The opening chapters provide a brief overview of current debates involving invasives, an overview of how invasives are changing their ecosystems, followed by a discussion of manual, chemical, and biological control methods. A helpful chart on herbicides covers mode of action, targeted plant types, and persistence in soil and groundwater.
The heart of the book is the coverage of each invasive plant. Each listing covers identifying characteristics, habitat and range, how it came to North America, what it does in the ecosystem, suggestions for management, and sources for further information. Color photos for each listing show overall form along with closeups of leaves, blossoms, and fruit/seedpods. |
