Sites within the area are not prioritized, but are managed based on the willingness of the property owner. Property owners can do the work themselves or hire students from the program. Properties that have had students working on them in past years are prioritized to receive help because the best control is achieved with repeated removal. For new properties, if treatment is not possible in the current year, every effort is made to work on the property the next year. Adult volunteers also offer to help cut off the inflorescences (flowers) in the current year to prevent spread of the seeds.
