HISTORICAL RECORD a The Virgin Islands National Park is characterized by modified plant and animal communities. An understanding of the changes that have occurred in the past and are occurring today is desirable in appraising and interpreting the successional changes that are now leading toward a climatic climax. The following outline is an approach in gathering these historical date. Objectives: 1. Define, establish, and maintain pre-Columbian condi- tions. (Early Danish culture, however, should be preserved for historical record.) All natural arrivals of plants and animals should not be interferred with. 2. Instigate interpretive program emphasizing the philosophical trans- lation of the functions of insular areas and the laws of succession, rather than the enjoyment of the park by physical recreation. Pre-Columbian conditions: 1. Analyze the past geological history and establish a sequence of events leading to pre-Columbian period, including structural and physiographic changes, climates, and fossil evidence. 2. Define the ecological community existing just prior to the arrival of Columbuse ae Compile information from early Danish pictures, documents, journals, Carib-Arawak legends, mythology, significance of petroglyphs and
