Vital reading for all those interested in the conservation of the world's most important ecosystem. In a lucid style backed by encyclopaedic knowledge, Killeen unpicks the extremely complex ecological and socio-political threads that comprise the recent history and the vital future of the Pan Amazon region. The fight to save the Amazon is a fight for sustainability that is emblematic of the entire future of human co-existence with Nature on Earth. Killeen is an authoritative and impassioned guide, eschewing soundbites in favour of a clearsighted and highly nuanced picture of the realities on the ground. Only in understanding present realities and how they came to pass, he argues, can we proceed hopefully into the future. Events of the last ten years are discussed in detail, because future events will have to build upon – or modify – the cultural and economic forces driving events in the Pan Amazon. Nonetheless, the text provides a longer historical perspective to show how policies create legacies that reverberate over decades, long after they have been recognised as being fundamentally flawed.

This paper is the result of the work of hundreds of different scientists and research institutions in the Amazon over the past 80 years. Without their hard work this analysis would have been impossible. We thank Charles Zartman for the use of plots from Jutai.

The Amacayacu Forest Dynamics Plot is part of the Center for Tropical Forest Science, a global network of large-scale demographic tree plots. We acknowledge the Director and staff of the Amacayacu National Park for supporting and maintaining the project in this National Park. ; Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia is best approximated by a logseries with aggregated individuals, where aggregation increases with rarity. By averaging several methods to estimate total richness, we confirm that over 15,000 tree species are expected to occur in Amazonia. We also show that using ten times the number of plots would result in an increase to just ~50% of those 15,000 estimated species. To get a more complete sample of all tree species, rigorous field campaigns may be needed but the number of trees in Amazonia will remain an estimate for years to come. ; Publisher PDF ; Peer reviewed
