Nature’s Network is a collaborative effort led by the U.S. Fish & Wildlife Service and representatives from all 13 Northeast states, using innovative modeling approaches developed by UMass Amherst and other science partners, to identify the best opportunities for conserving and connecting intact habitats and ecosystems and supporting imperiled species, to help ensure the future of fish and wildlife across the Northeast region. Nature’s Network offers a regional landscape conservation design and a suite of decision-support tools that makes available much of the state-of-the-art modeling done by the Designing Sustainable Landscapes (DSL) project at UMass Amherst. The web mapper interface presents a huge variety of customizing options, that frequent users will familiarise themselves with and use. Nature’s Network incorporates, DSL Ecological Integrity Metrics, DSL-Conductance, and Resilient & Connected Landscapes. Elements of Nature’s Network include:

• Terrestrial and Wetland Core Network: Intact, well-connected places that, if protected, will support a diversity of fish, wildlife, and plants, and the ecosystems they depend upon. Core areas are linked together by a network of connectors designed to enable the movement of animals and plants between core areas and across the landscape into the future.
• Habitats for Imperiled Species: This contains three datasets: Habitat Importance for Imperiled Species, Core Habitat for Imperiled Species, and Habitat Condition for Imperiled Species.
• Aquatic Core Networks: This includes three data layers: River and stream (lotic) core network, Lake and pond (lentic) core network, and Aquatic buffers.
• Marsh Migration Zones: This dataset depicts potential salt marsh migration zones at various sea level rise scenarios from 0-6 feet. Identification of suitable uplands adjacent to tidal wetlands is based on topography, habitat type, land use, and development, and can be used for facilitating marsh migration through land protection and/or management.
• Regional Flow: This dataset, developed by The Nature Conservancy, identifies where population movements and potential range shifts may become concentrated or where they are well dispersed, and it is possible to quantify the importance of an area by measuring how much flow passes through it, and how concentrated that flow is. The results can be used to identify important pinch points where movements are predicted to concentrate, or diffuse intact areas that allow for more random movements.

Some elements of Nature’s Network, such as the Terrestrial and Wetland Core Network, represent a regional plan for conserving wetland and terrestrial biodiversity. Other components, such as Habitats for Imperiled Species and Marsh Migration Zones, can be used as inputs for creating conservation plans at the local, state or regional scales.

The developers have compiled testimonials from Nature's Network users.

The Conservation Assessment & Prioritization System (CAPS) is an approach to prioritizing land for conservation based on the assessment of the ecological integrity for various natural communities (e.g. forests, headwater streams). Several metrics are applied to the landscape and then integrated in weighted linear combinations to create models for predicting ecological integrity. This process results in an Index of Ecological Integrity (IEI) for each point in the landscape based on models constructed separately for each ecological community.

CAPS takes a coarse filter approach by looking at ecosystems and ecosystem integrity, without focusing on individual species. There are several versions of MassCAPS outputs, all requiring GIS capabilities. CAPS is an assessment approach that yields data (e.g. IEI) that can be used for conservation planning, but is not itself a plan. Elements of CAPS analyses have been used in BioMap2, Designing Sustainable Landscapes (DSL) Nature’s Network, and Resilient & Connected Landscapes.

In addition to the Massachusetts CAPS assessment, UMass Amherst has produced a regional version of CAPS for the 13 northeast states as part of the Designing Sustainable Landscapes (DSL) project. MassCAPS is based on data only for Massachusetts, while DSL is based on data for 13 states, so the DSL version will be more correct near Massachusetts state borders and provides regional context—for instance regional IEI is scaled across all states in the region. MassCAPS is based on generally higher-quality data, including land cover, roofprints, traffic rates, soils, and the digital elevation model, while DSL uses data that are regionally-available, often of lower quality. MassCAPS also has several metrics not available in the DSL version: hydrologic alterations, nitrogen and phosphorus enrichment, salt marsh ditching, beach off road vehicles, beach pedestrians, coastal hardened structures, and boat traffic.

While MassCAPS does not explicitly focus on climate adaptation, areas with high IEI scores tend to be large, well-connected areas buffered from human activities, where natural processes are likely to remain intact over time. Within intact areas, natural systems are more likely to be resistant and resilient to impacts - from both humans and climate change. Areas of high IEI are likely to provide a diversity of niches and migration pathways important for maintaining biodiversity as climate change shifts species distributions over time.

The purpose of the Massachusetts Climate Action Tool (CAT) is to present research-based information about climate change impacts and the vulnerabilities of various fish, wildlife and habitat, and promote adaptation actions that can be taken at a local level. This information is paired with a map viewer to access online GIS data that was selected or synthesized to understand and respond to conservation challenges posed by climate change. The tool contains approximately 200 GIS layers as well as a wealth of information on climate-related stressors affecting Massachusetts, vulnerability assessments for over 60 species or groups of species, and a substantial list of adaptation actions ranging from forest management and land preservation to culvert replacement and dam removal.

The CAT was designed for users with limited mapping capacity, and features maps that incorporate BioMap2 and the CAPS (Conservation Assessment & Prioritization System) Index of Ecological Integrity (IEI), DSL (Designing Sustainable Landscapes) Conductance, as well as other spatial data. Species profiles include spatial data showing the current geographic distribution or habitat suitability for the species and, in many cases, projections for the future habitat suitability accounting for climate change. Spatial data can be explored using a web browser, but cannot be uploaded to or downloaded from the spatial data viewer, which includes links to data sources and additional information.

Beginning in 2000, the Landscape Ecology Lab at UMass Amherst has used landscape-scale modeling to produce data to support conservation decision-making. Since 2010, the lab has provided conservation planning data and products covering 13 states in the Northeast and Mid-Atlantic, in a project called Designing Sustainable Landscapes (DSL). The DSL approach follows a logical sequence from data generation and compilation, to assessment and modeling, to conservation design. DSL models provide much of the content of Connect the Connecticut, and Nature’s Network, both developed in collaboration with the U.S. Fish and Wildlife Service, state wildlife agencies, and conservation NGOs. DSL involves two major processes:

1. Characterization involves the compilation, correction, and generation of data for use in landscape modeling. Examples include the developed land uses, ecological communities, ecological settings variables, and climate data. These data are used as inputs for landscape assessments, although they can be useful on their own for conservation decision-making.

2. Assessment is the process of integrating data and using models to make landscape predictions. Examples include the use of CAPS (Conservation Assessment & Prioritization System) to assess the ecological integrity of ecological communities, an evaluation of regional connectivity, use of the SPRAWL model to assess risk of development, and the modeling of climate niche and landscape capability for representative wildlife species or species at risk. Incorporation of climate data into the models facilitates predictions of future ecological integrity, connectivity, landscape capability and potential habitat refugia.

The DSL data products likely to be most useful for land protection and stewardship are:

• Regional CAPS Index of Ecological Integrity (IEI)

• Conductance index (an measure of the importance of land for regional-scale connectivity)

• Integrated probability of development

• Focus species models

• Conservation design elements from Nature’s Network

Some of the DSL data has been clipped to state boundaries.

The Adaptation Workbook is a structured process to consider the potential effects of climate change, and to design land management and conservation actions that can help prepare for changing conditions. The process is completely flexible to accommodate a wide variety of geographic locations, ownership types, ecosystems, land uses, management goals, and project sizes. The Adaptation Workbook walks users through a process for considering climate change impacts and identifying management actions that could be taken to directly adapt to climate change. This resource incorporates rigorous science, with information and “menus” of actions for forests (including urban forests) and agricultural lands. The output of the process is a comprehensive climate adaptation plan. This application is most useful for users with clear management goals and knowledge about their property or ecosystem of interest.

The developers have produced two quick guides (see Products section above) as entry points to Adaptation Workbook and the climate adaptation planning process, and for facilitating climate adaptation project discussions between those already familiar with the fuller, original version.

There are a large number of case studies that show how Adaptation Workbook has been used by forest conservation practitioners.
