About Us And Our Mission | Biosphere Expeditions

Biosphere Expeditions was founded in 1999 and is first and foremost an award-winning citizen-science-based wildlife conservation non-profit.

We believe that climate upheaval is now locked in, bringing biodiversity loss and civilisational convulsions in its wake. Biosphere Expeditions accepts this reality without illusion. Moving forward from our 2026 manifesto for a troubled planet, we have purged all commercialism from our operations. We reject performative hope and "save the planet" narrative spin. Instead, we deploy non-commercial citizen science to execute rigorous conservation triage, creating and extending biodiversity refugia while empowering the local stewards who protect them.

Far from an exercise in gloom, embracing planetary realities provides profound meaning and integrity to our work. It offers executive leaders, professional and citizen scientists and local partners the certainty that their effort is not a symbolic gesture in a losing battle, but a targeted intervention giving functional ecosystems a fighting chance through the global transition.

More about this in our mission statement and operating principles.

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 aim to make a difference to our biosphere and at the same time bring enjoyment and fulfilment to our teams of international wildlife conservation volunteers. We do not run tours or just wildlife conservation holidays, but genuine wildlife research expeditions, based on good citizen science and ethical volunteering principles. And we succeed - the creation of protected areas on four continents is just one example.

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 within a volunteer holiday setting. 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 holiday volunteering opportunities 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 eyes in the future. Please join our efforts!

Then, as we were putting more emphasis on campaigning, the coronavirus appeared, to be declared a pandemic in March 2020. From then on, there were no more holiday volunteering opportunities for people. Almost immediately, in April 2020, we started to run a fundraiser that was all about getting our local conservation partners through the crisis. This ran until the end of 2020 and raised €50,000 (an overview of what this money achieved is on our blog). In February 2021 we announced that there would be no volunteer holidays in that year either. This meant that there was to be next to no income for us for close to two years. With this, our survival was at stake, so we started our own survival appeal, which ran until October 2021. Once again many generous donors (many of them repeat donors from the coronavirus fundraiser) stepped up and we were able to raise € 30,000 to ensure our survival through the crisis. In October/November 2021 we ran our third fundraiser to make sure that all our local support staff and helpers (and their immediate family) are vaccinated. This raised over € 5,000.

Through the generosity of many donors in 2020/21, we were able to pull through the pandemic and help our partners to do so too. Operations re-started in 2022 and since then we have, amongst many other things, discovered a very rare white whale in Azorean waters, wild dogs in Vwaza Marsh Wildlife Reserve, published a "Reality Check" issue of our Annual Magazine, won more accolades and continued to empower local people and international citizen scientists to help hands-on in wildlife conservation across the globe.

In 2024, we celebrated our 25th anniversary, amongst other things with the publication of a coffee table book.

In 2026, given the state of the world, we published a manifesto for a troubled planet. With this we performed a radical pivot away from all commercialism in our operations, rejecting performative hope and "save the planet" narrative spin. Instead, we now deploy non-commercial citizen science to execute rigorous conservation triage, creating and extending biodiversity refugia while empowering the local stewards who protect them.
