Jan Wieringa pressing plants in Swaziland

I have a wide interest in plants and animals, with a geographical focus on Europe and Africa. My oldest interest is insects, in particular grasshoppers and (bush)crickets, but I take an interest in beetles as well. Of the various plants I have studied I am most keen on legumes and Begonia. A recent project deals with Cassytha in Africa; these are parasitic climbers of the Laurel family. I am especially knowledgeable about the flora and fauna of Gabon, where I have spent over 2 years doing fieldwork.

Next to this taxonomic and floristic/faunistic work, I like to assemble specimen distribution data to produce  biodiversity studies, particularly on African biodiversity.
