Parks, Protected Areas, And Forestry Flashcards
ecological integrity
means keeping ecosystems healthy and whole– a state where ecosystem biodiversity, structures and functions are unimpaired and likely to persist.
national parks
- very restricted development in parks
- operated by the federal government
- run on the principle of ecological integrity
- reference point is what the environment was like BEFORE the humans were there
provincial parks
- use a model of the three pillars of sustainable development: environment, social well-being, economic development
- human interests and resource development is as important as protecting the resource
fragmented habitats
- create stress on the organisms
- they may want to move from one “island” to the next
- fragments restrict the population and mess with genetic diversity
biosphere reserves
- zone of co-operation
- buffer zones
- corridors
- core areas
minimum viable population (mvp)
estimated smallest population that can maintain itself and its genetic variability indefinitely
wildlife corridors
underground and above ground passages/corridors for the wildlife to move from “island” to “island”
core areas
area where natural processes are allowed to continue with as little development impact as possible and explore multiple ways to integrate with the neighbouring working landscapes
zone of cooperation
resources are utilized and managed in a sustainable manner in ways that support the conservation objectives of the protected and working landscapes
conservation
humans and society are in that environment (within the limits of the environment). restrictions are still in place. (provincial parks)
preservation
goal is to maintain the area the way that it was before humans came into the area. (national park)
forest ecosystem
-a plant community dominated by trees and other woody plants as well as shrubs, forbs, and grasses divided into vertical layers: canopy, shrub, forest floor
- types of trees vary to climate
- types of forests determine the types of soil that you’re going to have
- also huge in dealing with carbon and the way that water flows
stresses to Canada’s forests
- logging
- mining
- hydroelectric development
- climate change
- acid precipitation
second(ary) growth
regenerating forest after natural disturbances or forestry operations (10-50-100 years)
- trees more closely spaced
- more vegetation on forest floor b/c of the succesonal stage of the forest
- less biodiversity than old growth due to presence of one canopy layer and fewer ecological niches
old growth
has attained at least 100-500 years
-unique biological features maintain certain species.
large live trees
large dead trees (snags)
large logs on forest floor
-multiple vertical layers representing different tree species in some cases
-tremendous number of ecological niches to support biodiversity
