Threats to the plant include changes in the local hydrology, because the plant relies on a certain level of moisture in its microhabitat.

Current threats include changes in local hydrology and the invasion of noxious weeds, such as Lepidium latifolium.

During development, the local hydrology is altered, eliminating natural springs and causing polluting runoff.

Within the park the species may be affected by changes in the local hydrology and the fire regime and the invasion of non-native plants.

Other threats include agricultural activity and changes in the local hydrology.

Threats to the species include loss of habitat to residential development, changes in the local hydrology, logging, and grazing.

Habitat can also be degraded when the local hydrology is altered, making the land too dry or permanently wet.

The function of the ridging and ditching differed according to local hydrology.

These threats include urban development, trash dumping and pollution, vehicles, fire, grazing, and alterations in the local hydrology.

However, habitat degradation does occur via alteration of the local hydrology and the process of succession.
