Ute Ladies' Tresses Orchid
Spiranthes diluvialis
Ute ladies' tresses orchid (Spiranthes diluvialis) prefers wet riparian areas that are fairly open. It does not thrive in close proximity to shrubs and trees. They are one of the first species to colonize streamside habitats such as sandy bars or cobbly edges of streams. Aggressive exotic species such as purple loosestrife and reed canary grass can force Ute ladies tresses out of certain areas. Recent invasions of weedy species are one of the largest threats to this plant.
Loss of habitat through agriculture and development is another major threat to the sustainability of this species. Ute ladies tresses rely on streamside habitats that are periodically grazed. As waterways are more controlled through diversions and dams, this plants' habitat is increasingly restricted. Seasonal grazing can be compatible with this species, but year-round grazing can have a detrimental effect on the plant.
In addition, this plant has a low reproductive rate and is dependent on pollinators for reproduction. The loss of pollinators significantly reduced the reproductive potential of this species.
