Today’s post comes from Dr. Gail Langellotto (Oregon State University Department of Horticulture) introducing her new research team and future citizen science opportunities.
Gardens are unique and understudied systems, that can have multi-faceted and positive impacts on environmental and public health. But, key to realizing the potential, positive impact of gardens are the decisions that are made when planning, installing and maintaining garden beds and features. These decisions are especially important, because gardeners manage and maintain a significant amount of land in the United States. Take lawns, for example. Studies suggest that lawns represented the single largest irrigated crop in the United States, and that there are more acres of lawn than the combined acreage of corn, alfalfa, soy, orchards and rice1.
Of course, lawns are just one component of a garden ~ perhaps the least interesting component, from an ecological point of view. Gardens are special, because of their unique levels of plant abundance and diversity2, which in some cases can be considered ‘biodiversity hotspots’3. In New York, my lab group documented the important role that plant abundance and diversity in urban and suburban gardens can play in conserving pollinator biodiversity4, 5, 6. Recently, some of the top researchers in the country argued that conservation plans could better harness the positive environmental benefits of gardens and landscapes7. But, before we can get there, we need to answer some basic questions.
This is where the Garden Ecology Lab comes in. Our group works at the interface of ecology and sociology, to try and understand the benefits of gardens to the environment and to human health and well-being. We want to document the biodiversity of plants, pollinators and other organisms in Oregon gardens, and analyze what factors constrain or promote garden biodiversity. I’ve done this work in New York, but want to repeat these first steps in Oregon. Ultimately, the goal is to understand how gardens ~ and the decisions we make in our gardens ~ either promotes or constrains ecosystem services, such as pollination, pest control, and more.
Our group is diverse, and includes students interested in ecology, horticultural therapy and urban soils. Extension and outreach is embedded in all that we do, such that we plan to work closely with gardeners (as citizen scientists) to describe and understand garden biodiversity, and to communicate findings to broader audiences. We’ll be looking for garden study sites and cooperating gardeners in the coming months, and invite you to get to know us, just a bit more.
Gail Langellotto (Principle Investigator): An entomologist by training, Gail coordinates the statewide Master Gardener program. Her research and extension interests are focused on developing a better understanding of how to design and manage gardens and parks within urban/suburban landscapes to maximize ecosystem services such as pollination, pest control and human health and well-being. Starting in 2017, she hopes to work closely with Master Gardeners in home and community gardens, to begin documenting garden biodiversity in Oregon.
Michael Nelson: a student of the Earth, Michael has begun his Master’s of Horticulture to further his desire to create a sustainable community of alternative learning and living. He is interested in community gardening, how private growers overcome their hurdles, and fostering the abundance possible if we all networked together to create our own food.
Robert Yarnall: Robert has an innate drive for social justice. He has begun his Masters of Arts in Interdisciplinary Studies in which he has chosen to integrate three academic disciplines: Horticulture, Food Culture in Social Justice, and Business. His ultimate goal is to study the effectiveness of therapeutic horticulture on inmates and staff within Oregon’s correctional facilities, while also highlighting the economic benefits associated with such programs.
Signe Danler, a lifelong gardener and plant nerd, brought her passion for plants to OSU and earned a Masters of Agriculture degree in 2014. Her wide-ranging interests were fulfilled by coursework in Horticulture, Urban Forestry, Environmental Science, and Soil Science. Her particular area of focus is urban horticulture and applying ecological principles to landscape design and maintenance. She is now teaching sustainable gardening as instructor of the online OSU Extension Master Gardener course, and designing ecologically sensitive gardens as a landscape designer.
Aaron Anderson is a M.S. student broadly interested in how ecological function can be incorporated into urban and agricultural landscapes. After dabbling in entomology, restoration ecology, and biological control, he became interested in studying urban systems. Aaron is fascinated by native beneficial insect conservation, especially in understanding how such species use urban green spaces as habitat to in turn inform how we manage these areas.
