Stephanomeria runcinata is a species of flowering plant in the family Asteraceae known by the common name desert wirelettuce. [1]
It was evaluated by NatureServe as globally secure (G5) in 1988. At the state/provincial level they evaluated populations in Alberta, Saskatchewan, and Wyoming as "vulnerable" S3, with Montana, Quebec, and Wyoming as "apparently secure" S4. They evaluate populations in Labrador, Nunavut, and Manitoba as "vulnerable" S3, and the Yukon, Alaska, and Saskatchewan as "imperiled" S2. The only area they assessed the populations as "critically imperiled" S1 at that time was Newfoundland. They have not yet evaluated the rest of the natural range of the species. [1]
The NatureServe conservation status system, maintained and presented by NatureServe in cooperation with the Natural Heritage Network, was developed in the United States in the 1980s by The Nature Conservancy (TNC) as a means for ranking or categorizing the relative imperilment of species of plants, animals, or other organisms, as well as natural ecological communities, on the global, national or subnational levels. These designations are also referred to as NatureServe ranks, NatureServe statuses, or Natural Heritage ranks. While the Nature Conservancy is no longer substantially involved in the maintenance of these ranks, the name TNC ranks is still sometimes encountered for them.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
SRANK or Subnational Rank seeks to ascertain the rarity of species within subnational boundaries.
Stephanomeria is a genus of North American plants also known as wirelettuce, belonging to the tribe Cichorieae within the family Asteraceae.
Aster alpinus, the alpine aster or blue alpine daisy, is a species of flowering plant in the family Asteraceae, native to the mountains of Europe, with a subspecies native to Canada and the United States. This herbaceous perennial has purple, pink, or blue flowers in summer.
Packera glabella is one of several plants with the common name butterweed, this one has also been called cressleaf groundsel and yellowtop. It is native to central and southeastern North America but spreads so aggressively, overtaking other native plants, that it is considered invasive. Further, when eaten, it is toxic to humans and highly toxic to horses & cattle. Authorities recommend eradicating it, conventionally with 2,4-D.

Other common names include common fleabane, daisy fleabane, frost-root, marsh fleabane, poor robin's plantain, skervish, and, in the British Isles, robin's-plantain, but all of these names are shared with other species of fleabanes (Erigeron). It is native to North America and has been introduced to Eurasia.

It is a somewhat fleshy annual herb producing a branching, slender stem that has a mealy whitish texture when young and turns dull to bright red with age, losing its grainy coat. It grows up to 14 to 20 centimeters tall. The thick oblong leaves are up to a centimeter long. Clusters of 1 to 3 minute flowers appear in the leaf axils, each flower made up of 3 tiny sepals.
Symphyotrichum oblongifolium, commonly known as aromatic aster or oblong-leaved aster, is a species of flowering plant in the family Asteraceae and is native to parts of the eastern and central United States. It is an uncommon herbaceous perennial that reaches heights of 10–80 centimeters and blooms August–November with many flower heads in various shades of purple.
Stephanomeria exigua, the small wirelettuce, is a perennial or biennial plant native to the western United States. It is thought to be the parent species of Stephanomeria malheurensis, an endangered plant species found only in southern Oregon. It generally blooms from mid-spring to late summer and produces small, light pink or light purple blooms.
Castilleja septentrionalis is a species of Indian paintbrush known by several common names, including northern paintbrush, sulfur paintbrush, and pale painted cup. There is taxonomic disagreement as to if it is one species widely distributed in mountain and alpine environments of North America or if there is a second species, Castilleja sulphurea, in the Rocky Mountains.
