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.
