Guess it’s lost in translation.

Conservation land is a protected wild area. Sometimes it’s what we refer to as “the woods,” and not properly marked from a local standpoint.

In my region, there are many county and state (vs federal in US) parks, with recreational areas and rules about how to interact with the wildlife. Greatparks.org.

There are also private nature preserves, and those appear to us as hiking trails. www.cardinallandconservancy.org is an example.

There are also smaller conversation areas. I know of a little bog about the size of a football field with a little sign saying it is maintained by the local college.
