Long-Term Monitoring of Plant Reproduction and General Flowering at Lambir Hills National Park, Borneo

General flowering (GF) is a masting phenomenon found only in Asian dipterocarp forests, involving the synchronized flowering/fruiting of diverse plant groups. GFs have been observed in areas that have relatively weak seasonality in precipitation or temperature and that may experience irregular droughts associated with ENSO. Previous studies have shown that GF is synergistically driven by cool air temperature and drought. GFs have significant impacts on flower visitors, frugivores, forest biomass, tree growth, and plant regeneration. Our data paper presents one of the longest time-series datasets of plant reproductive phenology, including records of large GF in 1996, 2003, 2006, and 2009–2010.
