This reference contains archived geospatial data for the survey Invasive Plant Species Inventory and Monitoring (PRIMR record FF01RTBL00-006), for the years 2004-2021. The refuge began using a GPS based survey for invasive species in 2004 using a modified version of the Montana State Survey Protocol. The survey was designed to systematical inventory and map 25 invasive plant species on the entire refuge to assess the current biological integrity of terrestrial plant communities and identify areas in need of control and management. The survey requires navigation to waypoints on a 50-meter point grid and collecting information on the presence and cover of invasive species in a 0.1 acre plot. In addition, encounters of invasive species between grid points are also mapped as pints and areas greater than 0.1 acre are mapped as a polygons. The survey provides geographic location of invasive species to focus control and management activities and the systematically sampled point grid provides important information on the level of infestation with a surveyed unit and attributes associated with invasions such as plant community, slope, aspect, proximity to roads and facilities and level of disturbance . Revisits of sites following control treatments allow comparisons to determine efficacy of treatments or potential spread of occurrences. Surveys typically occur from July to October.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The final NIOB vegetation map consists of 2,762 polygons totaling 29,081 acres (11,768 ha). Mean polygon size for vegetated types is 8.2 acres (3.32 ha). Of the total area, 20,878 acres (8,449 ha) or 72% represent natural or ruderal vegetation map classes. Agricultural vegetation, such as cultivated crops and pasture, account for approximately 3,267 acres (1,322 ha) or 11% of the total mapped area. Non-vegetated barren land is rare and only accounts for 520 acres (210 ha) or 1.8%. Open water is the most widespread land cover class with an area of approximately 4,415 acres (1,786 ha) or 15% of the total mapped area. Within the total area occupied by vegetation map classes, forest and woodland types were the most extensive (12,278 acres (4,969 ha) or 42%), followed by herbaceous types (7,021 acres (2,841 ha) or 24%), shrubland types (1,134 acres (532 ha) or 4.5%), and sparse types (265 acres (107 ha) or 0.9%).

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. A final vegetation map for TIMU was created to represent the vegetation occurring within the park during 2012. This product represents the final of four steps necessary to produce an accurate vegetation map based upon aerial photographs. This includes the determination of the community element global (CEGL) codes (2008) and acquisition of aerial imagery (2012), using the aerial imagery, with 162 ground truthing points (2014, 2015), to create a draft vegetation map, performing an accuracy assessment (2016), and then using all the available information to create a final vegetation map (2018).
