2011 | SPB Rapidly Expands
SPB Impact | Quick tree loss Trees may show signs within days of attack Pines die as quickly as 3-4 weeks after initial attack Gerald J. Lenhard, Louisiana State University, Bugwood.org
SPB Impact | Canopy Loss Changes forest type Decreases wildlife habitat Reduces recreation and aesthetic quality Increases stream temperatures and sediment buildup Pine warbler Ollie Knott, Georgia Forestry Commission, Bugwood.org
SPB Impact | Hazard Trees Dead pines are highly susceptible to rot fungi Branches and tops readily break Poses a danger to people and property
SPB Impact | Wildfire Risk Dead trees are standing fuel Falling needles increase ladder fuels Forest floor dries faster without canopy cover Ronald Billings, Texas Forest Service, Bugwood.org
SPB Impact | Blue Stain Fungi Beetles transmit fungus Fungus establishes in days Woods value decreases Erich Vallery, USDA Forest Service, Bugwood.org
SPB Lifecycle 4-6 weeks to mature Multiple generations per year in the same area Larval stage feeds on trees inner bark Galleries girdle tree Richard Kliefoth, Boyce Thompson Institute
SPB Signs | Stage 3 - Vacated Exit Holes Red crown or no foliage Clerid larvae or pupae Loose bark, blue stain Ambrosia beetle dust Erich G. Vallery Ron BillingsG. Keith Douce State Forestry Services
SPB Signs | Stage 2 – Brood Trees Green crowns fade to yellow Hardened pitch tubes Galleries with larvae or pupae New adults Erich G. Vallery Gerald J. Lenhard Louisiana State University Erich G. Vallery
SPB Signs | Stage 1 – Fresh attacks Fresh pitch tubes Adult clerids on bark Green crown Boring dust in bark crevices Erich G. Vallery Ron BillingsCleridae, Wikipedia

SPB Spot Growth
SPB Triangle for Spot Growth Ronald F. Billings, Texas Forest Service
Expanding SPB Infestation Generally expands in one direction May fly and start new hotspot in adjacent forest
Effects of SPB Spot Disruption Ronald F. Billings, Texas Forest Service
Cut-and-Leave Suppression Disorients beetles and disrupts population growth Found successful in prior suppression efforts across the US and Central America
Cut-and-Salvage Suppression Decreases fire hazard Disrupts all life stages Preferred method
Successful Suppression | Winslow WMA
NJFS | SPB Monitoring Monitors SPB and clerid populations 18 Traps Baited with pheromones and turpentine Contents sent to US Forest Service Ronald F. Billings, Texas Forest Service, Bugwood.org
NJFS | Managing DEP Lands Survey - aerial flights Map data and determine ownership Verify state lands spots on ground Mark area for cutting Cut within a week Monitor after treatment via air and ground
NJFS | Managing Other Lands NJFS communicates with Municipal liaison Municipality notifies private landowners Municipal grants available for management and restoration Ollie Knott, Georgia Forestry Commission, Bugwood.org
Detect SPB DEP Property Determine Property Ownership Prioritize Ground Truthing Non-DEP Property Confirm SPB Municipal Notification Ground Truth and Flag Suppression Area Perform Suppression Action Monitor and Report Large Infestation Consulting Forester CTE or Arborist Small Infestation Encourage Suppression Other State Agency Notification Confirm SPB Perform Suppression Action Monitor and Report Ground Truth and Flag Suppression Area NJFS | SPB Process
Landowners | Protect Individual Trees Safeguard high-value trees Treat trees with spray or injection Protect a tree for 3 months to 2 years depending on treatment Contact a licensed pesticide applicator *Only effective prior to an attack Emamectin benzoate (TREE-age) Arborjet

What you can do to minimize SPB impact Recognize telltale SPB signs Act quickly before SPB spreads Perform suppression Salvage and sell or utilize Restore Treat high value trees Thin your forest 2/3 of New Jersey forests are privately owned
