Abstract

Invasive species represent a critical issue for society. Recent estimates show that such species cost the United States nearly $120 billion per year and put significant pressure on about 42% of threatened and endangered species (Pimentel, D., R. Zuniga, and D. Morrison. 2005. Update on the environmental and economic costs associated with alien-invasive species in the United States. Ecological Economics 52: 273–288). The costs and problems associated with invasive species impact almost all aspects of our society, including agriculture, horticulture, aquaculture, fishing, boating, diving, the environment, and natural habitats.

Management of invasive species is increasing around the world. In the United States, management falls to multiple agencies with complex, overlapping, and confusing responsibilities. However, common threads run through strategic plans at the national, regional, and state levels. Threads include:

  • leadership, coordination, and cooperation

  • research and information management

  • prevention

  • early detection and rapid response

  • effective management

  • education and outreach

Management agencies agree that success in dealing with invasive species relies on education and outreach. This document, an Activity in an Invasive Species Curriculum, helps fill this need by illustrating the use and value of dichotomous keys. It represents one of the dozen activities for middle school use. A copy of the full curriculum is available at: http://edis.ifas.ufl.edu/pdffiles/FA/FA13100.pdf

This Activity addresses the following Sunshine State Standards and Florida Comprehensive Assessment Test (FCAT) benchmarks for grades 6–8:

SC.D.1.3.3 CS

SC.D.1.3.4 AA

SC.F.1.3.1 AA

SC.F.1.3.7 CS

SC.F.2.3.3 CS

SC.G.1.3.2 CS

SC.G.1.3.4 AA

AA = annually assessed

CS = content sampled
