Threat ImpactHigh - medium
Range Extent100-250 square km (about 40-100 square miles)
Number of Occurrences21 - 80
Rank Reasons
Endemic to Hells Canyon of the Snake River and its tributaries in western Idaho and adjacent eastern Oregon. Locally common within this narrow range, even dominating the shrub communities on some short stretches of river. Threats include competition from the invasive plant, Himalayan blackberry (Rubus armeniacus). Two sites are extirpated that reduce the range of the species, by 15 river miles (ISSSSP 2010).
Range Extent Comments
Occurs in the Hells Canyon region of the Snake River and its tributaries in western Idaho and adjacent eastern Oregon (ISSSSP 2010). Extirpated sites are excluded from range extent calculations.
Occurrences Comments
Twenty four element occurrences but two of those are extirpated, twelve extant occurrences are in Oregon and nine extant occurrences in Idaho (NatureServe Central Database 2015 and ISSSSP 2010).
Threat Impact Comments
Past disturbances cited include fire, livestock grazing, landslides, powerline installation, road construction, use, erosion and maintenance, and dam construction. Present and future threats include global climate change, noxious weeds, invasive nonnative plants, livestock grazing, noxious weed control, and landslides and possibly fluctuating reservoir levels and flash floods. The greatest threat to the species is the invasive Himalayan blackberry (Rubus armeniacus) (ISSSSP 2010).
Ecology & Habitat

Habitat

At least partially shaded in shrub communities on higher riparian terraces along streams and in shrub-dominated ephemeral stream beds, so water is available in abundance at least seasonally. Also occasionally on lower slopes in mixed shrub communities, but never far from the riparian zone. Soils derived from basalt parent materials (ISSSSP 2010).

Ecology

Observed to be a vigorous root-sprouter after fire (ISSSSP 2010).

Plants commonly associated with Bartonberry are netleaf hackberry (Celtis reticulata), elderberry (Sambucus cerulea), mockorange (Philadelphus lewisii), rocky mountain maple (Acer glabrum), Gooding’s gooseberry (Ribes velutinum var. gooddingii), western white clematis (Clematis ligusticifolia), ninebark (Physocarpus malvaceus), western poison ivy (Toxicodendron), smooth sumac (Rhus glabra), choke cherry (Prunus virginiana), serviceberry (Amelanchier alnifolia), dogwood (Cornus sericea) and bluebunch wheatgrass (Pseudoroegneria spicata) (ISSSSP 2010).
