Loagan Bunut National Park, the park is bounded by Sg Teru on the right and Sg Tinjar on the left (image by Sara Wong).
CFZ assessment track 19th March 2011.
Nighttime Assessment of Sungai Teru
View of the lake from the lakeside, there's already plenty of signs that there'd be rain there that night.
We weren't able to collect samples along our traverse due to subjects were displaying high on the display trees. Initial assessment suggested that the species are large with greenish flashes. Rovers recorded were also of large size.

EC test in the lab 21st March indicated readings of less than 60 microS/cm; fresh with ver low mineralisation.
The survey was terminated earlier before intended end-point (ie. Sg Teru Bridge) when the rain conditions worsened, thick cloud cover and we lost satellite signals due to prevailing conditions. There was consensus among the team members that more display trees could lie ahead on our planned trajectory.
Though initial sightings were only of rovers in low numbers (1-10), firefly counts reached high numbers starting WPT 150 and remained throughout with visible display trees on both banks.
Towards the end counting was made slightly difficult with the prevailing rainy conditions. It is worth noting that throughout this survey, the rain did not let up from start to finish, in fact got heavier until the termination point.

It is recommended that another survey be initiated along these traverse to fully assess potential for more firefly display trees within the Loagan Bunut National Park boundary:
a) continue along Sg Teru towards Sg Teru bridge,
b) continue downriver along park boundary
c) Loagan Bunut water's edge.
Happy faces on the way to our first WPT for our CFZ survey of Sg Teru.
Soaking wet, our point man, John, lighting the way back after heavy rain. The downpour didn't stop until after we reached the park hq and drank up all of our coffee.

With present good facilities (accomodation, availability of boats) already well established within the park, presence of firefly display trees could augur well for fireflies and the park itself.
(Final data will be posted when coordinates have been processed).
Side note:
The road to Loagan Bunut is just slightly better than previous years though we saw loads of construction work being carried out along the way. Travel there is not adviseable without a credible 4WD or in heavy rain. One stretch of road is forever prone to flooding during the wet season. Our two 4WDs survived without a scratch but covered with mud!
