The fish, animals, and birds which may be found at the site are another interest. Fishing interest calls for a check of the species found, quantity and size, the season they are available, and the stocking program of the fish commission. Animals may be present at the site or provide hunting in nearby areas. The site may be on one of the major flyways of migratory birds or have its own resident bird life. Clams, crabs, and other marine life may add interest at coastal areas.

Each area has its own historical interests with which much can be done. Park visitors are always eager to learn more about the area they are in. The historical sign tells its story, but nothing gets interest across as well as some of the original historical items or places themselves which still have the character of the period covered. Notice should be taken of unusual rock formations, deposits, or shapes of the earth's crust in your region. Those which tell a story of the earth's formation in each area can add geological interest to the recreation sites. An old shipwreck, a high dam, an old covered bridge, a place to find agates or other semi-precious stones or a place to pan gold, etcetera may be of interest. Some areas may provide archeological values such as ancient Indian village sites or hunting areas, caves, artifacts, etcetera.

How well can the site be developed? Look at the physical features of the land to determine how desirable it is for use, what can be done to correct the faults, and what it will cost to make the area meet your needs in comparison to other sites. Many things need to be checked.
