Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material describes the grazed and cut-over land that was added to the Arboretum, including the effects of fencing out cattle.
[Illustration of a tree stump] Header: CUT-OVER AND GRAZED LAND was added to the Arboretum in 1910 [image of a cow's head with its tongue out]
Text and illustrations from top to bottom:
- [Depicted in stylized scroll] THE RECORD:
- 1. No big trees in this area [illustration of a tree with a large red "X" over it]
- 2. Many stump sprouts [sketch of stump sprouts]
- 3. Many aspens and big-toothed poplars [sketch of aspens and poplars]
- 4. Young oaks, many of the same age [sketch of oaks]
- INTERPRETATION of THE RECORD:
- 1. Aspens and big-toothed poplars grow in sunny places.
- 2. The even age oaks show by their annual rings that they started growing on the year that the Arboretum fenced cows from this area.
- 3. The wild flowers have returned steadily to this area. There was only thistles, milkweed, dandelions, and other tough ones, there when the cattle were fenced out. Now there are trilliums, spring beauties, blood-root, may-apple, and many, many, others.

Arboretum Landscape Teaching Aid Series: Forest Met Prairie (3.19510)
Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material is depicted in the shape of a bur oak leaf. It describes how a line of bur oaks indicates where the climax forest and climax prairie met.
Header: FOREST met PRAIRIE [illustration of grass and trees]
Text and illustrations from top to bottom:
- The Record
- 1. a curving line of bur oaks
- 2. the heavy corky bark of the bur oaks, in comparison with bark of red oak.
- 3. the change in soil profiles at edge of oaks this [illustration of soil] to this [illustration of darker soil]
- Interpreting the Record
- 1) Because bur oaks, with their corky bark were best able to withstand the fires that swept the prairies (often set by Indians) and
- 2) because bur oaks are best at withstanding dry prairie winds
- 3) because bur oaks are seldom found in the heart of the woods
- We Read that: this line of bur oaks marks the place where the climax forest met the prairie climax
