A first for Jersey – Snail surveys

I am doing some slug and land snail surveys in order to discover the diversity and richness of the island. This involves identifying and recording a group of organisms about which we currently know very little. Indeed, no data have been recorded yet.


What do I really do?

I go to some places and follow a specific protocol in order to ensure my data is replicable. All areas are concerned: dunes, lands, woods, and gardens as I want to cover all species.

Once I am there, I choose three small quadrats of 1 meter square representing all major habitat types of the site. The ideal is to cover different mollusc micro-habitats, so the best is to choose quadrants faraway from each other.

In each quadrat, I check by beating, sweeping, hand search and direct observation the ground, and plants during half an hour and collect all species found.

Then, the other step is the identification. To do so, I use different books and the internet. I follow the keys, in order to obtain the name of the specie. I use hand-lens (at least x8) and a ruler. And I do not forget to take a lot of pictures.

So now Jersey, you will have some new data concerning land molluscs!
