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: Range is limited to frost-free regions of the U.S. where it invades rare and vulnerable habitats.
Subrank I - Ecological Impact: Medium/Low
Subrank II - Current Distribution/Abundance: Low
Subrank III - Trend in Distribution/Abundance: Medium/Low
Subrank IV - Management Difficulty: Medium/Insignificant
I-Rank Review Date: 20Feb2004
Evaluator: Fellows, M.
Native anywhere in the U.S?
Native Range: Tropical Asia, northern Australia (Langeland and Craddock Burks 1998); maybe Tropical Africa as well (hort.purdue)

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: (Langeland and Craddock Burks 1998)

Subrank I - Ecological Impact: Medium/Low

1. Impact on Ecosystem Processes and System-wide Parameters:Medium/Low significance
Comments: largely inferred from effects in native range: known to fix nitrogen (Langeland and Craddock Burks 1998); at rate of 8.60 (+/- 3.5) moles N2/gram/hour - which is 1/3 of Acacia pennatula (Purdue 2004, New Crops); in its native range (Australia) the community of grasses beneath the tree vs. the grass community a few meters away was different - this effect is thought to be a result of improved soil moisture (which is linked to higher mineralization of organic matter) under the shade of a tree in an arid environment (Lowry et al. 1998)

2. Impact on Ecological Community Structure:Medium/Low significance
Comments: can form dense stands (Weber 2003); inferred - presence in pine rockland/grassland/coastal strand communities increases number of layers

3. Impact on Ecological Community Composition:Low significance
Comments: can shade out native species (Weber 2003); out competes native species (DERM 2003)

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

5. Conservation Significance of the Communities and Native Species Threatened:Moderate significance
Comments: threatens pine rockland communities (Langeland and Craddock Burks 1998; DERM 2003)

Subrank II. Current Distribution and Abundance: Low

6. Current Range Size in Nation:Low significance/Insignificant
Comments: HI, TX, FL and maybe CA (Kartesz 1999); no CA distribution reported in Jepson Manual Online (Baldwin et al. 2004)

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Moderate significance
Comments: firmly entrenched in south Florida (DERM 2003); no mention in either TX or HI

8. Proportion of Nation's Biogeographic Units Invaded:Low significance
Comments: at most 9 TNC Ecoregions - inferred from Kartesz (1999) and TNC (2001); (Wunderlin and Hansen 2004)

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Moderate significance
Comments: tropical hammocks, pine rocklands, disturbed areas, rockland hammocks, coastal hammocks (Langeland and Craddock Burks 1998); broad range of habitats: pine rockland, hardwood forest, coastal strand, scrubby flatwoods, mangrove-buttonwood forests (DERM 2003)

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

10. Current Trend in Total Range within Nation:Medium/Low significance
Comments: by 1933 noted as invading tropical hammocks in Florida Keys, by 1990 known as 'common' throughout Keys, Central and South Florida, will not tolerate freezing (Langeland and Craddock Burks 1998); seedlings will not tolerate frost (Lowry et al. 1998)

11. Proportion of Potential Range Currently Occupied:Low significance
Comments: in most of potential range in Florida (Wunderlin and Hansen 2004); limited to frost-free zones (Langeland and Craddock Burks 1998; Lowry et al. 1998)

12. Long-distance Dispersal Potential within Nation:Moderate significance
Comments: ornamental (but no longer for sale in S. Florida (FLEPPC 2003), crows and squirrels in India (Langeland and Craddock Burks 1998); wind carries intact pods for 100's of meters (Lowry et al. 1998)

13. Local Range Expansion or Change in Abundance:Unknown

14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:High significance
Comments: establishes in intact pine rocklands, coastal strand and tropical hammocks (DERM 2003)

15. Similar Habitats Invaded Elsewhere:Low significance
Comments: elsewhere in Caribbean, Central and South America, including moist and dry hillsides in Puerto Rico (Langeland and Craddock Burks 1998; Weber 2003); southern Africa (Weber 2003); native to the rainforest-eucalypt woodland ecotone and semi-deciduous mesophyll vine-forest in Australia (Lowry et al. 1998)

16. Reproductive Characteristics:Medium/Low significance
Comments: fast growing from seed (Langeland and Craddock Burks 1998); produces massive quantities of seed (Langeland and Craddock Burks 1998); large amounts of seed (Weber 2003); suckers from roots (Weber 2003; DERM 2003)

Subrank IV. General Management Difficulty: Medium/Insignificant

17. General Management Difficulty:Medium/Low significance
Comments: hand pull seedlings; dig out saplings; hack and squirt adults (Weber 2003)

18. Minimum Time Commitment:Unknown

19. Impacts of Management on Native Species:Low significance
Comments: inferred from best management practices

20. Accessibility of Invaded Areas:Unknown
