Early herbicide
Intensive prescribed burns
Less aggressive thin at 40 and 60
No final harvest
All include site preparation and planting ($306)
Longleaf Pine Straw
3 Cases: no pine straw, conservative, moderate
Conservative pine straw
Age 16 until 55 or final harvest
Every 3rd year
$75/acre/year
Moderate pine straw
Frequency and duration unchanged
$150/acre/year
Consistent with literature
Recent sales at Bladen Lake State Park from $150-$300/acre
Rural Alternatives
Loblolly Pine
Traditional
25-year rotation, timber maximizing
Long Rotation
75+ year rotation to provide RCW habitat
No final harvest
Commercial thinning of 20 tons every 20 years
Agriculture
North Carolina average corn and soybean returns

Conclusions
Longleaf Competition with Loblolly
Pine straw essential to make longleaf competitive
Need more research on pine straw markets, price impacts
Post-recession prices have negative impact on loblolly
present values
Multiple products and max timber competitive or better than loblolly
For scenarios creating habitat, longleaf with pine straw provides
more profit
Optimal solution may include managing some areas for multiple
products and others for ecosystem services
Lower risk in diversified longleaf scenario which includes
both pine straw and timber
Pine straw prices have never dropped
Higher risk in establishment, grass stage, ice damage

Longleaf Cost Share
Cost share programs are not yet included
Adding a minimum one time payment of $306 to cover
establishment costs alone greatly reduces opportunity costs
and payments

Longleaf and Agriculture
Forestry cannot compete with average crop returns
in average years on good sites
Lower quality sites more representative of
candidates for this public-private cooperation
Agriculture is highly variable, only used on high
quality sites, high input costs
Annual payment needed to offset difference in SEV is
$191-$552/year/acre on 10-year contract
