Mandena and the Write-Up

April 29, 2012 at 12:51 pm 2 comments

Bonjour, bonsoir! I spent this last week being an academic machine. From Monday to Wednesday, I collected orchid data in the littoral forest of Mandena. Since then, I’ve been putting together my data from the three different littoral forest sites to create a write up which is, as of this morning, finished. Hooray!

In the three different sites (Sainte Luce, Petriky, and Mandena), I found a total of 39 different species — a huge jump from 18 species, which is what was reported in the past. More than double! And when you combine these two lists, there winds up to be a total of at least 45 different orchid species in the three sites. This newly places the orchid family (Orchidaceae) in the list of the top five most highly represented vascular plant families found in the three zones.

Along with updating the list of orchid species found in the three zones, I also compiled a list of tree species that commonly serve as hosts for epiphytic orchid species in these zones, and I found that the percentage of terrestrial versus epiphytic orchid species differs between zones. Additionally, certain orchid genera turned out to have more species in some zones than others. These results helped me create a write-up of which I am very proud. I hope all the information I gathered will be of use to QMM as they monitor these littoral forest sites and execute their conservation efforts within them.

Now, please enjoy several pictures of orchids and of other forms of biodiversity!
