Terrestrial Invasive Plants
The CMP recognizes that terrestrial invasive plants are one of the largest threats to ecological integrity in the Crown.
The CMP is working with partners to coordinate and align data and management for some of the region's top terrestrial invasibe plants. The CMP aims to support a region-wide strategy that synthesizes challenges and successes, early invaders, treatment strategies and jurisdictional mandates.
In 2005 terrestrial invasive species was the CMP Forum topic. The Invasive Plants of the Crown of the Continent field guide was a deliverable that came out of the 2005 Forum and has been shared widely throughout the Crown.
In 2015, the Crown Managers Partnership held another forum on terrestrial invasive plants titled "People, Climate and Terrestrial Invasive Species: Taking Collective Action in the Crown of the Continent."
Through a variety of data captures, survey and analysis, the CMP and expert speakers provided forum participants with a snapshot of the current status and likely future of invasive plants, along with current priorities and efforts of management agencies throughout the Crown.
Currently, there is a working group coordinating the following action themes that emerged from the 2015 Forum:
survey and monitoring;
external communication and awareness;
common management approaches; and
vectors and corridors.
Current and future habitat suitability of orange hawkweed. Modelled using species presence data collected throughout the Crown; associating it with climate conditions at each of the location the species was detected. Future suitable habitat was created by extrapolating the species/climate relationship using the a climate scenario with moderate emissions. Habitat suitability does not necessarily mean species presence; rather it indicates that climatic conditions are potentially suitable for the species in the areas shown in the map. The species might not be present on some of the suitable area due to distance to seed pool, competition, or other biological mechanisms.
