Abstract

The montane meadows of the Sierra Nevada embody a dynamic habitat of aquatic and vegetative ecosystems that provide valuable services to humans, most importantly water regulation. Healthy and thriving meadows have the ability to improve ground water quality because their unique vegetative ecosystem absorbs and filters out contaminants. These functions are especially important for dryer regions like Southern California. However, due to California’s ever-increasing dry conditions, many of the montane meadows are in distress, preventing them from performing these valuable services. For my research, I explored how drought affects the ecosystems of montane meadows. I compared the water table depth to concentrations of Phosphate, Nitrate, and Ammonia to determine if excessive levels were present. I tested the water for Phosphate, Nitrate, and Ammonia to examine their influences, specifically on Bluff Lake, Lodgepole Meadow, and Bluff Meadow in Big Bear. Bluff Meadow shows elevated levels of phosphate, nitrate and ammonia, while Lodgepole shows lowers concentrations in all three nutrients. It is evident that Lodgepole Meadow is rebounding from the drought because it is saturated and productive while, regrettably, Bluff Meadow is still in a state of decline.
