Kate Bellingham joined museum entomologist Max Barclay. He has a record of 200,000 insects collected on Bookham Common over the last 120 years. Bookham Common provides an almost complete picture of how life responds to everything from extinction to climate change. Although this common has been studied in great detail, there's one place Max has never been able to look, the treetop canopy. Nobody has really looked at what's in the canopy of oak forests in southern England, and our experiments in the tropics have shown that an enormous amount of biodiversity lives in the canopy of the tree. Even though it's only one species, this is just a single oak tree. Oak is one of the richest and most diverse trees in terms of number of species, and there're hundreds of species of insect associated entirely with oak trees.


凯特与馆中昆虫学家麦克斯·巴克莱会师，据他手头记录，过去120年中，在布氏生物区共收集到二十万种昆虫。这一生物区提供了完备的研究标本，展现了生物对外界环境的反应。从物种灭绝，到气候变化，尽管此地已被研究得非常细致。有一个地方，麦克斯却从未得见，树冠的顶部，从没有人真正看到过南英格兰橡树林的树冠顶部，在热带地区进行的实验已经表明，树冠顶部的生物群极富多样性，即使只在这棵树上。这是一棵橡树，就物种数量来说，橡树的种类非常多，有数百种昆虫，只生存在橡树上。
