Released yesterday, the National Park Service’s 2011 Yellowstone National Park
Natural Resource Vital Signs
 report says that not only have the numerous plans to remove invasive species and protect grayling and pure strains of native fish not been working, but that non-native fish species numbers are actually on the rise.  “The number of [lake trout] caught per 100 meters of net in one night (catch per unit of effort) has been rising since 2002, suggesting that the population has beenincreasing faster than the fish are being removed.”
