Nature-Based Solutions Tools Search

This database contains over 400 tools and resources that can help guide practitioners at various stages of the nature-based solutions project cycle. Use the filters to identify the tools and resources most useful to you.

You can filter the full list by the habitat type you’re working in, the nature-based solutions strategy you want to use, the project phase you are looking for help with, or the type of tool/resource you’re looking for.

The tools and resources shown here were gathered through a robust search of both federal and non-federal sources. We recognize that this library will never be completely comprehensive, but if you know of an important missing tool or resource, please email nesp@duke.edu.

Developed for stormwater and floodplain managers, as well as land use planners, this interactive website incorporates tools and methods to derive critical coastal water-level thresholds, as well as assess the potential impacts of exceeding those thresholds on stormwater infrastructure. Managers can take various actions to address the issue, and this guide introduces planning, policy, on-the-ground, and funding options.

Relevant phase:

This tool lets users project the carbon reduction potential of different actions from the COMET - Planner tool (WRG048) ad extrapolate up to the national level.

Climate Resilience Evaluation and Awareness Tool (CREAT) is a tool that assists water sector utilities in assessing climate-related risks to utility assets and operations. Throughout CREAT’s five modules, users consider climate impacts and identify adaptation options to increase resilience. Modules include: climate awareness, scenario development, consequences and assets, daptation planning, and risk assessment. 

Identifies geographic areas within which seeds and native plants can be transferred based on current and future climate data.

This storymap provides a brief introduction to the development and potential uses of USGS' CoSMos tool, which makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales.

Relevant phase:

This tool can be used to estimate the greenhouse gas reduction and carbon sequestration potential of a landowners farm or ranch. It could be a useful tool for quantifying the value of specific NBS strategies.

This tool can be used to estimate the greenhouse gas reduction and carbon sequestration potential of different conservation practices based off county-level geographic data. It could be useful for quantifying the value of specifc NBS strategies.

EnviroAtlas data and resources can be used to inform a range of projects, from regional to local scales. This easy to use, interactive mapping application does not require any GIS skills to use and provides ready access to 536 map layers likegreen space per capita, mammal species richness or percent developed area and multiple analysis tools. EPA uses this tool for uses like project implementation (e.g. permitting) and designing targeted outreach strategies, but the site includes a repository of diverse ways this tool can be used in advancing all types of environmental work. 

Tool to assess the probability of erosion after a prescribed burn in sagebrush ecosystems, based on climate, soil, vegetation, slope, and fire characteristics.

Relevant phase:

FACT (Financing Alternatives Comparison Tool) is an easy-to-use financial analysis tool that
compares the costs associated with various financing options for water infrastructure and
water quality projects. There are two versions of the tool - FACT standard, which provides comprehensive analyses, and FACT Lite, which offers simplified analyses for high-level cost comparisons.

Relevant phase:

FVS is a tool commonly used in forestry by land managers. FVS can provide useful insight into how to thin for various goals, especially the Fire and Fuels Extension.

NBS Strategies:

*Includes: Stormwater Management Model (SWMM), National Stormwater Counter (SMC), Green Infrastructure Wizard (GiWizard), Watershed Management Optimization Tool (WMOST), Visualizing Ecosystems for Land Management Asessment (VELMA) Model, Green Infrastructure Flexible Model (GIFMod), Community-enabled Lifecycle Analysis of Stormwater Infastructure Costs (CLASIC) Tool, and the Integrated Decision Support Tool (i-DST)

Software that provides tree benefit estimation science through various tools and support.

NBS Strategies:

Web-based application designed to help land managers with fuel treatment planning and analysis.

NBS Strategies:

Provides agency leaders with vegetation and wildland fire/fuel information to enable strategic fire planning.

NBS Strategies:

The Long-Term Stewardship Calculator estimates long-term stewardship costs and the amount that should be set aside to provide a secure source of future funding.

Relevant phase:

NCEI’s Regional Climate Services provides access to climate information, products, and other resources for specific regions across the United States. These services provide tailored, comprehensive support to help address the unique challenges and vulnerabilities created by regional weather and climate conditions. Notable resources for Nature based Solutions include coastal surface analysis products, coastal ecosystem maps, and coastal monitoring and indicator products. 

Relevant phase:

Part of NOAA’s Digital Coast toolbox, SLAMM helps predict where marshes will migrate to under threat from rising seas. The model contains helpful inputs including dike locations, accretion rates, and erosion rates. An explainer document is available.

NBS Strategies:

This webpage links to several seed mix calculators that can be used for pollinators, native plant restoration, and to calculate seeding rate.

Relevant phase:

The SHORE-BET: Marsh Restoration Community Benefit Calculator calculates the economic value of select key coastal community benefits to be gained by using living shoreline techniques that restore marshes. This tool helps to account for these ecosystem services so that coastal communities can be better informed when making decisions impacting their environment, economy, and overall quality of life.
