Mountain pine beetle is becoming an increasingly more prevalent novel disturbance with much of Alberta’s pine forests. These beetles not only affect the host trees themselves but also the forest plant community as a whole, including soil pH. Not only is pH vital for plant processes by controlling nutrients available within the soil, but it also helps explain microorganism variation as well. Variation in microbes can have reaching implications on the processes performed by those microbes, such as decomposition of organic matter, nutrient assimilation into soil, and inorganic element transformations. Sixteen years ago, an experimental lodgepole pine forest was established to measure the forest's response to a mountain pine beetle attack. Within this forest four different treatments were applied, a 100% kill, a 50% kill, a clearcut, and a control. Having collected data in the summer of 2025, we were interested in comparing the pH of forest floor soil samples between the four treatments sixteen years after the simulated attack.
