This form provides a web-based query interface to habitat descriptions summarized from the Habitat Structure Assessment1 data collected at each MAPS station. This description includes USGS - NPS National Vegetation Classification Standard2 (NVCS) classifications of the dominant and subdominant habitats3 at each MAPS station, where available.

Please select either a Region, State/Province, Location Code, or Station Code below:

1  For more information on the Habitat Structure Assessment protocol, please review the Habitat Structure Assessment Manual. Additional Habitat Structure Assessment forms, figures, and appendices may be viewed or downloaded from The Institute for Bird Populations' MAPS Materials web page.
2  Further information on the USGS - NPS National Vegetation Classification Standard (NVCS) is available on the USGS - NPS Vegetation Mapping Program home page.
3  MAPS stations typically have one, two, or three habitat types; rarely there may be as many as five habitat types at a station. The dominant habitat is the one occupying the largest proportion of the station (regardless of where nets are located). The subdominant habitat is the one occupying the second largest proportion of the station.
4  Region codes identify the MAPS Region in which the station is located: AK = Alaska Region, B&AC = Boreal & Arctic Canada Region, NW = Northwest Region, SW = Southwest Region, NC = North-central Region, SC = South-central Region, NE = Northeast Region, SE = Southeast Region. See the NBII MAPS Home Page for a map of the Regions.
5  Location codes are unique four-character codes identifying a national forest, national park, military installation, or other location where a single station or a cluster of stations is located and is run by a single operator (often with many assistants).
6  Station codes are four-character codes used to identify stations and are unique within a location. A station is defined as a discrete study area consisting of a fixed number of net sites.
