Authors’ estimates. Based on FAO (1982, 1990, 1995, 2001); Sips (1997); Wadsworth (1997); WRI-World Bank (2000).
In tropical America, about 38 million ha are classified as secondary forests (second-growth forests). For the other regions
it is not possible to distinguish between degraded primary forests and secondary forests
Extent of degraded forest
Only rough estimates exist, no thresholds
Laestadius and Potapov (2009): More than 1 billion ha
ITTO (2002): about 850 million ha
WRI (2014): 104 million ha (more than 8 percent) of the world’s Intact forest
landscapes (IFLs) have been degraded since 2000
http://www.wri.org/blog/2014/09/8-percent-worlds-remaining-pristine-forests-degraded-2000
WRI (2014): More than two billion hectares worldwide offer opportunities
for restoration an area larger than South America. Most of these lands are in tropical and temperate areas

8. Conservation of Shorea spp Genetic Diversity in
Kalimantan, Indonesia: accelerating natural recovery
• Tengkawang (Shorea spp) has important
role in ecology and economy for indigenous
people but it is threatening due to adverse
environmental condition, unsuccessful
conservation
• Dipterocarps Forest Research Center
implemented ITTO project (PD586/10) on
Tengkawang; established genetic diversity
conservation plots of T. (2 ex-situ plots in E.
Kalimantan, 2 in-situ plots in W. K. & 1 in-situ plot in S. K.)
• Lesson learned: Integrated strategy and
continuity of knowledge transfer of
Tengkawang issue, including its
identification, needs serious commitment
and good cooperation from government
agencies and related stakeholders;
increasing roles of village cooperatives

9. Dipterocarp planting in Indonesia: assisting natural
regeneration-enrichment planting
• Gadjah Mada University implemented ITTO
project [PD41/00]; screened 64 potential
dipterocarp species; selected the three best-
performing Shorea species as the basis for
producing planting materials
• Developed an innovative silvicultural system
and model for planting in logged-over forests
3 m wide strips are cleared in a straight line,
which are separated by 17 m blocks of semi-
natural forests.
The seedlings from the selected best species are
planted in line in the cleared areas at a stocking
rate of 200 stems/ha (thinned to 160 stems/ha)
• Revisit “The Kalimantan Forest Company
Model” incorporating the use of improved
indigenous species for rehabilitation of logged
over forests, integrated pest management and
organic soil nutrient enhancement techniques

over forest, East Kalimantan, Indonesia
10. In Ciamis District: extensive area of degraded forest land
but most is in government land while private forests cover
32,000 ha; no tenure conflicts around private forests; well
developed “tree planting culture”
Forestry Services of Ciamis District with FORDA
implemented ITTO Project (PD 27/04):
• 10 farmers groups for special emphasis in building capacity -
“quality” of seedling production
• Application of silviculture techniques
• Development of a business model – leading to a village as a
SFM unit
Lesson learned:
• Support to motivated local leaders is effective in spreading
knowledge and information to improve productivity of private
forests.
• Improving marketing conditions for forest products from
private forests is a difficult challenge
• An enabling regulatory framework is more effective than an
enforcing one requiring farmers to plant tree seedling and
protect forests

11. Some messages
Production forests with FMU management plans are
key to achieving sustainable forest management - strict
conservation measures (e.g. at least 10% area); social forest allocation;
improved productivity from production forests
Urgency to restore degraded tropical forests with site-
level viable strategy accelerating natural recovery and
assisting natural regeneration – conservation of genetic
resources and production of quality planting materials; long-term local
research programs (good science) and motivated local leaders;
Adaptation to support the restoration and sustainable
management of degraded forest lands - keeping forests
young, weed, pest and fires management, increased vulnerabilities of
forest dependent people, improving marketing forest products
High level of investments in restoration of degraded
forests and forest ecosystem adaptation under the
Paris Agreement
