Disclaimer: While I-Rank information is available over NatureServe Explorer, NatureServe is not actively developing or maintaining these data. Species with I-RANKs do not represent a random sample of species exotic in the United States; available assessments may be biased toward those species with higher-than-average impact.

I-Rank: Low
Rounded I-Rank: Low
I-Rank Reasons Summary: This naturalized ornamental plant is reproductively aggressive, but has no reported ecological impacts. It is found in the wild in California and Colorado, and is fairly hard to control.
Subrank I - Ecological Impact: Insignificant
Subrank II - Current Distribution/Abundance: Medium
Subrank III - Trend in Distribution/Abundance: Low
Subrank IV - Management Difficulty: Medium
I-Rank Review Date: 29Feb2004
Evaluator: Lu, S.
Native anywhere in the U.S?
Native Range: Native to Europe (Elpel, no date; CWMA 1999; Dave's Garden 2004; LeCain and Sheley 2002).

Screening Questions

S-1. Established outside cultivation as a non-native? YES
Comments: This species is a non-native that is established outside of cultivation (Kartesz 1999).

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Naturalized in the wild in California (CalFlora 2004) and widely established on the western slope of Colorado (CWMA 1999).

Subrank I - Ecological Impact: Insignificant

1. Impact on Ecosystem Processes and System-wide Parameters:Low significance/Insignificant
Comments: No reported impacts. However, there are reports that this plant may be potentially invasive (UW Herbarium, no date), and may be a noxious weed or invasive (Dave's Garden 2004).

2. Impact on Ecological Community Structure:Insignificant
Comments: No impact reported.

3. Impact on Ecological Community Composition:Low significance
Comments: Attracts insects, especially ladybugs (Dave's Garden 2004).

4. Impact on Individual Native Plant or Animal Species:Insignificant
Comments: No impact reported.

5. Conservation Significance of the Communities and Native Species Threatened:Insignificant
Comments: No impact reported.

Subrank II. Current Distribution and Abundance: Medium

6. Current Range Size in Nation:High significance
Comments: Established in more than 40 states (Kartesz 1999). Not established in southeastern states - Florida, Georgia, South Carolina, Alabama, and Texas. This plant is now widespread from coast to coast across most northern states and Canadian provinces (Elpel, no date). Naturalized in the wild in California (CalFlora 2004) and widely established on the western slope of Colorado (CWMA 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Insignificant
Comments: Particularly aggressive when growing along irrigation ditches where it can restrict water flow (CWMA 1999). In California, found in disturbed urban areas (Hickman 1993). In Colorado, found commonly along fencerows in the valleys on the western slope (Weber and Wittmann 1996).

8. Proportion of Nation's Biogeographic Units Invaded:High significance
Comments: In at least 35 ecoregions(Inference using data from Kartesz 1999 and TNC Ecoregion 2001 map).

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Low significance
Comments: Particularly aggressive when growing along irrigation ditches where it can restrict water flow (CWMA 1999). Especially favors the disturbed soils along ditch banks (Elpel, no date). Found in fields, roadsides, and disturbed areas (UW Herbarium, no date). Occurs in wetlands somewhere other than California (CalFlora 2004). In California, found in disturbed urban areas (Hickman 1993). In Colorado, found commonly along fencerows in the valleys of the western slope (Weber and Wittmann 1996).

Subrank III. Trend in Distribution and Abundance: Low

10. Current Trend in Total Range within Nation:Low significance
Comments: No reports of expansion in total range.

11. Proportion of Potential Range Currently Occupied:Unknown
Comments: Hardy from Zones 4-8 (PlantFinder, no date). See map for predicted potential range in Montana (LeCain adn Sheley 2002).

12. Long-distance Dispersal Potential within Nation:Insignificant
Comments: Water spreads the seeds for miles downstream and still sold as seed (Elpel, no date).

13. Local Range Expansion or Change in Abundance:Insignificant
Comments: No reports of expansion in local range.

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Low significance
Comments: Found in fields, roadsides, and disturbed areas (UW Herbarium, no date). Occurs in wetlands somewhere other than California (CalFlora 2004). Particularly aggressive when growing along irrigation ditches where it can restrict water flow (CWMA 1999). In California, found in disturbed urban areas (Hickman 1993). In Colorado, found commonly along fencerows in the valleys of the western slope (Weber and Wittmann 1996).

15. Similar Habitats Invaded Elsewhere:High/Low significance
Comments: Also established in Canada (Kartesz 1999).

16. Reproductive Characteristics:High significance
Comments: Reproduces by both seed and rootstock (CWMA 1999). It has an extensive spreading root system and profuse seed production. It can regenerate from root fragments. (Elpel, no date).

Subrank IV. General Management Difficulty: Medium

17. General Management Difficulty:High/Moderate significance
Comments: Difficult to control (CWMA 1999). Mechanical or cultivation is not effective, due to regrowth from root fragments. Grazing with sheep and goats seems to be very effective. Herbicides can relatively easily control this plant, except in cases where the weed is intermixed with other desirable plant species. Also when using herbicides, must be careful to avoid contaminating the water near ditch banks and creeks. (Elpel, no date; LeCain and Sheley 2002)

18. Minimum Time Commitment:Moderate significance
Comments: Weed patches of this perennial must be monitored and retreated to kill any tansy that regenerates from the roots (Elpel, no date).

19. Impacts of Management on Native Species:Low significance
Comments: Herbicides can relatively easily control this plant, except in cases where the weed is intermixed with desirable native plant species.

20. Accessibility of Invaded Areas:Low significance
Comments: Found in irrigation ditches (CWMA 1999). Found in fields, roadsides, and disturbed areas (UW Herbarium, no date). Occurs in wetlands somewhere other than California (CalFlora 2004). In California, found in disturbed urban areas (Hickman 1993). In Colorado, found commonly along fencerows in the valleys of the western slope (Weber and Wittmann 1996).
