Research At The Arboretum
The Holden property encompasses extensive high-quality natural forest ecosystems (~3,000 acres) and conducting nationally recognized research in plant and environmental sciences while fostering the next generation of scientists is a key part of our mission. Thus, improving our fundamental understanding of the function and dynamics of native forests and how they respond to environmental change is another focus of the Arboretum’s Research program.
Our scientists, post-doctoral scholars and graduate students conduct basic and applied research in the following areas.
Using traditional plant breeding methods, researchers at the Arboretum are transferring disease resistance from wild rhododendron species to hybrid varieties that are grown as ornamental plants in gardens. The increased root rot resistance has also enabled these plants to be grown in much warmer climates (e.g. the Gulf South) where the root disease pressure is greater.
The 900+ species of Rhododendrons in the world originate from habitats ranging from sub-tropical to sub-arctic. Rhododendrons also have a broad diversity of leaf types.
Research in Rhododendron physiology at the Arboretum focuses on how leaf diversity relates to the evolution of habitat diversity.
Our ecological research mission is focused on contributing to a better understanding and conservation of the diversity, health and function of natural forest ecosystems in Northeast Ohio.
Forest ecology research at Holden examines the mechanisms by which organisms tolerate environmental change and the importance of biological diversity to the function of forests.
Researchers and students at the Arboretum are discovering what environmental factors affect soil fungi and bacteria and how these soil organisms affect plant growth. Research studies examine how human activities like climate change and air pollution can harm these beneficial soil organisms. Healthy soil and healthy soil food webs are important to conserve our natural areas and agricultural systems for future generations.
Based at Cleveland Botanical Garden, the goal of the urban ecology research program is to develop reuse strategies for vacant urban land and understand the social and environmental impacts of such strategies. The program studies low-cost, low-maintenance methods of stormwater management and neighborhood stabilization.
