How much floodplain forest, wetland and riverine habitat do we need to conserve viable populations of the 10 focal species selected for the Upper Mississippi River?
What landscape configuration would most efficiently and effectively conserve viable population of the species.
Change LC acres
(Alternative Landscape Development)
Habitat 1 = X acres Habitat 2 = X acres Habitat N = X acres
Sp 1 1 0 3
Sp 2 0 2 1
Sp 3 0 0 3
Sp N 2 1 1
Figure the number of acres needed to support 1 breeding pair/staging individual
3. Detectability (ease of and cost) for monitoring it.
4. Uncertainty about a particular species limits our ability to chose among alternative actions.
We then use the focal species for monitoring how well our observations at t1 meet our model predictions at t1 (i.e. meet our objectives)
Least Tern American Bittern Black-crowned Night Heron Paddlefish Canvasback Beaver
Red-headed Woodpecker Prothonotary Warbler Sm. Mouthed Salamander Pileated Woodpecker
Example: If we have 70 breeding pairs we can calculate the probability of extinction = 0.9
No. of Individuals/prs
No. of Individuals
Where we don’t know the size of a species population we can choose a population range to determine probability of extinction
No. of Individuals
Warner colors equate to clustered, larger patches
