Southern Pine Beetle (SPB) is the most economically important forest pest in the southern United States, causing an estimated $1.5 billion in damage in recent years. Preferred hosts are shortleaf, loblolly, Virginia, and pitch pines.
These county summary hazard maps help identify areas with potential for experiencing significant SPB activity. The maps are derived from the US Forest Service's 2012 National Insect and Disease Risk Map (2012 NIDRM). NIDRM is a nationwide strategic assessment and database of the potential hazard for tree mortality due to major forest insects and diseases over the 2013-2027 time period.
