Bukit Lagong Forest Reserve to be quarried

Proposed Quarry Concessions in Bukit Lagong Forest Reserve

Bukit Lagong Forest Reserve (BLFR) is  ~ 3,700 hectares (this figure does not include FRIM’s 530ha, which is under Federal Land Commissioner title).   This biologically diverse conservation area serves as a water catchment area providing clean water supply for local communities, protects slopes and prevents landslides

Under the National Physical Plan, Bukit Lagong Forest Reserve is ranked as an Environmentally Sensitive Area (ESA) where only low-impact tourism is allowed, but no physical development and agriculture activities are permitted.  The environmentally sensitive areas are clearly mapped in the national physical plan and have been agreed to by both the federal and state governments.  Under the local plan for Selayang, Bukit Lagong Forest Reserve is zoned as a conservation area.

The Forest Research Institute of Malaysia (FRIM), declared a National Heritage in 2012, was nominated as a UNESCO World Heritage Site in 2017. Bukit Lagong FR serves as a buffer.  Allowing quarrying to continue and grow in size might affect FRIM’s chances of achieving the UNESCO World Heritage Site (WHS) status.    It will not be a positive reflection on the Selangor State Government’s commitment to sustainably manage, protect and conserve the state’s permanent forest reserves and proposed World Heritage Sites.

The Selangor state government imposed a 25-year moratorium on logging starting 2010.  Allowing quarrying in forest reserves not only goes against the government’s moratorium on logging, it is also an extremely destructive activity.  How can the state government still call the quarried areas forest reserves?

Development projects in forest reserves will only provide short-term benefits to the Selangor State Government.  Chipping away at our forest reserves is not a sustainable practice. In the long run, it will translate into the continuing overall loss of forests in our state and country, further compromising ecosystem integrity.  Forest conservation in Selangor should be given the highest priority.  By conserving and protecting our forest reserves, the state government and the people will benefit from invaluable long-term social and economic benefits. 

The Selangor state government must cancel the proposed new quarry concessions in Bukit Lagong Forest Reserve and commit to stop quarrying in forest reserves.   Our forest reserves should be conserved and protected.  They are not a resource to be exploited.

Quarrying in Bukit Lagong Forest Reserve

  1. As seen from a forest planning map that was published in edgeprop.my (also refer to Appendix 1 – overview webmap)

~1000 hectares (28%) designated as quarriable, of which:

~200 hectares is being quarried by six (6) existing operators under ‘Minor Licences’ (NFA’84, Part IV Chapter 3) which were apparently repeat-renewed every six months for close to 30 years now, and

~800 hectares ‘allocated’ to named concessionaires but not yet being quarried

  • The six existing quarries (approximately footprint yellow shaded in Appendix 1 map) started up between 1992 and 2002 – well before the 2010 logging moratorium. Four of them are associated with “major corporate names”- YTL, IJM, CIMA, and Hanson(Heidelberg)
  • Post- the 2010 logging moratorium, the output of eight forest quarries (6 in Lagong, 1 in Ulu Gombak, 1 in Sg Lalang) “anchored” Selangor’s forestry income, which grew to its current level of just under 50mil/year with no new quarries being opened.
  • Selangor’s Forest Management Plan (FMP) 2021-2030 proposes to only hold steady the quarrying income at the aforesaid level, through to 2030
  • Exco Hee Loy Sian’s media statement of 29th September asserts that the ‘19’ (but possibly 21) new concessions are a replacement program, in view of the current concessions imminently expiring (from 2023 onwards)

Why is this number of proposed new concessionaires more than triple of the existing operators, if the FMP’s proposition is only to sustain current production level?

  • Eight quarries currently operating in Selangor are located in forest reserves based on information provided during a recent Selangor State Assembly session. Six of these are in Bukit Lagong Forest Reserve (BLFR). This would imply that approximately 75% of Selangor’s forest-derived rock products is coming from a single forest block comprising less than 2% of Selangor’s forest reserves.

Why are most of Selangor’s quarrying activities carried out in Bukit Lagong forest reserve?

  • FRIM and the Sungai Buloh Leprosarium have found tentative listing as UNESCO World Heritage, supported by the Federal and Selangor governments.

FRIM: https://whc.unesco.org/en/tentativelists/6174/, mooted from the time of past D-G Latif Mahmood and continuing now towards full listing

Sg Buloh Leprosarium: https://whc.unesco.org/en/tentativelists/6388, proposed by Sungai Buloh Settlement Heritage Society apparently with support of state government via Exco members (YB Teng, Investment/Industry & YB Borhan, Rural Development/ Culture/Heritage)

The visual pollution from the southern block of proposed new concessionaires would impact FRIM and the Leprosarium (Pusat Kawalan Kusta Negara)

  • BLFR is a treasure trove of biodiversity. It consists predominantly of intact, high quality forest which has not seen degradation from sometime before 1985, despite having been mostly classified as production (sustained yield timber) forest through to the onset of moratorium.

Please refer to Appendix 2 for more information.

9)      The impacted/potentially impacted communities include:

  • Two closest Orang Asli (OA) villages – Kampung OA Hulu Kuang, and Kg OA Sungai Buloh, both within 1 km of existing operational quarries and whose water sources are downstream of the drainage zone of the new concessions. There is also Kg OA Bukit Lagong although farther than the other two villages from the proposed quarries would still be affected since their forest would be much reduced.

The clean clear Sungai Buluh flowing through Kg Orang Asli Sg Buluh
  • Residential area in Rawang (Taman Tun Teja and Kg Sg Samak), currently two non-forest reserve quarries already operating in their area. New concessions would add to the current baseline of issues faced.

10)  Forest Reserve quarrying in a broader context (for Selangor):

Publicly available data on quarry production state-wide is sketchy. Some of it suggests that Forest Reserve quarrying may account for 25-30% of the total.

Does Selangor actually need to quarry Forest Reserves?

Selangor state has the largest economy by GDP, also typically at or near the top of ‘overhang’ (i.e. unsold properties) statistics. Seen in this context, policy reform on quarrying should be a component of a wider re-balancing of development strategies to guide land use, sectoral and environmental policies. There is no evidence of this being systematically undertaken by the state’s economic planners (or maybe there is, but as a government-industry dialogue to the exclusion of civil society stakeholders).

Forest conservation is among the strategies to tackle climate change. Malaysia has committed to maintaining 50% forest cover as declared via the Langkawi Declaration during the CHOGM 1989. This commitment has since reiterated during 1992 Rio Summit and by National Land Council (NLC) chaired by the Prime Minister of Malaysia and all states of Malaysia represented by Menteri Besar and Chief Ministers. As the state of Selangor stands with less than 50% forest cover, it is the role of the state government to ensure the maintenance of 50% forest cover. There should not be any deforestation for commercial use. Any request for quarrying for commercial need can be sourced from existing private land, if need be state government should assist in acquiring the suitable sites for quarrying.

Role of state GLCs are to initiate and to support/sustain strategic activities which are not commercially attractive for private sector. State GLCs involvement in commercial activities gives unfair advantage due to state government as the owners

All government agencies should not in any way be involved in conflict of interest activities including kelab sukan kakitangan and koperasi kakitangan.  They should never be involved in activities under the jurisdiction of the agency which exposes weakness in compliance monitoring and enforcement duties.

11)  Impacts of Forest Removal on Climate Change

Climate change is an existential threat5 facing us, i.e., it could mean human extinction. It is due to our carbon emissions. Forest destruction contributes some 15% of the global CO2 emissions. Furthermore, tropical forests absorb more than half of the total carbon absorption6. Thus, every effort must be made to reduce emissions. Forests must be conserved not destroyed. Also note that the National Land Council (MTN – of which every Menteri Besar and Chief minister is a member) in 2014 virtually prohibits quarrying in Permanent Forest Reserves (PRFs)7. The proposed quarries are in the PRFs of BLFR.

12)  Impacts on Clear-Felling of Forest Pre-Quarrying

Forests are clear-felled (totally logged) before quarrying can start. Water retention by forests affects the amount and timing of the water delivered to streams and groundwater by increasing and maintaining infiltration and storage capacity of the soil.  When the forest is cleared, excess rainwater is not soaked up, increasing run-offs and flooding. Debris and soil erosion will worsen floods and especially impact the nearest villages to the cleared forests, i.e. the two Orang Asli villages, Kg OA Hulu Kuang, and Kg OA Sg Buluh. This was seen in the recent floods in Pahang and Baling, Kedah when forests in the hills were clear-felled.  

The Selangor state government imposed a 25-year moratorium on logging starting 2010.  Allowing quarrying in forest reserves not only goes against the government’s moratorium on logging, it also extremely destructive.  How can the state government still call the quarried areas forest reserves?

13)  Impacts of Quarrying on Orang Asli Villages

The quarries will result in the streams and rivers that start from the quarry areas to be muddy and unusable by the villagers. One is Sg Kuang that passes through Kg OA Hulu Kuang. Another is Sg Buluh passing through Kg OA Sg Buluh.

Animals and Biodiversity of Bukit Lagong Forest Reserve

27 Oct 2022

Bukit Lagong Forest Reserve (BLFR) is a very healthy, rich forest just outside Kuala Lumpur, next to Jalan Rawang and across Templer’s Park. It is very unfortunate if the planned quarries of 800 hectares (Ha) in it were to be carried out which would destroy this richness. This rich biodiversity forest at present can be seen in the animals found there.

Importance of keeping forest intact

When habitats of rare and endangered species are reasonably undisturbed, they can persist forever. Examples from Bukit Lagong are:

1.    the very rare begonia, Begonia aequilateralis, that is so rare it is known only from Bukit Lagong and Sungai Buloh (the latter location was probably destroyed when the Sg Buloh nurseries were established),

2.    the rare saprophyte Thismia alba that is confined to natural habitats (How to grow it  ex-situ is not known, i. e. outside the forest), and

3.   the rare dipterocarp hybrid only known from two other localities. That three species of conservation importance are found in Bukit Lagong, shows how important it is as a natural heritage.

Animals

According to information provided by the villagers of Kg Orang Asli Sg Buluh there are a number of important animals that can be found in BLFR (see the complete list, attached). Several of them are threatened species. There are two that are critically endangered (CR) – the highest threatened category, before Extinct – as categorised by the IUCN (International Union for Conservation of Nature) Red list status1 (see notes on IUCN threatened categories below): the Sunda Pangolin (Manis javanica, Tenggiling), and the Helmeted hornbill (Rhinoplax vigil, Enggang tebang mentua). The Sunda Pangolin is the most trafficked animal, used in Chinese traditional medicine2. And the Helmeted Hornbill is poached for its ivory-like solid casque3, unlike the casques of other hornbills that are hollow.

There is also the Endangered (EN) Southern pig-tailed macaque (Macaca nemestrina, Monyet beruk). Then there are the vulnerable (VU) animals: Sumatran Serow (Capricornis sumatraensis, Kambing gurun), Black Leopard (Panthera pardus, Harimau kumbang/bintang), and Clouded leopard (Neofelis nebulosa, Harimau dahan). It is amazing that all these wonderful animals are available in Bkt Lagong.

Butterfly Survey

A butterfly survey of BLFR obtains 73 species (identified with several more unidentified – for lack of time and need for more photographic views, upperside or underside.  See the complete list below). A survey of Shah Alam Community Forest in 2020-21 identified 78 species. But this was achieved in 24 trips whereas for BLFR it was obtained in only 11 trips (for lack of time for more trips). This shows BLFR is a rich good forest. Of the 73, forty seven are forest and other-habitat species, and of the 47, twenty five are only available in forests, again indicating the health of BLFR. One of the forest-only species is the rare3 Dried-leaf Palmfly (Elymnias saueri saueri, Palma Daun-kering). Among the denizens of deep shade forests are the Blue Catseye (Coelites epiminthia, Matakucing Biru), Narrow Striped Faun (Faunis gracilis, Dewa Belang Sempit), and the Malay Red Harlequin (Paralaxita damajanti, Gemilang Merah Melayu)

Bird Survey

A quick three-day bird survey obtains 31 species (see the complete list below). There is one Endangered species, the Greater Green Leafbird (Chloropsis sonnerati, Daun besar). Apart from the Critically Endangered Helmeted Hornbill (Rhinoplax vigil, Enggang tebang mentua) there is another hornbill in BLFR, the iconic and Vulnerable Rhinoceros Hornbill (Buceros rhinoceros, Enggang badak). The presence of these two largest hornbills again indicates that the BLFR is a healthy forest. Even though the SACF is a good forest you don’t find these two there. The villagers of Kg OA Sg Buluh too reported the presence of the Vulnerable Great Argus (Argusianus argus, Burung kuang – also heard during the survey). This is a magnificent bird, and together with its mountain cousin, the Crested Argus (Rheinardia nigrescens), the largest ground birds in the Peninsula.

The presence of these animals, especially the threatened ones, in BLFR would be further threatened if the quarries were carried out, which at 800 Ha is a substantial portion of BLFR.

Another worrying fact compounding the already threatened status of the animals: all of them show a decreasing population as assessed by IUCN indicating that their status is just going to get worse.

Flora Bukit Lagong

1 Shorea curtisii (also called Seraya)

Conservation status IUCN Red List: LC

2. Shorea curtisii subsp. Curtisii

A natural hybrid found only in 2 localities in Peninsular Malaysia – Bukit Lagong FR in Selangor  & Pasir Panjang FR in Negeri Sembilan.

Also recorded in Bukit Timah FR in Singapore.

https://portal.cybertaxonomy.org/flora-malesiana/cdm_dataportal/taxon/9e99b4b7-180c-4a51-b45b-396998dc205a

Small groups of hybrid trees between this species and S. leprosula exist on Bukit Timah, Singapore and Bukit Lagong, Selangor; subspecies grandis may have the same origin. The two species often occur together at the margin of their respective ecological ranges, and it is curious that morphologically intermediate trees are not more common.

Natural hybrids also discovered at P.Panjang, NS
https://www.jstor.org/stable/26872824

This study established natural interspecific hybridisation in a particularly important tropical timber group, Shorea. A mature putative hybrid of Shorea leprosula and S. curtisii discovered in Pasir Panjang Forest Reserve, Negeri Sembilan showed intermediate morphological features when compared with S. leprosula and S. curtisii.
