Fermilab prairie helps engineers protect wetlands

Environmental experts examine Fermilab's prairie to learn about rare plants.

Robert Mohlenbrock glanced to his right and spied a thin green stalk amidst a sea of grasses and flowers.

“Oooohhh. Look at this guy,” he said to the nearly two dozen federal environmental engineers eagerly jotting down his every word. “There’s a stem without a leaf on it. That has got to be Eleocharis. This used to be the hardest thing to identify; now it’s the easiest.”

As knowledge about native wetland plants and grasses expands and suburban sprawl shrinks their numbers, having an eye for what needs conserving has become a much sought-after skill.

Mohlenbrock, a Southern Illinois University Carbondale professor emeritus and renowned author, uses Fermilab as his training ground because of its unique floral diversity. The site boasts 1,100 acres of restored tallgrass prairie, of which less than one-tenth of 1 percent remains in Illinois.

“A site like this is going to have a higher quality,” said Keith Wozniak, chief of the west division of the Chicago District Army Corps of Engineers.

The Corps, along with DuPage County, send wetland regulators to places like Fermilab twice a year to learn how to spot the rarest flora on sites eyed for development. This training increases the likelihood of spotting even a few rare plants so that officials can work with developers to build around the wetlands or, at a minimum, ensure adequate replacement of the wetland through the Illinois wetland banking system. Developers purchase credits to replace wetland damage by creating, restoring, enhancing or preserving wetlands in other locations. In 1991, the federal government adopted the Illinois model as a national standard.

Anything larger than one-tenth an acre requires remediation. Just how much, depends on the quality of the wetland, a designation reached through a formula weighing the amount, variety and rarity of wetland flora.

Fermilab’s large number of wetland species, including several rare varieties, gives environmental engineers a chance to learn about flora they might otherwise overlook. When asked why the U.S. Army Corps of Engineers chooses Fermilab as a classroom, several members immediately remarked on the high quality and diversity of the plantlife. Many of the other training sites the engineers see have less than half a dozen species of wetland plants and grasses, Wozniak said.

The high-quality prairie and wetland species thrive through a program of invasive plant removal, restoration efforts and Fermilab’s commitment to stewardship.

Fermilab hosts a searchable plant database and actively recruits volunteers for restoration activities.

Northland teacher selected for physics project

From Northland Press, Sept. 28, 2010

Jackie Kitchenhoff, Northland Community Schools Science Teacher, was one of two Minnesota teachers selected this past summer to participate in an Education and Public Outreach Program sponsored in part by the National Science Foundation and the Department of Energy.

The program's goals were to produce two unit plans for a highschool classroom activity using data collected from the MINERvA detector located at Fermilab located just outside of Chicago, Illinois. The lessons challenge students to improve their abstract thinking and inspire a curiosity of subatomic particles and the field of Particle Physics.

Bed bugs: the out-of-sight bite in the night

High-energy particle physics experiments occur across the United States and across the globe. The international nature of the field means that experimenters travel often for research or conferences. Jetlag used to be the main headache from frequent travel, but now travelers also have to worry about bed bugs.

Complaints about the pests have risen since 1995.

It is thought that years of DDT pesticide application was the main reason for the near disappearance of bedbugs around the 1950s. Subsequent to the ecologically appropriate ban on DDT, the numbers of bedbugs rose.

An adult bed bug is about 5 mm long and 3 mm wide and brown. A rather flat profile aids its concealment. They tend to shun light, so an inspection for the bug itself has to be well coordinated. Telltale signs of infestation are brown feces stains resembling dried blood on bedding or mattress and bites occurring in a group of three, usually in a line. Bedbug infestations do not equate to bad housekeeping. These little critters hitchhike to their new homes in luggage, on clothing or on used furniture. Because of this, quarantining luggage in a garage or bathtub upon a return from travel was once a common practice.

Bedbugs crawl but cannot fly.

The good news is that as despicable as these blood suckers are, they do not transmit diseases. Tests with AIDS and Hepatitis B viruses found the bed bugs did not pass along through blood transfer sufficient amounts of the viruses to cause diseases and were incapable of reproducing the virus themselves.

The worst you can expect to get from these insects’ bites is a possible allergic reaction to the bite or contact with the molted shell.

For more information on bed bugs visit the Centers for Disease Control and the National Pest Management Association.
