The Negative Effects of Beaver Dams

Flooding is the most common impact caused by beaver dams. Flood water can be treacherous and destructive in many ways; from residential to commercial real estate, to land, plants and lumber. Various natural and man-made structures are frequently damaged by flooding caused by local beaver dams. Timber, agriculture, homes, buildings, roads, and more can be adversely affected by beaver obstructions. Read on for some common areas negatively affected by beaver dams.

Houses and buildings

Flood water can cause a substantial amount of damage to commercial and residential real estate. If beaver colonies live nearby, homes and buildings may be at risk of structural damage from flooding. Beaver dams create floodwaters that can overflow into backyards, parking lots, and even basements. Standing water can cause a long list of structural damage; everything from dry wall deterioration to mold growth. Beavers have also been known to gnaw on decks, patios, and other wooden structures around homes and buildings. This reduces the value of the building, as well as the physical appearance and aesthetics of a property.


Public roads are another area affected by beaver dam construction and flooding. Roadside ditches and drainage channels are perfect environments for beavers and dam building. Dams can not only flood roads and clog traffic, but can also cause asphalt erosion. All of these implications have caused car accidents, road closures, culvert and bridge repairs, and much more.

Farms and Crops

Agriculture can also be damaged by floods. Beaver dams can cause creeks, streams, rivers, and creeks to overflow their banks onto large tracts of farmland. This makes it impossible for farm equipment to access the land. Also, beavers will eat crops or cut them down for dam construction material. All of this can negatively affect the growth and health of plants and other crops on farmland. Homes near beaver populations have also fallen victim to gardens and plants uprooted by local beavers.

Trees and Ornamental Plants

Trees play a very important role in nature; and they play multiple roles in the lives of residential and commercial property owners. Beavers are also fans of trees and plant life. They gnaw at them and use them to build their dams that flood our streets and land. Eventually, these trees die; they then become a safety hazard because they can weaken and fall over. For commercial reasons, this can be expensive if beavers damage high-quality hardwoods. For homeowners, dead trees look bad and can fall without warning. Beavers can also damage trees by flooding the land. If the water doesn’t drain fast enough, it can kill the trees.

Damage to ornamental plants is another trademark of nuisance beaver populations. Ornamental shrubs, plants, shrubs, and small trees are common targets for beavers. This can be a frustrating and expensive problem for commercial landscapers, gardening enthusiasts, local parks, and more.

beaver control

In most states, a person is required to have a beaver control license or permit; or to catch beavers. It is illegal in most jurisdictions to capture, kill, damage, or hunt beaver. One legal approach to getting rid of a beaver problem is to hire a professional animal control company. A reputable animal removal business uses safe and humane catch and release strategies to get rid of pesky beavers. This is the best place to start when trying to eliminate a beaver problem. Qualified trappers maintain the proper equipment and training to quickly and effectively remove beavers from any property.
