Decrease in forests and era of wood industries in Indoensia

In 19th century, most of Indonesian land, i.e., 193.7 million ha was covered by forests (MacKinnon 1997)
In 1950, 163 million ha (84%) of Indonesian land was still covered by primary and secondary forests; tea, coffee, and rubber plantations (Indonesia Forest Agency 1950)

Era of pulp-paper industries since 1987

In 1985, forest area was 119 million ha or decreased by 27% from 1950; covering 63% of land (RePPProT 1990)

Collapse of Plywood Wood Industries since 1998
(1) economic crisis in 1997, fall-off of IDR exchange rate, investor debts,
(2) decreasing of wood raw material supply, increasing of wood raw material price,
(3) decreasing of forest potency, infraction of forest management by Forest Concessions,
(4) eco-labelling regulation, illegal exploitation and export,
(5) development of Oil Palm Industries.
Development of forest plantation since 1990
Acacia mangium (Mangium)
Paraserianthes falcataria (Sengon)
Tactona grandis (Teak)

In 1997, forest area was 100 million ha or decreased by 17% from 1985; covering 50% of land
In the early 20th century, forest area was estimated 98 million ha (Wasson & Applegate 2000)
