NatureServe Status

Global Status: G2
Global Status Last Reviewed: 24May2006
Global Status Last Changed: 05Dec1988
Rounded Global Status: G2 - Imperiled
Reasons: The species' geographic range is limited to high elevations in the Mosquito Range and the Hoosier Ridge area of the Colorado Rocky Mountains. There are nine document occurrences, four with good or excellent viability. Motorized recreation is rapidly increasing in areas where this species grows. Mining claims exist throughout the range of Ipomopsis globularis and, although most are not currently active, they represent a potential threat to the species.
Nation: United States
National Status: N2

U.S. & Canada State/Province Status

NatureServe Global Conservation Status Factors

Range Extent Comments: Endemic to the Mosquito Range in central Colorado; known from Lake, Park, and Summit counties. Estimated range is 284 square kilometers (110 square miles), calculated in 2008 by the Colorado Natural Heritage Program in GIS by drawing a minimum convex polygon around the known occurrences.

Area of Occupancy: 6-25 4-km2 grid cells
Area of Occupancy Comments: The total occupied habitat is about 3,100 acres. Occurrences without specific information on occupied habitat were considered to occupy 0.5 acre. Spackman Panjabi and Anderson (2005) conclude that the known occupied habitat of Ipomopsis globularis is less than 4,000 acres.

Number of Occurrences: 6 - 20
Number of Occurrences Comments: There are 9 principal occurrences documented in the Colorado Natural Heritage Program database. 5 of the 9 occurrences have not been observed in over 20 years. The USFS Conservation Assessment also documents 9 occurrences (Spackman Panjabi and Anderson 2005).

Population Size Comments: Total estimated sum of individuals from 5 of the 9 occurrences is 2,160. The remaining occurrences do not report the number of individuals. Spackman Panjabi and Anderson (2005) estimate that the population is about 6,000 to 11,000 individuals.

Number of Occurrences with Good Viability/Integrity: Few (4-12)
Viability/Integrity Comments: There are 4 occurrences with an A or B rank.

Overall Threat Impact: High
Overall Threat Impact Comments: The primary threat at this time is considered to be motorized recreation (Rondeau et al. 2011). Other potential threats are from mining, exotic species invasion, effects of small population size, collection for horticultural trade, non-motorized recreation, global climate change, and pollution. Motorized recreation is rapidly increasing in areas where this species grows, and it is extremely difficult to enforce regulations or to close access to protect populations. The entire global range of I. globularis is vulnerable to mining development; however, the scale and time frame within which mining activity might occur is unknown. Historic mining is widely evident in this species' habitat. Land ownership patterns are extremely complex within the range of I. globularis and even within individual occurrences. Despite its narrow range, this species is found on lands administered by three ranger districts on two national forests (South Park and Leadville of the Pike-San Isabel, and Dillon of the Arapaho as administered by the White River), and hundreds if not thousands of private landowners. These complex land ownership patterns make conservation efforts difficult. (Spackman Panjabi and Anderson 2005).

From Steve Olson (USFS Pike San Isabel) 2012: Threats to Ipomopsis globularis may include unregulated recreation (motorized and non-motorized), collecting (for rock-gardens), mining, non-native invasive species, pollution, and climate change (NatureServe 2012, Panjabi and Anderson 2005). All or part of one large population is protected by the Hoosier Ridge Research Natural Area. This species appears to be somewhat tolerant of disturbance.

Short-term Trend: Unknown
Short-term Trend Comments: There are no quantitative data available to infer the population trend of Ipomopsis globularis (Spackman Panjabi and Anderson 2005). Loss of habitat and anthropogenic disturbance of habitat has probably caused a downward trend since the area was settled approximately 140 years ago (Spackman Panjabi and Anderson 2005).

Long-term Trend: Unknown
Long-term Trend Comments: Unknown.

Ecology & Life History
Help
Basic Description: A perennial herb, 1.5 dm tall, with a strong, sweet fragrance. Produces white or pale purple flowers in a globe-like cluster surrounded by long, wooly hairs. Blooms July-early August.
General Description: Ipomopsis globularis is a perennial herb growing 10 to 15 cm (4 to 6 inches) tall. Leaves are pinnately lobed, and the lobes are narrowly linear. The larger leaves are basal, but there are a few smaller leaves on the stems. Stems are densely woolly. Flowers are in terminal, ball-like, wooly clusters. Flowers are pale purple and have a strong fragrance (Spackman et al. 1997, FNA 1993+).
Reproduction Comments: The species may be self-incompatible, requiring cross-fertilization (Panjabi and Anderson 2005). Numbers in populations that have been revisited appear to vary with the local weather conditions. Seeds are likely to be dispersed by wind and water (Panjabi and Anderson 2005).
Terrestrial Habitat(s): Alpine
Habitat Comments: Ipomopsis globularis is found on alpine ridges with gravelly, calcareous soil. Habitats are described as meadows, talus, and scree slopes, often with 50 percent bare soil. Plants have been seen on abandoned mine spoils. Sites are underlain by Leadville limestone and Manitou limestone formations (Panjabi and Anderson 2005). Populations occur on all aspects and flat to very steep slopes. Frequently associated species of Ipomopsis globularis include Geum rossii, Artemisia scopulorum, Bistorta bistortoides, Campanula uniflora, Castilleja occidentalis, Deschampsia cespitosa, Elymus trachycaulus, Lloydia serotina, Oxytropis splendens, Pedicularis scopulorum, Polemonium viscosum, and Silene acaulis (Panjabi and Anderson 2005).
