CSI with Sri Kuala Lumpur International School

Our CSI programmes are usually conducted for local schools but occasionally we conduct such programmes for outstation schools,private or corporate groups. Programmes are held at the Sg Pauh site which is within  the Forestry Department grounds. Each programme will start off with a briefing, followed by physical,chemical and biological analysis of Sg Pauh (the clean river) and Sg Bertam ( the contaminated river). The facilitators are usually Dr Liau or Miss Melody Woon and they are assisted by a few volunteers.

CSI with SJKC Kuala Terla on the 9th November 2016

The CSI activity with SJKC Kuala Terla was carried out over 2 days to accomodate more students and below are the pictures taken on the 2nd day. The programme on both days are similar.    dscn4878 dscn4880 dji_0103 dji_0096

CSI with SJKC Kuala Terla on the 8th November 2016

A limitless expanse of hills – dark green with diagonal bands – stretched out before me in the misty morning light.Suddenly, with a flurry of noise, a flock of yellow-vented bulbuls took off in unison over the cusp of hills.Although Cameron Highland’s broad swathes of nature are always breathtaking, her small details are no less amazing.

This is probably best encapsulated in Gunung Brinchang, a colossal hill covered in montane forests.The trees here teem with the sweet calls of fire-tufted barbets chirping over one another, and the murmur of the wind.

It is difficult to think.

A flutter of wings in the sea of gerok trees caught my eye, and I start towards its general direction before I catch myself. For a moment, I had forgotten my purpose.The highlands does not release its enthralled guests easily.


8th November 2016

Today was spent out in the sun with 30 students and teachers from Kuala Terla Chinese Primary School. It was my first time taking part in REACH’s Community Stream Investigators programme, and volunteering as documentarian.

The programme began with a detailed introduction by Ms Melody Woon, who explained about the many physical, biological and chemical tests that can be conducted to determine the quality of water running down the rivers. This was followed by talks on how the highlands have been polluted and damaged by overdevelopment.dscn4660dscn4662

Community Stream Investigation on the 21st September 2016

by Oon Yan Yan
Everything began when Melody happily volunteered both Sue Sze and I for Regional Environmental Awareness Cameron Highlands (“REACH”) programmes during our trip to Cameron Highlands. She believed that we will learn much from the programs and understand why she is fighting so hard for Cameron Highlands. She explained repeatedly to us the after effects of deforestation, pollution of the rivers and the effort that REACH had been doing over the years. To be honest, it was not that easy to absorb all of the information as it sounded quite foreign to us.dscn2456
On Wednesday morning (21 September 2016), we participated in Community Stream Investigation (“CSI”) with the students and teachers from Kea Farm Primary School. Dr Liau gathered the teachers and the volunteers for a brief introduction of CSI. He also explained the tests, i.e. physical, biological and chemical tests in detail which would help us understand what we were going to do later at the rivers. I was grateful that Melody shared her experience previously which made everything clearer after Dr Liau’s explanation.dscn2458dscn2460dscn2461

Tales of a thousand bugs

Bugs tell tales. Our community stream investigation CSI activity is based on this. We use the presence of bugs ( in this case macroinvertebrates) to gauge the quality of the waters in our streams and rivers. The beauty of this water testing method is , it is free and in “real time”. CSI is sponsored by CIMB, Prince Tunku Imran and Mr Paul Chuah  and is another popular environmental based activtiy here. This activity would not be possible without our vice president Dr Liau Tai Leong and his volunteers especially Miss Melody Woon.dscn3339 dscn3347 dscn3328

On the 4th of October , they conducted a CSI programme for 32 students and teachers from Convent Primary School in Tanah Rata ( SK Convent) .

Dr Liau first briefed the students on the physical and biological indicators of water quality.  The highlight of this programme is to search for the bugs in the streams  and rivers .

dscn3376 dscn3367 dscn3365 dscn3363 dscn3362Pictures of the bugs are given to aid identification. Different bugs tell different tales. Macroinvertebrates such as dragonfly larvae and water pennies are only found in very clean water while leeches and mosquito larvae are found in dirty water.

CSI activity on the 16th July 2016 near Bharat Tea Estate
