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/Insignificant
Rounded I-Rank: Unknown
I-Rank Reasons Summary: Widely characterized as being locally common but not particularly invasive.
Subrank I - Ecological Impact: Medium/Insignificant
Subrank II - Current Distribution/Abundance: Medium
Subrank III - Trend in Distribution/Abundance: Medium/Insignificant
Subrank IV - Management Difficulty: Medium/Insignificant
I-Rank Review Date: 23Mar2004
Evaluator: Fellows, M.
Native anywhere in the U.S?
Native Range: Middle East north to China, the Caucasus and south to India, Central Europe and northern Africa (GRIN 2001).

Screening Questions

S-1. Established outside cultivation as a non-native? YES
Comments: (Kartesz 1999).

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Waysides and cultivated ground (Strausbaugh 1978).

Subrank I - Ecological Impact: Medium/Insignificant

1. Impact on Ecosystem Processes and System-wide Parameters:Low significance
Comments: Can concentrate high levels of nitrates in leaves when growing on high nitrogen soils (MPL, Undated).

2. Impact on Ecological Community Structure:Unknown

3. Impact on Ecological Community Composition:Unknown

4. Impact on Individual Native Plant or Animal Species:Unknown

5. Conservation Significance of the Communities and Native Species Threatened:Low significance/Insignificant
Comments: Waysides and cultivated ground (Strausbaugh 1978). Fields, gardens and disturbed areas (MPL, Undated).

Subrank II. Current Distribution and Abundance: Medium

6. Current Range Size in Nation:High significance
Comments: (Kartesz 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Low significance/Insignificant
Comments: Considered wide spread, but not harmful in the eastern US (USFS-ER 2004).

8. Proportion of Nation's Biogeographic Units Invaded:High significance
Comments: >50 ecoregions, inferred from Kartesz (1999) and TNC (2001).

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Low significance
Comments: Waysides and cultivated ground (Strausbaugh 1978).

10. Current Trend in Total Range within Nation:Medium/Low significance
Comments: Inferred from current distribution (Kartesz 1999).

11. Proportion of Potential Range Currently Occupied:Low significance/Insignificant
Comments: Inferred from current distribution (Kartesz 1999).

12. Long-distance Dispersal Potential within Nation:High/Moderate significance
Comments: Endozoochory and water (USACE 1998).

13. Local Range Expansion or Change in Abundance:Unknown

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Low significance/Insignificant
Comments: Waysides and cultivated ground (Strausbaugh 1978). Fields, gardens and disturbed areas (MPL, Undated).

15. Similar Habitats Invaded Elsewhere:High/Low significance
Comments: Canada (Kartesz 1999) and Panama (NatureServe, unpubl. data).

16. Reproductive Characteristics:Insignificant
Comments: Reproduces by seed, does not root at nodes. Most mallows have a seed bank, and some can be very long-lived (Michael et al. 2003).

Subrank IV. General Management Difficulty: Medium/Insignificant

17. General Management Difficulty:Low significance
Comments: Increasing turf grass density may decrease ability of Malva neglecta to compete (Sedbrook 2004). Pre-emergent herbicides, as post-emergent herbicides are not very effective (Sedbrook 2004). Hoe or pull out young plants (Sedbrook 2004).

18. Minimum Time Commitment:High/Low significance
Comments: Most mallows have a seed bank, and some can be very long-lived (Michael et al. 2003).

19. Impacts of Management on Native Species:Low significance/Insignificant
Comments: Malva neglecta is a primarily a weed of lawns and cultivated gardens (Strausbaugh 1978).

20. Accessibility of Invaded Areas:Low significance
Comments: Is most commonly found in lawns; may be sold/used in butterfly gardens.
