The series comprises Condry's card indexes relating to animal, bird and plant life, topography, geology, ecology, habitats, tourism, travel, landscape history, the author's own diaries, his published works and numerous bibliographic references. Most of them refer to Wales, but some of them are indicative of his interest in African wildlife and plants. Many of the entries are expanded with insertions of relevant notes, correspondence and printed articles, 1930-1998.

The file contains notes (1992-1994) on the locality of Harborne and other places in the West Midlands, plants of Cwm Cau, past inhabitants and plant species of Ynys-hir and Eglwys-fach, the Nature Conservancy Council, the Roman Steps, scenery, plants and birds of named sites in upland Merionethshire, with some entries copied from Condry's nature diaries of July and August 1955, partial, deleted drafts of articles, the meaning of a place name and a list of Cader Idris plants
