The Wetlands of Floyds Fork

The Wetlands of Floyds Fork

One of the most popular areas of the Humana Grand Allee in Beckley Creek Park is the Allee Wetlands, and for good reason—the wetlands contains some of the most diverse plants and wildlife The Parklands has to offer. The area was specifically chosen to be preserved as wetland because it is one of the few places in the park with hydric soil. This soil type stays saturated for a long enough period of the year that it becomes anaerobic and promotes the growth of hydrophytic vegetation such as rushes, sedges, water lilies and cattails.

To create the wetlands you see today, the soil was dug out and tiered. Drains were then installed to bring in water from the pond behind Bell Barn, located just across the street. The water is filtered through drainage swales and a smaller wetland before it reaches the Allee Wetlands. The pond stays between two and four feet deep year round depending on rainfall. When the water level reaches a certain height, it drains into another swale between the Festival Promenade and the Signature Tree Grove. Seeds and plugs of many native, wetland plant species were then sown and planted to provide the flora you see today.

Some of my favorite plants include Rose Mallow (Hibiscus moscheutos), Creeping Water Primrose (Ludwigia palustris), and Arrowhead (Sagittaria latifolia).

If you aren’t a plant nerd like I am, the wildlife around the Wetlands is enough to keep you coming back. It is a very popular area for bird watching. I see some of the same faithful birders and photographers out there every week. Lately, there is hardly a day that I haven’t been circled by swallows while walking across the boardwalk, or had a Bobwhite quail stumble across one of the access paths in front of me. If you are walking through the area and whistle for a Bobwhite, you are likely to get an answer back.

On multiple occasions, I have even seen a Bald Eagle hanging out around the sports fields and in the large Ash tree in the Country Lane Walk. Other commonly spotted critters include gigantic Bullfrogs, a Muskrat or two living in a push-up at the south end of the pond and, of course, our resident ducks.

Last year, we brought in domesticated ducks to help control aquatic weeds and they quickly became the stars of the Wetlands. One of our team members even built a floating house to help keep them safe from predators. The two Muscovy ducks are currently nesting inside the house. So far they have two tiny little ducklings following them around and a few more eggs waiting to hatch inside the house.

Preserving the integrity of the area is a big concern. Invasive species are always trying to creep in and must be dealt with. Native wetland species provide an important source of food for wildlife. Many of the non-native plant species that try to take over offer little to no value and often out-compete the more valuable native species.

Erosion of the drainage swales that feed into the Wetlands is another constant battle. When soil erodes, excess nutrients flow into the water and can promote algal blooms as well as having a negative effect on the delicate balance of the ecosystem. To prevent further erosion, biodegradable jute netting was installed in the swales and live stakes were planted to help keep the soil in place. A live stake is a large hardwood cutting taken from a shrub, such as a Dogwood or Willow, that is planted in late Winter or very early Spring. They have no branches or leaves and look just like a big stick. The species I used included Ninebark (Physocarpus opulifolius), Elderberry (Sambucus canadensis) and Silky Dogwood (Cornus amomum). I also planted a few Black Willow (Salix nigra) and Silky Willow (Salix sericea) along the southern edge of the main wetlands to provide a little shade over the water and help with algae issues. The more sunlight a pond gets, the more likely it is to have a problem with excessive algae growth.

The Allee Wetlands is a real jewel in The Parklands. There is something special about the environment—the sights, the sounds, and even the smell of it. The diversity of life in this small area is spectacular and breathtaking. If you come to the park looking for plants, wildlife, solitude, or just somewhere the kids will enjoy, the Wetlands is what you’re looking for.
