Fonds consists of documents spanning Bunce’s career in the forestry sector, covering both his paid and volunteer work. The bulk of the material relates to his work as a forestry consultant at Reid, Collins & Associates and his work on several national forestry committees. Additional material relates to his years as a graduate student, his early career, his involvement with various professional associations, and his years as part owner of a woodlot near Maple Ridge, BC. Also included are articles he published and notes from presentations that he gave.

The archivist removed some documents that had come with the original donation, but that did not have significant value. These included duplicates, published material available elsewhere, personal documents (such as hotel reservations and journal subscription receipts), and loose documents that had no context. Also removed were documents that contained personal and/or confidential information, such as school transcripts of individuals besides Bunce and private documents of company's for whom Bunce did consulting work.

Some works that Bunce had collected, but not authored, were removed from this fonds and added to the library’s general collection.
