Designing Sustainable Landscapes Tidal Restrictions Metric: Final Report-October 24, 2016
-
The tidal restrictions metric is an element of the ecological integrity analysis of the
Designing Sustainable Landscapes (DSL) project (McGarigal et al. 2014). Consisting of
a composite of 21 stressor and resiliency metrics, the index of ecological integrity (IEI)
assesses the relative intactness and resiliency to environmental change of ecological
systems throughout the northeast. As a stressor metric, tidal restrictions uses an
estimate of the historic loss of mapped salt marshes in areas where they should occur
given elevation and tidal regime to indicate the location and magnitude of potential tidal
restrictions. The metric estimates the effect of potential tidal restrictions on upstream
wetland systems, including intertidal systems such as salt marshes, as well as freshwater
systems and low-lying nonforested uplands that may have once been intertidal. Metric
values range from 0 (no effect from downstream tidal restrictions) to 1 (severe effect).

Designing Sustainable Landscapes: Salt Marsh Ditching Metric
-
The salt marsh ditching metric is an element of the ecological integrity analysis of the
Designing Sustainable Landscapes (DSL) project (McGarigal et al. 2014). Consisting of a
composite of 21 stressor and resiliency metrics, the index of ecological integrity (IEI)
assesses the relative intactness and resiliency to environmental change of ecological
systems throughout the northeast. As a stressor metric, salt marsh ditching provides an
index of the relative intensity of ditching in salt marshes. Metric values range from 0 (no
effect from nearby ditches) to 1 (severe effect).

Marine Bird Mapping and Assessment
-
This project developed a series of maps depicting the distribution and probability of occurrence of marine birds in the northwestern Atlantic Ocean. The maps are intended to be used for informing decisions about siting offshore facilities; marine spatial planning; and other uses requiring maps of seabird distributions.

Piping Plovers and Sea-level Rise
-
This collaborative project provided biologists and managers along the Atlantic coast with tools to predict effects of accelerating sea-level rise on the distribution of piping plover breeding habitat, test those predictions, and feed results back into the modeling framework to improve predictive capabilities. Immediate model results will be used to inform a coast-wide assessment of threats from sea-level rise and related habitat conservation recommendations that can be implemented by land managers and inform recommendations to regulators. Case studies incorporating resilience of piping plover habitat into management plans for specific locations demonstrate potential applications.

Priority Amphibian and Reptile Conservation Areas (PARCAs)
-
Amphibians and reptiles are experiencing threats throughout North America due to habitat loss and other factors. To help conserve these species, this project will identify Priority Amphibian and Reptile Conservation Areas (PARCAs) that are most vital in sustaining amphibian and reptile populations, taking into account potential future climatic conditions.
