In 25 years as a beaver manager and researcher I have seen hundreds of attempted solutions to beaver-human conflicts. In quality and value, none compare to Skip Lisle’s elegant, original flow device designs. Highly effective, durable, and sensitive to the many ecological considerations involved, they are a reflection of his broad knowledge of construction, beavers, and wetland ecosystems. They are pure landscape art!Dr. Andrzej Czech
Before Skip arrived, I watched fish swimming over the town road by my house. Skip is one of those rare people with both a fine mechanical imagination and a profound understanding of animals, particularly beavers. He is totally devoted to doing the best possible job, and is tireless in his attention to detail. Each flow device he builds is tailored to perfectly match the unique characteristics of a given site. His devotion to high-quality workmanship is a pleasure to observe. The road will never be fish habitat again.Elizabeth Nields
It has been my pleasure to know and work with Skip Lisle for nearly twenty years. Skip created many of the innovative technologies used today to humanely resolve conflicts with beavers. He continues to take his designs to creative new heights based on his intimate knowledge of beavers and the wetlands they create. He is an environmental entrepreneur providing long-lasting remedies for flooding and other conflicts, which save money well beyond the costs of alternative, short-term responses such as killing and dam removal. Skip has long been a leader in educating the public and advocating for the beneficial environmental services provided by live beavers. He is truly one of the founders of the humane approach to living with wildlife that strives to make the world a better place for people and wild animals.Dr. John Hadidian
Skip Lisle offers that rare combination of "can-do" competence, creativity, and courtesy. He ably tamed our beavers with promptness and professionalism. Our California town, Martinez, still fondly remembers the man from Vermont, and his solution to save our Downtown!Mark Ross
Historically, a trapping-based “defense” of Elbow Pond Road has periodically eliminated resident beavers, and associated ecological values, but not property damage. Newly arriving beavers have ensured that many yards of gravel—and thousands of tax dollars—have washed away into downstream wetlands, closing the road for months. When the road was re-built, at great cost, the expensive new culverts were also immediately clogged. The obvious inefficiency of this approach forced us to look at other options.
It’s a big deal to find a solution to constantly blocked culverts. Thanks to Skip Lisle, we have done just that at a small fraction of the money we have previously poured into road repairs (what cost would the future have brought?). We are delighted to now have healthy, beaver-created wetland ecosystems and a long-lasting system in place that reliably prevents damage to the road and the town budget.Victoria Mishcon
The Beaver Deceiver Skip Lisle engineered and installed for our wildlife impoundment is working well. After 20 years of beaver problems, less than satisfactory solutions, and much backhoe work, we’ve finally been given a break. Thank you, Skip!Peter Winne
I first met Skip in his capacity as a wildlife/wetlands biologist for the Penobscot Indian Nation in the 1990s. I was immediately impressed by the depth of his knowledge of beaver ecology, his passion for the work, and his enthusiasm and willingness to help a sister tribe protect our roads from flooding while keeping our beaver populations and beaver flowages intact. Wetlands and, in particular, culturally significant wetland plants such as muskrat root and sweet grass, are a very important tribal resource. Skip’s skills have been invaluable in protecting these values. He’s the best at what he does! I highly recommend his services.Sharri Venno
Skip has all of the qualities one looks for in an individual and a contractor. His integrity and incredible knowledge base allow him to solve beaver management issues in a very professional manner.Jack Gleason
Skip’s devices and designs are great resources for our town. It is the best of both worlds for animals and humans. This is the solution for providing habitat for wildlife and protecting roads at the same time.Tim Higgins
Skip has taken an important and effective management tool and rolled it out in a big way. Because of his dedication to the proper management of wetlands and beaver, many thousands of wetland acres have been protected with untold benefits to all the species that use these areas. His work is inspirational!!John Banks
Skip is the creative mind behind the best and most cost-effective solutions to managing beaver impacts where they conflict with human interests.Dr. Duncan Halley
Skip, thank you for your follow-up. I've grown unaccustomed to people who stand by their work. What a refreshing change of pace.Dr. Lance Hellman
An engineering firm estimated that it would cost $125,000 for us to drain our pond (while killing the fish) to install a water-level-control device. Luckily, we found Skip Lisle who came and delivered: he solved our beaver issue for about 1/100th the cost without draining the pond. When, after seven years, there was a minor problem, Skip responded within two hours and was at our house the next day to fix it. Passionate and ingenious, Skip solves problems without hurting the environment, or breaking the budget.Christopher Vroom
Skip Lisle is the leader in non-lethal beaver management techniques. We called upon him to lead our workshops on flow device construction because his structures are the best and most cost-effective available. His detailed hands-on approach kept the audience engaged and gave us a clear idea of what is involved in this work. We received very positive feedback from participants.Amy Chadwick
There is a reason that Skip has never had to kill, or otherwise remove, a single beaver in order to solve hundreds of conflicts around the world. His skill, knowledge, and commitment level is off-the-charts. For us, that has saved our road and translated into a far richer, more interesting, and animal-filled wetland. It has a spectacular beaver lodge as a centerpiece, and is dissected with beaver trails that spread like veins across the aquatic vegetation. In its isolated, seacoast locale, it likely has an even greater ecological importance than average wetlands. The abundance of wildlife in the pond also provides entertainment for the numerous people who stop and look while using the abutting town road as a walking path.
In addition to providing an incomparable economic and ecological service, Skip is a great pleasure to work with and to learn from. Take advantage of this opportunity!Dr. Carol Richards
Working with Skip on our flow device project became a memorable community event. It attracted many curious visitors, including school groups. Thanks to his broad knowledge, and generous sharing of it, everyone went away with a better understanding of wetland ecology and the nature of thoughtful, effective problem solving. In addition, an expensive conflict was ended and, with the need to kill the beavers eliminated, a rich ecosystem (and beaver-viewing opportunity) was preserved.Dianne Rochford
After reading about his beaver work in Northern Woodlands magazine a few years ago, I contacted Skip about a possible guest visit to my 7th grade science classroom. He gladly accepted the invitation and has been an annual speaker ever since. My students always love his visit. They anxiously await his arrival with great anticipation after watching the Animal Planet episode, “Leave it to the Real Beavers,” that features Skip. His classroom presentation captivates them with his dynamic style, unsurpassed knowledge of beaver history and ecology, true-life stories of beaver encounters, and photos of flow devices that he has invented and installed all around the world. Of all the guest speakers I’ve had in 31 years of teaching, Skip Lisle is at the top of the list.Pete LaFlamme
It takes a creative and dedicated natural scientist/engineer to successfully deceive beavers as they alter the landscape by cutting trees, building damns, and creating ponds. Skip Lisle has a passion for, and depth of knowledge of, beaver ecology, a strong desire for beavers and humans to coexist peacefully, and an exceptional knack for underwater engineering.
For many years, Skip has volunteered a day of lecture and field experience for our Wetland Ecology and Conservation class at the University of Maine. His enthusiasm is contagious and students are captivated by the site-specific modifications that are made to each Beaver Deceiver in order for beavers to maintain residency in close proximity to fully functioning culverts, roads, and other human infrastructure. After spending a day with Skip, our students have a newfound respect for both beavers and a human who would do so much creative work to ensure their conservation. He is a hero to the wetland ecology community.Dr. Aram Calhoun, Director, Ecology and Environmental Sciences Program
