Harmful Invasive Species: Legal Responses describes the law and policy regarding harmful non-indigenous species in six countries: New Zealand, Germany, South Africa, Argentina, Poland, and the U.S. It addresses three international and cross-cutting dimensions of harmful non-indigenous species policy: quarantine systems, trade issues, and the special concerns raised by genetically modified organisms. It is a "must-read" for concerned scientists, lawyers, policy-makers, and citizens, in the U.S. and abroad.
