MN DNR conservation officers using dogs to detect zebra mussels
Really creative way to tackle the problem of Zebra Mussels in Minnesota. The story comes to us via the Minnesota DNR
--------------------------------------------------------------------------
DNR NEWS - FOR IMMEDIATE RELEASE May 7, 2013
DNR conservation officers using dogs to detect zebra mussels
The Minnesota Department of Natural Resources (DNR) will be using three zebra mussel-sniffing K-9 teams for the first time this year to help combat the spread of aquatic invasive species (AIS).
Minnesota is the second state in the country to use trained dogs to prevent the spread of AIS. They will be used throughout the state during the open water season.
“The use of K-9s is a progressive enforcement tool that will complement and support our invasive species prevention efforts,” said Col. Jim Konrad, DNR Enforcement director. “However, they should not overshadow the fact that preventing the spread of AIS is still everyone’s personal responsibility.”
Earlier this year, conservation officers Todd Kanieski and Travis Muyres traveled to California to learn about the country’s first program successfully utilizing mussel trained K-9’s to prevent the spread of AIS.
“A K-9 can find a mussel on a boat much faster than a human inspector,” said Kanieski.
The Minnesota mussel dogs were trained in-house for five weeks by Muyres, an experienced
K-9 handler and certified K-9 unit trainer.
Muyres’ K-9 mussel team partner “Laina” is a Belgium Malinois purchased from a domestic breeder. The other teams include water resource enforcement officers Lt. Julie Siems and her K-9 partner “Brady” and Lt. Larry Hanson and his K-9 partner “Digger.” Siems’ and Hanson’s dogs are Labrador retrievers provided by animal shelters and animal rescue organizations.
“It’s very difficult to find a qualified prospective detector dog, but each of the dogs selected from the shelter was healthy, sociable and had a strong search drive,” said Muyres. “That search drive will prove to be invaluable in detecting AIS.”
The mussel detecting K-9s will also be trained in tracking, evidence recovery, firearms detection, and wildlife detection.
“Combining mussel detecting with these additional skills will add muscle to the DNR’s capabilities and efficiency in protecting the state’s natural resources,” said Kanieski.
The DNR Enforcement Division has utilized K-9s to assist in protecting our natural resources since 1995. The DNR’s two current K-9 units are not trained in mussel detection.
According to the DNR, zebra mussels can multiply out of control and dramatically change the ecosystem of a body of water. They are often transported from lake to lake by boaters. The mussels are only about the size of a finger nail, and their larvae microscopic, making them tough to find. They have been discovered on various lakes across the state.
The DNR will also have between 126 and 146 human watercraft inspectors stationed around the state at various lakes this summer.
Boaters and anglers need to continue to take extra precautions when using Minnesota waters to avoid spreading AIS to new waters.
Boaters are required by law to:

--------------------------------------------------------------------------
DNR NEWS - FOR IMMEDIATE RELEASE May 7, 2013
- Remove aquatic plants, zebra mussels and other prohibited species from boats, trailers and equipment before transporting from any water access.
- Drain all water from bilges, livewells, motors, ballast tanks and portable bait containers before leaving water accesses or shoreline property.
- Remove the drain plug, open water draining devices, and drain bilges and livewells; the drain plug must be removed or open when transporting a boat on public roads.

Mendota man battles non-native plants
By Jeff Dankert
To restore and maintain native plants, Bryon Walters wages war.
The 53-year-old conservation biologist from Mendota cuts down invasive non-native plants and when that doesn’t work, he turns to chemical warfare.
Walters fights on many fronts through his one-man company, Illinois Natural Areas Improvements.
Most recently Starved Rock State Park called Walters to attack a grove of black locust trees and other non-native plants at the park’s west entrance.
“That just helps out whenever you get rid of the negative component, the natives have a better chance of prospering and flourishing,” Walters said. “You need to tend to it like a garden. You can’t just let it sit idle.”
Walters, with assistance of state forester Randy Timmons, arborist Scott Shearer and a tree crew, cut down the locusts. This tree is native to the southeastern U.S. and far southern Illinois but has been widely transplanted beyond its native range. Walters treated the cut stumps with glyphosphate to prevent re-sprouting.
If the locust was the only problem, Walters’ job would be easier.
“We cleared the black locust but there’s a plethora of exotics underneath,” Walters said.
This week he returned with a backpack sprayer filled with 2,4-D and tricoplyr to drive back other aggressive invaders. He moved across the slope and jetted a blue spray on bull thistle, cutleaf teasel, poison hemlock, burdock and others. He also identified non-native reed canary grass, common buckthorn, catnip, garlic mustard and Asian honeysuckle.
The teasel from Europe has spread along roadsides through regular mowing, which disperses seeds, Walters said. It creates “a trail of teasel,” he said.
Herbicides are a last resort on natural areas. But when mechanical means like pulling or cutting don’t work, you have to use chemicals or you lose the battle, Walters said.
Park superintendent Mark McConnaughhay said he turns to Walters for burning prairies to spraying patches of aggressive and out-of-place plants, with guidance of Illinois Department of Natural Resources district heritage biologist Dan Kirk. A state Natural Area Acquisition Fund helps pay for Walters’ services.
Walters began his natural resources career as a bird biologist but realized bird surveys were not going to pay the bills. A professional acquaintance nudged him toward vegetation management. That was 25 years ago. Walters has been busy.
“It’s a job that’s always going to be there,” Walters said.
He began his new career with classes at Morton Arboretum and volunteering with The Nature Conservancy, he said. His job requires broad knowledge of botany and plant ecology and skills using field equipment. He must remain licensed and certified as a pesticide applicator.
The public has misperceptions about his work, about plants and about their interactions on the landscape, Walters said.
“They assume these areas take care of themselves and they don’t,” he said. “Careful thought needs to be put into how you plant and how you landscape to preserve our natural biodiversity.”
The North American landscape once took care of itself. After Europeans invaded, the landscape was patch-worked into crop fields. Agriculture, industry, transportation and technology rapidly altered the land. Intentional plantings and accidental introductions began replacing native plants. It wiped out 99 percent of the natural areas of Illinois, Walters said.
“No other state is more altered than Illinois,” he said. “Our ecosystem can’t take this constant barrage.”
Illinois’ economic drivers of agriculture and industry mostly trump care for flora and fauna, Walters said.
This makes something like Starved Rock State Park “an oasis in an agricultural and industrial area,” he said.
Native landscapes could have played an economic role in the most obvious, recent example of record floods.
Native grasslands and wetlands filter and soak up water. If they were restored on a scale that mattered, this could have saved the state and its citizens billions of dollars, Walters said.
For the first time in years, the south slope along the park entrance provides a locust-free view of the limestone cliffs and native plants like witch hazel, red-berried elderberry, pagoda dogwood, white pines, Solomon’s seal, bloodroot, Dutchman’s breeches, yellow bellwort, Canada anemone and others.
The west entrance once hugged the bluff. It was later elevated and the sloping shoulder was planted with black locusts, considered a good choice for soil erosion. It was a bad choice. It is not native; it shades out spring wildflowers; and it is allotropic, giving off chemicals that prevent competition from other plants. Asian honeysuckle also is allotropic, Walters said.
“Honeysuckle, it’s the No. 1 plant we need to go after statewide,” he said.
There are native honeysuckles but these are seldom grown and sold, he said.
The site will require many visits to eradicate invasive plants. Walters will revisit the locust patch in two to three weeks. The site has a good base of natives, growing and with seed in the soil, so Walters won’t have to plant any natives, he said.
This fall, he will use a controlled burn to further knock back invasive plants, reduce some of the locust timber and encourage more natives.
“Because we fragment the land, it’s an ongoing process,” Walters said. “It’s a long road for that recovery.”

Article - Land invasion: Bradford Pear Tree
A nice article on the invasion of Bradford Pear in Illinois from Chris Young of the Peoria Journal Star.
See original article HERE.
Land Invasion: Bradford Pear Tree
by Chris Young, Peoria Journal Star
--
It’s a stealthy invader cloaked in beautiful white flowers.
Bradford pear trees have been popular landscape trees, being planted extensively since the late 1980s and 1990s.
Originally, the varieties sold were grown from cuttings that were supposed to produce trees that were sterile.
They were genetically similar enough they couldn’t pollinate each other.
But those first trees were prone to splitting in high winds, so new varieties were developed to combat that problem.
The unintended consequence of fixing one problem was to create another.
The new varieties were able to pollinate the original trees that were still around.
“They started introducing new selections, and once those trees were planted, they were able to cross-pollinate the Bradfords that were already out there,” said Alana McKean, manager of Starhill Forest Arboretum outside Petersburg.
The fruits are small, nothing like pears found in the supermarket.
“Not only do the fruits drop right there under the trees, but the birds pick them up and carry them for miles.”
The result was Bradford pear trees showing up along roadsides, in woodlands and just about everywhere else.
Petersburg arborist and author Guy Sternberg, who owns Starhill Forest Arboretum with his wife, Edie, said invasive species often start out harmless.
“But invasive species tend to sleep, creep and then leap,” he said, referring to a confluence of events that allow a plant to break out and “leap” past the competition.
Many people likely mistake Bradford pears for flowering dogwoods in the spring.
In the fall, the deep burgundy leaves stay around long after other trees have gone bare.
“It was a plant that behaved for many years until these other varieties came along that started producing viable seed, and then it took off,” said Chris Evans, Illinois Department of Natural Resources invasive species program manager.
