The painted turtle (C. picta) is the only species in the genus Chrysemys. [5] The parent family for Chrysemys is Emydidae: the pond turtles. Emydidae is split into two sub families; Chrysemys is part of the Deirochelyinae (Western Hemisphere) branch. [ 10 ]
The smallest member of Chrysemys, it is smaller than any of the subspecies of C. picta at about 10–14 cm (4–6 in) long. [8] Its top stripe is a prominent red, [9] and its bottom shell is tan and spotless or nearly so. [10]
British Columbia road sign. The decline in painted turtle populations is not a simple story of dramatic range reduction, such as the American bison.Instead, the turtle remains numerous and occupies its original range—it is classified as G5 (demonstrably widespread) in its Natural Heritage Global Rank—however, the settlement of North America has undoubtedly reduced its population density.
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

A gene drive could be used to eliminate invasive species and has, for example, been proposed as a way to eliminate invasive mammal species in New Zealand. [175] Briefly put, an individual of a species may have two versions of a gene, one with a desired coding outcome and one not, with offspring having a 50:50 chance of inheriting one or the other.
Exotic species control falls under the management of the U.S. Fish and Wildlife Service, which has been compiling and disseminating information about invasive species since 1994. Control of invasive species costs $500 million a year, but 1,700,000 acres (6,900 km 2) of land in South Florida remains infested. [5]
