General Information

DeBeque phacelia is a low-growing, herbaceous, spring annual plant with a tap root. The stems are typically 0.8 to 3 in (2 to 8 cm) long, often branched at the base and mostly lying flat on the ground as a low rosette. Stems are often deep red and more or less hairy with straight and stiff hairs. Leaves are similarly hairy, reddish at maturity, 0.2 to 0.6 in (5 to 15 mm) long, egg-shaped or almost rectangular with rounded corners, with bases abruptly tapering to a wedge-shaped point. Leaf margins are smooth or toothed. The tube-shaped flowers are yellowish white, on short stems; the 5 petals are 0.16 to 0.19 in (4-5 mm) long; the stamens do not protrude beyond the petals. The elongated egg-shaped seeds are 0.6 to 0.8 in (1.5 to 2 mm) long with 6 to 12 crosswise corrugations, and are blackish brown and somewhat iridescent. DeBeque phacelia is subject to human-caused modifications from natural gas exploration and production with associated expansion of pipelines, roads, and utilities; development within the Westwide Energy Corridor; increased access to the habitat by off highway vehicles; soil and seed disturbance by livestock and other disturbances; and the inadequacy of existing regulatory mechanisms.

Habitat Requirements

DeBeque phacelia is restricted to exposures of chocolate to purplish brown and dark charcoal gray alkaline clay soils derived from the Atwell Gulch and Shire members of the Wasatch Formation. These expansive clay soils are found on moderately steep slopes, benches, and ridge tops adjacent to valley floors of the southern Piceance Basin in Mesa and Garfield Counties, Colorado. On these slopes and soils, DeBeque phacelia usually grows only on one unique small spot of ground that shows a slightly different texture, color, and crack pattern than the similar surrounding soils. We do not have a precise scientific description of the soil features required to support this species. The natural shrink-swell cracking process creates the conditions needed for the plants and seed bank to thrive.

Movement / Home Range

DeBeque phacelia is a rare annual plant endemic to clay soils derived from the Atwell Gulch and Shire members of the Wasatch Formation in Mesa and Garfield Counties, Colorado. A general range encompassing outlying occurrences of DeBeque phacelia includes about 82,231 ac (34,896 ha). The growing town of DeBeque and about 10 mi (16.4 km) of Interstate 70 and the Colorado River bisect the speciesí range.

Reproductive Strategy

DeBeque phacelia plants flower between late April and late June and set seed from mid-May through late June. Individuals finish their life cycle by late June to early July, after which time they dry up and disintegrate or blow away, leaving no indication that the plants were present . The species grows in a habitat with wide temperature fluctuations, long drought periods, and erosive saline soils. Upon drying, cracks form in the shrink-swell clay soils. Seeds plant themselves by falling into the cracks that close when wetted, thus covering the seeds.

Other

DeBeque phacelia seeds can remain dormant for 5 years (and probably longer) until the combination and timing of temperature and precipitation are optimal for germination.
