Intended for the lay person and taught at the college freshman level, these evening courses are open to anyone at least 18 years old. Individual courses are useful to professional and amateurs alike in acquiring knowledge of specific subject matter and enhancing enjoyment of the out-of-doors.

The Natural History Field Studies curriculum has been designed to provide participants with a comprehensive and stimulating overview of the regions natural history and conservation issues and applications with an emphasis on learning in the field. A Certificate of Accomplishment is awarded for completion of a required curriculum of 39 Continuing Education Units (CEUs) taken in five subject areas. (See chart below for course requirements/options.

We may not have the Rockies in our back yard, but we have the roots of mountains that were as high as the Alps. Although local earthquakes are rare now, this area broke in two twice and oceans flowed in. Central Atlantic geology tells a story as fascinating as any place on the planet. Course lectures introduce the landscapes, subsurface structures and geologic history of our region. Two field trips emphasize the recognition of local landforms and of the geological processes that created them. ACE College Credit Recommendation Service Reviewed. There will be no class on March 12.

The field identification of rocks requires knowing how to conduct a simple chemical test, recognize six common minerals, and distinguish about ten aspects of rock texture and appearance. In this course, we will learn these skills and then apply them systematically to identify the twenty-five or so types of rock common in the Mid-Atlantic. A hand lens or magnifying glass with a magnification of 6 to 10x is required.

Winter unmasks nature, revealing our local woody plants in their most skeletal form.  Students will learn to identify trees and shrubs by studying the “bare bones” of plants – branching structure, bark, buds, and leaf scars.  Classroom lessons and three mandatory field trips will help students develop observational skills and use clues such as persistent and fallen fruits and leaves, aromatic twigs, and habitat to identify trees in the winter landscape. You must be able to attend all three field trips to successfully complete the class.

Required Reading:

  1. Grimm, William C., The Illustrated Book of Trees, Rev. ed. (by Kartesz, John), Mechanicsburg, PA: Stackpole Books, 2002.
  2. Harlow, William M., Fruit Key & Twig Key to Trees & Shrubs, Mineola, NY: Dover Publications, Inc., 1959.
