Does it stay or does it go: exploring seasonal influences on nutrients across topography in a Colorado mountain watershed
Abstract
Climate change is a current issue that impacts ecosystems and the natural processes within them. Through the variance of factors such as, temperature, precipitation and hydrology due to climate change key processes such as nutrient cycling are affected. This study focused on the movement of nitrogen in a Colorado mountain watershed. Through the measurement of various forms of nitrogen, i.e. nitrate and ammonium (NH4+ & NO3-) which are available to aid plant growth, found throughout the cycle and potential effects of climate change can be realized. Nitrogen amounts were compared with NDVI data, soil water content, near infrared photography and microclimate data to find any correlations that affect the nitrogen cycle and the amount of available nitrogen in the ecosystem. This study looked at a different way to view the Colorado mountain watershed. Over time NDVI values changed at both sites (Lower Montane and Lower Sub-Alpine). How NDVI changes over time varies and depends on the site specific conditions.
