1 Future Forests Why it is so important to address the productivity and sustainability of our forests Hal Salwasser College of Forestry Oregon State University January 24, 2002
2
2 Forests cover a large area of the world’s land Source: FAO 2001; USFS 2000
3
3 Forests ~ 45% of the area of Oregon
4
4 Forests ecosystems are vital for life Forests are vital for life Headwaters of the nation: 1/3 area; 2/3 runoff; groundwater recharge; best water from any land use (USFS)
5
5 Forests sustain biodiversity and wildlife habitats
6
6 Forests supply wood: the “green” material Wood products use less energy and water EnergyWater Steel and wood compared in construction of a 10’ x 100’ wall
7
7 Wood products meet essential needs
8
8 Forests store carbon Forests store ~ 45% of the carbon in terrestrial ecosystems Source: IPCC 2000
9
9 Forests sustain livelihoods, communities, recreation, cultural heritage and diversity
10
10 Smaller global forest must serve more people in more ways Wood use up 40% since 1960: 1.5 bcm 2000 Wood use to rise < 50% by 2050: 2 - 2.5 bcm Demand for all forest benefits growing as well Water Biodiversity conservation Carbon stores Recreation, subsistence, cultural uses < 50% of global fiber from planted forests by mid century or earlier
11
11 Forest sustainability rests in a global context 30% + of industrial wood use crosses an international boundary US imports 35% + of lumber used Forest industries integrating globally Carbon, wood, biodiversity are global issues ~ 33% OSU forestry grad students are not US citizens US forest policy choices impact world’s forests
12
12 Forests are managed for many different purposes
13
13 The broad spectrum of sustainable forestry Sustainable forest management varies by diverse forest types It treats each forest differently: depends on goals, capabilities, and needs: A.High yield wood and fiber production B.Multiple values/uses integrated C.Nature preservation, reserves D.Urban forests
14
14 Global Forests 2000 - 2050 ~ 3.9 bil ha: ~ 95% natural; ~ 5% planted ~ 2 cm/ha/yr wood yield from natural forests 5 - 50 cm/ha/yr yield possible in planted forests Intensive forestry on 10% of total < 50% of industrial wood demand Integrated, multi-use forestry on 40% < 50% of industrial wood demand Nature preservation for 50% of world’s forests Source: Victor and Ausubel 2000
15
15 A. High yield forestry Goal: Most efficient wood/fiber production from ~ 10% of world’s forests Increase wood yield: 2X to 5X over natural Increase wood yield: 2X to 5X over natural Reduce environmental impact Reduce environmental impact Improve product quality Improve product quality High return on investment High return on investment Much of world’s wood will come from this forest use
16
16 B. Multi-value forestry Goal: Meet various landowner objectives on ~ 40% of world’s forests Optimize joint production Optimize joint production Sustain desired diversity of environmental, economic, community conditions and results Sustain desired diversity of environmental, economic, community conditions and results Most of the world’s accessible forest will be in integrated management
17
17 C. Nature forestry Goal: Perpetuate native ecosystems, species, nature’s processes on ~ 50% of world’s forests Manage people to reduce impacts Manage people to reduce impacts Manage forests to restore “naturalness” Manage forests to restore “naturalness” Manage ecosystems to ameliorate invasive species, pollution Manage ecosystems to ameliorate invasive species, pollution Parks, reserves, and wilderness for natural values
18
18 D. Urban forestry Goals: Pleasant neighborhoods Resource conservation Property value Safety Wildlife habitats
19
19 Sustainable Forest Management High Yield Multi value Nature Urban Integrate at landscape, regional scales

20 What will this mean for Oregon? Industrial forest roles: ~ 5.8 mil ac; 21% Family forest roles: ~ 4.6 mil ac; 16% State forest roles: ~ 0.9 mil ac; 3% Tribal & County forest roles: ~ 0.5 mil ac; 2% Federal forest roles: ~ 16 mil ac; 57% Depends on policy choices, plans at federal, state, tribal and private levels

23 We face many challenges Meet the needs of growing populations Increase productivity and efficiency Sustain economic vitality of communities Develop innovative policies -- incentives Understand the trade-offs in all choices Invest in new knowledge and technologies Protect water, fish, wildlife, renewal processes Create common ground on sustainability
24
24 Extreme ideologies are not constructive Markets know best Nature knows best Government knows best Scientists know best I know best Locals know best The law is clear CommonGround
25
25 Collaboration and respect are constructive Common Ground Markets are means Learn, work with nature Governments set standards Science informs choices Everyone has ideas Locals know a lot Laws give direction
26
26 Let’s consider our choices Managing forests and forest uses on a path to productivity and sustainability: who, how, where, when?
