In addition, the analyses will help to evaluate regulations and indicate if new or modified regulations are required. Analysis should be continuous so that favorable and unfavorable trends in ecological conditions can be detected in time to prevent undesirable, permanent degradation. Any material not occurring naturally at Butler Head will be considered to be rubbish. Natural materials that may occur elsewhere will be considered rubbish if they do not occur naturally at Butler Head or in Butler Cove. Accumulated rubbish will be removed, with periodic and ad hoc activities to keep Butler Head clean.
Natural debris consists of products of indigenous flora and fauna and geological upheaval.
Fallen trees, leaves, driftwood, rocks and other natural debris may be relocated to permit use of trails and other facilities but may not be removed from Butler Head. Although the natural condition of Butler Head is forested, the field will be reclaimed and maintained in its present condition. Attempts will be made to eradicate European purple loosestrife because of its tendency to crowd out and replace native species. Formal, detailed, amateur surveys will be made of roads, trails, boundaries, archeological and other features. These surveys will supplement and add detail and precision to the data contained in the Appendixes.
