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: High/Low
Rounded I-Rank: Unknown
I-Rank Reasons Summary: Atriplex rosea is established as a weed in alkaline soil in the western U.S. and occasionally found in waste places in the northeastern U.S. It has become abundant in alkaline valleys and plains in the western U.S. where it sometimes forms pure stands in those habitats. It is listed as an invasive plant in Wyoming and considered invasive at Whiskeytown National Recreation Area in northern California. It occurs in native species habitats such as a desiccated montane lake-bed in California, springs associated with a greasewood/saltgrass plant community in Washington State, in a small disturbed wetland in Walla Walla, Washington, and in riparian habitats in Utah but little other information is available. Atriplex rosea is widely branched, allowing it to become a tumbleweed which can spread seed over large areas. More current information on this species is needed, especially on ecological impacts, trends in distribution and abundance, and management difficulty.
Subrank I - Ecological Impact: Medium/Low
Subrank II - Current Distribution/Abundance: High/Medium
Subrank III - Trend in Distribution/Abundance: High/Low
Subrank IV - Management Difficulty: Unknown

S-2. Present in conservation areas or other native species habitat? Yes
Comments: Occurs in a desiccated montane lake-bed in the San Bernardino Mountains of California (Ferren et al. 1996). Occurs at a springs associated with a greasewood/saltgrass plant community in the Columbia Basin of Washington State (Sackschewsky and Downs 2001). Occurs in a small disturbed wetland in Walla Walla, Washington (Meridian Environmental 2001). In Utah, it is a widely established weedy species of disturbed sites, often in riparian habitats or in barnyards or animal bedgrounds (Welsh et al. 1993).

Subrank I - Ecological Impact: Medium/Low

1. Impact on Ecosystem Processes and System-wide Parameters:Medium significance/Insignificant
Comments: No mention of changes in abiotic ecosystem processes or system-wide parameters found in the literature; assumption is that any alterations are not major/irreversible.

2. Impact on Ecological Community Structure:High/Moderate significance
Comments: It has become abundant in alkaline valleys and plains in the western U.S. where it sometimes forms pure stands in those habitats (Hall and Clements 1923 in Cavers 1995).

3. Impact on Ecological Community Composition:High/Moderate significance
Comments: It has become abundant in alkaline valleys and plains in the western U.S. where it sometimes forms pure stands in those habitats (Hall and Clements 1923 in Cavers 1995). Listed as an invasive plant in Wyoming (Hartman and Nelson 2000). Considered invasive at Whiskeytown National Recreation Area in northern California (NPS 2003). It is not on the list of Harmful Non-Indigenous Species in the United States (U.S. Congress 1993).

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

5. Conservation Significance of the Communities and Native Species Threatened:Low significance
Comments: Established as a weed in alkaline soil in the western U.S. and occasionally found in waste places in the northeastern U.S. (Gleason and Cronquist 1991). Apparently, it usually occurs in disturbed habitats but it may sometimes occur in significant habitats. Occurs in a desiccated montane lake-bed in the San Bernardino Mountains of California (Ferren et al. 1996). Occurs at a springs associated with a greasewood/saltgrass plant community in the Columbia Basin of Washington State (Sackschewsky and Downs 2001). Occurs in a small disturbed wetland in Walla Walla, Washington (Meridian Environmental 2001). In Utah, it is a widely established weedy species of disturbed sites, often in riparian habitats or in barnyards or animal bedgrounds (Welsh et al. 1993).

Subrank II. Current Distribution and Abundance: High/Medium

6. Current Range Size in Nation:High significance
Comments: Widespread in the western United States and also scattered in many eastern states (Kartesz 1999).

7. Proportion of Current Range Where the Species is Negatively Impacting Biodiversity:Medium significance/Insignificant
Comments: Apparently currently having negative impacts in a relatively small percentage of its range. Listed as an invasive plant in Wyoming (Hartman and Nelson 2000). Considered invasive at Whiskeytown National Recreation Area in northern California (NPS 2003). It is not on the list of Harmful Non-Indigenous Species in the United States (U.S. Congress 1993). The following information is from 1923. It has become abundant in alkaline valleys and plains in the western U.S. where it sometimes forms pure stands in those habitats (Hall and Clements 1923 in Cavers 1995).

8. Proportion of Nation's Biogeographic Units Invaded:High significance
Comments: Present in all states west of the Mississippi except Oklahoma and also in a number of eastern states, therefore in most ecoregions (Kartesz 1999; TNC 2001).

9. Diversity of Habitats or Ecological Systems Invaded in Nation:Moderate significance
Comments: Occurs in a desiccated montane lake-bed in the San Bernardino Mountains of California (Ferren et al. 1996). Occurs at a springs associated with a greasewood/saltgrass plant community in the Columbia Basin of Washington State (Sackschewsky and Downs 2001). Occurs in a small disturbed wetland in Walla Walla, Washington (Meridian Environmental 2001). In Utah, it occurs in riparian habitats (Welsh et al. 1993).

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

10. Current Trend in Total Range within Nation:High/Low significance
Comments: It is found in disturbed areas. In California, it is common and occurs in open disturbed places and fields (Baldwin et al. 2004). Found in waste places in the northeastern U.S. (Gleason and Cronquist 1991). Disturbed areas are not declining, therefore it is presumed to be not declining.

11. Proportion of Potential Range Currently Occupied:Low significance
Comments: Roughly 70%, inferred from Kartesz (1999) and TNC (2001). Widespread, but could potentially spread further within the region based on Kartesz (1999) and USDA 1990).

12. Long-distance Dispersal Potential within Nation:High/Moderate significance
Comments: In the American mid-west this species has spread rapidly as a tumbleweed and is especially common along roadsides and fencerows (Hall and Clements 1923 in Cavers 1995). Atriplex rosea is widely branched, allowing it to become a tumbleweed which can spread seed over large areas (Cavers 1995).

13. Local Range Expansion or Change in Abundance:High/Low significance
Comments: It is found in disturbed areas. In California, it is common and occurs in open disturbed places and fields (Baldwin et al. 2004). Found in waste places in the northeastern U.S. (Gleason and Cronquist 1991). Disturbed areas are not declining, therefore it is presumed to be not declining.


14. Inherent Ability to Invade Conservation Areas and Other Native Species Habitats:Low significance
Comments: Apparently present in few native species habitats in the U.S. In the Czech Republic (where it is also non-native), it has been present since before 1500, and is considered to be stable or decreasing in population and is restricted to human-made habitats (Pysek et al. 2002).

15. Similar Habitats Invaded Elsewhere:Moderate significance
Comments: It has invaded saltpans in New Zealand (Tussock Grasslands MIS Development Team 2001). Apparently, it has not yet invaded saltpans in the U.S. In Canada, it occurs on disturbed praire and sandy blowouts (Cavers 1995). It may not have invaded these habitats in the U.S. yet.

16. Reproductive Characteristics:Low significance
Comments: Atriplex rosea is an annual and is primarily wind pollinated (Cavers 1995). Atriplex rosea is widely branched, allowing it to become a tumbleweed which can spread seed over large areas (Cavers 1995). Atriplex patula, a related species, was found to produce between 100 and 6000 seeds per plant (Hanf 1973 in Cavers 1995).

Subrank IV. General Management Difficulty: Unknown

17. General Management Difficulty:High/Low significance
Comments: At Whiskeytown National Recreation Area, Atriplex rosea is considered invasive and subject to eradication (NPS 2003). Apparently, management is necessary and it persists without repeated reintroduction.

18. Minimum Time Commitment:Low significance/Insignificant
Comments: It is an annual (Cavers 1995), so presume control does not require more than 5 years.

19. Impacts of Management on Native Species:Unknown

20. Accessibility of Invaded Areas:Medium significance/Insignificant
Comments: At Whiskeytown National Recreation Area, Atriplex rosea is considered invasive and subject to eradication (NPS 2003) so presume accessibility problems not severe.
