Located on the Norfolk Sand Plain in the Carolinian Life Zone, Norfolk County’s soil type is sandy loam, the most fertile land in Ontario. With a mild climate and lengthy growing season, the region has long been the centre of the Ontario tobacco belt. However, many farmers have begun the process of diversifying their crop selections to include fruits and vegetables, lavender, ginseng, hazelnuts, and wolfberries as tobacco consumption continues to decrease.
A significant natural feature of Norfolk is Long Point, a 40 kilometre (25 mi) spit of land projecting into Lake Erie. It plays an important part in eastern North American bird migration, and was designated a World Biosphere Reserve by UNESCO in 1986. Long Point Provincial Park is located on the point. More than 25% of Norfolk County is considered to be forested; especially near the major communities and hamlets that dot the county.
