The Pinelands includes land in all of the following counties except:

The Pinelands, also known as the New Jersey Pinelands National Reserve, is a significant ecological and cultural region that spans several counties in New Jersey, primarily known for its unique pine forests and preservation efforts. The counties that fall within the Pinelands include parts of Burlington, Atlantic, and Ocean counties. Monmouth County, however, does not comprise any part of the Pinelands National Reserve, making it the correct choice in this context.

The designation of areas within the Pinelands is due to the unique natural resources, landscapes, and habitats that exist there, which is strategically managed to balance environmental preservation with sustainable development. Monmouth County does not share these specific characteristics as a designated part of the Pinelands, confirming that it is the exception among the listed counties.
