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: Medium/Low
Rounded I-Rank: Medium
I-Rank Reasons Summary: This annual weed of disturbed areas can be a serious agricultural pest but impacts on native biodiversity are probably somewhat limited. Can invade native habitats along disturbance corridors, however.
Subrank I - Ecological Impact: Low/Insignificant
Subrank II - Current Distribution/Abundance: High
Subrank III - Trend in Distribution/Abundance: Medium/Low
Subrank IV - Management Difficulty: Medium/Low
I-Rank Review Date: 10Mar2004
Evaluator: Maybury, K.
Native anywhere in the U.S?
Native Range: Central America

Screening Questions

S-1. Established outside cultivation as a non-native? YES

S-2. Present in conservation areas or other native species habitat? Yes

Subrank I - Ecological Impact: Low/Insignificant

1. Impact on Ecosystem Processes and System-wide Parameters:Low significance/Insignificant
Comments: No reports of significant impacts on abiotic ecosystem processes.

2. Impact on Ecological Community Structure:Moderate significance
Comments: Vine habit; can smother other plants.

3. Impact on Ecological Community Composition:Medium/Low significance
Comments: I found no reports of extensive monospecific stands, but probably has significant to minor impacts in some areas.

4. Impact on Individual Native Plant or Animal Species:Low significance/Insignificant
Comments: Possibly somewhat parasitic?

5. Conservation Significance of the Communities and Native Species Threatened:Low significance/Insignificant
Comments: Primarily an agricultural weed and found on roadsides and waste places (e.g., Radford et al. 1968, Weakley 2002), but may invade native plant communities along disturbance corridors (Kentucky Exotic Pest Plant Council 2001).

Subrank II. Current Distribution and Abundance: High

6. Current Range Size in Nation:High significance
Comments: All states except Alaska, Washington, Oregon, Idaho, Montana, Wyoming, and Colorado (Kartesz 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:High/Moderate significance
Comments: Presumption: assuming some impacts on native biodiversity in most areas given that this species is common and widely planted.

8. Proportion of Nation's Biogeographic Units Invaded:High significance

9. Diversity of Habitats or Ecological Systems Invaded in Nation:High significance

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

10. Current Trend in Total Range within Nation:Medium/Low significance
Comments: Range cannot be expanding in all directions given widespread current range. Presumption that the range is also not decreasing.

11. Proportion of Potential Range Currently Occupied:Low significance/Insignificant
Comments: Temperate areas west of the Cascades might be potential range.

12. Long-distance Dispersal Potential within Nation:High significance
Comments: Very commonly planted as an ornamental; seeds widely available.

13. Local Range Expansion or Change in Abundance:Medium/Low significance
Comments: Presumption that the local range expansion is not likely to double within 10 years, nor is the range likley to be decreasing given increased human-caused disturbance in most areas.

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Low significance
Comments: Primarily an agricultural weed and found on roadsides and waste places (e.g., Radford et al. 1968, Weakley 2002), but may invade native plant communities along disturbance corridors and/or spread from disturbed areas into undisturbed (Kentucky Exotic Pest Plant Council 2001).

15. Similar Habitats Invaded Elsewhere:Medium/Low significance
Comments: Escaped in temperate and tropical habitats around the world (see discussion of distribution in Defelice 2001), so there are possibly a few analogous habitats in the U.S. that have not yet been invaded.

16. Reproductive Characteristics:Moderate significance
Comments: Annual plant with prolific seed production; a single plant can produce 26,000 seeds (Crowley and Buchanan 1982). Seeds of most Ipomoea have a hard seed coat, allowing them to remain viable in the soil for many years (Elmore et al. 1990 as cited in Defelice 2001).

Subrank IV. General Management Difficulty: Medium/Low

17. General Management Difficulty:Medium/Low significance
Comments: Estimate.

18. Minimum Time Commitment:Medium/Low significance
Comments: Estimate.

19. Impacts of Management on Native Species:Medium significance/Insignificant

20. Accessibility of Invaded Areas:High significance
Comments: Very widely planted as an ornamental.
