Despite the importance of plant-pollinator interactions for ecological communities, few long-term observational studies have been conducted of plant-pollinator networks. This study involves the annual collection of plant-pollinator interaction data from up to 18 meadows in the Willamette National Forest, Oregon, including 12 meadows in the HJ Andrews Forest. This study addresses how meadow size, the amount of nearby meadow habitat, weather, degree days, and soil moisture are related to the flowering of meadow plants and the frequency of plant-pollinator interactions.

To quantify and describe the diversity and abundance of flowering plants and their visitors in montane meadows of the HJ Andrews Forest. These data enable detection of long-term trends in pollination, their relationships with climate and vegetation change, and spatial patterns of plant-pollinator interactions.
