Oregon iMapInvasives Resources

iMapInvasives is an international GIS-based online platform for collecting, managing, and sharing invasive species data. Oregon iMapInvasives is available for free to all resource managers and interested citizens. The iMapInvasives network is a consortium of programs in several US states and a Canadian province.  Here in Oregon, Cascade Pacific has partnered with Portland State University to fiscally sponsor the Oregon iMapInvasives. 

Oregon adopted the iMapInvasives program to support early detection and rapid response efforts throughout the state and to provide a standardized, accessible site for sharing plant and animal sightings amongst the many groups that collect invasive species data. The Oregon iMap program is supported by annual subscriptions from partner organizations. As part of your subscription you will receive a copy of the statewide iMapInvasives dataset, and ensure that the iMap service remains available to all Oregonians.

Please contact iMap Site Manager Lindsey Wise at PSU for questions about how to use iMap and WIN Coordinator Vern Holm for questions about how to apply for a subscription. To learn more about iMap Resources click on the links below.

What is an Invasive Plant?

Invasive plants reproduce and grow so vigorously they displace desired vegetation and create large, single species stands or monocultures, such as this Scotch broom (left). These plants spread vigorously because they have no natural enemies (i.e., insects, animals, disease) in their introduced environments to control their spread.


Why Do We Care About Invasives?

Invasive plants are a major threat to native ecosystems. They replace native vegetation, destroy wildlife habitat, displace threatened and endangered species, increase wildfire fuels, negatively impact riparian areas and watersheds, and decrease overall biological diversity.  Russian thistle (right) is a highly aggressive invasive species that displaces native vegetation.
