Parks that fall within this category will typically be state parks or other parks bound by large amounts of acreage & forestry. Examples of this type include Forest Park in St. Louis, Missouri and Babler State Park In Wildwood, Missouri.

Parks that qualify for the midsized or midsized+ category are still quite large, but don't contain as much forestry & vegetation as a large/state park. Midsized+ parks will generally have several key elements and features like the Butterfly House at Faust Park in Chesterfield, Missouri.

Small parks, or 'playground' parks, typically have only a few elements within their boundaries and generally serve as neighborhood parks. An example of this would be DeMun Park located in Clayton, Missouri.

Any park that falls within this category is usually small in size, and possesses commemorative features like that of Veterans Honor Park in Chesterfield, Missouri. Dog parks, which are also generally small in size, will be classified within this group as well.

Although trails & nature reserves come in many different sizes, these parks will most likely include key geographical features like lakes, ponds, & rivers, as well as some forestry and nature paths. An example of this would be River's Edge Park in Chesterfield, Missouri.
