Global Demand for WoodConsumption is Growing
• Up 1.6% annually (up 60% by 2030)• 50/50 for domestic/industrial wood
• 80% of consumption is for industrial purposes in developed countries• 80% of consumption is for domestic use in developing countries
• Both uses (domestic and industrial) will continue to be important• 10,000 products made from wood

State of the World’s Forests: Global Deforestation and Degradation
Deforestation 30 to 50% loss of total forest area
in last 8,000 yrs Last 50 years
1.2 ha/person in 1960 0.6 ha/person in 2005
Current annual net deforestation 8 million ha (20 million acres) 2/3 of Florida
Roads lead to access
Degradation High grading of valuable timber Unsustainable harvest levels Poor practices leading to soil
erosion, loss of wildlife habitat, etc.
Settlement in tropical dry rainforest

Forests in Florida
By far, the most important land use:• Half of FL land area is forested• Mostly in N FL• Pastures are distant second (17%)
$16 billion/yr industry (#1 “crop”)$8.0 billion/yr for hunting, fishing and wildlife viewing$1.8 billion/yr in recreation and ecotourism at FL parksPine straw, palmetto, silvopastures Critical ecological services

Forests in Florida:Increasing Demands For All Goods & Services
Population: 16 million people• Fastest-growing state east of MS River• 28 new people per hour (400,000/yr)• 92% live in urban areas, mostly in S FL
Increasing Demands for:• Large quantities of high quality water• Jobs and products• Biomass for energy and fuels• Recreation and other social services• All ecosystem goods and services
![Page 31: Forests of the World: Economic, Social and Environmental Values](https://reader036.vdocuments.mx/reader036/viewer/2022070501/56816912550346895de02d97/html5/thumbnails/31.jpg)
Forests in Florida: Urbanization!
Decreasing Forest Land Area• Losing 40,000 acres per year (mostly to urbanization)
1960: 4 acres of forests per person 2000: 1 acre of forests per person
![Page 32: Forests of the World: Economic, Social and Environmental Values](https://reader036.vdocuments.mx/reader036/viewer/2022070501/56816912550346895de02d97/html5/thumbnails/32.jpg)
Forests in Florida: Urbanization!
Increasing Fragmentation of Rural Forests• Increasing WUI (1 out of 5 acres in FL in WUI)• Impacting wildlife and bird populations• Increasing role of fire• Impacts of rural development
Increasing Role of Urban Forests• Microclimate amelioration• Stormwater runoff• Recreation• Aesthetics• Psychological benefits
![Page 33: Forests of the World: Economic, Social and Environmental Values](https://reader036.vdocuments.mx/reader036/viewer/2022070501/56816912550346895de02d97/html5/thumbnails/33.jpg)
Forests in Florida:Production and Protection
Production Forestry• Meet demands from fewer acres (timber, fiber, NTP, energy)• Increase production efficiency of plantations• All in sustainable manner (BMPs, certification, etc)
Conservation Programs• State buying 2 million acres (1/8 of all forest land) + easements• FL already owns more forest land than any other state in south• Manifests desire of citizens to support conservation
![Page 34: Forests of the World: Economic, Social and Environmental Values](https://reader036.vdocuments.mx/reader036/viewer/2022070501/56816912550346895de02d97/html5/thumbnails/34.jpg)
Conclusions:Forests are Important in this World!
All types of forestsNative forests, plantations, agroforests, urban forests
All forest productsTimber, paper, medicinals, recreation, hunting, homes
All forest practicesPreservation, conservation, production, multiple use
All forest usesReserves, family forests, industrial timberlands, city parks, etc.
All forest valuesSocial values (recreation, water & soil quality, homes for people)Economic values (products, jobs, direct and indirect impact)Environmental values (C sequestration, habitats, biodiversity)
