmentally sensitive, such as old growth forests, young stands, or uneven aged stands.
24
POSITIVES: Maximizes growth of remaining trees Maintains original forest habitat Looks nicer NEGATIVES Not as cost effective Need more roads, more workers
25
Axes and Cross-cut Saws Horse-Sleigh Water Transportation Chainsaws Feller-Bunchers Skidders
30
Logging machine that cuts trees in a place with a tree-grabbing function and a cross-cut saw LINKLINK
31
Heavy vehicle with large tires that pulls logs with a cable system from a cutting site to a landing
32
Soft footprint technology GPS Remote sensing GIS Training simulators Environmental friendly alternate fluids
33
Any technology that reduces the impact with the forest floor Some have flotation tires, anti-slip systems, walking movement LINK LINK
34
A network of 24 satellites used to locate precise coordinates on the Earth’s surface. Helps navigate and survey forest lands.
35
Any information gathering that does not require contact. Can use aircraft, satellites, space station, etc.
36
A system that can capture, analyze, and manage data which is referenced to Earth’s positions. Maps can be layered.
