Who are we?

Who is who in this slightly bonkers group of people? Read for yourself to find out that seemingly normal members of society can be barking frog mad.

Lars (Lasse) Bergendorf. Born December 1951 in Helsingborg in the south of Sweden where I still live. My early interest in nature and animals and some years as a scout grew me into an active bird-watcher in the early sixties. Around 1990 I got more and more interested in herpetology. And since the mid-nineties my travelling in the Mediterranean area concentrates to these amazing animals. I´m working with it-projects and support in a food-company outside Helsingborg. I also do some work in conservation-projects etc. for the Swedish herpetofauna. In 2002 I left analog photography and got into digital with a simple Nikon coolpix camera as a starter. Nowadays I shoot with dslr cameras. I first met with Anders and Per in 2002 and together with Tommi who is an old friend of mine, our web site club100.net became reality in February 2004.

Per Blomberg

Per Blomberg. I was born in 1966 and grew up in the small town Bara in southern Sweden. Early the interest in nature led me to the youth organisation Fältbiologerna where I met Anders. During a lot of excursions in Skåne (sothern Sweden) and travels to southern Europe, field herpetology became an increasing part of the interest. With profession as both architect and biologist; planning for a sustainable future has become my living. Today the university town Lund, not far from Bara, is the living place with temporary moves to other places in the world.

Tommi Sandberg. I was born in Stockholm in 1956 but moved to Helsingborg in 1963 and have stayed ever since. Started to watch birds and joined youth organisation Fältbiologerna in 1971. Field herpetologist since 1983. Also interested in insects, especially butterflys. Etcher at a magazine publisher by trade.

Anders Selmer. As a child I caught tadpoles like everybody else and some thirty years on I have not yet stopped...
I was born in 1968 and grew up in the same small town (Bara in southern Sweden) as Per did. My first real contact with European field herpetology was a trip with Fältbiologerna to Camargue in southern France in 1983. I had studied my Burton in detail beforehand and the number of species I saw was far higher than my wildest expectations. I was completely hooked after this. Ever since my holidays have been planned with field herpetology in mind. After four years in Cambridge, UK, he is now back in Sweden working with industrial waste water treatment.

The Herptiles is probably the most threatened group of animals in Europe today and to remain it needs great efforts in terms of conservation. The main threat is destruction and pollution of wetland and other habitats important to the animals. For some rare species collection also is a severe threat. With growing concern for the environment and nature, lots of action is taken to preserve areas and to restore destroyed environments.

Red listed species

The World Conservation Union (IUCN) has developed a Red List of threatened species on a global level and many countries have followed and made national red lists. The system follows the international criteria for the risk of extinction:

  • CR=critical threatened
  • EN=endangered
  • VU=Vulnerable
  • NT=near threatened

More information can be found at Societas Europaea Herpetologica and at the European Environment Agency.
