FORESTS
  • Forests cover almost one-third of the earth's
    land surface the global area of forest systems
    has been reduced by one half over the past three
    centuries
  • Worldwide, the total forest area in 2005 is just
    under 4 billion hectares the rate of
    deforestation is about 13 million hectares per
    year. The net change in forest area in the
    period 2000-2005 is estimated at -7.3 million
    hectares/year
  • Tropical forests are home to about 50 of all
    plant and animal species on the planet
  • Approximately 1.5 billion tonnes of wood is
    harvested for fuel annually worldwide
  • Forests are among the most notable storehouses
    of biological diversity on the land - they house
    over two-thirds of known terrestrial species
    they also harbour the largest share of threatened
    species

Deforestation in Tai National ParkCôte dIvoire
These images show deforestation rates in the
area, believed to be one of the highest in the
world
  • 1988 Shows destruction of small forest fragments
  • 2002 The lighter green strip bisecting the
    images is the result of extensive deforestation
    and intensive cultivation

8
Steady deforestation of dense forest cover in
Kisangani, Congo
  • 1975 The city and surrounding areas are clearly
    visible
  • 2001 The cleared area around the city has grown
    and become consolidated, spreading along rivers
    and roads

9
Changes in narrow coastal plain of Itampolo
Madagascar
  • 1973 Shows heavily forested area, home to
    unique and rare plant and animal species
  • 2001 The burning of forest to clear land for
    dry rice cultivation has led to disappearance of
    forest area (seen as tan)

10
Impact of logging in British ColumbiaCanada
  • 1975-1999 Shows the impact of logging on
    reasonably pristine landscape

11
Forests along Gaspe PeninsulaCanada
The changes in the forest due to logging between
1993 and 2000
12
Angangueo an important habitat for monarch
butterflies, Mexico
  • 1986 Images show degradation of forest area
  • 2001 Between 1984 and 1999, 38 of forests were
    degraded

13
Different land use practices visible across
country border, Mexico/Guatemala
  • 1974 - 2000 Conversion of forest to agriculture
  • Now country border can be seen even from space

14
Disappearing temperate forests of Olympic
Peninsula, United States
  • 1974 Shows patchwork of purple and pink,
    indicating clear-cutting
  • 2000 Evidence of good re-growth of trees in
    forest reserve areas

15
Dramatic tree loss in Washington D.C.United
States
  • Satellite images showing the dramatic loss of
    trees in the District moved Mrs. Casey to action
  • Casey Trees Endowment Fund was created to
    restore the tree cover of the District of Columbia

16
Conversion of forests into palm plantations in
Papua, Indonesia
  • 1990 a new human presence, earth colored roads
    provide access to the forest
  • 2000 rectilinear patterns cover 10,000 ha
  • 2002 Cleared area nearly doubles since 2000

17
Forest in the Demilitarized Zone (DMZ)Korea
Images reveal significant burn scars in the DMZ
18
Deforestation in Oudomxay, Laos
  • 1975 Image shows continuous forest cover
  • 2000 Forest cover dotted with cleared patches

19
Disturbances in forest cover in ArkhangelskRussia
  • In some places, large sections of the forest
    have been clear-felled
  • Other places show a block pattern, where
    sections of relatively undisturbed forest are
    left between clear-felled sections

20
Boreal forests of Sakhalin, Russia
Area burned due to forest fire in Boreal region
21
Exploited Lappi forests in Finland
Images show results of logging in the
northeastern areas of the country
The patches of tan in the 2002 image signify
clearcut areas
22
Iguazú home to endangered rain forestsArgentina
  • 1973 Forest cover is extensive throughout the
    region
  • 2003 Extensive deforestation in Paraguay

23
Converting forests to farmlands in RondôniaBrazil
  • 1975 -Healthy natural vegetation
  • 1989 - Fishbone pattern on the landscape
    indicates agriculture fields
  • 2001 - Agriculture continues to replace forest
    cover

24
Regular monitoring of Amazon rainforests
Almost one fifth of the Amazon rainforest has
been cleared. Between August 2003 and August 2004
alone, 26, 000 square km were cleared 6 higher
than the previous 12 months
Deforestation was worst in the state of Mato
Grosso
25
Indigenous vs. exotic forests in Valdivian,
Chile
Small scale logging of native forests, livestock
and agriculture have been replaced by large scale
timber production
  • 1975-2001 Show changes in land use during the
    last 30 years
