Heritage LandKeepers

This page is dedicated to our Heritage LandKeepers, landowners who have made a commitment to protecting their land in perpetuity by putting a conservation easement on their property. Read their stories here about what inspires them to protect the conservation values of their land - the natural and scenic features - for their future generations. We hope you are as inspired as we are with their vision for the future.

Stories of Our Heritage LandKeepers

Robert and Vicki Stretton

Over a hundred years ago, a young couple, John and Christina Handel, homesteaded a beautiful and extraordinary property just north of the town of Savanna, Illinois. They chose a site to raise their family that had everything from steep sloping forests and dramatic cliffs to grassland for their fields, as well as wetland areas.

Vicki Stretton inherited a portion of the property from her father that her grandparents had homesteaded long ago. When Kerry Leigh, NLI Executive Director, visited with Vicki and her husband Robert in the fall of 2013, she showed Kerry the part of the house that was the original log cabin built by Vicki's grandparents, with the still-sloping floor. She told Kerry stories about her and her brother, Bill Handel, playing with marbles on that floor when they were children and how those marbles would roll down the floor, and jump the boards. She also told Kerry stories of the land, and how as children they loved to roam the woods and search out wildflowers.

When Kerry visited during the fall to work on finalizing the conservation easement, she told them she wanted to get some fall color photos of their forest before she left, so Robert fetched her a walking stick made by Vicki’s dad. It was a wet, drizzly autumn day and as she walked along the edge of the woods, Kerry said, "it saved me many times on that steeply sloping land. I was grateful for the stick, and as the foggy wet air infused a magical quality into the woods I felt profoundly honored, as Vicki and Robert are, to be treading in the footsteps of their ancestors on this well-loved and cared for property."

The largest part of the land is upland oak-hickory forest that nurtures rare and unique plants. Vicki’s love of this wild land was the driving force for her to protect it. She and Robert want to preserve this part of the old homestead not only for their family but for the wildlife and the rare plants found there. Vicki’s brother, Bill Handel, is a botanist for the Illinois Natural History Survey and has been actively helping them manage the property with controlled burns and wildlife management. Vicki and Robert chose NLI to protect their property through a conservation easement, as they had seen NLI protect other properties close by. They feel that NLI’s goals and purposes are similar to theirs. In November of 2013, the easement with the Strettons was finalized to protect, in perpetuity, 35 acres of this family’s heritage.

Vicki’s brother, Bill Handel, is a botanist for the Illinois Natural History Survey and has been actively helping them manage the property with controlled burns, invasive species control and planting nectar and native pollinator plant species. One of their major challenges is combatting the spread of black locust trees which contain several toxic components in its leaves, stems, bark and seeds. Although native to the Appalachian mountain slopes, in the Midwest, it invades thickets and old fields crowding out the native vegetation of prairies, oak savannas and upland forests, forming single species stands. It does this by root suckering and stump sprouting forming a common connecting root system, making it an especially challenging job. Keep up the good work, Vicki, Robert, and Bill!

Louis and Mark Cagnoni - Ottertail Marsh

Louis and Mark Cagnoni of Durand have shielded 131 acres of wetland along the Sugar River in Winnebago County from development. A conservation agreement with the Natural Land Institute allows them to continue owning their property, while protecting the floodplain forests, sedge meadows and wildlife forever that they treasure at Ottertail Marsh. Louis Cagnoni purchased the farm on the Sugar River in 1974. His son, Mark, moved there two years later, and from the very beginning, Mark had the idea the land should be protected. “There was a marsh behind the house where I grew up, and when I was about eight years old, I started to study plants, dragonflies and other wildlife,” Mark said. Mark was aware that marshes and wildlife along the Sugar and Pecatonica rivers were rapidly disappearing. To enhance the wetlands on the farm, he raised plants such as cord grass, tussock sedge and sweet flag to plant there. He worked on his own for years, then got some help by enrolling the tillable acres of the farm in the U.S. Department of Agriculture’s Conservation Reserve Program. He also worked with the Sugar-Pecatonica Rivers Ecoyststem Partnership and NLI to secure a small grant to help restore native vegetation and install a water control structure in 2002. Before long, Mark saw Blandings turtles, little green herons and his much-loved river otters returning to the areas he restored with native vegetation. “I chose the name Ottertail Marsh because my interest in otters began as a child at Ottertail Lake in Canada,” he said. Mark and his father chose to use the conservation agreement to protect their property, because they will continue to own the land, and they are getting some equity from the property. They can sell it or leave it to someone in their wills, but it will never be cleared or developed. In exchange, they agree to protect it and provide stewardship of the wetlands.

Ottertail Marsh is part of a larger area of bottomland forest, marsh and wetlands along the Sugar River. It is designated as a Conservation Opportunity Area in the State Wildlife Action Plan, and as a Priority Area for Acquisition in the Boone-Winnebago Greenways Plan. The Sugar River Natural Area provides habitat for 260 species of birds and for 12 state-endangered and five state threatened species of plants and animals. Jerry Paulson, NLI executive director (2000-2013), said the Cagnonis were able to exercise their conservation rights with the help of grants from the Illinois Clean Energy Community Foundation and the Grand Victoria Foundation. NLI members also donated nearly $20,000 to complete the acquisition of the conservation easement and pay for cost of the legal agreements, appraisal and survey. NLI staff has the great privilege of helping landowners like Mark and Louis Cagnoni find ways to protect their properties. Our members and supporters, as well as the landowners, are fundamental to the process. All are among the most dedicated and conservation-minded people in our region.

Durward-Hardin Farm

The major thrusts towards long-term stewardship were initiated by Lloyd and Ruth Durward, who bought the farm from Lloyd’s mother, Elizabeth Edlund (married to Andrew Durward), in the mid-1930s. Lloyd worked with the depression-era Civilian Conservation Corps to establish waterways in the tilled fields and stabilize the bank along the creek which runs the length of the property. He incorporated, what were at the time, innovative practices such as crop rotation and contour farming into his agricultural operation. He planted windbreaks to encircle the farmstead and reseeded grass to rejuvenate soil on eroding hillsides. He encouraged and enlisted other farmers in the endeavor to spread conservation practices.

In the next generation, Lloyd and Ruth’s daughter Marjorie and her husband Harold Hardin continued these efforts as well as expanded them by establishing terraces in steeper fields and maintaining dikes along the stream bank, Marjorie maintained these projects and practices for three and a half decades subsequent to her husband’s death. She also seeded and maintained plots of prairie grass, as well as maintained a spring-filled pond that she had excavated several decades earlier. During her terminal illness, in 2001 she worked with the Natural Land Institute to establish a conservation easement on the property and ensured that the property would continue to be available for farming with some conservation practices in place, along with a stipulation that approximately fifty acres devoted to prairie grass and filter strips would continue to be maintained.

Marjorie passed the farm on to her children Sarah Hardin, Ruth Doocy, and Steve Hardin, and their families (including Christina and Laura Doocy, and Paul Hardin-Specht) who have attempted to maintain her work by coordinating two major stream bank stabilization efforts, as well as initiating some new projects. With cost share and rental from the CRP program, they have overseen the establishment of 8.9 acres of stream bank buffer strip. In addition, with cost share from the federal EQUIP, they are coordinating the reforestation of about thirty-five acres of environmentally sensitive land with hardwood trees.

The 272 Durward-Hardin Farm includes prairie species such as Pale Purple Coneflower, Wild Quinine, Grey-Headed Coneflower, Big Bluestem, Side-Oats Gramma and wetland species such as Spotted Joe-Pye weed and Red-Osier Dogwood.

Corliss and Russell Kerr

The Corliss and Russell Kerr family of Morrison worked with the Natural Land Institute protect its 379-acre farm in Whiteside County from development with a conservation agreement that was completed in December 2008. It protects the home farm purchased by Corliss Kerr’s great-grandfather in 1871.

“There were actually two goals behind this easement — protecting the agricultural acreage that has been in our family for more than a hundred years and preserving the land that my parents acquired 40 years ago and restored with natural areas,” said Jane Kerr, the third generation to treasure the farm. “My dad had grown up wandering through woodlots and wild areas, and purchasing the land was one of his dreams.”

Corliss Kerr said she and her family want the scenic vistas to remain for future generations to enjoy. “While our local area isn’t currently under intense development pressures like some urban-edge communities, that may not always be the case. We’ve always felt it’s important to maintain the natural areas and agricultural uses of this region. The conservation easement means that this property, that has been carefully stewarded for so many generations, will never be turned into stone quarries or golf courses, junkyards or housing developments, huge meat factories or ethanol mills.”

Mrs. Kerr said the family is happy that their neighbors and the community will benefit from their efforts. “We hope many of our neighbors will realize that they, too, can easily protect their farms and take advantage of the tax benefits of donating an agricultural conservation easement,” she stated.

Corliss Kerr’s father, Harvey C. Cobb, was a founding member of the Whiteside County Soil and Water Conservation District when they organized in July of 1944. He used terraces and contour farming methods, and later Russell Kerr added minimum tillage and no-tillage practices.

Forty-six acres on the Kerr farm are enrolled in the Conservation Reserve Program and are planted to black walnut trees and cool season grasses. Ninety-one acres are forested with black oak, red oak, black walnut and black cherry. Native plants, including little bluestem, thimbleweed, bush clover, asters and goldenrods, grow in a small prairie remnant on the edge of a woodland area. Rick Lawrence, former project director for the Natural Land Institute, helped the Kerrs create the agreement that protects the conservation values of their land. He said, “They will continue to own the property, they can sell it or leave it to heirs, but it will never be developed. They agree to continue to use conservation farming methods and maintain the forests and prairie that they love.”

Silver Creek Biodiversity Preserve: Tarbox Unit

A fifty-acre tract of woodland and grassland has been preserved at the headwaters of Silver Creek in Ogle County, Illinois, in a cooperative project between the Natural Land Institute and the Northwest Illinois Audubon Society.

The property was donated to the Northwest Illinois Audubon Society (NWIAS) by Mrs. Joanne Styles, a retired school teacher from Leaf River, Illinois. The Audubon Society then donated a conservation easement to the Natural Land Institute to insure that it will remain protected forever. At Mrs. Styles request, this newly-protected natural area has been named the “Silver Creek Biodiversity Preserve: Tarbox Unit” in honor of her first husband, Hascy Tarbox, a professional wildlife artist.

The preserve is located in the rolling hills of the Rock River valley about two miles south of Leaf River. Most of the property is covered by a mature hardwood forest of oaks, hickories, elm, and walnut. Forty-six species of birds have been observed so far in these woods including the red-headed woodpecker, red-eyed vireo, wood duck, and American kestrel.

Silver Creek, a shallow, spring fed stream that flows into the Rock River cuts through the preserve. Water striders and tadpoles were seen flitting about the shallows in the late spring, and the throaty “burp” call of bull frogs was heard. Dolomite bedrock forms the creek bed and a little bluff lined with ferns and mosses lies where the creek has slowly carved the land away.

Two old agricultural fields near the center of the preserve are enrolled in the USDA’s Conservation Reserve Program (CRP) and have been planted in warm season prairie grasses. After the CRP contract expired the NWIAS began restoring these fields to an open oak-hickory savanna.

Joanne and Hascy Tarbox purchased the property as a young married couple in the early 1940s and maintained it as a wildlife refuge ever since. Each year the last day of school was a very special day for the students in Mrs. Tarbox’s elementary school class. It meant that each student had a chance to visit the property and look for frogs, birds, and wildflowers.

The plan is for the new Silver Creek Biodiversity Preserve to be open to the public and used for field trips and environmental education sessions, continuing Mrs. Styles’ long-standing devotion to teaching young people about the natural world.

The NWIAS awarded Mrs. Styles their 2012 Land Stewardship Award at their annual banquet. The award is given annually to an individual with an outstanding commitment to the fields of land stewardship and the preservation of biodiversity. Shortly after receiving the award, one of Mrs. Styles’ former students approached her and told her how much she enjoyed visiting the woods as a child and how glad she was to see those woods protected.


In the summer of 2016 Ryan & Sadie Perkins became the newest addition to NLI’s family of Heritage LandKeepers when they put nearly 3 acres of buffer to the Jason Briggs Wetland that is part of a large complex of wetlands along the East Fork of Raccoon Creek, into a permanent conservation easement. The entire complex contains wet prairie, sedge meadow, marsh and calcareous fen, including the Jason Briggs Wetland which had been named in honor of Jason Briggs, a leader in the reorganized Church of Jesus Christ of Latter Day Saints after the death of Joseph Smith, Jr. in 1844. Briggs opened a church across the road from the spring, and many years later the Church of the Latter Day Saints purchased the property to preserve it as an historical site commemorating Brigg’s revelation from God. A sign placed on the wetland commemorates Jason Briggs and the historical significance of the site to the Church.

This entire wetland complex was the first acquisition of land in a 215-acre project area along the East Fork of Raccoon Creek that had been identified by the Wisconsin Department of Natural Resources as an important natural wetland. NLI purchased the wetland complex in 1994 using Wisconsin Knowles-Nelson Stewardship Funds for half of the cost, and The Prairie Enthusiasts raised the money for the remainder. This grant contractually requires that the Briggs Wetland be designated by the WDNR as a State Natural Area. NLI then transferred the property to the Prairie Enthusiasts which continues to manage the wetland complex.

Ryan & Sadie were purchasing the property from the Potters who had a temporary easement with NLI on almost 3 acres of the property, and generously agreed to the permanent protection of this important wildlife and natural area buffer. Ryan is an avid outdoorsman and wants to bring his children up in a rural, natural environment.

The Protected Property, although not a natural area itself, provides an important buffer to the perennial springs that feed the creek and the calcareous fen on the Jason Briggs Wetland. It helps to maintain the high water quality in the creek that supports a diverse fish population. The cool-cold, clear water with high dissolved oxygen needed for brook trout is maintained by the springs and groundwater that feed the creek. The stream is classified as an “Outstanding and Exceptional Water” by the Wisconsin DNR and is the only brook trout stream in the southern tier of counties in Wisconsin. It has a rich assemblage of fish species, including a healthy population of Redside Dace, a fish listed as being of “Special Concern” by the WDNR that is found only in small streams with cool water pools and quiet riffles with substrate of clean cobble, sand or bedrock in glaciated regions.

Important birds that have been observed in the wetlands include belted kingfisher, eastern kingbird, sedge wren, swamp sparrow and common yellowthroat. Virginia rail use the wetland and Great blue herons feed in the creek. It is likely that sandhill cranes, sora rails, willow flycatchers and northern harriers also use the area.
