2011 | SPB Rapidly Expands
![Page 10: southernpinebeetle.nj](https://reader036.vdocuments.site/reader036/viewer/2022062520/56815ddf550346895dcc06be/html5/thumbnails/10.jpg)
SPB Impact | Quick tree loss
• Trees may show signs within days of attack
• Pines die as quickly as 3-4 weeks after initial attack

SPB Impact | Canopy Loss• Changes forest type
• Decreases wildlife habitat
• Reduces recreation and aesthetic quality
• Increases stream temperatures and sediment buildup

SPB Impact | Hazard Trees
•Dead pines are highly susceptible to rot fungi
•Branches and tops readily break
•Poses a danger to people and property
![Page 13: southernpinebeetle.nj](https://reader036.vdocuments.site/reader036/viewer/2022062520/56815ddf550346895dcc06be/html5/thumbnails/13.jpg)
SPB Impact | Wildfire Risk
•Dead trees are standing fuel
•Falling needles increase ladder fuels
•Forest floor dries faster without canopy cover

SPB Impact | Blue Stain Fungi• Beetles transmit fungus
• Fungus establishes in days
• Wood’s value decreases

SPB Lifecycle• 4-6 weeks to mature
• Multiple generations per year in the same area
• Larval stage feeds on tree’s inner bark
• Galleries girdle tree

Expanding SPB Infestation
• Generally expands in one direction• May fly and start new hotspot in adjacent forest
![Page 26: southernpinebeetle.nj](https://reader036.vdocuments.site/reader036/viewer/2022062520/56815ddf550346895dcc06be/html5/thumbnails/26.jpg)

Cut-and-Leave Suppression
• Disorients beetles and disrupts population growth• Found successful in prior suppression efforts
across the US and Central America
![Page 28: southernpinebeetle.nj](https://reader036.vdocuments.site/reader036/viewer/2022062520/56815ddf550346895dcc06be/html5/thumbnails/28.jpg)
Cut-and-Salvage Suppression
• Decreases fire hazard• Disrupts all life stages• Preferred method

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
![Page 32: southernpinebeetle.nj](https://reader036.vdocuments.site/reader036/viewer/2022062520/56815ddf550346895dcc06be/html5/thumbnails/32.jpg)
NJFS | Managing Other Lands• NJFS communicates with
Municipal liaison
• Municipality notifies private landowners
• Municipal grants available for management and restoration

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

What you can doto 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
