National Invasive Species Awareness Week
National Invasive Species Awareness Week (NISAW) takes place annually during the last week of February.
The spread of forest pests, diseases and invasive species persistently threatens the health and survival of southern forests. Forest insects account for 20% of the total negative growth impact on forest trees, while diseases account for 45%.
Monitoring, suppression and education are important tools for preventing and managing these pests.
Fact Sheets
PYRUS CALLERYANA
Bradford/Callery Pear
Learn MoreCallery or Bradford pear was introduced to the United States in 1909, and its uniform shape, profuse white
flowers, and bright red fall foliage made the Callery pear a much-planted ornamental throughout the southeast.
LONICERA JAPONICA
Japanese Honeysuckle

CHINESE, EUROPEAN & JAPANESE
Privet
Learn MorePrivet is widely disseminated by many birds and other wildlife species that consume the fruit. Privet is difficult to control as it spreads aggressively
through bird/animal seed dissemination and aggressively colonizes through root and stem sprouts/suckers.
