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.

The fonds consists of records which document the origins of SDRI and reflect its activities during its first five years of existence, and includes correspondence, reports, minutes, financial records, and published materials. It is arranged in five series (Central Files, General Correspondence, UBC Correspondence, Subject Files, Research Projects) and one sous-fonds ("Women and Sustainable Development: Canadian Perspectives" Conference).

The fonds consist of reports from field surveyors submitted as applications to designate areas in British Columbia for protection. The fonds also contains supporting records relating to the wider Ecological Reserve program and include correspondence, progress reports, presentations, memorandums, lectures, briefs, surveys, "dead applications", news clippings, Orders of the Lieutenant in Council [photocopies], pamphlets, check sheets, aerial photographs, park proposals, handwritten notes, and meeting minutes. Also included is a small series of records relating to Vladimir Krajina, including; general correspondence, curriculum vitae, a list of publications, articles, newspaper clippings, notes, a legacy biography and obituary.
The archivist restored the original order where it was definitive. However, Ecological Reserve Applications 1-39 can be found scattered throughout the supporting records series. The original record keeper appears to have created a filing system beginning at the Ecological Reserve Application 40 (Petitot Rivers).
