Known as ecosystem engineers, these flat-tailed rodents create elaborate dam structures that create a sanctuary for other individuals in the community. They are stubborn creatures that hyper-fixate on building their dams in a certain spot and will continue to build even if destroyed. Some benefits of beaver dams include:

• Increased diversity in species
• Flood mitigation
• Creating wetlands
• Improvement of water quality

As vital as beavers are to an ecosystem, they can also be a nuisance to stormwater engineers around Texas. This is a known issue for many infrastructures. Beavers can break into a gated storm drain and build a dam inside, clogging the drain in the process. An adjacent retention pond fills with water, and, as a result, a nearby infrastructure floods. Engineers usually find themselves in a perpetual war against beavers.

Like beavers, nutrias can cause a mess that must be dealt with. Nutrias are designated as an invasive species by the Texas Invasive Species Institute, hailing from South America. Their big teeth are responsible for millions in damage to cash crops like rice. They also feed on native species, which can cause:

• Less biodiversity
• Erosion
• Risk to endangered species

Erosion is especially a problem for detention ponds, which can be affected by nutrias’ heavy grazing of native plant species. Fewer native plant species can destabilize the soil and cause the detention ponds to fail. Nutrias are also known to burrow and create complex dens that lead to severe bank erosion and increased sedimentation. All of this combined can cause subsequent damage and flooding to nearby infrastructure.

Dealing with rodents of this size can be difficult. If possible, a good first course of action is to fence off the area. Cage traps can also be used to safely relocate the rodent, though not as effective with beavers, as they can return if they have a dam in the area. If all else fails, reach out to Texas wildlife professionals to deal with the rodent in question.

Below is a list of suggested contacts to deal with both Beavers and Nutrias:

• USDA’s Wildlife Services
• Texas Parks & Wildlife Department
• AAAC Wildlife Removal
