Thursday 16th November: Fieldwork: A Dendrochronologist’s
perspective on Science, Life, and Adventure
7:30 p.m. online
Paul Krusic will speak on the challenges of finding trees that have not been disturbed by humans, from which a pristine record of environmental change is captured in the annual variations of tree growth. Where do such forests exist and what does it take to get there? These forests are where he does his research, from the Himalaya to the
Tropics, using dendrochronology to learn more about environmental history and how it relates to climate change.

Thursday 23rd November: The life of the Cam: In sickness and in health
6:45 p.m. in the David Attenborough Building and online
Stephen Tomkins, from the Cam Valley Forum, will talk about what he has learned from trying to help improve our local river. Over abstraction and other changes have been harmful – we have a very sick river: abused by our own un-natural history. Wetland wildlife has a huge capacity to bounce back from near extinction, but that requires much more of all of us to help it improve.
