Built by South Africans who love South Africa’s trees
Search. Discover. Treasure
Decades of botanical knowledge, artistic skill, digital savvy and conservation passion
— brought together in one proudly South African app.
We are so grateful to all the amazing people who make TheTreeApp possible: from botanists and illustrators to developers, digital gurus, academics, researchers, photographers, landscapers, tree enthusiasts and support teams. TheTreeApp is the result of passion, expertise and countless hours of dedication.
Botanical accuracy and integrity are at the heart of everything we do, and we couldn’t have done it without the incredible people behind the scenes.

AAGE V. Jensen Charity Foundation
The conservation initiative and launch of the TheTreeApp in 2017 was endorsed and
supported by the AAGE V. Jensen Charity Foundation
The objective of the Aage V. Jensen Charity Foundation is nature conservation and wildlife protection.
The Foundation operates worldwide via ownership of nature reserves as well as support of research and nature projects. The Foundation is committed to preserving, protecting and developing nature in all its diversity. The aim is to communicate the importance of protecting endangered wildlife and natural habitats, and to give the general public the opportunity to experience a rich and diverse nature – now and forever.
Since 1999 the Foundation has owned and developed a 38,000 ha nature reserve in South Africa, Maremani Nature Reserve, with the purpose of restoring nature and wildlife to its original and pristine state.
Every tree you explore in TheTreeApp reflects the care, knowledge, and creativity of hundreds of contributors.
This app is the culmination of decades of work from scientists, artists, educators, and conservationists. Thank you to everyone — past and present — who helped us bring South Africa’s trees closer to the hearts of its people
