Matrix Management FOR 272 – Sustainable Forest Management
Global Deforestation • Deforestation accounts for 20 to 30% of global greenhouse gas emissions FAO (2005): • 13 million hectares deforested annually • Net loss of 7.3 million ha/yr (2000-2005) • Down from 8.9 million ha/yr (1990-2000) • Rates now increasing again due to conversion for oil palm plantations
IUCN’s* Six Protected Areas Management Categories Category I. Strict Nature Reserve: managed for science or wilderness Category II. National Park: managed primarily for ecosystem protection and recreation Category III. Natural Monument: managed primarily for conservation of specific natural features Category IV. Habitat/Species Management Area: managed for conservation through active intervention Category V. Protected Landscape/Seascape: Managed for cultural and scenic integrity, conservation, and recreation; human settlements and agricultural areas are accommodated Category VI. Managed Resource Protected Area: Managed primarily for the sustainable use of ecosystems IUCN = The World Conservation Union, previously known as the International Union for the Conservation of Nature
Status of the World’s Protected Areas • 12% of terrestrial ecosystems • < 10% of the world’s lakes • 0.5% of marine areas Data: World Conservation Monitoring Centre
No more than 10-15% of the world major biomes are likely ever to be protected • 50 % of tropical taxa predicted to go extinct with several decades even if > 10% of tropical forests are protected (Soule and Sanjayan 1998) • Continued bias towards high elevations and least productive soils • Hotspots and representativeness will be key issues • 25 biological hotspots • 1.4 percent of Earth’s land surface • 35 percent of vertebrate species • 44 percent of the world’s plant species. • 1/3 of terrestrial plants and animals confined to less than 2 percent of the Earth’s surface. • Most hotspots have no conservation protection.
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?

Critical Roles for the Matrix • Supporting populations of species • Regulating the movement of organisms • Buffering sensitive areas and reserves • Maintaining the integrity of aquatic ecosystems • Opportunities for timber harvesting and resource extraction
Critical Roles for the Matrix Other ecosystem functions • Hydrologic and watershed processes • Regulation of regional and global climate • Carbon sequestration • Nutrient cycling and soil conservation • Pollination service • Clean air and clean water • Open space, recreation, aesthetics, wilderness/outdoors experiences, quality of life amenities, etc.
Matrix Management Principles • Maintenance of connectivity • Maintenance of landscape heterogeneity • Maintenance of stand complexity • Maintenance of intact aquatic ecosystems • Risk-spreading

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, single-layered 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
Matrix Management Examples for • Red-Cockaded Woodpecker • Federal ESA Recovery Plan Pending • International Paper Habitat Conservation Plan for Southlands Experimental Forest in Bainbridge, Georgia • Requires conservation of 1,500 acres of suitable nesting habitat • Increase this to 5,000 acres • 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
