Standardized methods, such as those from the USA National Phenology Network, provided useful tools for optimizing the timing of management practices moreover, these data may help to better inform management of invasive plant species with regard to restoration efforts at a global scale. encelioides will have a higher chance of succeeding. By incorporating phenology information into invasive plant control operations at Midway Atoll NWR, efforts to eradicate V. Accordingly, invasive plant control schedules were adjusted to re-treat infested areas every 30 days.Ĥ. encelioides to transition from leaves to seed drop, although the time required varied across the year (range: 31–175 days). We found that it took an average of 76 days for V. encelioides plants on Midway Atoll NWR for 12 months beginning in August 2016 we visited these plants every 3–7 days and noted which phenophases the plants exhibited.ģ. To obtain this information, we documented the timing of key reproductive life cycle events in cohorts of V. encelioides on Midway Atoll NWR were challenging, especially when targeted plants went to seed before being treated.Ģ. Little is known about the reproductive phenology of Verbesina encelioides (golden crownbeard), which is a highly invasive annual forb species at Midway Atoll National Wildlife Refuge (NWR). Restoration of degraded lands often depends on knowledge of invasive plant species’ ecology coupled with well-timed treatments to control them.
