The New Wildlife Refuge: Golf Courses?

12.07.2007
MU researchers find that golf courses could be wildlife sanctuaries, but change is needed in pond management

Golf courses are known as centers for human recreation, but if managed properly, they also could be important wildlife sanctuaries, a University of Missouri-Columbia researcher has found.

"There are more than 17,000 golf courses in the United States, and approximately 70 percent of that land is not used for playing," said Ray Semlitsch, Curators' Professor of Biology in the MU College of Arts and Science. "These managed green spaces aren't surrogates for protected land and ecosystems, but they can include suitable habitat for species native to the area. Golf courses could act as nature sanctuaries if managed properly."

Semlitsch, along with Michelle Boone, an assistant professor at Miami University in Ohio and former MU graduate student, and J. Russell Bodie, senior scientist for Audubon International, outlined recommendations that would improve golf course habitats for amphibian populations in a paper published in USGA Turfgrass and Environmental Research Online in January. Their recommendations included buffering aquatic habitats from chemical runoff, surrounding wetland areas with 150 to 300 meters of forest or natural grassland, and creating a diversity of pond types that mimic natural wetlands.

A recent study by Semlitsch, Boone and Cory Mosby, a senior at MU, built on these suggestions. They found that completely drying golf course ponds in the late summer or early fall would benefit amphibian populations and biodiversity.

"It's a hard concept for people to understand, but non-permanent wetlands are more natural than permanent wetlands. Most natural wetlands dry for some periods of time, and the species that live in them are well-adapted for this. The natural drying process benefits amphibians, and it releases nutrients from the soil. Maintaining permanent ponds actually harms biodiversity," Semlitsch said.

In the study, the researchers used two types of ponds - control reference ponds and ponds located on golf courses - to monitor populations of American toads, southern leopard frogs and spotted salamanders. They found that the American toads, southern leopard frogs and spotted salamanders survived better in the golf course ponds than in the control ponds, probably because of a reduced number of insect predators. They also found that these species survived better in the absence of overwintered bullfrog tadpoles, which are common to permanent golf course ponds and act as unnatural predators and competitors.

Semlitsch said this shows that greater biodiversity can be achieved by eliminating bullfrog tadpoles. Because bullfrog cycles of metamorphosis take longer to complete (typically 12 months) than the cycles of other amphibians (typically one to four months), the bullfrog tadpoles have advantages in permanent ponds and can grow larger and more powerful, nudging out other species. By drying golf course ponds in the early fall, the tadpoles can be eliminated,

Semlitsch, Boone and Mosby's study will be published later this year in the journal Conservation Biology. It was supported by the United States Golf Association and the National Fish and Wildlife Foundation.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
