This is the full sampling protocol for a long-term native bee biodiversity monitoring/survey/inventory set up in 2011 at Pinnacles National Park in California. The park was sampled using these methods in 2011, 2012, and may be sampled again using the same methods in 2019 and 2020 to add an important additional time-step to earlier sampling to aid determination of trends in native bee ecology/decline/status over time.More details about the 2011-2012 work can be found in the following masters thesis:Meiners JM. Biodiversity, Community Dynamics, and Novel Foraging Behaviors of a Rich Native Bee Fauna across Habitats at Pinnacles National Park, California. Masters of Science, Utah State University. 2016. These methods are also develped from a similar protocol that can be found at: LeBuhn G, Griswold T, Minckley R, Droege S, Roulston T, Cane J, et al.
