The purpose of this guide is to stimulate the development of nature centers. The guide offers possible solutions for common problems which many schools face when considering an on-campus nature center, for example, lack of readily available open space, minimum knowledge of how to develop and maintain an on-campus nature center, and lack of detailed knowledge of how to utilize a nature center. The guide covers such topics as background information, site selection and acquisition, materials acquisition, layout, construction technology, obtaining plants, encouraging wildlife, and planning a curriculum for the nature center. The appendix lists other on-campus nature centers, and individuals who may be contacted for further advice. (TK)
