A study conducted by the Montana State University showcases Yellowstone National Park and its encompassed area depicts that expanded population and density as well as altering climate are influencing the entire ecological health of the region.
Andrew Hansen, professor in the MSU Department of Ecology said that the study determined course in the order of 35 ecological important indications concerned with snow, rivers, forests, fire, wildlife and fish. Hansen also said that the human population has doubled and housing density has tripled in the Greater Yellowstone Ecosystem since 1970. And both are estimated to double again by 2050. Also the temperature has become warmer by 1.5 degrees Fahrenheit since 1950 and is indicative of rising by another 4.5 to 9.4 degrees Fahrenheit by 2100.
Hansen along with Linda Phillips has coauthored a paper titled Trends in Vital Signs for Greater Yellowstone: Application of a Wildland Health Index.” Hansen said that these alterations in land utilization and climate have minimized snowpack and stream flows, escalated stream temperatures, advocated pest outburst and forest diminishing, fragmented habitats, developed intrusive species and declining local fish population.
The study also showcased good news for the domain and some animals for which it is an abode. Huge mammals involving bear and elk are growing in numbers and are enlarging in range. Also something to adhere about is the new methodology the MSU scientists utilized called the Wildland Health Index, which proceeded in reader friendly report card.
