FORESTRY K4 '25 Flashcards

my adapted version

Lodgepole pine

high elevations, shade intolerant. Used for framing and paneling in construction, poles, and pulpwood

white spruce

prefers moist soils. Used for paper, lumber, crates

black spruce

cold, swampy sites. serotinous cones. Used for lumber, poles, pulpwood, spruce gum, essential oils

balsam fir

well-drained sites next to spruces and birches. Used for paper and lumber, "canada balsam" resin used to make microscope slides and traditional medicine

engelmann spruce

paper, lumber, instruments like guitars and violins

aspen

highly adaptable. Fast growth—> light but strong wood used for furniture and pulp and paper, used to rapidly reforest areas

white birch

pioneer species. Used for furniture and flooring and plywood, bark used by to make traditional canoes and containers, sap used for syrup or birch beer

balsam poplar

shade-intol pioneer. Light wood used for cheap pulp, paper, crates, resin from buds has medicinal purposes

official provincial tree of Alberta

lodgepole pine, may 1984

Sentinel 2

revisits locations every 10 days, high resolution, multispectral

landsat 8

revists locations every 16 days, medium resolution, multispectral

red satellite image

healthy growing vegetation

green satellite imagery

bare ground

black purple satellite imagery

water bodies

analog format

satellite image

digital format

represented as arrays of pixels, with each pixel corresponding to a number that represents the brightness of the pixel

Reconnaissance mapping

forest cover type discrimination — monitoring type of forest by dominant tree spp, monitoring depletion, agroforestry mapping

Commercial forestry

forest inventory—biomass, density, and species inventory—mapping where to put infrastructure, then later regeneration monitoring

Environmental monitoring

deforestation, species inventory, watersheds, coastal protection

Forestry applications of remote sensing

Reconnaissance mapping, Commercial forestry, Environmental monitoring

uses of multispectral imaging

lower resolution but cheaper and frequent. Can ID cover type and general vegetation. Good for reconaissance monitoring since updated regularly

hyperspectral imaging uses

very detailed. Can detect specific species, calculate stem counts, % crown closure, and avg crown area, and id pest infestations on particular trees

Airphotos and othophotos uses

expensive, good for local imagery and species typing

SAR and radar sensors

can see through clouds in humid areas

Inventory branch

responsible for a database of Crown Land Info about sustainable forest management used to determine timber volumes and AAC

describe the two technologies used in burn mapping and how they help

thermal imagery used to see through haze and smoke to map actively burning fires with quick turnaround times. Multispectral imagery used on recently burned areas (black at first, then regrow) to monitor regeneration. Together, you can see the past trajectory of the fire and predict its path
