Factors recorded for Western Pond Turtle declines include the following: (1) habitat degradation in parts of its range (Pilliod and others 2013); (2) altered or eliminated stream habitat due to dam construction (Holland 1994); (3) spread of exotic competitors like the Red-eared Slider (Trachemys scripta elegans) (Spinks and others 2003; Kraus 2009; Global Invasive Species Database 2010); and (4) non-native and overabundant predators such as American Bullfrogs (Lithobates catesbeianus), Largemouth Bass (Micropterus salmoides), Raccoons (Procyon lotor), Striped Skunks (Mephitis mephitis
), Black Rats (Rattus rattus), and Coyotes (Canis latrans) (Moyle 1973; Holland 1991a, 1994; Hays and others 1999).
For example gray wolves (Canis lupus) have adapted facial color patterns that allow group communication in darkness during attacks on prey (Asa and Harrington, 2003), and the white and black aposematic coloration on striped skunks (Mephitis mephitis
) deters predators by signaling their potential to spray offensive and potentially harmful fluids (Hunter, 2009).

The hooded skunk (Mephitis
macroura Lichtenstein, 1832) usually is found associated with "streamside vegetation...stream courses where they prefer rocky ledges or tangles of streamside vegetation..." (Schmidly and Bradley 2016:251).
