(Jessica's aster) grows in the Palouse grasslands
and prairie/forest transition zones of southeastern Washington.
Loss of habitat to agriculture may have contributed to the
decline of this State endangered species. It's also possible
that its pollinators have been affected by pesticide use.
sedge) is found in wet meadows, marshes and lakeshores.
Changing water regimes (human activity altering wetland
landscapes) and competition from an invasive species, reed
canarygrass (Phalaris arundinacea), challenge this
sedge's survival. Shoreline development and logging may
also contribute to its decline.
helleborine) grows in many parts of the state,
especially along the Columbia River. It has been upgraded
to Washington's Watch List. But changes in hydrologic regime,
grazing, road construction, deforestation and development,
and possibly the use of herbicides in lakes and waterways
all threaten this orchid.
is known to grow in one small area in Chelan County. It's
adapted to harsh habitats cliffs and rocky outcrops.
Still, rock climbing, road maintenance and herbicide applications
may affect its survival.
is endangered in the State of Washington because it has
been found in just one prairie. The encroachment of conifers
and non-native shrubs due to fire suppression is a concern.
ssp. viscidum (woodsage),
on Washington's Watch List,
can deal with seasonal fluctuations between spring inundation
and late summer dryness. But even though rhizomes may help
it tolerate some grazing, heavy grazing is too much for
it. Other threats are ORVs and recreational trampling, competition
with non-natives, changes in hydrologic regime and possibly
to Washington's rare plants
