U.S. Invasive Species Impact Rank (I-Rank)
Help
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/Insignificant
Rounded I-Rank: Low
I-Rank Reasons Summary: Although this species is reproductively aggressive and is often planted for land management purposes, it rarely occurs in or impacts conservation areas. This species is mostly a problem in wet meadows. The only native species habitat that it occurs in is waterways. It has no reported ecological impact and a low current range.
Subrank I - Ecological Impact: Insignificant
Subrank II - Current Distribution/Abundance: Low
Subrank III - Trend in Distribution/Abundance: Medium/Low
Subrank IV - Management Difficulty: Unknown
I-Rank Review Date: 15Jan2004
Evaluator: Lu, S.
Native anywhere in the U.S?
Native Range: Eurasia (Welsh et al. 1987; Bailey and Bailey, 1976).

Screening Questions

S-1. Established outside cultivation as a non-native? YES
Comments: Established outside of cultivation as a non-native in the U.S. (Kartesz, 1999).

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Reported as invasive in Scotts Bluff National Monument, Nebraska (PCA 2003), which is pretty degraded but still has some conservation value as it contains plains, bluffs, and mixed-grass prairies (NPS, no date). Scotts Bluff NM is also native species habitat for four species with federal USESA status: northern bald eagle, whooping crane, peregrine falcon, and the burrowing owl (candidate).

Subrank I - Ecological Impact: Insignificant

1. Impact on Ecosystem Processes and System-wide Parameters:Insignificant
Comments: Does not fix nitrogen. Is not allelopathic. (USDA NRCS, no date). This species has a high fire tolerance, but the ecological consequences of that characteristic are unclear.

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

3. Impact on Ecological Community Composition:Insignificant
Comments: No impacts reported.

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

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

Subrank II. Current Distribution and Abundance: Low

6. Current Range Size in Nation:Moderate significance
Comments: Currently established in 9 states - Idaho, Kentucky, Montana, North Dakota, Nebraska, South Dakota, Utah, Washington, and Wyoming. (Kartesz 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Insignificant
Comments: Reported as invasive in Scotts Bluff National Monument, Nebraska (PCA 2003). Reported as invasive in Wyoming (Hartman and Nelson, 2000).

8. Proportion of Nation's Biogeographic Units Invaded:Medium/Low significance
Comments: Occurs in at least 5 ecoregions and up to 19 ecoregions (Inference using data from Kartesz 1999 and TNC Ecoregion 2001 map).

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Insignificant
Comments: Occurs mainly in non-conservation areas, such as roadsides, irrigated pastures (Welsh et al. 1987), and meadows, but also occurs along waterways (Ernst Conservation Seeds, 2003).

Subrank III. Trend in Distribution and Abundance: Medium/Low

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

11. Proportion of Potential Range Currently Occupied:Unknown
Comments: Potential range not known.

12. Long-distance Dispersal Potential within Nation:High significance
Comments: Human long-distance dispersal frequent. Planted as a streambank stabilizer in western Nevada (UN-Reno, 1995), for pasture in western Montana (Goodwin and Sheley, 2003), and for stormwater management in Illinois (LITH 2002).

13. Local Range Expansion or Change in Abundance:Low significance
Comments: Reported as invasive in Scotts Bluff National Monument, Nebraska (PCA 2003) and in Wyoming (Hartman and Nelson, 2000) may indicate some local range expansion or increase in abundance, but only is a small portion of all populations of this species in the US.

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Insignificant
Comments: No reports of being able to spread into conservation areas on its own.

15. Similar Habitats Invaded Elsewhere:High/Low significance
Comments: Established as a non-native in Canada (Kartesz 1999)

16. Reproductive Characteristics:High significance
Comments: Rapid growth rate, high seed abundance, rapid vegetative spread rate, rhizomatous growth form, moderate seed spread rate (USDA NRCS, no date).

Subrank IV. General Management Difficulty: Unknown

17. General Management Difficulty:Unknown
Comments: Has low resprouting ability (USDA NRCS, no date).

18. Minimum Time Commitment:Unknown

19. Impacts of Management on Native Species:Unknown

20. Accessibility of Invaded Areas:Unknown
