Teline salsoloides

Teline salsoloides is a critically endangered flowering shrub in the pea family (Fabaceae), part of the broom genus Teline endemic to the Canary Islands. This woody perennial produces small yellow pea-like flowers and slender, often leafless green stems adapted to arid volcanic conditions, an evolutionary strategy that reduces water loss in its harsh island environment. It occupies rocky volcanic slopes and cliff habitats at specific elevations within a highly restricted range, making it vulnerable to any localized disturbance.

The IUCN Red List classifies this species as Critically Endangered, reflecting a severely fragmented population that continues to decline. Its restricted distribution across a small number of sites leaves it exposed to habitat degradation from grazing pressure by feral goats and other introduced herbivores, which strip vegetation from the steep terrain the plant depends upon. Competition from invasive plant species further reduces available habitat, while the small, isolated nature of remaining subpopulations increases susceptibility to stochastic events such as landslides, fires, or prolonged drought common in the Canary Islands' Mediterranean-influenced climate.

Conservation attention has focused on protecting remaining populations within designated natural areas of the islands, where regional environmental authorities monitor plant communities and work to control invasive herbivore access to sensitive slopes. Seed banking and ex situ propagation efforts for Canarian endemic flora, coordinated through island botanical institutions, offer a measure of insurance against further wild population loss. Encouragingly, growing recognition of the Canary Islands' exceptional endemic plant diversity has strengthened local conservation policy and increased funding for habitat restoration projects targeting rare shrubs like this one.

Continued monitoring of population trends, combined with targeted invasive species control, represents the clearest path toward stabilizing this species before its narrow range and declining numbers push it closer to extinction in the wild.

This endemic legume inhabits coastal scrublands and rocky slopes in the Canary Islands, typically growing in arid, well-drained soils at low to moderate elevations. It thrives in the specialized xerophytic vegetation communities characteristic of the Canarian coastal zone.
