Look up the Red-eared Slider on the Internet and you will find many references to caring for them as pets. They are the most popular turtles when it comes to having one for a pet. This is all well and good if they are cared for as they should be. But when people tire of them they don't know what to do with them. Unfortunately, some take them out to places where there are bodies of water and turn them loose, not thinking about the effects of releasing invasive species into an area where they may affect the balance of nature. Such is the case in Delta Ponds where the Red-eared Sliders seem to be taking over from the native Pond Turtles. This could have a serious effect on the population of the Pond Turtles, who lose habitat and food to the larger, more aggressive Sliders. One does have to admit that they are great looking turtles, and much more colorful than Pond Turtles.
