CTUIR Native Plant Nursery Operational Support X

The CTUIR Tribal Native Plant Nursery exists primarily to provide materials for restoration projects conducted by the Fisheries and Wildlife Habitat programs of the tribes and their county, state and federal conservation partners in the region. Plant materials produced at the Nursery are planted along numerous tributaries of the Lower Snake River and the Mid-Columbia River. These plants provide shade and bank stabilization; practices that benefit threatened summer steelhead, threatened bull trout, and threatened and reintroduced Chinook and Coho salmon. Nursery employees collect seed and cuttings near each project site to produce plants that are adapted to the unique soil and climate conditions of each site. Collection procedures and cultural practices are followed to maintain genetic diversity and to produce plants that are capable of surviving the austere conditions of this region. Services include site assessment and treatment prescription development, seed and cutting collection and propagation and maintenance of specified native plant species. Locally sourced materials assure higher planting success and prevent unintended introduction of non-adapted genetic materials to the watersheds. Native riparian plants provide shade, structure and a substrate for macro invertebrates that feed native fish stocks.



Worksite #1 Proposed Work.

PCSRF funds help support nursery operations, including the following tasks:



Develop planting plan with Habitat project managers, conservation partner project leaders, and contractors for restoration project.



Collect seed and/or cuttings from proposed site and prepare for propagation.



Sow appropriately to produce plants that are suitable for project site and meet target dates for out-planting.



Maintain plants in a manner that encourages robust root growth and adequate shoot growth.



Monitor for diseases and pests, changing practices as needed to produce healthy plants.



Harden plants with changes to fertilizer and irrigation protocols to encourage dormancy.



If needed, overwinter in protected space, transplant to desired container, then manage growth until the next planting season.



Communicate with habitat managers regarding success of particular species and container types, making necessary adjustments to future planting plans.

Plant materials produced at the Nursery benefit Threatened summer steelhead, Threatened bull trout, and Threatened and reintroduced Chinook and Coho salmon by assuring the availability of healthy and vigorous locally sourced native plant materials for use in habitat restoration projects by tribal entities (CTUIR, Nez Perce, Yakama and Burns Paiute) and conservation partners (USFS, USFWS, OR Dept of Parks and Recreation, ODFW, ODOT, County Soil and Water Conservation Districts and City Parks), enrollees in DOI projects such as the Sage Grouse Initiative, EQUIP, CURB and CREP. Also, various non-profit organizations such as the National Wild Turkey Federation, Blue Mountain Land Trust, Walla Walla Basin Watershed Council, Umatilla Basin Watershed Council and North Fork John Day Watershed Council.



Plants grown at the Tribal Native Plant Nursery (TNPN) are from seed collected by the nursery at the project sites or at nearby locations with similar abiotic and plant community characteristics. While it is more expensive to gather seed and raise plants with this degree of fidelity to local genetics, the prices at TNPN are generally comparable to other nurseries who do not apply such standards in seed selection.

Although we do not have the metrics to evaluate success rates of TNPN plants compared to plants from other nurseries, the value of growing plants from locally adapted seed has been demonstrated in multiple common garden studies. It is not surprising that planting success and long range outcomes are superior when the genetics have been challenged with conditions specific to this area. Locally sourced materials not only assure long term resilience, they also prevent unintended introduction of non-adapted genetic materials to the watersheds.



Native riparian plants provide shade, structure and a substrate for macroinvertebrates that feed native fish stocks. Native plant products support CTUIR’s “River Vision” which identifies a healthy riparian condition as a key component or touchstone to achieving healthy floodplain conditions necessary to protect, restore and enhance tribal First Foods for the perpetual cultural, economic, and sovereign benefit of CTUIR. Use of locally adapted plant stocks helps protect the ecological integrity of the local plant communities while improving overall floodplain health and fish production potential.



The TNPN also makes native plants available to the local community. Participants in Pollinator gardens through the NRCS or riparian restoration through CURB projects are guided through the process. Many however, are interested in utilizing native plants for beauty, as wildlife attractants, and water conservation. TNPN personnel listen to the objectives of the homeowner to provide plants that will meet their needs and will suit the conditions of their location. The merits and needs of each species are discussed and suggestions are given to increase the success of those plantings.
