Chapter 10 APES
Subsidize Local ranching
All of the following are sustainable practices for forest use and maintenance EXCEPT
increase in biodiveristy
All of the following would result in an area that was recently clear cut EXCEPT
promotes economic growth, damages nearby rivers and fisheries, builds more roads leading to fragmentation
Allowing logging in US National Forests
strip cutting
Allows for sustain timber yield w/o massive destruction; goes with contour, cut a narrow region
buffer zone
Areas around edges can be used sustainably; helps protect inner core of reserve
biodiversity hotspot
Areas especially rich in plant species found nowhere else, in great danger of extinction
nature reserve
Areas set up with a protected inner core for wildlife surrounded by more multi use buffer zones
life raft ecosystem
Areas w/ high poverty, needs ecosys services but being degraded, this threaten human well being
Restoration
Converting a mid-western farm back to original prairie grassland Return the degraded habitat or ecosystem to a condition as similar as possible to natural state
Rehabilitation
Covering a landfill with topsoil and planting with vegetation Turn degraded ecosys into functional/useful ecosys without restoring to original
creating artificial ecosystem
Creating a man-made wetland to help treat sewage
selective cutting
Cutting the intermediate-aged trees in an uneven-aged forest is referred to as:
preservation
Demand for fuelwood leads to enviro degradation, all have resulted from overuse except
carbon sequestration, aid in aquifer recharge, provide wildlife habitat
Ecosystem services performed by forests include which of the following
reconciliation ecology
Est and maintain new habitats to conserve species div where people live, work, and play - SHARE
clear-cutting
Farmer trying to put max amt of crops on land, would most likely use which method
crown fire
Fire suppression which allows flammable ground litter to accumulate can result in Extremely hot fires that move fast and burn whole trees, worst type of forest fire
surface fire
Fire that usually only burn undergrowth and leaf litter, most mature trees are fine, beneficial
old-growth forest
Forests reached climax community & is relatively undisturbed Uncut or regenerated forest not been seriously disturbed by human activities for long time
tree plantation
Managed area of uniformly aged trees which are grown until commercially viable
tree plantation/tree farm/commercial forest
Managed forest containing only one or two species of trees of same age, some + and - aspects
pastures
Managed grasslands or fenced meadows for domesticated grasses and forage crops
Overgrazing
Occurs when too many animals graze for too long, damages grasses and roots, then more problems
soil erosion
One effect of our overgrazing of the natural rangelands is
overuse of junk mail
One factor that results in unnecessary waste of wood in the US is
Rotational Grazing of cattle
One of the most common methods for sustainable management of rangeland is
habitat corridor
Protected the area allows the migration of The farmer & pop to MOVE/MIGRATE from one area to another. Protected areas between isolated reserves, helps support more species, migration, large ranges
replacement
Replace degraded ecosys with another type. EX - degraded forest into pasture or tree plantation
second-growth forest
Stand of trees resulting from secondary ecological succession
deforestation
Temporary or permanent removal of large expanses of forest for agri, settlements, or other uses
Russian Federation
The largest area of old-growth forest in the world is located in
logging, clearing for fuelwood, slash-burn for subsistence agri & cattle
Tropical deforestation is caused by
wilderness lands
Undeveloped lands that have been set aside as reserves by being roadless; are limited to hikers. Officially designated as natural area, not been seriously disturbed by humans
rangelands
Unfenced grasslands supply forage or vegetation for grazers
debt-for-nature swaps, conservation concessions
Way to make it financially attractive for countries to protect their tropical forests
Popularity and its impact
What is the overall largest problem facing most US national parks?
clear land for mining
Which of the following is NOT a cause for tropical deforestation?
replanting a destroyed area back to natural state
Which of the following would be an example of restoration of disturbed lands?
Tropical rainforests have much higher biodiv than temp forests
Why is deforest in trop RF more devastating to the global enviro than deforest in temp forests?
industrial wood
Wood for lumber and paper
5% & 20%
______% of land strictly protected from harmful human activities; ______% biologists want protected
kenaf and hemp, rice straw and agri residues
alternatives to using trees for paper.
Ecological restoration
repairing damage caused to the biodiv of natural ecosys
fuelwood or biofuel
using wood for cooking and heating
