Request for Quotations: Plan for a Limiting Factors Analysis of Chinook Salmon in the Trinity River Watershed

Deadline for Submission of Materials:  August 18, 2023


The National Fish and Wildlife Foundation (NFWF) invites interested professional service providers to submit statements of quotations to develop a Study Plan for a Limiting Factors Analysis (LFA) in collaboration with the Trinity River Restoration Program. 


NFWF is the largest private conservation grant-maker in the nation and is dedicated to sustaining, restoring and enhancing the nation’s fish, wildlife, plants and habitats for current and future generations. NFWF advances these ideals through innovative public and private partnerships, and by investing financial resources and intellectual capital into science-based programs designed to address conservation priorities and achieve measurable outcomes.

NFWF has invested in conservation and restoration projects in the Trinity River Basin of California in partnership with U.S. Bureau of Reclamation (Reclamation) and the Trinity River Restoration Program (TRRP). TRRP restoration actions correspond to an increase in the number of salmon smolts naturally produced within the Trinity River Watershed (Pinnix et al. 2022). However, no similar increase in returning adult spawners has been detected. While natural spawner populations have cycled over the duration of TRRP, numbers of returning fish are currently low (CDFW 2023). To understand this apparent disparity, a Limiting Factors Analysis (LFA) for Chinook Salmon (Oncorhynchus tshawytscha) below Lewiston Dam was identified as a top priority for TRRP (Pickard et al. 2023).

The primary purpose for this Request for Quotations (RFQ) is to identify contractors who are interested and qualified to develop an LFA Study Plan that expands upon TRRP’s scientific knowledge and experience with state-of-the-art methods and analyses to identify and rank limiting factors. TRRP may provide several scientists to participate as additional members of the Planning Team. Interaction between the Planning Team, TRRP scientists, and the TRRP Science Advisory Board is expected to be iterative as background information for the LFA is developed. A separate and subsequent RFQ will be issued to obtain a Study Team with relevant expertise to conduct the LFA in accordance with the Study Plan.

The selected contractor will be requested to provide the following deliverables:

  • Refined life cycle diagram (due prior to the kick-off meeting for TRRP review). 
  • Lead and participate in one day-long project kick-off meeting with TRRP scientists.
  • Electronic copies of all presentation materials or handouts used for the meeting, plus a meeting summary that lists information obtained from TRRP participants.
  • Draft LFA Study Plan, with 3+ level of effort options, in electronic Word format;
  • Final LFA Study Plan, with 3+ level of effort options, in electronic Word format and 508-compliant PDF.
  • Notes on any rejected review comments.
