Data-driven bird conservation project takes wing

Michigan State University and the National Audubon Society are teaming up to help protect declining bird populations across North America.

With $1.3 million from a collaborative National Science Foundation grant, the team will develop statistical models fueled by four massive data sets to evaluate how climate change and land use are affecting hundreds of bird species.

Using this understanding, the team will develop forecasts about future responses of bird populations, enabling conservationists and wildlife managers to pinpoint where individual species may be most at risk and identify opportunities to protect these charismatic creatures and all that they do for us.

“People love birds and love looking at birds, but they do so much more that we don’t think about or appreciate as much,” said Elise Zipkin, an associate professor in the Department of Integrative Biology and MSU’s lead investigator on the NSF project. “Birds provide a ton of ecosystem services that are worth billions of dollars, including nutrient cycling, pest control, seed dispersal and pollination.”

Joining Zipkin’s Quantitative Ecology Lab is the Geospatial Laboratory at MSU, led by Andrew Finley, a professor in the Department of Forestry and the Department of Geography, Environment and Spatial Sciences.

Together with MSU postdoctoral researcher Jeff Doser, who

will lead model development, the researchers have a breadth of expertise in aggregating large amounts of biodiversity data from disparate sources.

Working with Audubon, the MSU researchers have a partner that’s a leader in putting scientific approaches to work in bird conservation.

“Broadly speaking, our results will help with conservation planning for avian species and communities,” said Zipkin, who is also the director of the Ecology, Evolution and Behavior program, or EEB, at MSU. “Our models will reveal which areas are likely to be bad for birds in the future and which areas are likely to be climate refugia. We can use that

information to make decisions about where to target conservation efforts so that they are most effective.”

Researchers estimate that, in terms of overall population size, North America has lost more than 3 billion birds over the last 50 years. The trends continue to be concerning today, largely due to a warming planet and humans developing land in ways that damage natural ecosystems.

Researchers have been working to understand how different bird communities in different locations are responding to climate change and land-use changes. Historically, though, those two factors often have been studied separately, said Sarah Saunders, Audubon’s lead investigator on the project.

To deliver those robust forecasts, the team will combine information from four giant databases that document bird abundance and diversity at different locations at different times.

Three of those data sources are maintained by government agencies, including NSF’s National Ecological Observatory Network, the National Park Service Inventory and Monitoring Program and the North American Breeding Bird Survey, which is a partnership between the U.S. Geological Survey and the Canadian Wildlife Service.

The fourth data set is provided by eBird, a collaborative online database managed by the Cornell Lab of Ornithology that enables anyone to submit bird sightings.

These diverse data sets, combined with the team’s modeling work, will enable the researchers to provide a comprehensive picture of the impacts of climate change and land use over the past several decades. They’ll also be able to share that picture on a large scale and with a high enough resolution to zoom into smaller areas.

“By integrating all that data together we’ll have a much better idea of what’s going on with birds in the past and going into the future,” Zipkin said.

The team’s models and forecasts will bring a new level of understanding to the unique challenges faced by birds that migrate and cover large ranges, the researchers said.

Take the American redstart as an example, a warbler that spends the warmer months nesting in the eastern U.S. and Canada. In the winter, however, this species heads south to the Caribbean and as far as Central and South America.

The impacts of climate change and how people use land are not uniform throughout the entire range of a particular species. Researchers need to consider what’s happening at various locations throughout that range to forecast what the future looks like for American redstarts and other migratory species.

“We need to think about how variables are affecting species in different places over a large scale,” Zipkin said. “The effects may not be the same everywhere.”
