This dataset depicts Marten (Martes americana) habitat in the Northern
Appalachians predicted using the spatially explicit population model
PATCH under the increased survival in parks scenario (B1; Carrol 2007).
This dataset represents one of several scenarios testing the interacting
effects of trapping, timber harvest, habitat restoration, and climate
change on marten populations. Static habitat suitability models for
marten were fed through PATCH to predict source and sink habitat areas
across the landscape. The static models for marten were created based
on annual snowfall and percentage of older conifer and mixed forest.
Demographic parameters were obtained from the literature and from
calibration of the model. Several hundred individual model simulations
were used to create this dataset. The influence of trapping was
incorporated through different scenarios of the area open to trapping
and the survival rates within trapped and untrapped areas. The
influence of timber harvest was incorporated through doubling the
percentage of regenerating forest (up to a maximum of 100%) with
corresponding decrease in the percentage of conifer/mixed forest. The
influence of restoration was incorporated through converting all
regenerating forest to conifer/mixed forest. The influence of climate
change was addressed by incorporating predicted snowfall for 2055 from
IPCC Scenario A2 into the static habitat model.
