Wildfires in the U.S. West are getting larger and more frequent, and recent studies predict wildfire size and frequency will only become worse with time. Previous studies explain the importance and value of visibility in national parks. Wildfires release pollutants like CO2, N2O, PM2.5, and ozone, all with different concerning environmental effects. The effect of the pollutants produced by wildfires has a negative impact on visibility, and as the frequency wildfires increases, park visibility worsens. This thesis examines the impact of wildfires on national park attendance, evaluating whether diminished visibility from wildfire smoke pollution may inspire visitors to instead travel to parks farther from the wildfire incident. To answer this question, multiple regressions using monthly park attendance, wildfire, and pollution data test several hypotheses are incorporated in this analysis. Results show that distance from a wildfire increases air pollution levels by -1.4655. Results also show that attendance and pollution are also negatively correlated at the significant coefficient of - 30898.6. This study also shows that distance from a wildfire incident affects attendance and that fires within 100 miles of a national park have a significant negative correlation to attendance while there is no significant change to national parks over 100 miles from a wildfire incident.
