This document summarizes a study comparing the costs of five different methods for controlling the invasive plant species Melaleuca quinquenervia in Florida. 100m2 plots were established in four 40-acre parcels to test different treatment methods. Data was collected on biomass, tree density, and costs. The results showed that aerial spraying (parcel 5) had the lowest cost per hectare treated at $705.80, while mechanical removal and chipping (parcel 2) had the highest biomass removal and tree density reduction but also the highest total cost. Further analysis of regrowth and multi-year costs was recommended to fully evaluate effectiveness of the different control methods.
