The W. Carter Johnson Papers present a comprehensive account of ecological research spanning diverse ecosystems and geographical regions, organized into distinct series.

The Blue Jays series delves into the behavioral patterns of blue jays, focusing on caching and consumption behaviors related to acorns. Through meticulous field studies, Johnson examines how blue jays manage acorn tannins, cope with weevil-infested nuts, and contribute to forest regeneration through seed dispersal, highlighting their vital role in shaping forest ecosystems.

In the Forests/Trees series, the focus broadens to encompass broader forest ecosystems, emphasizing woodland restoration, forest succession, and management strategies. Various case studies within this series explore topics such as the impacts of natural disturbances like ice storms on forest dynamics, the effectiveness of restoration efforts in maintaining pine-oak forests, and the factors influencing tree recruitment in fragmented landscapes and riparian zones. Through detailed analyses and historical perspectives, researchers highlight the complexities of forest ecosystems and underscore the importance of ecological restoration for ensuring their long-term sustainability.

The Mortensen Ranch series offers a detailed account of land management and restoration efforts, documenting historical research, restoration projects, and visual progress through photographs and digital images, showcasing the ranch's commitment to sustainable practices. From regrowth of wooded draws to mitigation of flood impacts, the documents highlight the ranch's dedication to ecological balance and conservation excellence.

The Platte River series provides a comprehensive examination of the river's ecological, geological, and historical aspects, contributing valuable insights into its dynamics and ongoing conservation efforts. Spanning surveys, scientific research, professional activities, and historical records, this series offers foundational data on the river's islands and surrounding areas, investigating vegetation changes over time and informing management strategies for preserving its ecological integrity.

The Prairie Wetlands series focuses on wetland ecosystems within the North American prairie pothole region, addressing ecological, management, and conservation challenges posed by climate change. Studies provide insights into wetland structure and function, with a particular emphasis on specific sites and long-term dynamics, offering valuable resources for informing adaptive management strategies and conservation efforts.

The Snake River series covers extensive research and environmental studies conducted along the Snake River in Idaho, informing conservation efforts and sustainable management practices. From detailed reports on specific projects to field notes and vegetation sampling methods, this series offers a wealth of information on the river's ecosystem dynamics and management challenges.
The Rivers/Lakes series offers a wealth of research and data on various river and lake ecosystems, contributing to a deeper understanding of their dynamics and informing management strategies. Covering topics such as hydrology, vegetation, and wildlife, this series serves as a valuable resource for conservation and management efforts in aquatic ecosystems.

Material in the Russia series sheds light on scientific collaboration, research activities, and environmental initiatives in the Soviet Union, fostering international cooperation in ecological research. Key elements include correspondence detailing exchange visits, translations of scientific literature, and reports on Soviet ecology, enriching our understanding of Russian ecology and environmental science.

Beyond specific research topics, the collection also showcases the personal and professional contributions of Carter Johnson, underscoring his commitment to environmental stewardship and ecological preservation. Overall, the W. Carter Johnson Papers serve as a valuable resource for researchers, educators, and conservationists, providing a rich tapestry of ecological knowledge and environmental stewardship practices aimed at safeguarding natural heritage for future generations.
