The module provides access to current data for your specific site. This can help determine if you are providing the habitat needed for key species. Habitat information and data collected in the app can be used to develop goals, guide management actions, and develop monitoring plans.

The following videos will show you how to use the LandPKS Habitat Module to learn about wildlife habitats that might or could exist on your land.

Note: these training videos are based on version 3.6.6 of the LandPKS mobile app.



What is a Habitat?

The term “Habitat” refers to the natural home or environment of a plant, animal, or other organism. The existence of terrestrial plant and animal habitats depends on both the land’s potential and how it is managed. LandPKS provides information on potential habitats by integrating species distribution maps with soil information (based on the types of soil that have been mapped at your location). The app also allows you to then identify the soil. Links to “Ecological Site Descriptions” (ESDs) through EDIT provide information on the types of vegetation that could occur on that soil.

ESDs also provide information on the types of management and restoration actions that may result in transitions among different types of vegetation. A wide variety of management strategies can be used to promote these transitions.

A common misconception is that creating wildlife habitat just means grazing a pasture less than one otherwise would in order to leave more grass behind. Through planning and management to control grazing intensity across space and time, heterogeneity of vegetation can be created even within relatively homogenous landscapes. By creating a patchwork of habitat conditions, land can provide habitat for many different plant and animal species.

Who is the LandPKS Habitat Module for?

The LandPKS Habitat Module is for ranchers, farmers, wildlife conservationists, homeowners, educators, and park and other land managers who are interested in preserving and fostering wildlife habitats on their land. The Habitat Module can be used for both planning and educational purposes, on ranches and in schools, in suburban neighborhoods and on wildlife preserves.

What does the LandPKS Habitat Module do?

The LandPKS Habitat Module currently includes a selection of 22 plants, mammals, birds, reptiles, amphibians and insects that occur in North America, with an emphasis on those that occur in the Great Plains and Great Basin. The Habitat Module contains line drawings of habitats, written descriptions, and a table of habitat characteristics for each species. The habitat drawings are not intended to show all variability within a landscape that a species needs. Rather, the representations depict an “ideal” habitat or critical habitat type (e.g. nesting). See the species factsheets for more information about habitat characteristics. Following collection of soil or vegetation data at any location, the app will display a summary of data for the corresponding habitat characteristic needed by the species.

The information in the LandPKS Habitat Module is designed to be used, together with other information sources, to help define suitable habitat. It is not predictive and is not intended for regulatory purposes.

The LandPKS Habitat Module currently includes only a subset of species that occur in North America.

Habitat illlustration: midgrass prairie

Habitat illlustration: sagebrush shrubland

Habitat illustration: shortgrass prairie

The habitat illustrations for each species in the app depict “ideal” habitats or limiting habitats (i.e. nesting), rather than depicting all the habitat needs. Above are some examples of illustrations within the app. Top image: Mid-grass prairie; Middle image: Sagebrush shrublands; Bottom image: Shortgrass prairie.


Our Factsheets provide information that can be used to help identify plant and animal species and manage land to improve habitat conditions. The LandPKS Habitat Factsheets are available for download from within the mobile app and from the LandPKS Knowledge Hub.  Each species  factsheet provides a photograph and description of the species, management information, and facts about habitat needs across the species range. The species description, habitat requirements, distribution and management information are written for land managers, and are of value to anyone in habitat conservation. The factsheets also provide ideas for how to contribute in meaningful ways to the quantity and quality of suitable habitat available for a species.

Click to read the full 2016 report “Unlocking the Sustainable Potential of Land Resources: Evaluation Systems, Strategies, and Tools,” written by the International Resource Panel. The tools and resources below are referred to in the report. Please refer to the available links for additional information. We have included hyperlinks for bibliography entries from the IRP report whenever possible.


  • The Food and Agriculture Organization of the United Nations provides a tremendous and constantly increasing amount of tools, data, information and knowledge relevant to sustainably increasing food production. The Land Resources Planning Toolbox provides direct access to a wide variety of useful tools.
  • The International Soil Reference and Information Centre World Soil Information’s website features various tools and data to provide global soil information and currently serves as the primary global repository for soil information. ISRIC uses machine learning methods to create SoilGrids, a digital global soil mapping system whose prediction models use over 230,000 soil profile observations.
  • This website is continuously updated with land evaluation resources and examples of how land evaluation has been successfully used around the world.
  • Landon (2014) provides a concise, practical reference for much of the technical knowledge necessary to implement land evaluation and management.
  • This web portal provides access to a wide variety of tools, including automated sampling design, data analysis and reporting, and simple image-analysis tools that anyone can learn in under an hour. It also includes a Wiki, which, among other things, helps decide what remote sensing imagery is most appropriate based on objectives.
  • The ability to search for articles based on where the research was completed, rather than where the author’s office has been, is nearly impossible in Google Scholar and other bibliographic search engines. JournalMap allows users to search for articles based on location, as well as the biophysical characteristics of a location. 
  • The United Nations Convention to Combat Desertification (UNCCD) Knowledge Hub contains a wealth of information about desertification, land degradation, and drought. It features a Drought Toolbox to support action on drought preparedness and a Capacity Building Marketplace for sharing knowledge and opportunities. In addition, the UNCCD Knowledge Hub contains country pages to connect individuals to local organizations and recommend tools tailored to national conditions.
  • UNEP is continuing to increase access to tools, data and knowledge resources, including through UNEPLive.
  • Global Agro-Ecological Zones: The Food and Agriculture Organization of the United Nations (FAO) and the International Institute for Applied Systems Analysis (IIASA) have developed the Agro-Ecological Zones (AEZ) methodology over the past 30 years for assessing agricultural resources and potential. GAEZ allows users to access previously-run evaluations using a geospatial interface.
  • The World Soil Archive and Catalogue provides access to soil survey reports, maps, imagery and photographs from 344 territories worldwide.
