Iowa conservation group close to securing unique wetland in Grimes and Granger

• "To be able to get a parcel that size in the Des Moines suburbs is really rare," he tells Axios.

Driving the news: INHF, a nonprofit that works to conserve land, is in its final push to raise $8 million to transfer the slough to Polk County Conservation, which will build out trails and open it to the public.

• The group purchased the land in 2023 and holds it while funding is figured out.
• They hope a fundraiser Thursday will get them closer to raising the last $2 million

What it is: A slough, which rhymes with "grew," is a shallow swamp that usually backs up to a larger body of water.

• Brenton Slough is one of only 15 in the state and connects with the nearby Beaver Creek. Its deepest point is just 3 feet.

How it started: The property was a game refuge for the Brenton family in the early 1900s. The family decided to preserve the land and agreed to sell it to INHF in 2023.

State of play: With the influx of money, Polk County Conservation will focus on wildlife preservation, adding hiking paths, bird-watching spots and educational events.

• The county agency also plans to install a mixed-use trail that will connect to the region's larger trail system.

What's next: INHF is hosting Paint the Park from 5-7pm Thursday with a live painting and musical performance from Chad Elliott at the slough.

• The event is free with a suggested donation of $25 per person. People may also donate online.
