Thriving beavers bother area landowners
Bill Hosford/KANSAN
By DAVID SWAFFORD Staff Reporter
Beavers are thriving in Douglas County, as indicated by these felled trees next to a small creek near West 31st Street. The beavers are causing problems for some Douglas County landowners.
Beavers are thriving in Douglas County streams and rivers, and their proliferation is causing problems for county landowners.
"There are lots of them around here and now they have started to deprecate some people's property."
PHIL. MOORE, Douglas County field and stream agent, said one of the reasons the beaver had been so successful it did not have any natural predators.
Many beavers also have colonized in streams that feed into the Kaw River, he said.
Burtwell said Douglas County had the right kind of food and habitat to support beavers. The Kaw River, he said, is a natural reservoir for beavers, one they were taking advantage of.
Bruce Snodgrass, 1206 W. 31st St,
said beavers had grown down some ash trees east of his house. "I'd say we've taken down a couple dozen on them."
"They cropped up last year and damned up the drainage ditch out to the side of the house pretty well. The biggest damage they could do would be to cause the drainage water to shift course, start washing away my brome field."
BURTWELL SAID that if an individual had enough problems with beavers, he could get a permit from the state to shoot them.
But Snodgrass said, "I don't want to do that. I hate to do anything to that."
Burtwell said the low price of beaver pelts had contributed to the population problem. He said that beavers could only be trapped, not shot. The low price that short-hair pelts, such as beaver, are bringing about an increase in time and bounce it takes to trap them has led to less trapping, he said.
"To trap beavers, one may have to chop through ice and then set up a trap in extremely cold water. A lot of landowners think the time spent on setting up traps is just not worth the money." Burtwell said.
CLARENCE WALES, owner of
Wales Enterprise, 923 Delaware St.,
which buys furs and pelts, said that
fully dressed dressed pelts were

price, wailing $18 a piece.
welling $18 a piece.
Both prices are down from recent years, he said.
Another spot where beavers have caused problems in Douglas County is a 15-acre plot of land near the lake, on the north side of the line, north of the Lawrence airport.
One of the owners of the land, Ann Sanders, said the beavers had been on her land for about six years. She thought the beavers came onto her land about six years ago because the U.S. Army Corps of Engineers had
"When they tried to straighten out the banks," Sanders said, "they destroyed the beavers' homes. Nature had had to move, so they came here."
attempted to straighten the banks of nearby Mud Creek.
SANDERS' HOME is on a ridge above a pond. She said the beavers had done the most damage around the pond, where they had cut down at least 4 acres of willow and cottonwood trees.
She said that the beavers were now gnawing away at the hickory trees on the opposite ridge.
Sanders said that she and the other landowners of the 15-acre plot have tried several ways to stop the storm, but that none had worked so far.
"First we tried building barbed wire fences around each tree that we thought they would eat, but they either went around or under those," she said. "Then we tried spreading cowate manure around those trees, thinking the beavers would not come near the cowate scent.
"SOME OF THE owners stayed up at night, went down in the woods, and actually yelled at them, hoping that they would leave. We've tried spreading a solution of dehydrated rotten eggs on the trees we thought they were going to eat, in hopes that strong odor would drive them away.
The beavers, Sanders said, are only doing what comes naturally to them—surviving.
"They're too wise to traps."
KU clinic to test effects of drugs on cholesterol
By MICHAEL BECK Staff Reporter
The University of Kansas Medical Center will pay $35 to anyone who refers a person with high blood pressure to the research project at the Med Center.
Susan DeCoursey, a co-director of the Lipid and Arteriosclerosis Prevention Clinic, said this week that the clinic would soon test two anti-hypertension drugs to see how they change cholesterol levels.
Researchers are screening patients for mild to moderate hypertension, she said, but the actual testing of the drugs will begin in about two weeks.
BESIDES THE $35, which the person must spend at the bookstore at the Meed Center, the patients will get free medication, tests and check-ups.
The project will involve Inderal, a commercially produced drug that is thought to affect cholesterol levels in patients with hypertension, and bucundulol, which has not been approved for commercial production and is not thought to affect cholesterol level, she said.
But doctors do not know the exact effects of the beta blockers on cholesterol level, she said. With the project, researchers hope to find out.
High blood pressure causes the artery walls to contract and grow stiff, and both of the drugs, called beta blockers, are used to relax the artery walls.
BETA BLOCKERS can cause complications in treatment of hypertension
More cholesterol in the blood can increase the risk of heart attacks because cholesterol often attaches to arteries. Less than 10% of clots that can disrupt the flow of blood
He said that researchers have connected hypertension with arterial disease.
Much of the research in hypertension has dealt with preventing the disease because doctors thought that those with hypertension would contract arteriosclerosis, said Bruce Johnson, associate director for the College of Health Sciences.
However, treatments for arteriosclerosis differ from treatments for hypertension in that doctors concentrate more on the function of the vessel wall than the volume of blood retained in the body, thus the muscles of the artery walls.
OF THE DIFFERENT kinds of heart disease, which is the leading killer in the United States and Europe, hypertension represents about 25 percent of all cases.
A person with hypertension will have a systolic, or pressure at which the heart pumps the blood into the arteries, reading of 150 or above and a diastolic, or constant blood pressure, reading of 90 or above.
A normal blood pressure reading is about 120 over 80.
Hypertension also can cause the heart to enlarge and overwork, and it increases blood pressure.
