Addressing Purple Loosestrife Management in Rhode Island

Abstract

Global biological diversity has come under increasing pressure from the spread of invasive alien species. Unchecked spread of non-native species often results in habitat degradation and can decimate populations of rare and endemic species. The shortcomings of an exotic species control program that fails to integrate ecology and policy is illustrated through our examination of a non-indigenous plant species, purple loosestrife (Lythrum salicaria L.), in Rhode Island. Our study addresses the efficacy of Rhode Island's current control program for this weedy invader and recommends changes, including the adoption of a noxious weed law.
