Chapter 1 Ecological Restoration: Introduction
Video 1. Bill Hogseth: restored remnant prairies are complex.
Bill Hogseth, Wisconsin Department of Natural Resources restoration technician and active volunteer with the Prairie Enthusiasts, stands in a remnant dry prairie that he worked to restore in the lower Chippewa River area. A few years earlier, the place was degraded prairie, covered with a thicket of trees and brush.
Chapter 2 Pleasant Valley Conservancy: Restoring a Lost Landscape
Video 2.1. Kathie Brock: initial restoration efforts at Pleasant Valley
Kathie Brock tells why she and Tom bought the land and describes their initial restoration efforts, including removing easter red cedar (Juniperus virginiana). The tall grass waving behind Kathie is Indian grass (Sorghastrum nutans), which she and Tom sowed into an old ag field.
Video 2.2. Tom Brock: girdling and clearing trees from the East Basin
Tom Brock describes tree removal operations for the most recent prairie restoration area: the East Basin. It's hard to believe today that so much of Pleasant Valley Conservancy was utterly choked with trees and European buckthorn (Rhamnus cathartica).
Video 2.3. Kathie Brock: cutting, burning, and overseeding prairie
Kathie Brock describes cutting, burning, and overseeding the hillside prairie.
Video 2.4. Key steps in restoring oak savanna
Kathie Brock tells how the Pleasant Valley savanna was completely choked with trees. She explains key steps in restoring overgrown oak savanna, including overseeding of forms, which supplements the existing rain of seeds and accelerates the return toward oak savanna's naturally high number of plant species in small areas.
Video 2.5 Tom Brock: persistent efforts to eliminate common buckthorn
Tom brock stands on the dolomite ridge among large bur oaks (Quercus macrocarpa), where common buckthorn (Rhamnus cathartica) was once tall and thick. Those were removed, but, as often happens, many root masses, resprouted and new blackthorn plants grew from the abundant seeds. In this video, Tom Brock describes efforts to eradicate common buckthorn from this portion of the bur oak savanna.
Chapter 2 Pleasant Valley continued
Video 2.6. Kathie Brock: many other hillsides are restorable
Kathy Brock looks across Pleasant Valley. The Brock's savanna restoration was once as tree covered as most other hills in the region.
Video 2.7. Tom Brock: purple milkweed (Asclepias purpurascens), a Wisconsin endangered species.
Tom Brock describes how restoring a portion of the white-oak (Quercus alba) savanna resulted in the discovery of purple milkweed, a Wisconsin endangered species. Biologist Paul West identified it and Tome became interested in the population, which, through Tome and Kathie's attention is now one of the most significant in Wisconsin.
Video 2.8. Mark Leach: personal benefits of participating in restoration
Mark Leach comments on Tom and Kathie Brock and the benefits of exercising the brain.
Chapter 3 Manoomin: Restoring the Abundance of Wild Rice
Video 3. Mark Leach: the structure of the wild rice plant
Mark Leach describes a northern wild rice plant (Zizania palustris palustris) on the North Fork Flowage at Crex Meadows. This particular plant is growing out of the exposed soil during an intentional water drawdown.
Chapter 4 Bad River Watershed Association's Culvert Program
Video 4.1. Michele Wheeler: how some culverts block fish passage
Michele Wheeler describes why fish find it difficult or impossible to continue upstream through poorly positioned pipes.
Video 4.2. Michele Wheeler: restoration success at Troutmere Creek
Troutmere Creek is what restoration success looks like. Michele Wheeler describes how volunteers identified this culvert as a problem and how fish passage was restored without replacing the pipe.
Chapter 5 Partners Think Big: Lower Chippewa River Valley
Interactive Graph. Figure 5.4 Several forces influence how many species are in a place
The Equilibrium Theory of Island Biogeography helps us understand that the number of species on an island or habitat patch is the balance of two forces: immigration and extirpation. (Figure redrawn from MacArthur and Wilson 1967.)
