The Interpretive Guide was created by Mark Luterra ‘07 as an ENTS capstone project. It describes the history and major habitats of the Arb. The history section begins with bedrock formation 500 million years ago and proceeds through glaciation, presettlement times, Carleton purchase, and changing land use goals. The habitats section describes the ecology of the prairie, oak savanna, upland and floodplain forests, pine plantations, and wetlands, and also provides descriptions of the most common plants and animals in each habitat.
In addition, 49 signs placed along Arb trails mark points of interest and are accompanied by descriptions in the guide.
To print the PDF file as a booklet, set your printer to duplex and flip on short edge. Pages 1-20 comprise the guide, and pp. 21-22 contain a bibliography that did not fit in the printed version. The center spread (page 20) contains an Arb map with locations of all 49 signs marked.
