iNaturalist is a tool that provides many ways for us to learn about the biodiversity around us and to contribute to valuable scientific research and conservation. Yet some organisms tend to be documented frequently while others, such and fungi and invertebrates, are underdocumented. Whether you're new to iNaturalist or want to add an extra goal to your City Nature Challenge adventures this year, join us as we speak with two experts who will give us pointers on how to improve both our iNaturalist observation and ID contributions. Damon Tighe Damon (@damontighe) is a biotech educator in the San Francisco Bay area, was involved on the first draft of the human genome, and fell head over heels for fungi after running out of food on the John Muir Trail where he saw large mushrooms and wondered, "Could I eat that?" He has been a collector for the California Fungal Diversity Survey project and helped many high schools build programs to sequence their local fungi. He’s been using iNaturalist for over a decade while racking up over 100k observations, over 1,000 of which include DNA sequences and rich metadata. He believes passionately in the way community science can change the world with data and change an individual’s orientation to the world around them in fundamental ways. Patricia Simpson Patricia (@patsimpson2000) is a science technician at Cabrillo National Monument. There, she directs plant propagation and habitat restoration efforts. She also conducts community science-based native bee research at the park under the guidance of Dr. Keng-Lou James Hung and Jessica Mullins. The surveys have produced around 9,000 iNaturalist observations of native bees and recorded their plant visitations. The long-term surveys will hopefully shed light on the population trends, phenology, nesting habits, and plant preferences of the native bees that call the park home. Patricia also serves on the board of the California Native Bee Society, which aims to protect California’s native bees by fostering sustainable stewardship through research, education, and conservation.
