The topic of this project is to examine the ideal habitat range of the Mountain Pine Beetle and see if there is a change present within a 5-year time scale. This is very important due to how successful the species seems to be at killing off un-prepared pine trees and turning entire forests into fuel for a wildfire. I ended up choosing this topic after hearing about how trees killed by the Mountain Pine Beetle (MPB) usually end up being part of a forest fire and they the species is starting to invade areas that have higher elevations and/or historically colder temperatures because of unseasonably warmer weather. This means that trees that are not adapted to dealing with the MPB are getting exposed and killed off by in influx of these insect invaders. I accomplished my goal by taking four factors I considered to be important to the MPB’s range, average temperature (for general survival of all life stages), the presence of Pine Trees (the MPB’s main focus of feeding and incubating eggs), and the elevation of Colorado (since very few things, even the very successful MPB, can live in higher altitudes), and the presence of previous wildfires (it’s understandably difficult to infect a tree when it is already dead and burnt). After preparing the average temperature, the presence of Pine trees, and the elevation rasters, I preformed a Fuzzy Overlay and created a “mask” of previous fires placed it on the overlay, creating my analysis. In terms of a conclusion, it appears that the range of the MPB has slightly increased or remained relatively stable for the time frame I selected (2015-2020). In the future, I would like to expand my time frame to get a better idea on how much, or any, change has occurred.
