Fonds consists of records which reflect Brink's participation on the Environmental Assessment Panel (1973-1983) and The Nature Trust (1984-1987). The papers include material arranged in the following series: correspondence, teaching and research. The papers also include reference booklets and pamphlets. Each series is arranged in chronological order. The records primarily contain one large correspondence series from 1953 to 1975, with bulk dates of 1961 to 1971. The correspondence contains Brink's faculty papers intermingled with the Division of Plant Science's central office files.
