title: MeadoWatch: a long-term community-science database of wildflower phenology in Mount Rainier National Park

description: We present a long-term and high-resolution phenological dataset from 17
 wildflower species collected in Mt. Rainier National Park, as part of the
 MeadoWatch (MW) community science project. Since 2013, 500+ unique
 volunteers and scientists have gathered data on the timing of four key
 reproductive phenophases (budding, flowering, fruiting, and seeding) in 28
 plots over two elevational gradients alongside popular park trails.
 Trained volunteers (87.2%) and UW scientists (12.8%) collected data 3-9
 times/week during the growing season, using a standardized method.
 Taxonomic assessments were highly consistent between scientists and
 volunteers, with high accuracy and specificity across phenophases and
 species. Sensitivity, on the other hand, was lower than accuracy and
 specificity, suggesting that a few species might be challenging to
 reliably identify in community-science projects. Up to date, the MW
 database includes 42,000+ individual phenological observations from 17
 species, between 2013 and 2019. However, MW is a living dataset that will
 be updated through continued contributions by volunteers, and made
 available for its use by the wider ecological community.
