Willamette River Initiative Evaluation Report

This report provides an in-depth evaluation of the impact of Meyer Memorial Trust's Willamette River Initiative. It focuses on changes the WRI had on the people, organizations and systems at work toward a healthier Willamette River system. Additionally, four case studies take a deeper look into the WRI's greatest areas of impact:

Approach to Funding case study

Fostering Collaboration case study

Diversity, Equity, and Inclusion Cohorts case study

Within Our Reach Conference case study

Willamette River Planning Atlas

This document, the result of work by more than 30 researchers over five years, identifies three possible scenarios for how land and water use in the Willamette Basin may change by the year 2050 and evaluates each scenario for its effect on the ecosystem. The conservation scenario sets goals for needed increases in floodplain forest and side channels and alcoves by the year 2050 to achieve river health.

Willamette River Report Card

The report card offers a baseline assessment of the river’s health from headwaters to mouth, with specific scores for key vital signs such as water quality, habitat availability, and presence of key fish and wildlife populations. It also includes individual grades for the lower, middle and upper reaches of the river.

The State of Diversity in Environmental Organizations: Mainstream NGOs, Foundations & Government Agencies

This report, compiled from surveys of 191 environmental non-profits, 74 government environmental agencies, and 28 leading environmental grant making foundations, investigates the gender and racial diversity of the environmental movement. The study found a "green ceiling" keeping the environmental movement overwhelmingly white, even as the U.S. population diversifies.

Scientific report: Geomorphic and vegetation processes of the Willamette River floodplain, Oregon

This report is a synthesis of geomorphic and vegetation processes of the Willamette River and its major tributaries. It summarizes the current ‘state of the science’ regarding present-day floodplain processes and also identifies major knowledge gaps that hinder our ability to set realistic targets for future management and restoration activities.

Article: When Local Solutions Aren't Enough: A Strategic Funding Partnership to Restore a Large River System

Freshwater ecosystems are increasingly imperiled, and funders, nongovernmental organizations, community groups, and government agencies worldwide are working to restore ecological function and resiliency to these critical resources. What does it take to structure, support and implement truly effective, broad-scale watershed restoration? This article describes an experimental collaboration aimed at improving the health of the Willamette River system, led by the Meyer Memorial Trust with support from the Bonneville Environmental Foundation and the Oregon Watershed Enhancement Board.

Public Opinion Research: Willamette River Baseline Survey Results

This report summarizes the findings of a telephone survey of 1,000 Willamette Valley residents commissioned by Meyer Memorial Trust to assess community behaviors and perceptions about the Willamette River. The survey sought to establish a baseline of general knowledge, values and perceived threats to the Willamette to inform efforts to engage the public in support of a healthier river.
