Threats to Biodiversity Guided Viewing
1: Natural Capital: Forests
2: What are the 3 main types of forests?
- Old Growth Forest
- Second growth forests
- Tree Plantation
- Release of Co2 into the atmosphere
- acceleration of flooding
- Runoff of eroded soil into aquatic systems
- selective cutting
- clear cutting
- strip cutting
6: What are some solutions for sustainable forestry?
- Grow more timber on long rotations
- Stop clear cutting on steep slopes
- Cease logging of old growth forests
- Pros:
- Allows timber companies to only cut the medium and large trees of 71% of the national forest
- Fires are more likely to happen as the fire resistant trees will be cut.
9: What are some causes of tropical deforestation?
10: Why should we care about the loss of tropical forests?
2100 plants are cancer fighting chemicals.
11: Sustaining Tropical Forests
- They are burned to make way for cattle ranches and crops
- Poverty
- Subsides
- roads
- logging
10: Why should we care about the loss of tropical forests?
2100 plants are cancer fighting chemicals.
11: Sustaining Tropical Forests
12: Why are rangelands/grasslands so important?
A biodiversity hotspot is a place where biodiversity is really high. There are 34 worldwide. In the U.S, the top 6 hotspots are:
18: What are the eight priorities for protecting biodiversity?
It is a community based conservation.
20: Define:
21: What are characteristics of vulnerable species?
The most important causes of the premature extinction.
23: What can you do about invasive species?
24: What are some characteristics of successful invader species?
25: How is pollution affecting species?
This is when you overuse an area because of it's valuable things.
27: What is the U.S. Endangered Species Act?
An act to protect the critically endangered species from extinction.
28: What is the CITIES Treaty?
A multilateral treaty to help protect plants and animals
29: What can you do to help terrestrial biodiversity? What can you do to help protect species
worldwide?
- The formation of soil
- Control of erosion
- Cycles nutrients
- Control the distribution number of livestock and restore rangeland that is degraded
- Find and map the global ecosystems
- Find endangered ecosystems and species and protect them
- Restore many degraded ecosystems as possible
- Make development as friendly to biodiversity as possible
A biodiversity hotspot is a place where biodiversity is really high. There are 34 worldwide. In the U.S, the top 6 hotspots are:
- Hawaii
- San Francisco Bay area
- South Appalachians
- Death Valley
- South C.A.
- Florida Panhandle
- Identify the cause for the loss
- stop abuse by reducing or eliminating factors.
- If necessary, reintroduce the species
- Protect the area to stop more degradation
- Use adaptive management for monitoring
- Preservation:Protecting the areas undisturbed by himans
- Remediation: Repairing an ecosystem that is already destroyed
- Sustainability: The ability for a system to survive given a specific time.
18: What are the eight priorities for protecting biodiversity?
- Act immediately to help preservation of the hotspots
- Keep intact the remaining old growth
- Complete the mapping of the world's biodiversity for decision making
- Find the world's marine hot spots
- Make sure that all the ecosystems are in conservation or ready to be strategized
- Make conservation profitable
- Make products to heal the damage done and share the earth's land and water and the rest of nature
- Make and sustain new habitats where there are people.
It is a community based conservation.
20: Define:
- Background Extinction: A continuous and low level of extinction of the species
- Extinction Rate: A percentage or a number of species that will go extinct in a certain time period.
- Mass Extinction: Many species going extinct in a short amount of time.
21: What are characteristics of vulnerable species?
- Abundant in natural range
- Going to be endangered because of a loss of numbers.
- Large size
- Found in one place
- Low reproductive rate
The most important causes of the premature extinction.
23: What can you do about invasive species?
- Do not let wild animals be able to escape
- Don't spread wild plants into other areas
- Don't throw away unused bait into the water
- Don't swap plants using the internet from across the world
- Empty water from canoes before heady home
24: What are some characteristics of successful invader species?
- Pioneer species
- lives long
- Rate of dispersal is high
- Generalists
- High genetic variability
25: How is pollution affecting species?
- It kills and threatens them
This is when you overuse an area because of it's valuable things.
27: What is the U.S. Endangered Species Act?
An act to protect the critically endangered species from extinction.
28: What is the CITIES Treaty?
A multilateral treaty to help protect plants and animals
29: What can you do to help terrestrial biodiversity? What can you do to help protect species
worldwide?
- Adopt a forest
- Plant trees and be able to take care of them
- Live in town because suburban sprawl reduces biodiversity
- Buy a source of sustainable wood and products
- Do not buy animals and plants that are from the wild
