Fireweed Control: An Adaptive Management Approach

Abstract

Established in the early 1980s, this weed has become widespread on Maui and Hawaii. Pyrrolizidine alkaloid poisoning of animals results from its consumption. Analysis of alkaloid components in weed samples is given. Weed management techniques and their uses and limitations are reviewed. Adaptive management, a cycle of steps or events that facilitates planning, implementation of actions, monitoring of outcomes, and making adjustments to changing situations, is described.
