The Bureau of Land Management's National Invasive Species Information Management System (NISIMS) is designed to collect field data and store it in a standard database to allow for data sharing and reporting at the local, state and national levels. At this time, the system reports and tracks weed infestations only, Future versions of the system will report and track infestations by all taxa including weeds, birds, fish, and algae. The system also reports and tracks treatments of these invasive weed species infestations on public lands. The tools are based on the use of the BLM system of Enterprise Geographic Information System (EGIS) Architecture approved nationally in 2003. It also depends on the Geospatial Services Strategic Plan approved nationally by BLM management in 2008. It is the first BLM system with seamless tools to collect scientific data in remote locations throughout all BLM lands and to feed that data regularly into national, official BLM geospatial database. Though the infestation data included here represents a snapshot of actual infestations of the individual species, it doesn't represent the total infestations of the particular species. Only a fraction of the lands the BLM administers has been inventoried, and not all of that data has been brought into NISIMS.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 101,203 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.


The table below shows only published versions of the resource that are publicly accessible.
