Status of the World’s Protected Areas
• < 10% of terrestrial ecosystems
• < 10% of the world’s lakes
• 0.5% of marine areas

Atlantic Rainforest Restoration
• The Atlantic rainforest
once covered 400,000
square miles
• Only 7% remains
• 450 tree species per
hectare
• 2.7% of world’s plant
species just in what is
left
• Testing innovative
funding mechanisms
 U.S. companies paying
for carbon sequestration
• How do we restore it?
National Forest System Lands
Critical Roles for the Matrix
1. Supporting populations of species
2. Regulating the movement of
organisms
3. Buffering sensitive areas and
reserves
4. Maintaining the integrity of
aquatic ecosystems
Matrix Management
Principles
1. Maintenance of connectivity
2. Maintenance of landscape heterogeneity
3. Maintenance of stand complexity
4. Maintenance of intact aquatic ecosystems
5. Risk-spreading
Late-Successional

Red-Cockaded
Woodpecker
(Picoides borealis )
• Population declines due to loss
of habitat
• Requires mature (70-100 year
old) long-leaf pine forests for
nesting
• Requires open-canopied, singlelayered structure maintained by
low intensity fire
• Forestry practices now the
leading problem:
• Short-rotation silviculture
• Fire suppression
Historical Range of the Red-cockaded Woodpecker
• Historic: 74-92 millions acres of longleaf pine
ecosystems on coastal plains of the southeast
• Current: 3 million acres remaining

International Paper Habitat Conservation Plan for
Southlands Experimental Forest in Bainbridge, Georgia
1. Requires conservation of 1,500 acres of suitable
nesting habitat
2. Increase this to 5,000 acres
3. Goal of 25-30 nesting clusters
What forestry practices should private companies
and government agencies follow?
-> Conclusion: Maximizing NPV results in a net
reduction of suitable habitat. Moderate NPV
scenarios provide sufficient habitat
Former International Paper Lands: 172,000 acres
“Conserved” Lands in
Northeastern Vermont
Apply the Triad Model: Where are the
reserves? Which of these qualify?
