Hi Eric, thanks for your report. Bullfrogs are a major reason why young native turtles do not survive in Oregon ponds. In some areas, they eat 100 percent of young turtles.

I know you don't own or manage the ponds, but you might find it interesting that bullfrogs can be controlled them by letting ponds dry up in late summer, scooping bullfrog egg masses out of the water, trapping tadpoles or gigging adults. You have to be very careful that you don't harm the native frogs or salamanders or their eggs.

People can call the Oregon Department of Fish and Wildlife or the local county Soil and Water Conservation District. Here's some contact information for help with bullfrogs on their property.

Thanks for keeping an eye out for invasive species.
