Forest and Bird Weed Guide 2021
How To Use This Guide
The weeds are listed in alphabetical order
within categories: trees, shrubs, climbers,
palms, and ground covers. Indicated for
each weed are codes for adverse effects
and options for organic and herbicide
control. The codes are explained in the
key on page 2. Some of these weeds are
really difficult to kill so repeated effort
may be required.
