Introduction
 Teak (Tectona grandis) is one of important exooted forest
tree species in Indonesia,
 This species is growth naturally in India, South Asia. Then
spreaded-out to South East Asia, Latin America and some
regions in Africa and Australia countries.
 In Indonesia teak has been developed in operational scale
in the areas of Perhutani State Owned Company and in
the form of community forestry both for Java and out side
Java
 The need of wood has been 8.226.000 m3/year, it demands
still supplied from natural forest, while the wood supply
both from Perum Perhutani and community forest only
about 2.757.000 m3 (33.5 %).
 The community forest is needed to be improved due to the
bad stem form, coarse brancing, and taper growth.

Late pruning
The solution is :
Intensive and proper silvicultural
methods should be implemented in
producing the prospective
(productive, effecient, effective,
healthy and sustainable) community
teak forest in Indonesia.
What is a prospective forest?
Prospective forest :
~ Productive
~ High quality of product
~ Effective and efficient
~ Give more benefit for
rural development
~ solve the imployment
problem
What a heathty forest is?
Healhty forest : Forest has capasity to do its
functions optimally
WHAT IS SUSTAINABLE FOREST ?

Conclusion
 Good genetic materials as seed sources
should be available for CF
 Intensive and proper silvicultural methods
should be implemented in CF
 High income of CF can be increased by by
improving wood quality and quantity of CF
wood supply
