Sedgwick Reserve

08 Jun, 10 AM - 10 Jun, 05 AM

My research project involves testing the effects of dry deposition of nitric acid and of ozone, two common urban pollutants in the arid west, on several species of lichens. The purpose of this work is to further our understanding of the loss of lichen species diversity in relation to current air quality conditions, and to increase the effectiveness of the use of lichens as biomonitors of air quality. I will be collecting specimens of Ramalina menziesii, a lichen that is very abundant at the Sedgwick Reserve. I will collect approximately 90 to 100 individuals for the summer season of 2007. I may also, depending on the ability of the staff at Sedgwick to cooperate, transplant several individuals in situ as controls. The lichens will be collected from the western ridge of the reserve, and no more than 5 individuals will be removed from each tree. Trees in the area often have 100 or more individuals each, and my collection will have a very small impact on the population. No manipulation aside from possible local transplants will take place at Sedgwick, and no new species will be brought to the reserve.
