My first module in Madagascar was two weeks of conservation work, which included a lot of random things - including the bee keeping/bee hive building you saw a couple of posts ago. Another aspect of this module was to prepare little plastic bags of manure and sand (aka. pot-packing or shit-packing) for trees to be planted in them to mature in the tree nursery across from our camp ground and then be planted in the wild in the future. We also monitored some trees that had already been planted to see how they were growing. We gauged their progress by taking notes on how the soil in a transect (or line) was supporting other plants or if only sand or rocks were present (which in the long run is going to make it harder for the trees to thrive). I got stung by a hornet one day while taking notes but the other bugs and animals we saw made that worth it.
