The golden-winged warbler and the Blanding鈥檚 turtle can thrive in the shallow waters and adjacent dense vegetation typical of swampy marshes in restored wetlands.

In the St. Lawrence River watershed in northern New York, two creatures struggle to hang on in the complex ecosystem of restored wetlands.

The Blanding鈥檚 turtle and the golden-winged warbler can thrive in the shallow pools of water and adjacent dense shrubby vegetation typical of the swampy marshes.

The recovery of these two specific species is an important indicator for an interdisciplinary team of researchers, including two from 黑料不打烊, assessing the viability of public-private partnerships to restore wetlands. Their work is providing answers to ensure conservation efforts that benefit both human and animal in this region鈥攁nd possibly beyond.

The work assesses the results of two government programs in which private landowners, including farmers, voluntarily agree to conservation easements to allow wetland restoration.

鈥淲e know it鈥檚 successful because there鈥檚 a lot of enrollment and a lot less controversy than wetland regulation, which creates pushback and resentment in rural and agricultural communities and hadn鈥檛 worked very well,鈥� says Rick Welsh, a sociologist and professor of food studies in , who is a co-investigator. 鈥淏ut we don鈥檛 know if the outcomes regarding these kinds of natural capital鈥攂iodiversity, water quality鈥攁nd social and economic impacts have been successful. That鈥檚 what we鈥檙e trying to find out.鈥�

Interdisciplinary team

The team鈥攚hich also includes co-investigator Associate Professor of Civil and Environmental Engineering David Chandler in SU’s , and Associate Professor of Biology Tom Langen, head investigator; Biology Professor Michael Twiss; and Associate Professor of Economics and Financial Studies Martin Heintzelman, all from Clarkson University鈥攔eceived a two-year grant from the University of Michigan鈥檚 Water Center for the project.

The research looks at the impacts of programs through the U.S. Fish and Wildlife Service, the U.S. Department of Agriculture Natural Resources Conservation Service and Ducks Unlimited. In the programs, landowners limit development on their lands and at times permit the government to make changes to the property that help draw more biodiversity, such as damming a drainage ditch.

Researchers will measure the ecological, social and economic impacts of 50 of these restored public-private partnership wetlands within the Lake Ontario/St. Lawrence River watershed. Wetlands, such as these, are important for biodiversity, as well as for flood protection and improving water quality.

Researchers hope to develop a framework for assessment of restored wetlands that could be applied to other areas in the region or in the country.

鈥淚n North America the estimates vary but we had filled or drained two-thirds of original wetlands to make farm fields and that has an effect on the stream water quality throughout the country,鈥� Chandler says.

Wetlands help mitigate sediment and manure runoff and these government programs helped support rebuilding of wetlands, Chandler says. The Army Corps of Engineers had been mandated to assess wetlands, but the corps was unable to do most of the assessments before the mandate ran out.

Developing a framework

鈥淲e鈥檇 like very much to see this not just be a one-time project but the development of a cost-effective method that could be applied by us or other teams at least throughout the region,鈥� Chandler says.

That was also important in their grant proposal. 鈥淭he landscapes may differ by ecology and climate, but the framework should be able to at least inform research in other areas of the country and the world,鈥� Welsh says.

Researchers will assess such areas as the diversity of plants and animals; water quality; and property values of those who are participating. One of the scientists, an ecologist, is doing an inventory of species and is particularly interested in umbrella species, such as the Blanding鈥檚 turtle and golden-winged warbler.

鈥淚f there are certain species that live around these wetlands, that shows these areas are providing some complex ecosystem benefits, and ecologists view these species as indicators for the success of the wetland,鈥� Chandler says.

Puddles and trees

Ecologists want to know the variability and availability of the water that feeds the wetland and the topography of the various wetlands, which impacts what will sustain the animals.

鈥淚t turns out that what鈥檚 important to the turtles is having a wide range of puddles and pools that are good for basking and having baby turtles,鈥� Chandler says. 鈥淲arblers like certain types of tree and bush canopy to hide their chicks and easily get to a food source without predators.鈥�

Chandler鈥檚 expertise is in analyzing the hydroperiod, or the amount of time that land is underwater and, in this research, how that changes for different wetland types and what that mean for the various species.

With the grant funding, Chandler, who will be assisted by students in the work, purchased a terrestrial laser scanner that will allow him to create 3D images of the wetlands and the landscape. The information can be downloaded into mapping and design software and reproduced as a digital color image.

鈥淲e are hoping that we鈥檝e found a good way to get an index of typography that would be indicative of what would work well for turtles and birds,鈥� Chandler says, who plans to begin surveying the areas this spring.

Benefits for the landowners

As a sociologist, Welsh is interviewing program participants to discover why they participated, what they perceive as the benefits and how satisfied they are with the program. He will also be talking with neighbors.

Preliminary research indicates landowners participate for a variety of reasons, including a belief in conservation, a way to enhance the natural beauty of the land and an increase in hunting and fishing opportunities.

鈥淔rom several standpoints, it鈥檚 just good to know why people do things in regards to conservation鈥攚hat motivates them,鈥� says Welsh, who came to SU in 2012 from Clarkson. 鈥淎nd secondly, these programs could tailor their recruitment strategies and marketing toward those motivations. The more you understand why people do things the more it enables you to better manage the relationship and be a more effective communicator.鈥�

In preliminary research, Welsh has found that people participate for a variety of reasons, including a belief in conservation, a way to enhance the natural beauty of the land and an increase in hunting and fishing opportunities. 鈥淭hey tend to downplay the monetary aspects and are more interested in the social and personal benefits,鈥� he says.

For Welsh and Chandler, who have been friends since they attended Cornell University, the interdisciplinary nature of the work is rewarding to the field and to their own knowledge.

鈥淲e are strongly invested in learning what is important in other people鈥檚 research and how that can contribute to ours鈥攁nd how ours can contribute to their research,鈥� Chandler says.
