{"Image DocumentName": "Environmental Issues Another issue is invasive species. Bark beetles have savaged Yellowstone pine trees, as well as many other western trees.", "Image ImageDescription": "Microscopic parasites render cutthroat trout to not feed normally. The parasite originated in Europe, and somehow ended up in Yellowstone Lake, in the park, where the cutthroat trout are native. An environmental issue with the park is the climate. The temperature has highly increased for 50 years (since the 1960s). The climate can greatly alter ecosystems. The temperature, especially nighttime, is higher than it was 50 years ago.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
