WILDLIFE CONSERVATION

An integral part of the forests is its fauna resources.  Wildlife resources in Deramakot Forest Reserve (DFR) have received little attention in the past, as the primary objective was timber management.  Timber production will remain the dominant factor in planning land use in DFR.  But as of late, and in having to meet the requirements under Principle # 9 (identification of High Conservation Value Forest) of the FSC’s Principle and Criteria to ensure continued certification, a simple, practical guide to monitor and document wildlife resources and their habitat in DFR, has been developed by Dr. Isabelle Lackman-Ancrenaz and Marc Ancrenaz (1999).  It was not until the year 2001 that this system was put into use.

DID YOU KNOW?  DFR is a key habitat for five globally threatened large mammals, namely the Orangutan, Pygmy Elephant, Tembadau (Banteng), Proboscis Monkey and the Clouded Leopard.

Five monitoring components are currently being carried out in DFR.  These are:

i. Riverside (four times a year);
ii. Salt Lick (once a month);
iii. Orangutan aerial nest count (twice a year);
iv. Elephant (once a month); and
v. Opportunistic Sightings (daily).

1.0  Salt Licks

Four natural salt licks in DFR were identified with the assistance of Dr. Hisashi Matsubayashi, a mammalogist from the University of Tokyo, Japan. Natural salt lick is one attribute to High Conservation Value Forest.

Water and soil samples have been collected for analysis and were found to contain high amounts of Ca, Mg, Na and K.  Other ocular findings in relation to these salt licks are shown in Table 1.

2.0   Orangutans

Orangutans (Pongo pygmaeus) are exceptionally shy animals, which contribute to the fact that their population and distribution cannot be readily assessed by direct sightings.  The aerial census methodology by counting Orangutan nests along pre-determined transects, is being used in DFR.  This exercise is carried out twice a year and the results are shown in Table 2.

Table 2.       Orangutan density.

It is estimated that a minimum of 900 Orangutans are currently residing in DFR. The recent survey indicates that there are more nest building activities in the central and eastern part as compared to the west of DFR.  The focus of the various forest management activities (harvesting, rehabilitation and silviculture tending) that are now currently concentrated in the west, could be the reason for this.

3.0       Opportunistic Sightings

Observations are based on daily opportunistic encounters and calls.  Refer to Table 3. Opportunistic sightings (1997 – 2003).

4.0  Mitigating the impacts of Forest Management Activities on Wildlife

As planned in the FMP, approximately three quarters of DFR remains undisturbed or closed to forest management activities at any given time.  This means all forest management activities (silviculture, enrichment planting and harvesting) is focused on a small portion (10,000 ha) of DFR staggered over a period of ten years, which translates to a management cycle of about 40 years.  This is planned primarily to encourage plant succession without disturbance, and at the same time they act as a sanctuary for wildlife that thrives in DFR.

Wildlife and their habitat contiguity is ensured simply because DFR is a well managed forest and hopefully, it will stay that way in perpetuity.  Regardless of this, mitigating measures are put in place to minimize the impact of human presence and interference to the eco-system.
