Great Basin Seed provides post-wildfire seed recommendations for Okanogan County, Washington. These recommendations aim to restore burned landscapes and promote healthy vegetation. The Methow Valley NRCS recommended these seed selections following the Carleton Complex fire. During the 2014 fire season, four relatively small lightning-strike fires in Washington state combined to form the Carlton Complex Fire. It destroyed 353 homes, burned 256,000 acres, and caused an estimated $98 million in damage in Okanogan County. Fire suppression costs the state at least $60 million. It remains the largest single wildfire in Washington State history. In 2015, the Okanogan Complex Fire burned an additional 304,000 acres but did not combine into a single fire.
Though the Carleton and Okanogan Complex fires have long since been extinguished, landowners in more recent fires have found these mixes to be helpful and effective. We will continue to offer these seed mixes as long as fires burn in the West, and as a reminder of the heroic and herculean efforts of land owners, firefighters, emergency service personnel and anyone who assisted in the recovery process.
Suggestions from us:
- Don’t be afraid to plant a combination of natives and non-natives or a combination of mixes. The diversity buys you a little insurance.
- If these mixes do not meet your needs for whatever reason, please call and we will help you formulate a mix with you.
- Consider planting shrubs and flowers with your grass mixes! We have included recommendations below.
