Starting this year, Sunny Valley Preserve’s Open Farm Day will move to a biennial format.

This means the event celebrating Connecticut’s farming and conservation heritage will next be held in September 2019.

There will be no Open Farm Day at Sunny Valley Preserve this year.

“Open Farm Day is a community tradition that’s made possible by generous sponsors, volunteers and the thousands of people who attend it,” said Wayne Woodard, preserve manager at Sunny Valley Preserve.

“We’re deeply grateful to everyone who has been part of this event, and we can’t wait to see them again in fall 2019,” he said.

“Holding the event every other year rather than annually will make it more special,” Woodard said. “This format will also help preserve staff plan and host an even more exciting event, while tackling the day-to-day work of making Sunny Valley the best preserve it can be.”

In 2017, more than 2,000 people attended the 25 annual Open Farm Day.

Sunny Valley Preserve was founded in 1970, when George D. Pratt Jr. donated multiple parcels of agricultural and natural lands to The Nature Conservancy.

One condition of Pratt’s gift is that the farms be kept in agriculture as long as possible.

Today, about 650 acres of the 1,850-acre preserve on the Housatonic River are in active agriculture.

The farms, leased by independent farmers, are privately-operated businesses. The farmers grow diverse crops and sell most products locally, providing locally-grown food and enhancing the local economy.
