During the project a series of studies was
performed at Maludam National Park, includ-
ing remote sensing, structural and taxonomic
vegetation assessment, litter trap analysis, a
study on non-timber forest products and a bio-
diversity assessment. Before its establishment
in the year 2000, Maludam National Park has
been subject to various degrees of logging from
the 1960s onwards. The park is divided in two by
the Maludam river. At the north-eastern side of
the river (Maludam area) logging was in general
more heavy than at the Southern side of the
river (Triso area). Also, in time logging methods
have changed gradually (minimum felling diam-
eter, desirable species, girdling etc.). The main
