Invasive Species Phenology (IMSA SIR 2017)

Invasive and native forbs and shrubs were identified by Rollinson, Lie, and Dhyani, and Duckett in the King’s Grove area of the Hidden Lake Forest Preserve. Monitoring is primarily conducted by Liu and Dhyani. Forbs include invasive garlic mustard (Alliaria petiolata), geum, and ___. Shrubs include invasive buckthorn (Rhamnus cathartica), invasive honeysuckle (genus Lonicera), and black raspberry (Genus Rubus). Forb traits monitored include initial growth, leaves, flowers/flower buds, open flowers, fruits, ripe fruits, and recent fruit/seed drop. Shrub traits monitored include bud burst, leaves, leaf size, leaf color, leaf fall, flowers/flower buds, open flowers, pollen release, fruits, ripe fruits, and fruit/seed drop. Both forb and shrub monitoring follow National Phenology Network Protocols.
