Thursday 9th November:A biodiverse city 6:45 p.m. in the David Attenborough Building and online Guy Belcher, Biodiversity Officer for Cambridge City Council, will talk about the City’s Biodiversity Strategy.
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.
Thursday 30th November: How the Andes influence Earth’s climate 7:30 p.m. online Morag Hunter will talk about the interaction between the uplift of the Andes and carbon dioxide budgets in the atmosphere. She will describe the geology and outline the chemical weathering of the rocks found in the Cañete Basin, western Peru.

People power for nature: the challenges and the opportunities
Peter Exley has worked for the RSPB, for over 25 years, on building peoples’ support for nature, from campaigns to communities. He is currently involved in making the charity’s 170 nature reserves more visitable. In his talk he will look at the barriers, issues and opportunities, and why understanding people is essential to saving nature, using examples of projects he has worked on, from saving seabirds on islands to creating new nature reserves in the Somerset Levels.
Online via Zoom. Members will be emailed login details nearer the time.

We have been sent information about an Earthwatch Europe event at the Five Trees Tiny Forest in Chesterton. It’s on Friday 11th August, from 1 p.m. to 4 p.m. and the organisers say “We will be counting bugs and butterflies, measuring trees and enjoying being among the young saplings! The data collected will feed into future understandings of urban tree planting and re-forestation, ensuring best practice is rooted in science.”
On Saturday 8 th July, the National Trust are having a Bioblitz at White Fen, just north of Anglesey Abbey.
“The idea behind a BioBlitz is for wildlife experts and the wider public to work together to find and identify in the area as many species of plants and animals as possible. The records collected during a BioBlitz form part of a genuine scientific survey of the area. The event is an informal and fun way for young people and other members of the public to learn alongside experts and share and develop their enthusiasm for nature.”
From 8.00am – 4.00pm they will finding and recording wildlife with local experts and the wider public.
Activities timetable: 8am Moth and small mammal traps open. 10am Bird/Birdsong Walk 11:30am Dragonfly Walk 2pm Plants/Wildflower Walk
Access instructions (provided by the National Trust)

The spring programme continues on Thursday 16th February with a talk by Joshua Pike: Reconstructing past abrupt climate change in Patagonia.

The CNHS programme of talks this spring will start on Thursday 2nd February with a talk by Mike Maunder, which will take place at 6:45 pm in the Lecture Theatre in the Department of Geography on the Downing Site. The talk will also be available online for those unable to attend in person. The link will be emailed to those on the CNHS mailing list.
The talk is entitled 500 years of exhibiting biodiversity: from cabinets of curiosity to interpreting today’s extinction crisis. In it he will explore how today’s biodiversity exhibits (museums, aquaria, botanic gardens and zoos) have evolved over the last 500 years and how they are responding to fundamental challenge of the collapse of nature. The lecture is based on Mike’s previous work as a conservationist working with institutions exhibiting biodiversity and his research for a book on this topic. As a society we are still drawn to the exotic composition and super abundance of biodiversity exhibits, yet those exhibitions are in a constant evolution as their scientific, business, ethical and cultural context is in constant flux.
The Department of Geography is easily reached from Downing Place. Click here for a map (in a new window) of the Downing Site showing the location. Parking is not available on the Downing Site.
