In this Alaska Phenology study an answer to the questions "Can moisture content of Alaska Paper Birch (Betula neoalaskana) buds be used to predict when buds will burst? Does weather and temperature dictate budburst?" is sought. Buds are collected and weighed immediately after collection and after forty eight hours of being in a drying oven. The weight of the wet and dried buds allows for a calculation of moisture content. Using a weather station, access to temperature and cloud and cover readings weather is monitored. Using these variables of moisture content and weather and temperature a prediction is made on the budburst date (budburst being defined as the emergence of tiny leaves from buds on 3 locations on the tree).
