16
Q

How does upland vegetation effect the health of the watershed

A

affects infiltration rates and slows erosion

17
Q

Characteristics of healthy streams

A

steep, undercut banks. abundant riparian vegetation

18
Q

Two causes of erosion

A

lack of vegetation, increasing slope

19
Q

Why are horses so bad for watersheds?

A

non-cloven hooves compact soil. They are very heavy. They eat a lot bc hindgut fermenters. They are not managed. Horses are territorial.

20
Q

What is the history of the beaver in the Great Basin?

A

fur trappers decreased their numbers but farmers (pioneers) finished them off by destroying their dams

21
Q

Evidence of past overgrazing

A

upland vegetation abutting streambank

inset floodplains and cutbanks

22
Q

why is the GSL salty?

A

calcareous soils formed from limestone formed under a shallow ocean

23
Q

Know the definition of remote sensing

A

the acquisition of information about an object without coming into direct contact with it

24
Q

Raster definition

A

simple grid structure. Each cell assigned one value. Simple data structure, faster to use

25
Q

Vector definition

A

points, lines and polygons. more complex data structure.

26
Q

LANDSAT features

A

30x30M resolution, 8 day temporal resolution. Smaller data file. Has more bands

27
Q

three causes of conflicts

A
  1. information (we can fix this with good science)
  2. interests
  3. values
28
Q

Conflict resolution

A

information fixes this. win/win

29
Q

conflict management

A

requires compromise, everyone comes away with something

30
Q

(conflict) litigation

A

negative experience for all, no one goes away happy

31
Q

(conflict) violence

A

if people are really unhappy about something, it may come to this.

32
Q

Strategies for protecting forests

A

Large-scale homogeneity (scale of 10s of Ks) and medium-scale heterogeneity (10s to 100s of meter)

33
Q

Problems associated with NEPA

A
  • adds considerably to the cost of doing projects. Less gets done
  • adds a lot of time to projects
  • makes decision making a public process
34
Q

Rapid development of drone-releated technology

A

2003: drones first experimentally used for rangeland management
2006: first commercial use of drones
2017: Over 60,000 remote pilot certificate holders

35
Q

Rapid development of drone-releated technology

A

2003: drones first experimentally used for rangeland management
2006: first commercial use of drones
2016: FAA requires drone fliers to acquire permits
2017: Over 60,000 remote pilot certificate holders

37
Q

Impacts of homogenizing forests

A

Not aesthetically pleasing, habitat loss for certain species, forests become more vulnerable to stresses, decrease long-term yield

38
Q

Name some projections, their strengths and weaknesses

A

Planar projection - projects a small area of the spheroid onto a flat plane. This projection is good when the area of interest is small

Lambert’s conformal - This projection preserves angles, but distorts sizes and shapes. It’s a good one to use for navigating

Mercator - a cylindrical projection with the poles parallel to the long edge of the cylinder. Does not represent the poles well, so best suited for representing areas near the equator

Transverse Mercator - a cylindrical projection with the poles perpindicular to the long edge of the cylinder. Good for representing N-S oriented objects.

Equidistant projection - preserves all distances, but distorts shapes and sizes. Good for navigating when determinig distances is of most importance
