On September 10, 2018, after many months of planning and countless meetings and discussions, something big began happening at Goose Pond. Two bulldozers, a large backhoe, and an excavator rolled in Monday evening ready to start moving thousands of cubic yards of soil out of the canary grass dominated wetland. For the next four days, LMS construction worked long hours creating seven wetland scrapes for Goose Pond Sanctuary.


What’s a wetland scrape?

Wetland scrapes are essentially isolated, shallow depressions that fill with water during part of the year, especially in spring. They’re often constructed to enhance wetlands that have filled with eroded silt from farm fields. Creating wetland scrapes effectively establishes diverse habitat for waterfowl, marsh birds, shorebirds, amphibians, and aquatic invertebrates.

Goose Pond is a beautifully restored wetland just next door, but waterfowl breeding pairs like to be secluded and have their own territory to avoid competition with other pairs. As a result of creating these scrapes, we expect gadwalls, mallards, blue-winged teal, northern shovelers, northern pintails, and green-winged teal to find peace and contentment in their new nesting habitat. Shorebirds such as killdeer and spotted sandpipers are able to wade around in the shallow waters, searching for food. Other birds, like the barn swallow, will use exposed mud flats to build their nests.

Chorus frogs, spring peepers, leopard frogs, eastern and Cope’s tree frogs, American toads, and eastern tiger salamanders will breed in the water filled depressions. We plan to conduct surveys to determine what amphibians are taking up residence in our scrapes. Many animals, like the white-tailed deer, will use the wetland scrapes as a water source.

Because we have scattered scrapes of varying kinds at Goose Pond Sanctuary, little microhabitats will form and allow for greater plant and wildlife diversity. Scrapes that are not circular create more shoreline edge, which is going to provide better cover, food, and resting area for wildlife. As Goose Pond goes through wet and dry cycles, having multiple wetlands will provide refuge for wildlife. For example, in periods of drought, a scrape at a lower elevation might still hold some water when ones at higher elevation do not. Animals will have access to this scrape at lower elevation and will be able to take refuge there until more rain comes.

The Process: The Planning

A gradual 8:1 slope creates different vegetative heights as the water level drops and rises. This means that food sources can stay around longer in a self-sustaining, dynamic community. Furthermore, a gradual slope allows invertebrates to follow water levels and concentrate in a remaining pool as the water level drops. This can then be an excellent, easy-access food source for wetland birds.

But a gradual 8:1 slope is not a cake-walk to achieve! Kurt Waterstrad from U.S. Fish and Wildlife Service, Louie Meister from LMS Construction, Mark Martin and Graham Steinhauer from MAS Goose Pond Sanctuary, planned the whole project out, from securing the necessary permit approvals (Kurt) to mowing and mapping out the site (Graham) and everything in between.

The Process: The Heavy Lifting

Then, beginning on September 10, Junior, Gus, and Joe from LMS Construction completed the enormous task of scraping out approximately 5,950 cubic yards and depositing it evenly across our upland areas. They carefully and professionally ensured that each scrape was at the correct depth, acreage, and slope ratio. The sight and sounds of heavy equipment working in the sanctuary was an odd, yet invigorating experience, knowing the promise of what those bulldozers and excavators held!

Graham Steinhauer, Jacqueline Komada, Mark Martin, and Bob Bennicoff hand-broadcasted 168 pounds of fall rye in the uplands where the soil was deposited to prevent erosion. The wetlands will be seeded this fall, using seeds that our staff and volunteers collect over the next few weeks (want to help? Click here!). Over the winter, we will create a plan for planting prairie shrubs for wildlife in part of the uplands.

There are unique annual wetland plants that we can establish in our scrapes, including smartweed, water plantain, and bidens. These will provide high energy food for waterfowl. Soft-stem bulrush and and river bulrush may be planted, but could also naturally colonize along the scrape edges.

We are thrilled to have this project in the works here at Goose Pond. As one of the highlights of the year, these wetland scrapes are just another way Madison Audubon Society is working to establish diverse and protected habitat for generations to come. Thank you everyone for your incredible support!

We want to give a special thank you to all of those who played a critical role in the success of this project: The Wisconsin Waterfowl Association provided funding through the North American Wetland Conservation Act grant. Both the U.S. Fish and Wildlife Service from the Wisconsin Private Lands Office and Madison Audubon Society also provided generous funding.

Stay tuned for updates!

Into the Nest: Defending the Nest

Into the Nest: Defending the Nest

Our last post shared some pretty intense videos of predation events at nests. In both videos all of the chicks got eaten, and the parents either fled or did not approach the nest while the predator was there. The badger and the 13 lined ground squirrel weren’t challenged as they made off with nestlings. It’s not always like this, though. It turns out that bird parents respond differently depending on who is trying to eat their chicks.

September 2018 Keystone Volunteers: Levi Wood and Peter Fissel

This dynamic duo has been responsible for organizing Madison Audubon’s expansive list of public, diverse, and fascinating field trips for years. Each fall, Levi and Peter sit down with a calendar, a grin, and a bag full of ideas for what types of trips we should host the following year, and who we might ask to lead them. Their large network of birding, butterflying, botanically minded cronies are persuaded into service, thanks to Levi and Peter!

In addition to planning out the types, locations, and dates of the 20-40 field trips we host each year, Peter and Levi often lead them too! They bring people to nature, and make birding, butterflies, and natural history things to explore openly and thoroughly.

Thank you to both Levi and Peter for the many hours you dedicate to Madison Audubon each year, in particular for this work, as well as all the other ways you contribute to our mission!

Into the Nest: Badgers gotta eat too!

Into the Nest: Badgers gotta eat too!

While adult birds and eggs are vulnerable during incubation, they are at even greater risk after chicks hatch. Most of our grassland birds are altricial as chicks, and need to stay in the nest long enough to be reasonably mobile when they fledge. However, chicks are also very vulnerable in the nest: they stay in one place, and the noise and activity surrounding the nest can attract predators. These birds need to balance the benefits of staying in the nest until they are able to fly to forage and escape predators with the potential risks of being found by predators while still in the nest.

Madison Audubon earns national land trust accreditation!

Announcing our new Land Trust Accreditation!

Madison Audubon is a non-profit that works to acquire, steward, and conserve land – in other words, a land trust organization. Back in 2012, we made a bold decision to seek national land trust accreditation, a mark of distinction awarded to organizations meeting the highest national standards for excellence and land conservation permanence. This was no easy undertaking. Indeed, of roughly 500 Audubon chapters in the U.S., there is only one other chapter that has received this distinction. We're proud to say that Madison Audubon is now the second nationally-accredited Audubon chapter and among an elite group of other land trust organizations around the country that have received this recognition!

WHAT IS ACCREDITATION?

The Land Trust Accreditation Commission, an independent program of the Land Trust Alliance, conducts an extensive review of an organization’s policies and programs. Think of it like an audit of how a land trust does business. It gets deep into the nitty gritty – policies, procedures, record-keeping, finances, governance, land stewardship, and so much more. So we’ve been working diligently to demonstrate that Madison Audubon meets rigorous standards for excellence, accountability, and permanence of our conservation efforts. If you'd like more information about land trust accreditation, you can find it here

Madison Audubon is honored to continue to protect the land we all cherish, and the species that rely on healthy ecosystems. Our heartfelt gratitude goes out to the many people who helped make national accreditation possible. And of course, we couldn't do any of this work at all without our generous, vibrant donor and membership base -- you are the heart of our work!
