New and old users of Tipping Point Planner collaborate at Purdue workshop

Researchers, federal and state government and non-government officials, students, and representatives from Ohio, Wisconsin, and Michigan Sea Grants gathered at Purdue University recently to take part in the two-day Tipping Point Planner collaboration workshop.

The web tool uses the latest watershed research and cutting-edge technology to show planners how close their watershed is to known environmental tipping points and what the watershed will look like if land use decisions continue “business as usual.”

Planners can also test how developing more in one location or restoring habitats in another moves ecosystems closer to or further from tipping points. With help from a Sea Grant facilitator, planners can use these interactive maps and simulators—along with recommended policies, ordinances, and outreach efforts—to prevent aquatic ecosystems from being degraded beyond repair.

The program’s name is shorter and the homepage has a new look, but the goals for this powerful watershed-planning tool are the same. Some of those in attendance were part of the original team that helped get the program off the ground in 2010 and others were using it for the first time.

The purpose of this workshop was to gather researchers and end-users of this decision-support system as well as partner government agencies to take part in feedback sessions to help inform the development of the upcoming redesign of the Tipping Point Planner website.

Kara Salazar, IISG sustainable communities outreach specialist, has helped communities since 2012 learn how to use Tipping Point Planner in their area.  Now Salazar, along with Dan Walker, community planning specialist and Lydia Utley, data analyst, are continuing to expand the tool’s use and functionality.

“Communities plan for many reasons. The Tipping Point Planner process can support a community’s vision for managing land use while minimizing impacts on water quality,” Salazar said.

The first day of the workshop featured talks from researchers from the Great Lakes region followed by breakout sessions led by Purdue researchers on emerging issues. The second day addressed nutrients and food webs, new topics to the Tipping Point Planner tool.

Larry Theller of Purdue gives a talk on “L-THIA works inside Tipping Point Planner.” L-THIA was developed as a straightforward analysis tool to provide estimates of changes in runoff, recharge, and nonpoint source pollution resulting from past or proposed land use changes.

Chelsea Cottingham, watershed specialist at the Indiana Department of Environmental Management sees Tipping Point Planner as a tool for groups she works with that are in the early stages of the land-use planning process. The watershed she manages in northwest Indiana includes agriculture and urban land.

“In large watersheds there are various types of land uses and some of those uses have competing interest in terms of social priorities for the groups of people that live there, as a result we’ve got competing interests,” Cottingham said. “We’re trying to put management practices on the ground to help reduce our nonpoint source pollution and our impact.”

Joe Lucente, Ohio Sea Grant, extension educator, community development, has been involved with Tipping Point Planner from the beginning. Much of his work with communities focuses on economic development and sees how Tipping Point Planner can help.

“We’re trying to gather and see where we’re at in the development of this program and then see how it fits in to the particular community, how we can integrate (Tipping Point Planner) into their comprehensive planning process,” Lucente said. “We’re trying not to take a one-size-fits-all approach, we’re trying to see what makes sense, to see the benefits of it and hopefully start to really put it to use.”

To address that need for more specialized land-use needs, developers of the tool are working to make its calculations more exact to an area.

Edward Rutherford, a fishery biologist at NOAA in Michigan, asks a question during the researcher presentation portion of the workshop.

“It’s still at a watershed basis. We’re making it more goal specific so when a community begins the planning process for a specific topic or goal, we’ll be able to more effectively streamline them through the process,” Salazar said.

“Going forward, we’ll have data maps and information that are tailored to that specific area.”

Tipping Point Planner was developed in collaboration with Purdue University, University of Michigan, Michigan State University, University of Minnesota Duluth, University of Windsor, the Great Lakes Environmental Research Laboratory, the Cooperative Institute for Limnology and Ecosystem Research, the Great Lakes Restoration Initiative, NOAA, and the Great Lakes Sea Grant Network. Funding for the four-year project comes from NOAA and EPA.

Illinois-Indiana Sea Grant is a part of University of Illinois Extension and Purdue University Extension.
