W. Carter Johnson Papers

200 linear feet (17 record boxes, 1 oversize box, 1 oversize folder) Photographs, Audiovisual material, electronic media

The W. Carter Johnson Papers document ecological research and related professional activities from the 1960s through 2017, with most material dating from the 1970s through the 2000s. The collection is organized into subject and project groupings that reflect Johnson’s research program, including blue jay seed dispersal and nut caching studies, forest and tree ecology, prairie wetland ecology, and riparian vegetation research on major river systems. Records include field notes, data sets, statistical analyses, research proposals and prospectuses, conference materials, correspondence, photographs, slides, maps, and related publications and reprints.

A substantial portion of the collection focuses on blue jay mediated dispersal of acorns and beech nuts, including field notes dating from 1976 to 1989, data sets from Wisconsin, Virginia, and Iowa, banding records, artificial cache and germination data, and analyses of dietary responses to tannins and weevil infestation. Forest and tree ecology files address forest dynamics, succession modeling, regeneration and recruitment, biomass and carbon storage, and restoration case studies, with coverage of pine oak systems, disturbances such as ice storms, and seed dispersal in fragmented landscapes. Prairie wetland materials document long term study of prairie pothole wetlands, including hydrology, vegetation sampling, seed bank composition, and simulation modeling related to climate variability and climate change, with extensive site level data and photographs from locations such as the Deuel semipermanent wetland and the Severson Waterfowl Production Area.

Riparian and river focused research is represented through extensive Platte River documentation that includes multiyear monitoring and demographic studies of cottonwood and willow, GIS products, graphs, maps, field notes, reports, and large sequences of labeled slides spanning the mid 1980s through the early 2000s. Complementary river research files address the Snake River in Idaho, including Swan Falls related vegetation studies, sampling methods, progress reports, maps, photographs, and slides. Additional series document work on the Missouri River and other rivers and lakes, as well as international scientific exchange and translated materials concerning Soviet and Russian ecology. The collection also includes documentation of the Mortensen Ranch restoration work in South Dakota, including correspondence, interviews, project notes, awards, photographs, and guides related to rangeland and wooded draw restoration.

The W. Carter Johnson Papers documents ecological research methods and findings across multiple ecosystems, with notable depth in long term field data, modeling, and applied studies of seed dispersal, forest succession, wetland dynamics, and riparian vegetation response to regulated river flows. The collection supports research into late twentieth and early twenty first century ecological science, including the development and use of data sets, statistical procedures, GIS products, monitoring protocols, and longitudinal photographic documentation. These records also provide evidence of professional collaboration and scientific communication through proposals, conference participation, correspondence, and exchange activities, offering context for how ecological research informed management and restoration efforts in prairie, wetland, and riverine environments.
