Utilize Buffer Zones as a Preventative Pond Maintenance Tool

Written by Industry Expert Daniel Hood, Wildlife & Fisheries Scientist

I have always been a fan of Benjamin Franklin’s saying “an ounce of prevention is worth a pound of cure.” Lake and pond management is a perfect example of this advice; preventing water quality problems at their source is often the most effective measure to help achieve long-term aquatic health. Community managers, golf course superintendents and private landowners interested in becoming more proactive in their maintenance approach may be intimidated by the many environmental variables and aquatic management strategies available to them. However, an easy and effective place to start is by creating and maintaining a shoreline buffer of native vegetation around their waterbody.

A proper buffer zone utilizes the well-established root system of native grasses and vascular plants to help protect the waterbody. The dense root systems and high stem count of an established native buffer are extremely effective at slowing the velocity of stormwater runoff and absorbing the excess nutrients contained within them. Runoff that is allowed to flow unimpeded to the pond edge can lead to erosion, resulting in sedimentation that may reduce depths in a lake or pond over time. Dissolved nutrients carried by stormwater runoff in the form of fertilizers, pet waste or grass clippings may result in harmful, unsightly algal blooms or other water quality problems. Dense buffer zones can also prevent geese from easily entering or exiting a pond to nest, feed, and leave droppings around the waterbody.

In order to effectively deter these water quality threats, plants within the buffer zone must be allowed to grow  their natural heights in a band at least 3-5 ft surrounding the pond. While buffers composed of native plants and vegetation should never be mowed, they will still require some maintenance throughout the year. The buffer can be trimmed annually to promote healthy growth and maintain its aesthetic beauty. Typically, it’s recommended to cut the buffer area no less than 18 inches, especially during the cooler season.

Flowering native plants can be selected to add seasonal color, as well as attract beneficial insects. Swamp milkweed and pickerelweed, for example, attract dragonflies that naturally prey on mosquitoes. Other common buffer plants include duck potato, blueflag iris, lizard’s tail and cardinal flower. A lake management professional can recommend additional plant species that are easy to maintain and native to your specific region.

From both an aesthetic and functional standpoint, it is important to distinguish between shallow, dense grass root systems of native plants and the simple, deep root systems of woody vegetation. Trees that are allowed to grow in buffer zones can shade out grass species and compromise pond dam structures. They may also attract undesirable rodents, like beavers and muskrats, which are known to build dams, damage shorelines, and chew through important power cables. To make a long story short, the removal of woody vegetation is crucial to helping prevent costly damage and ensure you pass your next stormwater management facility inspection.

A well-maintained buffer zone serves as an important, natural and proactive aquatic management strategy. A properly introduced and managed vegetative buffer can also help property owners and managers save money on annual pond maintenance costs, enhance property value, extend the lifespan of a waterbody and contribute to an overall improvement in water quality. Pairing the benefits of a native buffer with other proactive strategies like aeration, biological applications and nutrient remediation will allow your waterbody to flourish while serving as a beautiful long-lasting centerpiece for your home, golf course or community.
