About National Prairie Day
National Prairie Day is observed on the first Saturday of June each year, falling on Saturday, 5 June 2027. The day recognises North America’s prairie grasslands, one of the planet’s most biodiverse and most endangered ecosystems, and encourages the public to learn about prairie conservation, restoration and the wildlife that depends on this vanishing habitat.
What is National Prairie Day?
National Prairie Day is an annual observance dedicated to the tallgrass, mixed-grass and shortgrass prairies that once stretched across the heart of the continent. It was created to educate people about why prairies matter, to celebrate the species that call them home, and to rally support for protecting and restoring the fragments that remain. The day was founded by the Missouri Prairie Foundation, a conservation organisation that has worked to protect native grasslands for decades, and it speaks to anyone who cares about biodiversity, clean water, healthy soil and the natural heritage of the Great Plains and Midwest.
When is National Prairie Day?
National Prairie Day falls on the first Saturday of June every year. In 2027 it will be marked on Saturday, 5 June. Because the date is tied to a weekday rather than a fixed calendar date, it shifts slightly each year. The table below shows the dates for the next several years so you can plan ahead.

Why National Prairie Day Matters
The loss of North America’s prairies has been catastrophic. An estimated 140 to 170 million acres of tallgrass prairie once covered the continent, and roughly 99 percent of it has been lost, mostly ploughed under for agriculture during the nineteenth century and the development that followed. That makes tallgrass prairie the most endangered terrestrial ecosystem in North America, with surviving remnants clustered in pioneer cemeteries, railway rights-of-way, steep river bluffs and a handful of protected reserves.
Prairies are not empty space. A single native prairie can contain hundreds of plant species, supporting pollinators, ground-nesting birds and grazing mammals in a web of life as intricate as any rainforest. They store carbon in deep root systems, filter and recharge groundwater, and buffer against floods. As grasslands disappear, so do the creatures that rely on them: the U.S. Fish and Wildlife Service has proposed the regal fritillary butterfly for endangered listing after the loss of 99 percent of its habitat, and greater prairie-chickens, whooping cranes and prairie fringed orchids face similar pressure.
How to Get Involved in National Prairie Day
There are many ways to mark the day, whether you live beside a remnant prairie or in a city flat far from open grassland.
- Visit a prairie reserve – Many states maintain protected prairies open to the public. Walking through native grassland in early June, when wildflowers are in bloom, is the best way to understand what is at stake.
- Plant native species at home – Even a small garden bed of native grasses and wildflowers provides food and shelter for pollinators and helps reconnect fragmented habitats.
- Support a prairie conservation group – Organisations such as the Missouri Prairie Foundation rely on donations and members to acquire and steward land. A small contribution helps protect acres of habitat.
- Volunteer for a restoration project – Seed collection, invasive species removal and prescribed burns all need willing hands. Local conservation groups often run volunteer days around this time of year.
- Learn to identify prairie plants – Pick up a field guide or use a plant identification app to learn the difference between big bluestem, compass plant and purple coneflower. Knowledge builds appreciation.
- Spread the word online – Share photographs, facts and conservation links on social media to reach people who have never thought about grasslands.
- Reduce your lawn – Replacing part of a manicured lawn with native plantings cuts mowing, saves water and creates pocket habitat that supports prairie wildlife.
- Attend an educational event – Nature centres, museums and botanical gardens often host talks, guided walks and family activities to mark the day.
History of National Prairie Day
National Prairie Day was established in 2015 by Christine Chiu of the Missouri Prairie Foundation. The foundation, which has championed grassland conservation for many years, recognised that prairies lacked the public profile of forests, wetlands and oceans despite being far more imperilled. The aim was straightforward: to give the prairie a day of its own and to drive education, conservation and restoration.
The choice of the first Saturday in June was deliberate. By early summer, prairies are alive with colour as grasses grow tall and wildflowers come into bloom, making it an ideal moment to draw people outdoors to experience the landscape first hand. The weekend timing also gives families, schools and community groups the chance to take part without competing with the working week.
Since its founding, the observance has grown beyond Missouri to be recognised across the prairie states and beyond. Nature reserves, botanical gardens, museums and conservation charities now use the day to host guided walks, planting events and talks, building a wider public understanding of why these grasslands deserve protection.
Noteworthy Facts About National Prairie Day
- National Prairie Day was founded in 2015 by Christine Chiu of the Missouri Prairie Foundation.
- Roughly 99 percent of North America’s original tallgrass prairie has been lost, making it the most endangered terrestrial ecosystem on the continent.
- Historically, an estimated 140 to 170 million acres of tallgrass prairie covered North America.
- A single native prairie can host hundreds of plant species, rivalling the diversity of a tropical rainforest at a smaller scale.
- Prairie root systems can reach many feet underground, storing carbon and helping the soil resist drought and erosion.
Frequently Asked Questions
What is National Prairie Day?
National Prairie Day is an annual observance that celebrates North America’s prairie grasslands and raises awareness of their conservation, restoration and the wildlife they support. It was founded by the Missouri Prairie Foundation in 2015.
When is National Prairie Day in 2027?
National Prairie Day falls on the first Saturday of June, which in 2027 is Saturday, 5 June.
Why are prairies so endangered?
Most prairie land was ploughed for agriculture during the nineteenth century, and development has continued to fragment what remains. Around 99 percent of original tallgrass prairie is gone, and much of the surviving grassland is unprotected.
