Manomet: Climate Change Vulnerability Assessment for Shorebird
-
The Climate Change Vulnerability
Assessment for Shorebird Habitat (CCVASH)
is an innovative, Excel-based
assessment and decision-making tool that
was developed during 2009/2010 by the
Manomet Center for Conservation Sciences's
Shorebird Recovery Project [4] in partnership
with the United States Fish and Wildlife
Service (USFWS [5]) Northeast Region’s
Division of Refuges. This partnership, funded
in large part by the generosity of individual
Manomet donors concerned about climate change impacts on shorebirds, enabled Refuge
Biologist Dorie Stolley to develop and pilot the tool during a one-year assignment to
Manomet.

Modeling spatially varying landscape change points in species occurrence thresholds
-
by T. Wagner and S. Miday, Abstract. Predicting species distributions at scales of regions to continents is often necessary, as largescale
phenomena influence the distributions of spatially structured populations. Land use and land cover
are important large-scale drivers of species distributions, and landscapes are known to create species
occurrence thresholds, where small changes in a landscape characteristic results in abrupt changes in
occurrence. The value of the landscape characteristic at which this change occurs is referred to as a change
point. We present a hierarchical Bayesian threshold model (HBTM) that allows for estimating spatially
varying parameters, including change points. Our model also allows for modeling estimated parameters in
an effort to understand large-scale drivers of variability in land use and land cover on species occurrence
thresholds. We use range-wide detection/nondetection data for the eastern brook trout (Salvelinus
fontinalis), a stream-dwelling salmonid, to illustrate our HBTM for estimating and modeling spatially
varying threshold parameters in species occurrence. We parameterized the model for investigating
thresholds in landscape predictor variables that are measured as proportions, and which are therefore
restricted to values between 0 and 1. Our HBTM estimated spatially varying thresholds in brook trout
occurrence for both the proportion agricultural and urban land uses. There was relatively little spatial
variation in change point estimates, although there was spatial variability in the overall shape of the
threshold response and associated uncertainty. In addition, regional mean stream water temperature was
correlated to the change point parameters for the proportion of urban land use, with the change point value
increasing with increasing mean stream water temperature. We present a framework for quantify
macrosystem variability in spatially varying threshold model parameters in relation to important largescale
drivers such as land use and land cover. Although the model presented is a logistic HBTM, it can
easily be extended to accommodate other statistical distributions for modeling species richness or
abundance.

MUST READ: 2012-11-01_SALCC Draft NR Indicator Process
-
From the draft document: "Why are indicators needed?
Designing and evaluating the success of a shared blueprint for landscape conservation actions
in the South Atlantic will require some specific measures of what success would look like for
natural resources. The ecosystems of the South Atlantic are complex and indicators help
simplify the modeling and monitoring of those systems. We cannot measure everything all of
the time. Indicators are designed to integrate many ecological functions and represent other
components of the system that are either too expensive or time consuming to model and
measure." [And] "How will indicators be used?
Indicators will be used to help design a shared blueprint for landscape conservation actions that
sustain natural and cultural resources in the South Atlantic region. This blueprint will include
an interactive map depicting the key places and actions needed to sustain those resources in
the face of future change (e.g., urban growth, climate change, sea level rise). Indicators and
measurable targets for those indicators will be used to help design this interactive map and
evaluate the effectiveness of actions based on it."
