The Pyramid Lake Paiute Tribe has been committed to protecting riparian ecosystems, agricultural lands, rangelands, and wetlands to benefit spawning fish, aquatic life and wildlife. Cultural Resources also are a priority for protection. Abundant species of willows, tule, and native plants are harvested by tribal members throughout the riparian lands, as well as, chokecherry and elderberries in canyons with perennial streams and springs.  Because of high infestation of noxious weeds within the riparian zone, much effort has been placed in eradicating and reducing weeds in these areas.​

There is a significant infestation of invasive weed species including saltcedar (tamarix SPP.), tall whitetop (lepidium draba), and Russian olive (elaeagnus angustifolia) in areas on the reservation and it is quickly displacing native cottonwoods, willows, and other riparian vegetation along the lower Truckee River. Invasive species threatens the abusdance of native species due to uncontrollable population’s growth. Some noxious weed species such as cheatgrass burn easily and increase the risk of wildfires. Environmental impacts from invasive species infestations include increased erosion into waterways and loss of native habitats, Invasive plants populations along the waterways grown and spread their seed. Seeds can easily be carried down waterbodies or by wind to infest other locations which in turn increases costs associated with prevention (economicimpacts from prevetion, crop loss, etc.), reduces biodiversity, and displaces native species.

The Tribe conducts active measures for specific invasive species reduction and implements riparian enhancements in areas located along the lower Truckee River within the Reservation. The task objectives include:

  • Reduction and/or removal of saltcedar, tall whitetop, Russian Olive, and cheatgrass riparian

  • Public outreach activities to inform the public of any environmentally sensitive impacts.

Early Detection Early Response

With the varied sizes of infestations of noxious weeds, the Weed Crew, Environmental Specialists and Technicians are constantly on the lookout for new establishments of weeds that can be managed expeditiously. Weed crews are often dispatched to the field to obtain waypoints or use GPS units to find specific locations of new establishments and can transfer placement to maps.

The Tribe has developed a responsive relationship with federal, state, and local resources to assist with weed management activities within the reservation and is affiliated with the Lower Truckee River Cooperative Weed Management Area (LTRCWMA) within the counties of Washoe, Storey and Lyon Counties.
