Survey length 17.8 km
I went to Balingian to attend my wife relative wedding on the 11 of March. Since I was there I want to take a CFZ survey of the river. The local folk said there are huge display of fireflies along the river bank at Kayu api-api. There also a huge crocodile at the upper river side.

I requested my brother inlaw to look for a rental boat. He could manage to rent a small fibreglass boat with a 5 hp engine. I went to Balingian petrol ksiok and found out that the petrol wasd finished. This is common to know that the gas station always have no petrol in it pump. So I went to Mukah to buy petrol that is about 56 km from Balingian.
My brother in law is very keen to do this survey because I told hom so much about firefly. He has made the boat ready even before four in the evening. I suggested that we go to Kuala Balingian at 5 in the evening and we start our survey from there when the sun set. This is to save time, and also we can make a day time assesment of the river.

We started at 5 pm . Along the river are lined up with nypah palm and in between are the berembang and Api-api trees. We saw few instances of silverleaf monkeys and Asian Black hornbill. There are 3 swift hotel along the river. Four long houses, two Log ponds and coconut farm are seen along the river.

We reach Rumah Geliga jetty where we stopped to wait for the darkness. As we sat on the jetty a man from the long house approched us. He introduced himself as Lutang Ak Usit. He is very frendly and we talk alot about is place and the fireflies. He seemed to understand about the importance of the fireflies. Just between the jetty there are two huge Api-api trees.. He said the fireflies are abundant at these trees. He told me about some of his visito, were afraid of the fireflies. Its their syncronising lighting seemed to be frightening them. The Iban is not having any stories about the fireflies. He invited us to his long house. I could not accept it because the sun will soon set. When it started to get dark he left us.
The wind blow so hard that there is no mosquitoes disturbing us. I presume that the fireflies would also not be displaying. I took water sample for pH and Sg. Then I reset the thermometer and lowe the externel sensor into the water. The thermometer will read the tempetrature reading and record the Lowest and higest temperature of the whole trip.

When it get dark we did not see any fireflies at the two api-api trees. Thus we started our survey up river. At 19:03 we spotted our first fireflies. The count was estimated at 200 individual. We took samples at this first display trees. As I was the only person that recoed wpt and count and noting which side of the river the display trees is. Then I devise a method of renaming wpt if the tree is at the left side of the river.
Though we did not see many display trees, but most trees we find fireflies display have more than 200 individual counts. The fireflies are not displaying probably it a neap tide period. That is correlatable with my fishing window. Or due to bad weather windy and a drizzling rain at some point.
We concluded our surver as we reach our Balingian jetty.
