What is the difference between a bog and a fen? How does peat form? And what is the story behind the broad, flat valley south of Bonaparte Lake?
Those were some of the questions explored on March 11, 2026, during Life in a Peat Wetland: Bonaparte Meadows, a special OkaKnowledgy presentation hosted by Okanogan Land Trust at the Community Cultural Center in Tonasket.
The presentation brought together local experts to share different parts of the Bonaparte Meadows story. Together, the presentation helped deepen the community conversation around this rare wetland landscape.
A Rare Kind of Wetland
Bonaparte Meadows is a calcareous, or alkaline, fen. These are among the rarest wetland types in the United States, and the Okanogan Highlands are home to several of these unique places.
Unlike bogs, which are mostly fed by rainwater and tend to be more acidic, fens are fed by groundwater moving through the landscape. In calcareous fens, that groundwater carries dissolved minerals from surrounding soils and bedrock, creating alkaline conditions that support specialized plant communities.
These unusual conditions are part of what makes Bonaparte Meadows so ecologically important.
A Landscape Shaped Over Time
The presentation helped tell the story of Bonaparte Meadows from several angles.
The geology of the area helps explain the broad, flat shape of the valley and the conditions that allowed peat to form. The botany reveals a plant community adapted to wet, mineral-rich conditions. The human history of the site adds another layer, showing how people have used, altered, and valued this landscape over time.
Together, these perspectives helped show Bonaparte Meadows as more than a wetland. It is a living record of water, plants, people, and time.
Understanding Peat at Bonaparte Meadows
The story of Bonaparte Meadows starts beneath the surface, with the peat itself.
Peat forms when plants die in wetlands and break down slowly under watery, low-oxygen conditions. Over time, that partially decayed plant matter accumulates into rich, dark peat soil.
It builds slowly. Very slowly.
On average, peat accumulates at about one millimeter per year. That means one meter of peat, or roughly three feet, can represent about a thousand years in the life of a wetland.
That slow process does important work for water, wildlife, plants, and the climate.
Peat soils can hold tremendous amounts of water. During wet seasons, they soak up water and keep it on the landscape instead of letting it run off and away. In drier months, that stored water is released gradually, helping even out stream flows through the year.
Peat wetlands can also help absorb sudden pulses of water from snowmelt, heavy rain, or post-wildfire runoff. In this way, peatlands help soften the impacts of both drought and flooding.
Peat formation also stores carbon underground.
As plants grow, they pull carbon dioxide from the air. When those plants die, much of that carbon would normally return to the atmosphere as they decompose. But in a peat-forming wetland, the wet, low-oxygen conditions slow that decomposition.
The carbon remains locked in the peat, where it can stay for centuries or even thousands of years, unless the peat is dried out or disturbed.
Why Peatlands Need Protection
Around the world, peat wetlands have been drained for farmland, altered by development, and mined for commercial garden products.
When peatlands are damaged, the benefits they provide to wildlife, water, the wider landscape, and the climate can be lost.
At Bonaparte Meadows, protection and restoration go together. Although the site has been affected by both human use and natural disturbance, it still holds extraordinary value for rare plants, wildlife, water, and the surrounding landscape. It also holds tremendous potential for restoration.
Protecting Bonaparte Meadows means protecting more than what we see on the surface. It means safeguarding the deep peat below, the water it holds, the wildlife it supports, and the slow, natural process that makes this place so rare.
