Module 6 : Preservation and Sustainability Flashcards
(10 cards)
What is conservation?
it involves the protection and management of an ecosystem to ensure natural resources are used sustainably , maintaining biodiversity through human action
Conservation ensures that …
2
-resources remain available for future generations
-habitats and species are preserved
Make 1 point for each , explaining the social , economic and ethical reasons for conservation
economic-ecosystems provide resources for local and global trade , providing future supplies and economic stability
social-ecosystems offer recreational and aesthetic value , enhancing quality of life and well being
ethical-all organisms have a right to exist and humans have moral responsibility to prevent extinction by human action
Make 1 point explaining how preservation and conservation differ
preservation involves restricting or banning human interference in order to maintain and ecosystem and its resources , whereas conservation involves human action
What is reclamation?
a type of conservation where damaged/destroyed ecosystems are restored
Define what is meant by sustainable development
management of ecosystems in a way that allows for economic exploitation of resources without them running out
What are 5 aims of sustainability?
-to ensure all humans live comfortably
-makes resources available to future generations
-preserves the environment
-supports development in less economically developed countries
-achieves more balanced consumption of resources globally , regardless of economic status
What are 4 advantages of sustainable forest management?
-it improves conservation , soil and water management
-increases price of forestry products , generating employment and income
-provides sustainable wood fuel sources
-it secures biodiversity
Sustainable forestry for small scale timber production includes what 3 processes ?
Describe each
coppicing-cutting trees close to the ground and harvesting regrowth from stumps when they are mature
rotational coppicing-coppicing different areas sequentially , allowing time for recovery
pollarding-cutting trunks higher up to prevent new shoots being eaten by animals
Sustainable forestry for large scale timber production involves what?
( SASPM)
selective cutting-only cutting largest trees to allow growth of younger ones
avoiding large exposed clearings-prevents soil erosion
spacing out plantings-reduces competition allowing for higher yields
prioritising replanting of native species-maintains biodiversity and water/nutrient cycles
managing pests and pathogens-essential for maximum yields
