Welcome

This Fish Habitat Decision Support tool provides resource managers and the general public access to data, models, and prioritization tools for use with multiple fish habitat assessments performed for specific regions across the United States.

Three main analytical tools (visualization, ranking, and futuring) are combined with intuitive basemaps and mapping features to allow users to explore the details of the assessments and perform subsequent analyses.

This tool was developed with funding from the United States Fish and Wildlife Service and the Midwest Fish Habitat Partnerships. Additional data and models were developed through funding and coordination by the North Atlantic LCC, the Atlantic Coastal Fish Habitat Partnership, and The Nature Conservancy.

About the Visualization Tool

This Visualization Tool is designed to generate thematic maps based on a variety of landscape, stressor, and natural quality attributes related to fish habitat. There is data related to landscape characteristics such as percent forest and dam density. There is also data related to models for specific fish species, fish guilds, (groupings of similar species), and indices. For more information on specific species, guilds, and indices, you can access the reports here. The data supporting this visualization has been collected and modeled for six regional organizations. These are: Fishers and Farmers Partnership, Driftless Area Restoration Effort (DARE), Great Lakes Basin Fish Habitat Partnership (FHP), Great Plains FHP, Ohio River Basin FHP, and the Midwest Glacial Lakes Partnership. For more information on the datasets used in this analysis, please visit the Midwest Fish Habitat Partnership website at http://www.midwestfishhabitats.org/.

About the Ranking Tool

This Ranking Tool provides the opportunity to intersect and weight datasets based on a preference or an individual’s criteria. This analysis is made available through an interface of selecting data, applying weight(s), and running a ranking algorithm that produces a new criteria-based ranked dataset at the catchment level. There is data related to landscape characteristics such as percent forest and dam density. There is also data related to models for specific fish species, fish guilds, (groupings of similar species), and indices. For more information on specific species, guilds, and indices, you can access the reports here. Please see the Help tab for detailed instructions on how to produce your own ranking datasets. For more information, please visit the Midwest Fish Habitat Partnership website at http://www.midwestfishhabitats.org/.

Ranking Instructions

Please use the following general workflow to create ranking scenarios:

1 —Click on the Setup tab under the Ranking Tool to define the parameters of your ranking request.

Ranking

2 —Enter a Ranking Name up to 25 characters. This will help you identify the results of your ranking in the Results table of contents.

3 —Select a Scale and Geography of Ranking. There are two choices:

  • Watershed – rank catchments in a specific HUC8 watershed using a wide variety of natural and socioeconomic variables
  • Lake – rank lakes in a specific HUC8 watershed using a wide variety of model-specific variables. This is only available for the Midwest Glacial Lakes Partnership area.

4 —Click on the button to select a HUC8 watershed as your Area of Interest on the map interface.

5 —Depending on which watershed you select, you will now have to select a Model of Interest from the next dropdown list. These are either species-specific models or landscape variables.

6 —Finally, select the desired attribute from the Model Data of Interest dropdown list. You can reset the form using the Reset button.

7 —Press Add Variable to add the selected variable to the list at the bottom of the form.

Ranking

8 —You may assign a Weight to the selected variable. This is the relative importance of the variable in your ranking model. You may select values from 5-100. If you add multiple variables to your ranking model and set the weight the same for each, they will contribute equally to the final ranking score.

9 —The Ranking Tool assumes that high values (e.g. percent forest) are good unless you tell it otherwise. If high values for the variable you select are bad (e.g. population density) then check the Inverse check box and those variables will contribute more for lower values.

10 —Select more variables and add them to the list, adjusting their weights as desired. You may add up to five variables per ranking request.

Ranking

11 —When you have the desired mix of variables, press the Rank button to see the results of your ranking request. Note that the ranking calculations may take up to two minutes depending on the complexity of your request.

Note: The futuring tool is designed to provide guidance only. All resulting changes are based on the underlying model, which has inherent limitations. To read more about the details and limitations of the underlying models, please visit www.fishhabitattool.org/info.html.

About the Futuring Tool

This Futuring Tool provides the opportunity to change the values of selected variables for up to five catchments within a single HUC8 watershed, accumulate the updated values downstream, and use the new watershed-level values to run a R model to produce a new score for probability of presence for the model in question. This tool is currently available to be used for five models in the Great Lakes Basin FHP and select areas in the Ohio River Basin FHP. Please see the Help tab for detailed instructions on how to produce your own futuring datasets. For more information on the data used and the overall process, please visit the Midwest Fish Habitat Partnership website at http://www.midwestfishhabitats.org/.

Futuring Instructions

Note: The futuring tool is designed to provide guidance only. All resulting changes are based on the underlying model, which has inherent limitations. To read more about the details and limitations of the underlying models, please visit www.fishhabitattool.org/info.html.

Please use the following general workflow to create futuring scenarios:

1 —Click on the Setup tab under the Futuring Tool to define the parameters of your futuring request.

Futuring

2 —Enter a Futuring Name up to 25 characters. This will help you identify the results of your futuring in the Results table of contents.

3 —Select a Model of Interest. There are two types of choices:

  • Great Lakes Basin – Brook Trut, Walleye, Large River Species, Coldwater Species, Lithophilic Species Richness
  • Ohio River Basin – Macroinvertebrate Bioassessment Index, Index of Biotic Integrity (fish)

4 —Click on the button to select a catchment to add to the analysis and update values for.

5 —Depending on which model you selected, you will now have to select your Data of Interest from the next dropdown list. Note: for the Index of Biotic Integrity model, the crops variable is a local variable, and therefore any local changes will only cause changes in predictions within that local watershed. The same is true for the road length variable for the Lithophillic Species Richness model.

6 —Press Add Catchment to add the selected catchment to the list at the bottom of the form.

Futuring

7 —You may update the value of the selected variable. This value will be used to accumulate network values downstream. The resulting updated values will be fed into the model to produce updated probability of presence.

8 —Using the Catchment Selector, select more catchments and add them to the list, adjusting their values as desired. You may add up to five catchments per futuring request.

Futuring

9 —When you have the desired mix of catchments and variables, press the Future button to see the results of your futuring request. Note that the futuring calculations may take up to two minutes depending on the complexity of your request. Please note that not all futuring scenarios will show significant change. Depending on the model, even major local changes will have no impact on downstream catchments.

Working with Your Futuring Layers

Once you have performed a futuring, you can control and export the results.
