NatureServe Status

Global Status: G1
Global Status Last Reviewed: 12May2009
Global Status Last Changed: 23May1991
Rounded Global Status: G1 - Critically Imperiled
Reasons: A species with a restricted range and with its habitat declining in quality and extent due to the transition of native vegetation to pine plantation and associated intensive forest management practices. Known only from the Apalachicola River drainage in the southcentral portion of the Florida panhandle. Most occurrences are small and of low quality.
Nation: United States
National Status: N1

U.S. & Canada State/Province Status

NatureServe Global Conservation Status Factors

Range Extent Comments: Florida endemic, Apalachicola Lowlands west of the Apalachicola River; Bay, Calhoun, Franklin, Gulf, Liberty counties, Florida.

Number of Occurrences: 6 - 80
Number of Occurrences Comments: 24 extant occurrences of which 7 have poor viability.

Population Size Comments: Most populations are very small and habitat reduced to a small remnant. Number of individuals in 1988 approximately 2000, but number is probably reduced by shading in pine plantations and by other silvicultural activities. As of 2009, last observed population data for occurrences indicates a total of less than 1500 individuals.

Number of Occurrences with Good Viability/Integrity: Few (4-12)
Viability/Integrity Comments: Only 7 occurrences of A or B quality.

Overall Threat Impact: Very high - high
Overall Threat Impact Comments: Habitat threatened by conversion to pine plantations, intensive management practices, and development. Alterations to hydrology such as draining, ditching, or firebreak construction, as well as mechanical clearing, bedding, and soil disturbance are threats (Chafin 2000).

Short-term Trend: Decline of >30%
Short-term Trend Comments: Habitat rapidly declining, management conditions poor.

Basic Description: A perennial herb, mostly 6-8 cm tall, from a short, stout taproot. Stems are erect. Leaves numerous and crowded toward the base, gradually diminishing in size upward on the stem. Flowering heads are numerous, arranged in spikes. Ray flowers mostly pink to purple; disk flowers yellow Kral, 1983).
Technical Description: "Perennial with a short, basal crown or shortly rhizomatous, often bearing fibrous remnants of old leaf bases about the crown. Stem glabrous to spreading-pubescent, usually solitary, 3-7 dm tall, bearing a terminal spike or raceme of 2 or 3 to about 15 heads. Those leaves closely set at the base of the stem much the largest, stiff, with a linear, long-acute bladed portion 1.5-5 mm broad, only the midvein evident, gradually narrowed below and imperceptibly grading into a subpetiole, mostly 10-15 cm long overall, sometimes sparingly and irregularly ciliate marginally; other leaves much reduced, linear, gradually smaller upwardly. Heads all sessile or on stalks up to about 3 cm long, the uppermost at anthesis first. Involucre turbinate, or turbinate-campanulate, 6-8 mm high, bracts imbricated in several series, erect, subequal or graduated in size, the outer shortest, stiff, subulate, all or all but the innermost shortly spinose at the tip, all green except at their pale bases or the innermost sometimes scarious. Ray flowers 8-15, their ligules 1-1.5 cm long, violet to nearly white; disc corollas yellow. Achene fusiform in outline, about 2 mm long, pubescent" (Godfrey and Wooten, 1981).
Diagnostic Characteristics: Heads spicately or racemosely disposed; involucre turbinate or turbinate-campanulate, 1-1.5 cm broad, its bracts erect (Godfrey and Wooten, 1981).
Duration: PERENNIAL
Palustrine Habitat(s): Bog/fen, HERBACEOUS WETLAND
Terrestrial Habitat(s): Grassland/herbaceous, Savanna, Shrubland/chaparral
Habitat Comments: Grassy openings in shrub-tree bogs, pine savannas, wet prairies, and hillside seepage slopes in mesic pine flatwoods.

Group Name: Flatwoods asters-Eurybia spp.-EOSPECS

Minimum Criteria for an Occurrence: Any naturally occurring population of one or more individuals.
Separation Barriers: Densely planted pine plantations where fire suppression has led to closed canopies, thick shrub layers, and a deep needle duff layer.
Separation Distance for Unsuitable Habitat: 1 km
Separation Distance for Suitable Habitat: 1 km
Alternate Separation Procedure: N/A
Separation Justification: Species in this group are insect pollinated with wind-dispersed seeds; 1 km is sufficient to separate populations.
