Tuesday, 8 April 2008, Half-Day Field Trips
Thursday, 10 April 2008, Full-Day Field Trip
Restoration Ecology and the University of Wisconsin Arboretum
Organizer: Kevin McSweeney
Date: Tuesday, 8 April, 12:00pm - 5:00pm
The University of Wisconsin Arboretum is centrally located in Madison, encompassing
1,260 acres on the southern shores of Lake Wingra. It includes the oldest
and most varied collection of restored ecological communities in the world,
including tallgrass prairies, savannas, several forest types and wetlands.

In the early 1930s, the land that is now the Arboretum was in cultivated fields
and pastures that had fallen into disuse. The university decided, early on,
to try to bring back the plants and animals that had lived on the land before
its development. In focusing on the re-establishment of historic landscapes,
particularly those that predated large-scale human settlement, the early leaders
of the Arboretum introduced a whole new concept in ecology: ecological restoration
-- the process of returning an ecosystem or piece of landscape to a previous,
usually more natural, condition. For example, the world's oldest restored prairie,
Curtis Prairie, occupies 60 acres just south of the Arboretum Visitor Center.
Many classic experiments on planting techniques and the use of fire in prairie
management took place here during the 1930s and 40s. At the Wingra Oak Savanna,
near the northwestern shore of Lake Wingra, there is a magnificent grove of
open-grown bur oaks.

The savanna is being restored by replacing the understory
of non-native trees, shrubs, and weeds with the grassland species likely to
have grown in the original savannas. There are also a variety of deciduous
woods and conifer forests, several which include ancient Native American burial
mounds. This half-day field trip will provide opportunities to visit the distinct
ecological communities that represent natural habitats of Wisconsin, learn
about the ongoing research a restoration activities led by university faculty
and students, and enjoy some of the 20 miles of trail that traverse the site.
You can visit the Arboretum

Military Ridge Prairie Heritage Area in southwest Wisconsin
Organizers: Christine Ribic and David Sample
Date: Tuesday, 8 April, 12:00pm - 5:00pm
This field trip to The Nature Conservancy’s Military Ridge Prairie Heritage
Area (MRPHA) near Blue Mounds, Wisconsin, will visit one prairie restoration
area and one experimental area to discuss issues of landscape-scale management
in an agricultural landscape.

The original native prairies and sedge meadows,
which covered approximately 3.1 million acres in Wisconsin prior to European
settlement, were largely gone by the early 1900s, along with much of their
associated floral and faunal communities. Currently, there is only 0.5%
of this native grassland system remaining in the state, and much of it is in
a degraded condition. Because so little grassland is in public ownership in
Wisconsin, much of the needed management for grassland plants, vertebrates
and invertebrates occurs in landscapes dominated by private ownership and agricultural land
uses. The MRPHA incorporates many of the concepts of large-scale grassland
management areas for managing grassland birds, and it provides unique opportunities
to conduct research and to gauge some of the impacts of landscape-scale management
on plants, animals, agriculture and human communities. Field trip fee includes
a box lunch.
Stop 1: The Nature Conservancy’s Thomson Memorial Prairie
Portions of this 300+ acre preserve are intact remnant dry prairie. Personnel
from the Wisconsin Department of Natural Resources will discuss the history
of grasslands within the region as well as point out prairie species. (Visit
Memorial Prairie website
Stop 2: Restoration projects on private land

The Conservation Reserve Program (CRP) fields of three landowners are involved
in a wooded fencerow removal project. The aims of the project are to determine
the influence of wooded fencerows on predators of grassland bird nests. Grassland
bird populations have been declining since the 1960s. These birds nest on the
ground and avoid nesting near woody vegetation. Also, many potential nest predators
concentrate their activities along edges. Therefore, we are measuring predator
activity and bird nest success at several sites for comparison between sites
where fencerow vegetation will and will not be removed. Researchers from the
University of Wisconsin-Madison will discuss the local history of grasslands
research and details of the current project.
Stop 3: Prairie Enthusiasts restoration project
The Prairie Enthusiasts are working on a prairie restoration west of the fencerow
vegetation study. The site contains several prairie plant species, as well
as non-native invasive plants that the Prairie Enthusiasts will show us. Management
techniques will be discussed.
Arboretum and Capital Springs State Recreation Area Bike Trip
Organizers: Janet Silbernagel and Tom Albright (UW-Madison).
Date: Tuesday, 8 April, 1:00pm - 4:00pm

Madison is located amidst a scenic glacier-hewn landscape and enjoys an excellent network of bicycle paths and routes. This bike trip is a great way to get a taste of both of these aspects of Madison. Starting at Machinery Row Bicycles, a short walk from the Monona Terrace, we’ll follow a 21-mile loop along several bike paths and bike-friendly roads, through urban, suburban, and rural landscapes. While the route is mostly flat, there are a few rolling hills, providing both challenge and reward. Along the way, we’ll pause to introduce riders to the UW Arboretum, which is known for its rich history of

ecological restoration – much under pioneering conservationist Aldo Leopold’s direction.
Other stops will be made along the Capital City State Trail, which traverses beautiful marshland, creek bottoms, fens, prairie, and pine and oak-hickory forests of the Capital Springs State Recreation Area. Participants should be prepared for cool April weather (average high: 52° F) and be fit enough to maintain a moderate pace (~12 mph), although we may slow down a bit on the hills! Fee covers boxed lunch (eaten before we meet), bicycle, lock, and helmet rental, state trail pass, and support vehicle just in case. If inclement weather causes cancellation, a refund (minus the lunch) will be issued.
The Landscape that Shaped Leopold
Organizers: Stan Temple, Scott Craven, Mark Rickenbach.

Nearby Sauk County has a remarkable concentration of ecologically important
features, and it hosts sites of great significance in the field of conservation.
Participants in this field trip will visit the landscape that influenced Aldo
Leopold and learn about its historical and contemporary significance for conservation.
The topographically varied Baraboo Hills–part of Wisconsin’s unglaciated
Driftless Area–are one of the largest forested areas in the ecoregion
and support a great diversity of plant and animal species.

The lower Wisconsin
River played a dominant role in the creation of this landscape and is the focal
point of a major landscape conservation initiative. Its tributary, the Baraboo
River, is now the longest mainstem of a major river returned to free-flowing
condition through dam removal. The landscape also includes the riverside home
of Aldo Leopold’s “shack” where he wrote A Sand County Almanac
and where the Aldo Leopold Foundation now promotes his conservation legacy.

Nearby, the International Crane Foundation is the world center for conservation
of cranes and the wetland habitats on which they depend. The tour will briefly
visit the Wisconsin River
and key locations within the Baraboo
. Longer stops will allow for walking tours of the International
and its collection of all the world’s cranes, and
the Leopold shack and surrounding Aldo
Leopold Memorial Reserve
. The tour ends at the recently constructed Aldo
Leopold Legacy Center, one of the “greenest” buildings in the
