Rank Reasons
Delphinium novomexicanum is endemic to 2 mountain ranges in south central New Mexico. Although perceived by local botanists as locally common, there are few documented EOs and little information on its distribution or abundance.
Range Extent Comments
Delphinium novomexicanum is an endemic species to the Sacramento and White mountains in Lincoln and Otero Counties, New Mexico.
Occurrences Comments
Delphinium novomexicanum has been described as fairly common within its range, but it has been collected very infrequently and there are few documented EOs. Twenty-two EOs, but four are historic (NatureServe Central Database 2015).
Threat Impact Comments
Any land use practice that results in drying riparian zones and wet meadows are likely to pose a threat to this species. Potential man-made threats include activities associated with livestock grazing, logging, and diverting water resources for control of forest fire and other uses. It is unknown whether livestock use this species of Delphinium. Some Delphiniums are poisonous to cattle, so the genus as a whole is sometimes targeted for poisonous weed control by the ranching industry (Robert Sivinski, personal communication). The importance of fire in the life-history of this species is unknown. It is possible that either restricting forest fire or allowing unchecked wildfire may pose a threat. Invasive weeds may also be a threat especially considering the preferred habitat.
Ecology & Habitat

Habitat
