Thinking About Adding Turtles to Your Pond? Read This First

Are Turtles Good for a Pond?

Turtles can be a normal and beneficial part of a natural pond ecosystem, but describing them as simply good or bad leaves out a lot of details.

Most freshwater turtles eat a mixture of plants and animals. Depending on the species, their diet may include aquatic vegetation, insects, snails, crayfish, tadpoles, carrion and occasionally live fish.

Here are some possible benefits of having native turtles around a pond:

• They consume a variety of food. Some turtles eat dead or weakened animals, insects and other organic material. This makes them part of the pond's natural food web, although they should not be treated as a replacement for filtration or regular pond maintenance.
• Some species eat aquatic vegetation. Plant-eating turtles may consume certain weeds and algae, but they may also eat desirable pond plants.
• They usually do not destroy healthy fish populations. According to the Iowa Department of Natural Resources, snapping turtles primarily eat dead fish, while the live fish they catch tend to be small and abundant.
• They add interest to the pond. Watching turtles swim, bask and move around the shoreline can make a pond feel more active and natural.

A native turtle that moves into a larger natural or farm pond usually does not need to be removed simply because it is there.

When Can Turtles Become a Problem?

A turtle that causes few problems in a large farm pond could be much more noticeable in a small ornamental pond.

Possible concerns include:

• Small or vulnerable fish may be eaten. Many turtles are not efficient hunters of healthy adult fish, but they may catch small, injured, sick or slow-moving fish. Even occasional losses can be upsetting when a pond contains expensive koi or goldfish.
• Aquatic plants may be damaged. Turtles do not know which plants you consider weeds and which ones you planted on purpose. Species that eat vegetation may damage water lilies and other ornamental plants.
• They may eat food intended for your fish. Turtles can learn where fish are fed and may begin competing for pellets or other pond food.
• Pet turtles add to the pond's biological load. A pond designed to permanently house turtles needs enough filtration and water volume to handle their waste. Adding animals without upgrading the system can contribute to poor water quality.
• Several turtles may gather in favorable habitat. A pond with abundant food, easy access and good basking areas can attract multiple turtles. Feeding visiting turtles makes them more likely to remain and can draw additional wildlife to the area.
• Snapping turtles require extra caution. Snapping turtles generally try to avoid people in the water, but they have powerful jaws and can cause a serious injury when handled, cornered or threatened. Keep children and pets away, and do not attempt to pick one up unless you are trained to do so.

The presence of one turtle does not automatically mean your fish, plants or pond ecosystem are in danger. Identify the species and watch what it is doing before deciding that it needs to be removed.

Do Pond Turtles Carry Salmonella?

Turtles and other reptiles can carry Salmonella bacteria even when they look healthy and clean. People can become infected after touching a turtle, its waste, its water or objects from its habitat and then transferring the bacteria to their mouth or food.

The Centers for Disease Control and Prevention recommends washing your hands with soap and running water after handling a turtle or anything from its environment.

Children younger than five, adults 65 and older and people with weakened immune systems face a greater risk of serious illness from germs carried by reptiles. Young children should not handle turtles or objects from a turtle habitat.

Additional precautions include:

• Do not allow turtles to move freely through kitchens or other areas where food is prepared.
• Do not clean turtle tanks, bowls or equipment in a kitchen sink.
• Supervise older children around turtles and make sure they wash their hands afterward.
• Do not kiss, cuddle or hold a turtle close to your face.

Federal regulations generally prohibit the sale or distribution of turtles with shells shorter than four inches as pets, although limited exceptions apply. The rule was adopted because small turtles have been linked to human Salmonella infections, particularly among children. The U.S. Food and Drug Administration administers this regulation.

Should I Put Turtles in My Pond?

You should not capture a wild turtle and move it into your pond. You should also never release an unwanted pet turtle into a backyard pond, lake, stream or other outdoor body of water.

Wild turtle populations can be harmed when adult turtles are removed from their natural habitat. Released pets may spread diseases, compete with native turtles or establish populations outside their natural range.

Red-eared sliders are a good example. They are native to parts of the United States but have become established in other areas after being released or escaping from captivity. The U.S. Geological Survey warns that releasing nonnative animals can cause environmental harm and recommends safely rehoming unwanted animals.

A legally owned pet turtle may be kept in a properly designed outdoor pond or enclosure, but this requires more than placing the turtle in an existing decorative pond.

A permanent turtle habitat may need:

• An escape-resistant barrier around the entire enclosure
• Clean water with adequate filtration
• Safe and easily accessible basking areas
• Areas where the turtle can leave the water completely
• Protection from dogs, raccoons and other predators
• Conditions appropriate for the turtle's species and adult size
• A safe plan for cold weather if the species cannot remain outdoors in your climate

Check state and local wildlife laws before obtaining or housing a turtle. Rules governing the capture, possession, sale, transport and release of turtles vary by species and location.

What Should I Do if a Wild Turtle Is Already in My Pond?

In many cases, the best response is to leave it alone. A native turtle may visit temporarily, use the pond as part of a larger territory or leave after conditions change.

Follow these steps before taking action:

• Try to identify the species. A painted turtle, slider, softshell turtle and snapping turtle can have very different diets, behaviors and legal protections.
• Do not feed it. Feeding encourages the turtle to remain near people and may attract more wildlife.
• Watch for actual damage. A turtle resting on a rock is not proof that it is eating your fish or destroying the pond.
• Keep children and pets away from snapping turtles. Give the turtle room to leave and never grab it by the tail.
• Contact your state wildlife agency when help is needed. A wildlife professional can explain the rules and recommend an appropriate response for the species involved.

Do not trap and release a turtle somewhere else without guidance. Moving a wild turtle away from its home can reduce its chances of survival, and capturing or transporting certain species may be restricted.

The U.S. Fish and Wildlife Service advises people not to remove wild turtles from their habitat or move them to a different location. Unwanted pet turtles should be rehomed rather than released.

So, Are Turtles Good or Bad for a Pond?

A native turtle that enters a pond on its own is usually just another part of the local environment. It may eat some plants or small animals, but one visiting turtle is unlikely to ruin a healthy pond.

Intentionally adding turtles is more complicated. Do not capture wild turtles or release pets into an open pond. Anyone who wants pet turtles outdoors should create a secure, species-appropriate habitat and confirm that keeping the animal is legal in their area.

For most pond owners, the best approach is to enjoy native turtles that visit naturally, avoid feeding them and step in only when there is a documented safety or pond-management problem.
