The Madrean Sky Islands are a series of 57 isolated mountains that run from Arizona and New Mexico to Northern Mexico. Each mountain sits in the hot and arid desert of the surrounding lowlands, their tops adorned with pine-oak forests. This unique landscape makes this region home to one of the most biologically diverse regions of the world, a region Greater Good Charities aims to explore, observe and protect.

Our Madrean Discovery Expeditions program brings multinational scientists, photographers, enthusiasts and students together to study the plants and animals of this incredible region. This information is then stored in an open-source database for the world to share, study and use to preserve these ecosystems forever.
This important work can only happen with your help. Your gift will allow more work to be done, more records to be collected, and ultimately, more plants and animals protected.
