Conservation Stirs Controversy in Avon Hills



            Gary Pflueger had no time to talk- he was too busy, juggling his responsibilities working on the grounds at Saint John’s University and running his small farm in the rocky slopes and wet valleys that lie between Avon and Saint Joseph, Minnesota. When I caught up with him, to ask his opinion on the local Avon Hills Initiative, he paused only for a few seconds.

“Well”, said, “I got to tell you, they’re certainly not my favorite organization”

            A strong opinion, by Central Minnesota standards. It was the first, though not the last, of many uncharacteristically strong opinions I would hear that day. But what was it that could invoke such feelings of passion from a stoic resident of ‘Lake Wobegon’ country? It is a story of changes in a community, and of the relationship between residents, a university, and local government. 
           
As with so many things in rural America, though, it all starts with the land.

            The Avon Hills rise above the farms of eastern Stearns County, 80 square miles of rolling slopes, eskers, and moraines dotted with lakes and marshes, carved by the retreating glaciers of the last ice age. What sets the region apart from the surrounding fields, however, is the forest. The hills, which stretch over the Avon, Collegeville, Saint Joseph, and Saint Wendel townships, contain the highest concentration of the native plant communities in the county, with abundant oak, maple, and basswood forest, tamarack and mixed-hardwood swamps, and wetland meadows.
The Hills contain the largest intact forest in central Minnesota
            These forests were once common throughout central Minnesota, but largely disappeared with the arrival of white settlement, giving way to farm fields. The Avon Hills were preserved by their topography. The rolling slopes, soil thick with stones, and marshes were not hospitable to large expanses of corn. A handful of families carved out small patches of farmland and grazed livestock, but outside of the town of Avon itself and the grounds of Saint John’s Abbey and University, the hills were largely spared the axe and the plow, leaving the forest intact.
            That forest supports a diversity of animal life. In addition to the deer, coyotes, beavers, and other common animals, the region harbors several rare species, including the cerulean warbler, red-shouldered hawk, least darter, Blanding's turtle, and American ginseng. It has been categorized as ecologically significant by both the Minnesota DNR and the Nature Conservancy's Eco-Regional Plan. The Hills, the largest intact block of kettle and moraine forest between the Twin Cities and Morrison County, are also a rest stop for migrating bird populations through Minnesota and habitat for wood ducks and other water fowl as well as songbirds, for which it is recognized as an Important Bird Area by the Minnesota DNR.
 Family farms have declined in recent decades
            Some residents, however, worry that the Hills are at risk. The forest has come under increasing pressure from development in the last four decades. The north end of the hills were intersected by I-94 in the 1970s, at the same time that an emerging middle class drove demand for scenic lakeshore and rural land. The demographics of the community have shifted from the large, long-standing holdings of family farms towards the newer, smaller plots that host the homes of professionals and small business owners.

            “Collegeville does not support a lot of full time farmers anymore.”, said one resident of the township who preferred not to be named “We’ve become a recreational area, with the lakes. There’s a lot of development pressure, and the ecosystem is pretty fragile.”

            The development pressure does not come only from the demand for scenic property. The nearby urban area is expanding- in the 2000s, Saint Joseph was the second fastest growing city in Minnesota, beaten only by nearby Sartell. The population of Stearns County is expected to increase up to 33% between 2000 and 2030, according to the Stearns County Comprehensive Plan. With such growth, conservation advocates worry that the Hills may see housing developments replace woodland.
                       
Many Minnesotans aspire to own a home by a lake
            It was in the midst of these concerns that the Avon Hills Initiative formed in 2003. The group, which consists of local residents as well as members of the Saint John’s University community, states that it aims to “Preserve the rural character of our community, protect the quality of our natural areas, and maintain economic productivity in our communities while respecting individual landowner rights”.
            To this end, the Initiative has sought to establish a series of six to ten conservation easements throughout the Avon Hills. These easements, funded in part by a grant from the Minnesota Environment and Natural Resources Trust Fund, allow landowners to retain ownership of the land, but restricts development of the land or use that is not consistent with the protection of the natural features as specified in the easement. The easement remains even if ownership of the land transfers. The first of these easements was completed in 2009, on 34 acres along Watab Creek belonging to Robert and Bonnie Thomsen.
            Kate Bobeldyk, the Chair of the Executive Committee of the Initiative, says that the organization is now in the second round of seeking easements to both preserve and restore local land.

            “Most people love the hills, water, wildlife, and open spaces and want to preserve it.” said Bobeldyk “Sometimes, they don't know how, so our goal is to help them to do it- to offer them guidelines and incentives. We're not in the business of trying to regulate or police what's going on our here. We’re in the business of trying to educate, and pull together the right people, whether it be the county or the township.”

            The Initiative has helped Stearns County and local townships to design a Conservation Overlay district for the Avon Hills, Bobeldyk said. This special district, which overlaps the four townships on which the hills rest, limits the number of building sites per acreage, requiring a certain amount of land to remain undeveloped. It also allows cluster development, which allows several houses to be built in close proximity if nearby land is set off as open space.

            “I'm not sure if I agree with all of the zoning ideas- like cluster housing.” said Ben Carlson, an SJU senior and local resident. “I think the AHI should focus more on the agricultural aspect and on the value of woodlands.”

Wetlands at the Saint John's Arboretum
            Stearns County was awarded the 2010 County Conservation Award for its establishment of the overlay district.
            The Initiative also organizes the Avon Hills Conference, a day-long collection of seminars and discussions held annually at Saint John’s University, exploring topics that range from nature photography to green construction. John O’Reilly is an organizer of the event, which will next be held on February 2, 2013.

            “The executive committee initially started the Avon Hills Conference as a way for local landowners to learn more about conservation and easements”, said O’Reilly, “But it quickly evolved into an event for all Avon Hills residents to have a day of learning and community.”

Ben Carlson praised the conference.

            “I think it’s a great chance for Saint John’s to interact with the community.”, he said. “There are the old farmers, and the other people who live here because of the lakes or the university, and it’s a great chance for the monastic community to connect with both groups”

            Some who support the Initiative, however, express certain concerns. One local who chose to remain anonymous worries about the effect of conservation in the Hills on surrounding farming communities.

            “I think they can go against the grain of farming issues, because they want to put the development out of woodland areas and into prime farming areas”, he said.

            He clarified, however, that he views the Initiative as a ‘valuable voice in the community’.

            Other residents are more critical of the project. Among them is local landowner Dan Vogel, who harbors concerns over the role that Saint John’s University plays in the program. Vogel sees the program as being initiated by the University, not the surrounding community. He notes the involvement of Abbey and University members in the initiative, such non-voting spots on the board held by employees of Saint John’s, and the hosting of Initiative-related events on the campus, as evidence of the University’s role- a role that he describes as hypocritical given the University’s own development.

Saint John's University, in the north of the Hills
            “Since the Avon Hills Initiative has started, Saint John's has doubled their cemetery, built a guest house, the McKeown Center, the large Flynntown apartments, and four or five acres to build the solar panels, and have plans now for expanding the library, doubled the size of the buildings by the sugar shack.”, said Vogel. “Saint John's is the biggest developer in the area.”

            Vogel added that he does not oppose conservation, but rather what he sees as conflicts of interest on the part of Saint John’s involvement in the Initiative.

            "I'm totally for conserving property, but what I have problem with is the biggest developer in the area starting this initiative to stop or regulate development in the surrounding area. When the largest industry in the area uses their money to push a program and to change the rules behind everyone's back, and they don't fall underneath it, I don't think that's fair"

            Area resident Shelly Carlson, however, welcomes the University’s involvement. “Saint John’s was here before any of us.”, she said “They’ve always been kind of a rock. The community grew around Saint John’s, so for them to reach out like that is just a natural thing”

            Kate Bobeldyk asserts that most of the local community stands behind the Initiative. “They want to preserve the rural land and use it for recreation.”, she said “They want to look at it and be proud of it.”

            Vogel, Pflueger, and others like them, though, are not yet convinced of the Initative’s good intentions.
  
            “I think there's little to no support from the local area.”, said Vogel. “I'm quite sure all my neighbors are not in favor.”

Quick Hits: Fire Approaches Blowdown Area, Anoka Wildlife Corridor, Pesticides v Zebra Mussels

Fire Approaches Blowdown Area
The Superior National Forest has expanded a closure area, as the Wooden Leg Fire moves towards the high-risk 1999 blowdown area. The Wooden Leg Fire, which is only a quarter acre in size, has already sparked the closing of Ensign Lake some twenty miles from Ely. The closure has been epanded to several other lakes, in response to the fire's progression towards a tract of land that contains a great amount of highly flammable dead wood, the result of a wind storm over a decade ago.

Anoka Wildlife Corridor
John and Barb Anderson, fourth-generation Anoka landowners, have joined with the Minnesota Land Trust to protect valuable wildlife habitat in the urbanized county. The 80 acres of grasses and wetland provide key habitat for species identified by Minnesota's Comprehensive Wildlife Conservation Strategy, including the red-headed woodpecker, smooth green snake, and Nelson's sharp-tailed sparrow. Along with the 92 acre easement made by the family in 2005, over half of the 260 acre farm is preserved for wildlife. Funding for the project was provided by the Minnesota Environment and Natural Resources Trust Fund through their Metro Conservation Corridors program, which seeks to connect the disaparate patches of high-quality habitat throughout the metro, creating more resilient wildlife communities.

Pesticides v Zebra Mussels
The experimental use of pesticides to control zebra mussels may be working in one northern Minnesota lake, according to the DNR. The agency applied the treatment to Rose Lake in Otter Tail County last autumn when a small population of the invasive species was found in the lake. No zebra mussels have been found in the water samples from Rose Lake this summer, says DNR Invasive Species Specialist Nathan Olson. He urges caution, however. "From my experience with zebra mussels, they seem to have a really big increase in about two years,once they're found in a lake," Olson said. "If I don't see any zebra mussels for about two years, then I'm going to be more excited about our success rate."

A New Weapon In the War on Zebra Mussels

Zebra mussels may soon learn the name of fear- and that name is zequanox.

Zequanox is a bacteria, bred from the Pseudomonas fluorescens species, which can be found naturally protecting certain plants from breeds of parasitic fungi and nematodes. It has been selected by a team from the New York State Museum which has spent two decades researching a potential bacterial remedy to the zebra mussel invasion- a plague that has already infested over fifty of our state's lakes. The mussels, introduced through the Great Lakes in the 1980s, displace native species, cling to boats and docks, and even clog pipes, and as yet remain difficult to stop. A trial run being carried out on mussels at Lake Carlos with the help of the Minnesta DNR and US Geological Survey may change that, however.




The bacteria is not being introduced into the lake itself- instead, the mussels are being gathered and bathed in water that contains the bacteria for twelve hours, to measure their effectiveness against the mussels. In the words of USGS fisheries biologist Jim Luoma "What we're trying to do with this trailer is to mimic a treatment like it would be in a lake without actually applying the product to the lake." Previous tests have seen casualty rates of over 90%, with most deaths occurring within ten days of treatment.


Zebra mussels can clog pipes and engines


Denise Mayer, one of the researchers on the project, stresses that zequanox is not likely to be used on whole lakes- rather, the likely approach "is to use it as a tool to prevent infestations very early on if you find a localized infestation around a boat launch or marina or a dock,"and in this way prevent the further infestation of the lake.

Lake Peppin and Wisconsin's Lake Shawano will also be test sites, after the Lake Carlos trial is complete.
