The Williamsburg Forest Conservation Area is an important headwater feature to the Hoasic Wetland Complex, with 12 acres of provincially significant wetland (PSW) and 320 acres of locally significant wetland. 
The interior lowland forest provides prime bird and waterfowl habitat. The total 400 acres also includes 25 acres of spruce plantations.
Since 1961, the property was managed by the Ministry of Natural Resources and Forestry and came under management by the Municipality of South Dundas from 1995 until 2014. Talks with South Nation Conservation began to assume ownership and management in 2013. Through community support, the property locally known as “the 400” was officially transferred to SNC in 2014 and opened as the Williamsburg Forest Conservation Area. The property will continue to provide recreational opportunities to the public. Local hunters are reminded that a letter of permission is required from SNC to hunt on any SNC properties. SNC is grateful that the Municipality of South Dundas decided to preserve this property in perpetuity.
