In this study, we simulated the local extinction of a hummingbird-pollinated understory plant, Heliconia tortuosa, from tropical forest fragments using a replicated Before-After-Control-Impact (BACI) experimental design while quantifying plant-hummingbird interactions through two parallel techniques: pollen collected from individual hummingbirds (‘pollen networks’, created from >300 pollen samples) and observations of hummingbirds visiting focal plants (‘camera networks’, created from >19,000 observation hours). Each response variable was measured during each experimental period (pre and post) in sites with and without H. tortuosa removal (treatment and control).

These datasets were collected in the landscape surrounding the Las Cruces Biological Research Station in southern Costa Rica (2016–2018).

Details for each dataset are provided in the README file.
