at intervals from known locations, can be stitched together, to create large-scale to Continent-scale mega transect pictures of the ecosystems. In 2006, Dr. Michael C. McGrann, and his wife Amy M. McGrann, hiked the length of the California section of Pacific Crest National Scenic Trail (PCT) in the western United States from Mexico to the Oregon border (2,736 km) while systematically collecting avian-habitat data on 3,578 survey plots separated by 10-minute hiking intervals. This work was completed in a single field season from 2 April to 8 September. From this data, Dr. McGrann and his collaborators described the elevation and latitudinal distributions of birds along the PCT and statistically modeled avian species richness relationships with elevation, climate, and environmental factors, including temperature, precipitation, and primary productivity. The results from this work show that birds can exhibit heterogeneous relationships to temperature, precipitation, and productivity, depending on the distinct environmental and climate conditions of each of the ecological regions traversed by the PCT. The PCT Mega-transect is an ongoing research project for Dr. McGrann in collaboration with several other researchers. He has continued his biodiversity surveys along sections of the PCT in 2007, 2010, and 2015, and he is working to expand taxa surveyed along the PCT and to involve his undergraduate students at William Jessup University in the PCT Mega-Transect. In 2007-2008 J. Michael Fay and Lindsey Holm completed a 1300 mile Redwood Transect of 333 days. This was a transect that spanned from the southernmost to the northernmost redwood tree in California and Oregon. They walked extensively on private timberland and public land recording data on historical exploitation, current forest stand characteristics, silviculture, and many other aspects of the redwood ecosystem. The results will be published in National Geographic in 2009. The Appalachian Trail Conservancy and the National Park Service are adopting the idea of a mega transect for the Appalachian Trail (A.T.) Like other mega transects, the A.T. MEGA-Transect aims to monitor the natural resources along the trail, understand the status and trends of these resources, and inform and engage the public and stakeholders. The 2,178-mile-long trail crosses 14 states, from Georgia to Maine, and is visited by one to two million people, and completed by about 400 people each year. Volunteer citizen scientists are beginning to implement monitoring protocols to track natural resources such as wildlife presence, water quality, forest health, invasive plants, endangered species, mountain birds, phenology,
