The Crossbill Guides Foundation is basically a grass-root organisation of ecologists. Its core consists of young Dutch biologists, who founded the organisation from the notion that it is unacceptable that there is no good information available for non-scientists on Europe's most important natural areas. If we want to maintain, let alone increase public's involvement with nature conservation, the first thing that needs to be done is to invite people to see through the eyes of an ecologist / nature conservationist. We created a concept in which we think this target is best met: The Crossbill Guides.
Dirk Hilbers Director and Author
Dirk Hilbers is the founder and director of the Crossbill Guides Foundation and the main author of the Crossbill nature travel guidebooks. Dirk has been interested in nature since childhood and has been active in the NJN, the Dutch youth organisation for field biology, for many years. During his studies in ecology at the University of Nijmegen, Dirk found out he wanted to focus on nature conservation. The biggest challenge in this was to bridge the gap between conservation and the general public. Especially the conspicuous lack of information on the value of Europe's most important natural areas (Natura 2000) was an incentive to start the Crossbill Guides Foundation. He found himself a great job: combining nature trips and reliving them when writing the travel guides. Next to his part-time job at Crossbill Guides, Dirk also teaches topics like Science & Society, bioethics and science communication at Amsterdam University.
Board of Directors
Johanna Winkelman Board member
Johanna Winkelman has been active as a chairman of the Board of Directors for the Crossbill Guides Foundation since the start of 2014. She was familiar with the guidebooks before she became part of the board since she used them during her own travels. Johanna studied biology at the VU in Amsterdam and the University of Wageningen focusing on ecology, animal systematics and nature conservation in the (sub)tropics. She also decided to take another study in scientific journalism at University of Applied Science Utrecht. Johanna was awarded with many distinctions during her professional career at organisations like the Netherlands Society for the Protection of Birds, Birdlife International, Alterra Research Institute – Wageningen UR, and many more. Johanna’s main motivation and challenge is to take Crossbill Guides to another level. Increasing quality and publishing new books will create more awareness, which in turn will increase awareness for conservation of our beautiful European nature.
Theo Verstrael Board member
Theo Verstrael has been part of the Crossbill Guides Foundation since 2011. He was asked to take part in the organization as a board member during his time as principal at the Vlinderstichting (foundation for butterflies). Theo has studied biology at the State University of Leiden and became a specialist in ecology and environment biology. He started his career at Dutch Bureau of Statistics and worked together with Sovon (bird research) for many years. After 9 years of being the principal at Vlinderstichting, Theo decided to switch to bird research and became Principal of Sovon. Theo finds the Crossbill Guides very fascinating to work for. Especially because knowledge and the love for nature are linked to a specific natural area. The guides add value to all the flora, fauna and the landscape described.
Dennis Wansink Board member
Dennis has been part of the Board of Directors since 2012, which he found was a great challende to work on. The Crossbill Guides Foundation was in the middle of a great evolvement to becoming more professional and expanding their possibilities.

Albert Vliegenthart Author
Albert Vliegenthart is one of the authors of the Crossbill nature travel guidebooks. Albert is not only co-author but also assist Dirk in acquisition. Since his childhood he is interested in nature, which resulted in the maximum membership of the NJN (Dutch youth organization for field biology). After studying plant biotechnology in Delft, he started working as a molecular biologist in a private company where research in crop characteristics was only sometimes combined with nature aspects. Meanwhile his passion was kept alive by traveling through Europe exploring nature from North to South. Albert’s most favorite destination is definitely Greece. It may be no surprise that a Crossbill Guide will be an outcome of this enthusiasm. Albert also guides butterfly-tours for SNP (formerly provided by EcoTourist Services), where his knowledge of butterflies, dragonflies, birds and other ecological topics can be shared with fanatic ecotourists. Since 2007, Albert works at the Dutch Butterfly Conservation (De Vlinderstichting) as a project leader. In this job Albert likes the diversity of his work. Protection and habitat management for butterflies and dragonflies as main carriers, using professional scopes, volunteers, databases and the knowledge of DNA: wonderful tools for nature conservation.
Kim Lotterman Author
Kim Lotterman is the principle ecological editor of the guidebooks since the start of the foundation. Together with local experts, he checks the contents of each book thoroughly on its ecological correctness. His credo is 'if I get out of it what I want and my mother still finds it an enjoyable read, it's good'. Kim also writes small sections of the guidebooks. Furthermore he does additional ecological research and is the main ecological consultant for the author, Dirk. He also gets to do the thankful jobs like constructing the long species lists with translations in the back of the books. In daily life Kim is working as a researcher at an ecological nature research and consultancy group called 'Natuurbalans', where he focuses mainly on flora.

He has a broad ecological interest ranging from mosses and lichens to butterflies and birds, but his main interest lies in the flora of the Netherlands and the rest of Europe. The start of nature conservation starts with knowledge about natural areas, their ecology and how these are influenced. Kim values the Crossbill Guides a lot because they inform tourist and local people about these topics. You can enjoy nature so much more when you know why certain things happen or live in an area.
John Cantelo Author

Bouke ten Cate Author
Bouke ten Cate has been an avid nature enthusiast since childhood. He had been enjoying the foundation's guidebooks for years before he became part of the Crossbill Guides author’s team in 2011. Bouke studied Forestry and Nature Management at Van Hall Larenstein University of Applied Sciences in Velp, the Netherlands and has been doing volunteer work for several Dutch NGO's like Birdlife Netherlands, SOVON and RAVON. His fascination with nature began with birds but has spread to the fields of orchids, mammals, reptiles and amphibians. Apart from being a nature enthusiast he also greatly enjoys nature photography, an attribute which comes in very handy when working on a guidebook. Instead of merely directing the reader to the region's rarities, Bouke likes the fact that the guidebooks really explain nature. By showing how environment, climate, flora, fauna and human activity interact. They show the unique circumstances that make the described region so special. This deeper understanding of nature really heightens the visitor's appreciation of the experience. His motto is 'see everything that is to be seen' so exploring Europe's most wonderful natural areas on behalf of the Foundation was something of a dream come true to him.
Kees Woutersen Author
Kees is one of the authors of Crossbill Guides since 2008. From the moment he set eyes on a Crossbill Guide for the first time, with its wide range of nature topics and practical information, he knew that this is what a nature traveler abroad needs to get around. Kees worked as a teacher in economics and as a consultant for small businesses. However he was member of a Dutch youth organization for field biology (CJN) and several bird groups, for many years. Once established in Huesca, at the foothills of the Spanish Pyrenees, he worked professionally with birds and nature. He started his own travel company, organizing nature tours and bird trips all over Spain and publishing several books, e.g. Atlas of the Birds of Huesca (1998). Besides, Kees is active in local bird and nature organizations, organizing and working on education. Kees thinks these books, thorough as well as accessible to a general public, are important to put in value the most important natural areas of Europe. In his opinion, Crossbill Guide activities can convince administrations of different levels to put nature conservation higher on their agendas.

Illustrations & Graphic Design
Horst Wolter Illustrator
Horst Wolter (1977) has been drawing ever since he was able to hold a pencil. When Dirk asked him to make a schematic overview of the habitats of the Biebrza river for the first CGF publication, he immediately said yes. Horst is now the illustrator of the Crossbill Guides foundation. After finishing high school Horst had the choice to either study biology or to go to art school. He chose biology at the University of Nijmegen, where he received his master's degree in 2002. All through his studies Horst kept on creating illustrations of the various aspects of nature, from wildflowers and animals to the intricate patterns organs and cells. His main fascination lies in the complex shapes and structures you can find everywhere in nature and how these all have a purpose or function within 'the bigger scheme of things'. Examining and drawing these often cunning structures (from cell to ecosystem) gives a great insight into 'the why of things'. Within his work for Crossbill Guides Horst brings together his love for nature, fascination for its workings and his qualities as an illustrator.
Chris Braat Illustrator
Chris has been active as an illustrator for the Crossbill Guides since 2006. The first book he worked on was Extremadura 1st edition, but he has worked on many others since. Chris makes the overview illustrations in the front cover and the illustrations of species in region maps. Since he was only 10 years old, Chris has been interested in nature and was often to be found in the dunes of Haarlem. He started his study in Biology at the Wageningen University after which he worked for Natuurmonumenten for many years. In 2008 he became principal of the Free Nature Foundation, who develops areas where nature can develop itself, only influenced by the weather and wild animals. Part of these projects are the use of animals like cattle and horses. For Chris, the Crossbill Guides are more than just a travel guide. Apart from the quality and usefulness for different kind of people (experts and hobby travelers), the Crossbill Guides can really contribute to an area’ economy. The guides help tourists to go to a specific area, which will boost local initiatives.
