corridor lecture Flashcards
road corridor?
the road and associated. so the road itself and the verge.
what does functional connectivity mean?
includes species specific aspects and their interaction with landscape elements
stream corridors:
border water courses and vary in size as stream size changes.
what are line corridors?
narrow bands dominated by edge species. To narrow for interior species.
what are remnant corridors?
corridors that develop from disturbance of the surrounding matrix. ex.) grassland vegetation between propertys or patches
6 benefits of small patches?
- 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.
regenerated corridors:
corrdiors that develop from regrowth of plants in a disturbed area.
what is a planted corridor?
corridors that have been panted to a desired type of vegetation ex.) shelter belts
4 negative to small patches?
- 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
disturbance corridors:
are corridors that develop from linear disturbances in the landscape, disappearing as succession proceeds ex.) power lines or game trails
what did pluie the wolf make clear?
creating large wildlife corridors! A single national park is not large enough for wildlife!
what is a characteristic of a human corridor?
linear and straight
do corridors have to be structurally connected?
no, they can just be functionally connected
define corridor:
is a linear habitat embedded in a dissimilar matrix that usually connects 2 or more larger blocks of habitat.
strip corridors:
have an interior of open areas, wide enough. a good example of a strip is a road.
negative for larger patches? 5
- larger area to monitor 2. more complex 3. expensive 4. may be hard to eradicate species 5. disturbance could be larger scale and worse
what are the 5 corridor functions?
- 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
what are 8 benefits to large patches?
- 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
what are all the types of corridors?
- environmental resource corridors 2. planted corridors 3. remnant corridors 4. regenerated corridors 5. disturbance corridors 6. stream corridors 7. road corridor
define environmental resource corridor:
are the product of linear disributions of resources through space and are relatively permanent
