I am a diversionistic naturalist all my life . As a boy , I learned to work with scientific names and nomenclatur . Also , I have been working with flora and fauna professionally since 1978 . I have travelled in Colombia , Ecuador , Peru and Venezuela in 1984 , 1986 , 2000 and 2002 . Mostly on my own in the amazonian rainforest . In 1987 I was working in Arusha , Tanzania , collecting plants and animals . Nowadays I am retired , and my operational modus is limited to my hometown , the forest and the dunes nearby . Best regards , Joost Nieuwenhuizen .
