MAP's EMR Project at Ban Talay Nok. A successful conclusion to their mangrove work

Chums. Happy Christmas.

This is a 10 minute film that draws to a conclusion the work MAP has accomplished in Ban Talay Nok. Despite the land tenure and control difficulties, Jim and Ning have done incredibly well, and are held in great respect by the village. Please take time to watch it. The physical work is in a different style to BLD but uses the same thinking as my project.
Hope 2010 is muddy and successful
Very best

MSc in Sustainable Development (Imperial / SOAS)

Delighted to tell you that the MSc is now officially dead. 76% for the research report ensures that the overall score is a Merit. So, back to the UK for graduation in March (15th) and perhaps a couple of warm flat beers. Thank you to all the people who have helped, researched with me, supervised, read bits, translated questionnaires and put up with my whining.

The Mud Lobster Takes a Holiday

Dear Friends
Just to let you know that I'll be out of Thailand for about a month, on leave in the UK. So the postings will slow, somewhat. But please feel free to get in contact. The email will be checked every so often.
Happy digging.

Mangrove Rehabilitation in Colombia

This is a link to a youtube video. Please follow and watch the 6 minute film. It documents mangrove work by Prof Heliadoro Sanchez in Colombia. There are some interesting parallels with Bang Lang Da. An amazing man.

Deep and Wide and Painful

So, what's been happening down in the mud? A previous entry has described the visit from Japan, organised by the Ramsar Centre of Japan. Thrilled to say that now my MSc is completed (mid Sept). So for the last few weeks a lot of digging has been committed, and the plant data have been charted (next blog). As per a previous update what Jim and I discussed doing was widening and deepening the start of the main channel (2) from the sluice gate across the centre of the pond. This has been done, and produced some more hills, including A2, B2 and D2 (yes, we've gone round the alphabet already). Much has been learnt during this process. It's been hard slow work as the channel is already quite deep. Thus taking the sides back and sloping them over means shifting a huge amount of soil. Often there are a series of drainage holes on the surface near the edge of the channel. These holes mean that any soil below is not going to be that strong or stable. Therefore the subsoil has to be dug out. The implication of this is that sometimes the sides of a channel have to be lent right back to remove this unstable soil, (ie a LOT of digging) and to keep the weight off what is left. Otherwise the sides of the channel collapse inwards. The picture below is looking up the channel, which I was standing in at the time of taking this picture. At the top is what the original channel looks like, unaltered. The pool in the middle is an example of the excavation, the new channel floor being two feet lower than the current channel bottom. Near to me, the sides have collapsed inwards.
The soil itself has a very high clay content. Often it was possible to cut pieces out like blocks of cheese.
There have also been some amazing colours in the clay; yellows, light blues and reds. Though this might look like strata of sand, a 'finger test' of the coloured material revealed that it had the same consistency as normal clay.

Needless to say, because this channel is the lowest point on the site, it could only be worked at the lowest tides. It is only possible to work from the sluice gate upwards, not working downstream. However, because the total volume of water leaving the pond during any one tide is not great, the bottom of these new channels becomes filled with very fine silt and clay, rather than being scoured by the movement of the water.
When the tide was too high to permit work in Channel 2, a new branch (2D) has been excavated. 2 denotes that it drains into the main channel running across the pond. D as it's the fourth sub-channel to be created. 2D has been excavated as carefully as possible, digging out loose soil in the slopes, sloping the sides over as much as possible, trying to keep the hills made with the spoil back from the edge of the channel so their weight does not cause a cave-in and not excavating in a straight line. Below is an early picture of 2D coming to life, with some interesting if unmoved woodwork in the middle.
The new hills have been labelled and marked up on the map at the top of this blog. Some of them will be left blank to monitor natural regeneration. Some have been dibbled with seeds and propagules. And some have received test transplants from home. Over the course of this year I've been collecting seeds and growing them at home, to be able to watch their development. It has allowed me to experiment with various ideas, and look at tolerances. As I'm going on holiday Oct 22nd for a while, these mangroves are now being transported to the site - in some style, I might add.
Hill Y has received a pot of Rhizophora apiculata (above) from home, all of which had damaged buds. They have managed to recover from this early trauma and grow normally. Hill R has taken three Nypa fruticans palm plants. These are a species the local people use for their own livelihoods, so the site, once fully established, will have a good proportion of Nypa. These have been grown at home, and will be measured, monthly with the other hills that are monitored.
Two friends are visiting me from the UK. Over the weekend we will go to BLD and do the monthly measuring of all the plants being monitored. In the subsequent blog some of the initial data will be presented. In the meantime Rossi is back on his bike this weekend at Estorill, Portugal. Go Rossi!

Visitors from Japan

The beginning of September saw some pretty terrible weather in Krabi, lightened by visitors from Japan. This time the group was under the auspices of the Reiko and Musha (below)from Ramsar Centre of Japan, and supported by Emiko and Tomoko from the Environment Restoration and Conservation Agency of Japan and Dr Sansanee from Mahidol University. Their student group of undergrads and postgrads included an interesting mix of subjects including law, architecture, agriculture and fresh water lake systems. The Krabi visit was only one small part of a gruelling three week tour covering selected parts of southern Thailand, followed by a similar tour around Bangladesh.

In three days they managed to squeeze a lot into their visit. First was a walk around the ‘Two Waters’ Ecotone, where a freshwater forest gives way to a brackish water system. Then a visit to The Ammartpanichnukul School in Krabi to hear from the students about their mangrove work, and for the Japanese guests to present some aspects of Japanese life. The school then treated us to a great lunch in a nearby restaurant. Krabi Provincial Office played host that afternoon, and the group met the leaders of the KPO and K’ Asae, Director of Wetlands International – Thailand Office. In the evening we were all treated to a delightful dinner by K’ Sajjaporn from KPO.

The next day the group took a boat trip around the Krabi mangroves and out as far as the bird watching towers. Sadly the weather was not kind, but the visitors were well kitted out with wet weather gear. Bang Non, our boatman and a conservation worker within his own community, presented what he had done to collect and recycle waste from his village in Klong Prasong, helped by Dr Sansanee, and also put on a fabulous lunch, despite it being Ramadan.In the afternoon the Wetlands team presented the work done at Bang Lang Da, before travelling to the village. Bang Don explained to the group the crab rearing and fattening process before looking at the rehabilitation pond. Sadly the rains returned so we beetled back to the vans and had banquet with the great and the good of Krabi, hosted by the RCJ.

On their last day we excellent dimsum, again with K Sajjaporn, before an informal trip to the morning market and an OTOP batik shop. Thus, sadly, our new Japanese friends left for Bangkok, and the next day Bangladesh. Come back soon.

The Mud Lobster Takes a Study Break

Please forgive the apparent inactivity. Several things are happening at the same time. First, it's charts and formatting time for my MSc research report. The end is in sight. The light at the end of the tunnel is on and I'm blinking. But it's a slow fiddle, with some bugs appearing in MS Word. Second, we are thrilled to have a Japanese study tour organised by Wetlands International and The Ramsar Centre of Japan visiting Krabi. More on that later. And third, in order to have something to present, a seriously overweight powerpoint presentation is in production, for my new Japanese chums. We hit the 100MB barrier on Tuesday night and we're going strong.
More anon.
