corridor lecture

Question 1

road corridor?

Answer 1

the road and associated. so the road itself and the verge.

Question 2

what does functional connectivity mean?

Answer 2

includes species specific aspects and their interaction with landscape elements

Question 3

stream corridors:

Answer 3

border water courses and vary in size as stream size changes.

Question 4

what are line corridors?

Answer 4

narrow bands dominated by edge species. To narrow for interior species.

Question 5

what are remnant corridors?

Answer 5

corridors that develop from disturbance of the surrounding matrix. ex.) grassland vegetation between propertys or patches

Question 6

6 benefits of small patches?

Answer 6

1. stepping stones between learger patches 2. specialized habitat for certain species 3. easier to monitor and less $$ 4. may be able to identify and eradicate every invasive species 5. high spcies densities/population of edge species 6. increae heterogentity of the matrix.

Question 7

regenerated corridors:

Answer 7

corrdiors that develop from regrowth of plants in a disturbed area.

Question 8

what is a planted corridor?

Answer 8

corridors that have been panted to a desired type of vegetation ex.) shelter belts

Question 9

4 negative to small patches?

Answer 9

1. could also be more expensive if lower quality habiatats 2. many small patches may have many invasive species 3. more susceptible to invasive species 4. less species diversity/species richness

Question 10

disturbance corridors:

Answer 10

are corridors that develop from linear disturbances in the landscape, disappearing as succession proceeds ex.) power lines or game trails

Question 11

what did pluie the wolf make clear?

Answer 11

creating large wildlife corridors! A single national park is not large enough for wildlife!

Question 12

what is a characteristic of a human corridor?

Answer 12

linear and straight

Question 13

do corridors have to be structurally connected?

Answer 13

no, they can just be functionally connected

Question 14

define corridor:

Answer 14

is a linear habitat embedded in a dissimilar matrix that usually connects 2 or more larger blocks of habitat.

Question 15

strip corridors:

Answer 15

have an interior of open areas, wide enough. a good example of a strip is a road.

Question 16

negative for larger patches? 5

Answer 16

1. larger area to monitor 2. more complex 3. expensive 4. may be hard to eradicate species 5. disturbance could be larger scale and worse

Question 17

what are the 5 corridor functions?

Answer 17

1. Habitat: edge conditions, interior conditions, any internal entitys like roads or streams. 2. conduit: corridors can act as a conduit for movement of species. could be the movement of a species down a trail 3. filter: like a stream or fence line like mule deer 4. source: like a source of resources for the animal 5. sink: literally just means road kill a place of dead shit

Question 18

what are 8 benefits to large patches?

Answer 18

1. higher species diversity and richness 2, larger carrying capacity/more resources 3. supoort larger mammal species with greater home ranges 4. greater resistance to invasives 5. able to incorporate disturbances through management 6. a disturbance might not burn the whole plot 7. multiple habitat sties 8. source for specieis for other patches

Question 19

what are all the types of corridors?

Answer 19

1. environmental resource corridors 2. planted corridors 3. remnant corridors 4. regenerated corridors 5. disturbance corridors 6. stream corridors 7. road corridor

Question 20

define environmental resource corridor:

Answer 20

are the product of linear disributions of resources through space and are relatively permanent
