Chaparral Prairie State Nature Preserve

Chaparral Prairie is a 67-acres state nature preserve with a three-quarter mile loop trail. Located in Adams County, it preserves a rare prairie habitat. Prairies are defined by the type of vegetation that grows in them. In general these plants are drought-tolerant, fire-tolerant and shade-intolerant. They originated in America’s Great Plains and moved eastward thousands of years ago during a centuries-long drought when this area was warmer than now. However as the climate cooled and normal rain levels returned, the prairie vegetation started to be replaced with moisture-loving vegetation that is more typical of eastern North America. In fact many ecologists believe that Ohio’s prairies would have disappeared but for the intervention of Native Americans. American Indians preserved these prairies by setting them on fire at regular intervals. These fires prevented shrubs and saplings from moving into the openings. However after the Native Americans were displaced, the settlers having European roots did not continue the land practices of the Native Americans, and the disappearance of the prairies accelerated.

There are a number of different types of prairie based on the level of moisture available to the plants. The one that became Chaparral Prairie is a xeric prairie (prounounced “ZERR-ic”) which basically means that it is a dry prairie. Prairies can either be dry because they are located in a region where there isn’t much rain, or because the soil isn’t able to retain moisture well. In the case of Chaparral prairie, a lot of the soil eroded away while farmers tried making the land agriculturally productive in the 1800s. The remaining soil has poor water-retention capabilities.

Note how parched this soil looks. But this was photographed this May when Ohio had been getting a typical amount of rain.

As you can see from a GPS trace of our hike below, the trail primarily consists of a loop, and it passes through both open areas and stands of trees. In order to prevent trees from completely taking over the area, the naturalists of the Ohio Department of Natural Resources have resumed the prairie-burning ways of the Native Americans. To make sure it is a controlled burn, the park service makes use of a fire break.

This is a GPS trace of our hike at Chaparral Prairie showing the Hawk Hill Loop Trail and the firebreak. The trace of our hike was made using Google’s “My Tracks” app.

Below you can see burn marks on the tree to the far right. Without periodic fires this prairie would disappear.

The trail, especially through the open areas, was wide and well-tended. Below you can see the mown path leading to the loop.

Since prairies are special because of their vegetation, let’s take a look at some of the vegetation visible in late May. One of the first novel plants that I noticed was the milkweed shown below.

Spider Milkweed (Asclepias viridis) — A milkweed more common in the south, its flower has green petals with contrasting purple stamen. Like many other milkweeds, it is a host plant for Monarch butterflies.

The plant below is called Rattlesnake Master because the seed pods were used as rattles by Native Americans; perhaps the rattle sounds like a rattlesnake shaking its tail? People also used to believe it could be used to treat snakebite victims, but we now know that’s not so.

This is the foliage of a plant known as “Rattlesnake Master” (Eryngium yuccifolium).

Here’s a closer look at the edges of the leaves.

Detailed view of the foliage of “Rattlesnake master” — note the spines on the edge of the leaves. Interestingly, the fibers in this plant were used in shoe construction by Native Americans in this area.

Rattlesnake master wasn’t blooming during our May visit, but when we returned in July we were able to view the flower.

One of the most noticeable plants that we saw while hiking in Chaparral Prairie was prairie dock. It formed a thick ground cover in certain regions of the opening. The trail below passes through a stretch of prairie dock.

The leaves of prairie dock are really large.

Since most plants in prairies bloom during the summer, we were there too early to see it in bloom. However we have photographed Prairie Dock in bloom at Gallagher Fen, so I will include a photo of its blossoms just to give you an idea of what it will look like this summer.

Since we were visiting in the spring, we didn’t get to see the prairie dock in bloom, but here’s a photo of prairie dock that I photographed at Gallagher Fen showing what the flowers look like.

Were you to visit in summer, you’d see many more plants in bloom. But one other that we saw while visiting in the spring was evening primrose.

We also noted a couple of species of oak that seem to be characteristic of the area: blackjack oak and post oak. Both species are moderately fire resistant. Blackjack oak grows slowly, but can tolerate relatively infertile soil. Post oak is drought-resistant.

I believer this is the leaf of a blackjack oak; it reminds me of a webbed foot.
Foliage of post oak (Quercus stellata); apparently the new growth of leaves in the spring can have a reddish cast. This was photographed in May, so this is not fall color.
