Ecosystem restoration concession
(ERC) has the potential to slow
down and reverse degradation and
deforestation in production forests.
ERC mobilizes new resources and
offers an alternative approach to
addressing long standing issues
such as restoration, biodiversity
conservation, forest business
development and forest governance.
.
Mission Hutan Harapan
• Protect and restore the biodiversity,
ecosystem service and production of
Indonesia natural forest.
• Sustainably manage the forest resources
in harmony with nature and people’s
needs.
• Collaborate with diverse partners and
demontrate innovative techniques in
forest restoration.
Recent surveys suggest that over 738 species of trees. which are dominated by
meranti (Shorea spp), medang (Litsea spp) and balam (Palaquium spp. There
are four plant species that are Critically Endangered (the Dipterocarp
trees
Hopea mengerawan, Hopea sangal
and
Shorea acuminata,
and
the smaller
Syzygium ampliflorum
), two Endangered and six are listed
as Vulnerable.
To date, 305 bird species have been recorded at Harapan, including nine
globally threatened species: the Endangered Storm’s Stork and eight
Vulnerable species. In addition, a remarkable 66 Near Threatened
bird species have also been recordedi.
64 mammal species have been recorded including a remarkable five primates
and seven cat species, including up to 20 Sumatran Tigers. Iincludes
Asian Elephant and the Sumatran Tiger that are Critically Endangered,
six Endangered species (Asiatic Wild Dog, Sunda Pangolin, Mitred
Leaf Monkey, Agile Gibbon, Siamang and Malayan Tapir), and other
ten Vulnerable species
At least, 56 species of reptiles including lizards, tortoise, and various kind of
snakes are living in the Harapan
In addition, 38 species of amphibians have been identified in HRF. These frogs
and toads hold the important role as one of the indicators of environment
health.

FOREST INVENTORY (IHMB and
Risalah)
Objectives :
• To establish the timber standing
stock;
• As a basis for a 10 year workplan;
• To monitor trends in the timber
standing stock;
• To understand the structure and
composition of the forest.
Typology A: secondary forest with <40% canopy cover, and can be
categorized as heavily degraded forest. Within this area, scrubs
dominate especially in the ex-burned areas and in areas that are
dominated by sapling size trees (diameter < 10 cm)
Typology B: secondary forest, with canopy cover between 40-70%
and dominate by tree with diameter between 10-20 cm.
Typology C: Secondary forest with complete forest stratifications
from seedling (height between 0.3-1.5 m), saplings (height > 1.5 m
and diameter < 10 cm), poles (diameter between 10-20 cm), and small
trees (diameter >20 cm). The canopy cover is ranged from 71-100%
with average tree diameters > 20 cm.
TYPOLOGY
Number of
species
This Figure the highest number of species (for all tree
categories) are in forest typology A, and there is only a
slight difference in the number of species between
forest typology B and C. In the open area, the number
of species for all categories (saplings, poles, and trees)
are very small because these areas are already been
planted with palm oil trees, or covered by resam
(Dicranopteris linearis), alang-alang
and “
pakis-
pakisan
”.
Number of
species
This figure shows that Lauraceae ((Medang Litsea sp.) is the
common tree family in all forest typologies. The next
common tree families are Euphorbiacea, Fabaceae, and
Dipterocarpacea. The low number of tree species from
Dipterocarpacea family indicates the high forest exploitation
activities in this area when it was still assigned as logging
concession (HPH). This condition also shows that tree
species from Dipterocarpacea family, also known as the
primary forest species, can not regenerate well within the
existing forest condition.
