Epiphyte and tree canopy researcher, Ivan Diaz, ascending to the canopy of a Nothofagus Betuloides forest (Megallanic beech) on Cape Horn Island (Isla Hornos). He collects samples of Epiphytes at different heights from the trunk and measures the tree height. In this area, on the slopes of a hill, the trees are significantly taller, most likely due to the less exposed conditions, than the island's southernmost tree which is less than one metre in height. The tallest measured by Ivan was 10 metres.<br />

Scientist and leader of the expedition, Brian Buma, says: ''The overall purpose is to get a sense of the forest diversity on the island. The structural diversity of a forest is really what gives it a lot of its biodiversity, because it creates so many microhabitats - tall trees have lots of light on the top (at the canopy), low light at the bottom, and a variety in the middle. This makes for a variety of habitats for epiphytes and other tree-dependent organisms. So the southernmost forests, as they grow, should get more structurally diverse. It was great to find a fully mature forest in some sheltered spots as that gives us a sense of potential, the diversity on the remote island (nobody has climbed there before to find what Ivan was finding!), potentially totally new stuff, and then what could happen down there in the future as they grow.''
