Flowering phenology informs us about a plant's health and has implications for restoration and biodiversity. In addition, flowering phenology is a valuable indicator of resource availability for fauna and migratory organisms. Remote sensing allows us to move from the flower to broader spatial scales, however, unique challenges arise that require a diverse set of methods, sensors, and products (e.g. the eye of a citizen scientist, Phenocam, drones, satellites). We welcome submissions from researchers who leverage and translate remotely sensed metrics across spatial and temporal scales and existing data networks to capture floral resources for broad applications in the fields of agriculture, remote sensing, macrosystems ecology, and phenology. In particular, we are interested in research that addresses these questions: Can we detect flowering directly and at what scales? What are appropriate surrogates for flowering (e.g. climate, greenness)? How do geography and/or land cover type influence our ability to remotely sense flowering?
