Biosphere Expeditions was founded in 1999 and is a citizen science wildlife conservation non-profit first and foremost. We fight for a more sunstainable planet, which is under attack like never before, by empowering ordinary people to help with wildlife conservation and research through our international expeditions, working hands-on as environmental volunteers on wildlife conservation holidays all across the globe.

The term "Biosphere" was coined by Russian scientist Vladimir Vernadsky in 1929 and is defined as "the part of the Earth's surface and atmosphere occupied by living things". This encompassing term, we believe, is a fair reflection of our mission. With our citizen science conservation expeditions we make a difference to our biosphere and bring enjoyment and fulfilment to our teams of environment volunteers. We do not run tours or just wildlife conservation holidays, but organise real conservation expeditions with genuine wildlife conservation aims that produce real results and achievements. Our wildlife volunteers can be secure in the knowledge that they will not only have an exciting conservation holiday with a purpose, but also a productive time in conserving part of our global natural heritage.

Expedition leader in training
Roland Arnison

Roland Arnison studied Environmental Science and is a qualified Mountain Leader, a Mountain Rescue volunteer and has led on a variety of expeditions in the UK, Canada, Iceland and Namibia, including introducing young people to the joys and challenges of expeditions in wild places. He has run expedition citizen science projects ranging from sampling for plastic pollution in the ocean to searching for the elusive Collared Pika in the Yukon as a bio-indicator of climate change. Roland’s mountaineering exploits have taken him to un-climbed peaks in the Himalayas and equally challenging times in the Scottish hills in winter. Roland enjoys kayaking, climbing, cycling, filming, photographing, diving and sometimes just walking in some wonderful and wild parts of the world. He has also spent many years looking after a smallholding in Yorkshire, creating wildlife habitats, and experimenting with novel food growing and renewable energy projects.

Rossella Meloni
Rossella Meloni was born in Italy and has lived and worked in the UK for 12 years before experiencing life further afield by living in Muscat (Sultanate of Oman) and Seoul (South Korea). Rossella studied languages in Italy and gained a BSc in Computing and Information Systems from the University of Portsmouth. Since her first cautious breath underwater, well over a decade ago, she has become increasingly interested in the beauty and welfare of the underwater world. Her love for the marine environment and the outdoors encouraged her to join her first marine expedition in 2006 spending 6 weeks in a remote coastal village in Madagascar and later to continue training as PADI Open Water Diving Instructor. Her passion for diving and nature has led her to volunteer in remote areas of the world and eventually to lead expeditions with Biosphere Expeditions. When she is not busy tinkering with technology, leading expeditions, volunteering or supporting environmental causes, she can be found exploring the outdoors and pursuing new adventures. She is also a City & Guilds trained photographer, a RYA competent crew, a keen kite surfer and a qualified Emergency First Response trainer.

Tien Shan
Volodya Tytar was born in 1951 and his Master’s Degree in Biology is from Kiev State University. At that time he first experienced the Altai mountains and wrote a paper on the ecology of the brown bear in the Altai. He then pursued a career as an invertebrate zoologist before shifting towards large mammals and management planning for nature conservation. Apart from the Altai, he has worked with Biosphere Expeditions on wolves, vipers and jerboas on the Ukraine Black Sea coast and has been involved in surveying and conservation measures all his professional life. 

Biosphere Expeditions started in 1999 as one of those famous "in the shower" ideas. Our founder, Matthias Hammer, with a military career behind him, some student expeditions under his belt and disillusioned with the ivory tower mentality of academia, was looking for a way to combine his training as a biologist with some real-life, hands-on conservation work. When someone suggested "why don't you take people on expedition with you", the idea for Biosphere Expeditions was born.

It took a year to set up Biosphere Expeditions as a non-profit organisation in the UK and another year to recruit the first expedition team. The first expedition ran in 2001 to Poland, studied wolves of the Carpathian mountains and was instrumental in establishing a wolf hunting ban there. Demand was high and many expeditioners, once bitten by the bug, came back for more, so the expedition portfolio quickly increased to include Peru and the Azores, the latter still running today.

More expeditions were added, the Friends of Biosphere Expeditions came into being, awards won, and the media took a great interest in Biosphere Expeditions. The German office opened in 2002, followed by France in 2004, North America in 2006 and Ireland in 2017. As volunteering became more popular, shady and unscrupulous operators started moving in to exploit people's goodwill, so our first campaign was the Top Ten Tips on how to beat the charlatans in voluntourism. In 2018 the HQ moved from the UK to Ireland in Biosphere Expeditions' very own Brexit in the wake of the UK's increasingly anti-European and nationalistic agenda.

In 2007 a new website was created and Biosphere Expeditions diversified to offer 2-week expeditions and 1-week projects across the globe, as well as experience days in the UK and Germany. In 2014 another completely re-designed website was launched to reflect and showcase the many areas that Biosphere Expeditions is now active in from conservation successes to capacity-building to involving local communities. Another overhaul of the website in 2018 saw the expeditions portfolio grow to 14 and the achievements stretch over four continents.

Over the few years all this was rewarded and recognised through of awards and accolades such as “Best Volunteering Organisation” (First Choice Responsible Travel Awards), “Top Conservation Holiday” (BBC Wildlife, UK), “Best Holiday for Green-Minded Travellers” (Independent on Sunday, UK), “Best New Trip” (National Geographic Adventure, USA), “Top Holiday for Nature” (P.M., Germany), “Environment Award” (from the German government), etc.

Next to this cornucopia of awards, Biosphere Expeditions also became an officially accredited member of the United Nations Environment Programme's (UNEP) Governing Council / Global Ministerial Environment Forum, the International Union for the Conservation of Nature (IUCN) and the European Citizen Science Association (ECSA).

In 2019 Biosphere Expeditions celebrated its 20th anniversary in two parts: During the first half of 2019, we looked back at our history and achievements in the 2019 annual magazine. We also used the opportunity, and seeing the signs of the times, to overhaul our policies to reject neoliberalism and the fairy tale of continuous growth on a finite planet as well as destructive corporate sponsorship, whilst at the same time going vegetarian. During the second half of 2019, we followed up on this: In our first 20 years, we were focused on citizen science and wildlife conservation. We pledged to continue with this focus, but this, we felt, is no longer enough, because the undeniable crisis our planet is in demands more action and activism. It demands a radical rethink of how we run our lives, societies and the way we treat our planet. Our answer was more campaigns such as our 20 tips on how to be (radically) greener, our Do More campaign or our tips on how to beat the volunteer charlatans. Our 2020 annual magazine mirrored this new development of more activism and campaigns for our planet. We have a duty to act if we want to be able to look our grandchildren in the eyesin the future. Please join our efforts!


So we created the 20 tips on how to be (radically) green: from the light green of what we should all do as a bare minimum, to the dark green rejection of neoliberalism and the fallacy of endless growth, to joining the climate revolution. Because sitting on our hands is simply not an option any more. We felt strongly that we have a duty to act if we want to be able to look our grandchildren in the eyes.
