This weekend includes physical yoga practices, meditation, hiking, and dharma discussions. Some of our sessions will be held outdoors as Mother Nature allows. Both yoga and nature can help us open gateways to our innermost selves. When we soulfully touch nature, we touch ourselves. By going outward, we journey inward finding a soulful connection to spirit and the divine.

Included in the retreat: two nights of lodging(dorm-style with private bathroom), 6 meals, 4 sessions with the instructor, Gigi Heinz. The retreat begins with dinner at 5 p.m. on Friday and ends with lunch on Sunday.

Wildlife Wednesday: Porcupines
January 15, 2025 - 4-5​ p.m.

Discover wildlife that calls Wisconsin's Northwoods home through Wildlife Wednesdays at Treehaven! Join us monthly for this FREE all-ages program series, and explore the natural history of each month's focus animal through interactive activities, guided walks, and/or specimen observation. From fur to feathers, woods to water, predator to prey, and more, experience the diversity of the animal world right outside our windows!

With about 30,000 sharp quills covering its body, a North American porcupine is a sight—or sensation—seldom forgotten! Damages caused by porcupine defenses, foraging, and other natural behaviors often cause them to be viewed with frustration, but there is much more to discover about this unique rodent and its role in Northwoods ecosystems. How does a porcupine survive winter without hibernating? What Northwoods predators are up to the challenge of preying on this formidable foe? And, most importantly of all, what do you call a baby porcupine? Through an indoor presentation with specimens, explore the life of a porcupine, discover the answers to these questions and more, and learn tips on observing perplexing porkies in the wild this winter!

Meet at the main entrance (double doors with Treehaven sign). Doors will open at 3:50 PM, talk begins at 4:00 PM. This is a seated, indoor presentation that will take place in the lower auditorium, Sylvester. All ages welcome, but children must be accompanied by an adult at all times.​

Subnivean Zone Family Program
February 22, 2025 - 9-11:30 a.m.
Registration Closed

Surviving the winter is "snow" joke! Some animals rest through winter or even leave entirely, but what about those that don't? How do they survive?

Join us for a fun, all-ages program to explore how Wisconsin animals use the subnivean zone, a unique habitat formed out of the winter snowpack! Subnivean means "under the snow", and mammals, birds, amphibians, insects, and more each have different ways of using this space to meet their needs. Learn how animals like voles, weasels, ruffed grouse, salamanders, and even spiders survive the winter thanks to the subnivean zone, then venture outdoors to search for signs of subnivean critters. Bring it all together by exploring the insulating properties of snow as you craft your own snow shelter!

Meet at the main entrance (double doors with Treehaven sign). Program will begin with a brief presentation indoors, but most activities will be outdoors. DRESS WARM, it will be cold! Layers, hats, gloves, and snow boots recommended. There will be a small hike (less than .5 mi) to/from the shelter building area with some light inclines. Shovels will be optionally provided to assist in snow shelter building.

This event is a great experience for the whole family, and all ages are welcome to come play and learn in the snow! Children under 18 must be accompanied by an adult at all times.

Cost: $5 per adult, $2 per child.

From fur to feathers, woods to water, predator to prey, and more, experience the diversity of the animal world right outside our windows!

Each winter, snowshoe hares go through a fascinating transformation as their fur turns white to help them blend in! Keep your eyes peeled as we gear up with our own snowshoes and venture out on a naturalist-led snowshoe hike to some of Treehaven's best habitats for snowshoe hares, learning about their lifestyle as we go. Observe tracks, signs, and perhaps even a hare or two as you discover what makes them a key prey species in northern forest ecosystems. Warmer winters are proving especially difficult for the survival of snowshoe hares, which impacts their predators too—so what can we do to help?

Meet at the main entrance (double doors with Treehaven sign). DRESS WARM, it will be cold! Layers, hats, gloves, and snow boots recommended. Hike will cover just under 1 mile, with some stops along the way. Terrain will be mostly even, but a few moderate inclines, narrow paths, and possible slippery patches will be encountered.

From fur to feathers, woods to water, predator to prey, and more, experience the diversity of the animal world right outside our windows!

Introducing the silliest bird of the Northwoods—the American Woodcock, also known as the timberdoodle or bogsucker! Well-known for stunning moves on both the ground and in the air, there is much to discover about this odd little shorebird of the forest. Learn what curious traits and behaviors of the woodcock have fascinated observers for generations, including conservationist Aldo Leopold, during a casual fireside chat at scenic Dragonfly Pond!

We'll listen for their "peent" calls and keep our eyes to the sky in search of their iconic springtime courtship flights!

Meet in the main parking lot. There is a brief (less than a quarter mile) walk to the pond across the parking lot and down a short trail. We will walk to the pond as a group; attendees with mobility concerns are welcome to follow behind in a vehicle and park in a smaller lot near the trail entrance for a reduced walking distance. Trail is overall wide and even, but the fire ring is located on a hillside so there will be a partial incline when departing. Talk will occur outdoors seated in a shelter around the fire ring. Participants are welcome to bring flashlights/headlamps for use as it gets dark. Cameras are also recommended for photos of the pond, sunset, and potential woodcocks in flight! All ages welcome, but children must be accompanied by an adult at all times.
