[Mastwatch] Casual observations at Gunung Palung

Hi Serge,

Bear in mind that free standing trees, in botanical gardens or even selectively logged forests, do tend to flower more frequently, that is outside mast years (see literature by Appanah, Yap, S.K., Ng, F.S.P. etc on experience from the Malaysian Forest Research Institute)

Hi everyone,

Thanks Andy, good to hear about the mast. Here in the north of Sumatra we think we have a mast up in the far north on a new orangutan reintroduction site we just opened. We are collecting data there on phenology so with hindsight I hope we will be able to tell whether this was a true mast. In another area up in the hills 45 minutes from Medan in an old botanical garden there seems to be a mast as well, but we have no data from there, but when I visited many species were flowering. Unfortunately Andy and I share difficulties at our research sites and we have not been able to collect our regular phenology data in Ketambe so we have no info from there on the mast. A real loss, but the site was closed due to political reasons for a few months.

I also have a question. With all the mast info from casual observations and phenology datasets I was wondering whether there is a sense in putting all of this in a database that is or is not spatially explicit and perhaps do some analyses on it. It would still be nice to understand more about masting and where it occurs and how synchronous it is over larger areas or what time-shifts are between areas. I have no idea how much data there are, but it might be something to try to do together?

Hi everyone,

            A quick note from Gunung Palung. I was just up at Cabang Panti, our research station. It was a short trip, so I didn't do any focused pheno work myself (although our assistants are still doing monthly monitoring of stems in our plots). But I did notice that a several Shorea individuals (including, but not limited to, S. quadrinervis) were fruiting, along with a few other taxa that seem generally to restrict fruiting at our site to community-wide masts (e.g., Willughbeia, Diospyros,  Dillenia, Whitfordiodendron). I'll let you know when we know more (assuming we are still collecting data- our park head has just ordered the site closed temporarily to deal with illegal logging in the site, which has already affected one of our long term plots).

Hi All,

Things are about to start flowering in Sepilok. I did a quick check on some of the Dipts that lead off our GF events (Shorea confusa and Dipterocarpus applanatus) and have flower buds on these. These are relatively rare species in Sepilok i.e. only 3 and 5 individual in our 160 Dipt plot - so it is hard to know at this stage how big the event will be.

I also have bud starting to develop on Shorea xanthophylla - but at this stage they are tiny and can only be see when you are in the canopy.

Last year we had about ~60% of the adult dipts flower i.e. 3253 trees of the 5549 in our 160 ha Dipterocarp plot flowered.  We saw lots of variation in terms of the % individuals that flowered among the different species ranging from 0 % in Anisoptera costata up to 93% for Shorea multiflora.
