Oak Accord

The Oak Accord

How Oregon landowners are protecting threatened white oak habitat


In Oregon’s Willamette Valley, where more than 97% of the white oak’s historic habitat has already disappeared, vineyard and forest landowners have signed The Oak Accord as a way to protect and restore more than 1,500 acres of the Willamette Valley’s fragile ecosystem.

Protecting Oregon’s Oak

With less than 3% of historic oak habitat remaining due to fire suppression, development, and conversion to agricultural land, there is an urgent need to protect the oak woodlands and savannas that still exist. Because 98% of the Willamette Valley’s native oak currently sits on private land, landowners play a critical role in restoring oak habitat in the region. Vineyards are commonly situated in oak habitat because grapes grow well in the soil.

The Oak Accord, a voluntary conservation agreement, was inspired by the vision of local landowners such as Willamette Valley vineyards and forest owners who see the economic and environmental value of native oak habitat and want to play a role in preserving it. In exchange for signing the Oak Accord landowners receive recognition of their conservation commitment, guidance on restoration activities, quantified assessments of the results of their efforts, and marketing tools to help them communicate the conservation work they’re doing to customers, regulators, and colleagues.

Results Underway

The Oak Accord officially launched March 23, 2017, at Sokol Blosser Winery where the founding signatory members — many of which are Willamette Valley vineyards — publicly signed the voluntary conservation agreement.

Willamette Partnership visits every signatory’s property to assess their current level of quality and quantity of their native oak habitat. National eco-friendly wine labels are jumping on board: Salmon-Safe is integrating an oak conservation requirement into their farm certification standards, which are widely used in the wine industry, while LIVE is determining what role efforts to restore native oak habitat might play in meeting their requirements.


“When all of us are doing our part and working toward the common goal, there might actually be a way to change the story that’s written about oak. And the Willamette Valley landowners are going to be the authors of that story.– Nicole Maness, “A Tree Grows in Oregon”

Meet the Signatories

Find out who in the Willamette Valley is making the pledge to protecting oak.

The people and groups who signed the Oak Accord are committed to protecting and restoring oak habitat on their properties. Collectively, their efforts will be key to reconnecting and sustaining a resilient network of oak habitat across the Willamette Valley.

Participation in the Oak Accord is a way for l landowners to demonstrate that management of vineyards and of forestland can take place in harmony with healthy, sustainable oak habitat. The Accord creates a stewardship standard for existing land managers and owners and is also a way to introduce new landowners to the importance of oak conservation.

How to Sign

Learn how to become a part of this movement through three simple steps.

What’s the commitment?

  1. Undertake an assessment of the current (baseline) level of oak habitat quality and quantity on your property;
  2. Avoid and minimize any future impacts to oak habitat;
  3. Mitigate for any impacts that cannot be avoided; and
  4. Undertake a periodic (every 5 years) assessment of oak habitat on your property.

One of the benefits of participating will be access to resources and support that will make meeting the terms straightforward and reasonable. The Oak Accord is a voluntary commitment to protect and restore your native oaks and you may withdraw at any time.

Learn about Oregon’s Conservation Strategy

The Oregon Conservation Strategy is an overarching state strategy for conserving fish and wildlife. It provides a shared set of priorities for addressing Oregon’s conservation needs. The Conservation Strategy brings together the best available scientific information and presents a menu of recommended voluntary actions and tools for all Oregonians to define their own conservation role. The goals of the Conservation Strategy are to maintain healthy fish and wildlife populations by maintaining and restoring functioning habitats, preventing declines of at-risk species, and reversing declines in these resources where possible.
