Long-term ecological sites: musings on the future, as seen (dimly) from the past

Long-term ecological sites are 'listening places' - places where we press our ears to the earth and strain to hear its pulse. Such sites will be needed especially in coming decades, as ecosystems throughout the world face mounting stresses, mostly from human influences. My aim, in these musings, is to elicit conversation, by way of seven questions, about how best to look after the long-term sites, so that they remain intact, relevant, and enlightening for our successors, decades hence.
