Accuracy assessment and metadata are incomplete but it does include fire and agriculture through 2014 • We are using it for predictive modelling (Ecology and Zoology), as a background map layer, and as the basis for other project products, including a Human Disturbance index • Currently, land cover mapping focuses on specific land cover classes such as Russian olive and whitebark pine, and on the production of ancillary products for modelling and analysis

Russian olive 2013Russian olive 2013 • Classification accuracies ranging from 93.6% to 99.07% • Overall, 17,694 acres along eastern Montana’s large rivers were infested by Russian Olive in 2013 • Bighorn River is most affected, with over 3% of its valley bottom covered by Russian Olive. • The Musselshell, Clark Fork of the Yellowstone, Marias, Powder and Yellowstone rivers have over 1% of their flood plain covered by Russian Olive. • The Milk River has less than 1%, but it has the third largest acreage of infestation (2,038 acres). • Based on our predictive models, a total of 310,664 acres have a high probability of Russian Olive infestation in the future as cottonwoods die out

Editor's Notes

  • Document the distribution, status, community composition and successional dynamics of Montana’s ecological systems and communities (focusing on systems and communities of concern)
  • MTNHP started the Wetland and Riparian Mapping Center in 2006 with initial funding from an EPA Wetland Program Development Grant in cooperation with DEQ. We currently have four GIS specialists creating the mapping. We are fortunate to be part of both the University of Montana and the Montana State Library, so we have the benefit of having access to the necessary infrastructure and software needed to map on a large scale. Since 2006, we’ve created mapping with funding from many federal, state, and Tribal partners.
  • Since 2006, we’ve mapped over 2.5 million acres of wetlands and riparian areas. Based on current mapping progress, over 70% of Montana will have digital mapping based on 2005 imagery or newer within the next 3 years.
  • But we still have a ways to go. Our goal is to update the mapping for the entire state.
    The blue areas represent the areas with historic NWI mapping and the red areas represent those areas without mapping.
    Why Update the Mapping?
    Historic mapping underestimates areal extent of wetlands
    Many wetland features were not mapped
    Riparian areas were not mapped
    Some of these quads may contain as few as 5 wetland features
    Availability of digital mapping
    Robust ancillary datasets
    Rigorous data standards
    Increased ability to delineate and classify accurately
    Land use changes
