Dr Jon Bennie delivered the #esiChallengeOfTheMonth (hybrid) talk "Shifting grounds: rethinking conservation in an age of rapid climate change" in the ESI Trevithick Room on Monday 24 November 1.30 - 2.30pm.

At the turn of the 21st Century, ecologists estimated that between 15 and 37% of species will be ‘committed to extinction’ by 2050 due to climate change, if urgent action was not taken to curb greenhouse gas emissions. This represents a major acceleration of the biodiversity crisis, compounding ongoing losses due to resource exploitation and land use change. In 2025 we are now halfway through the timescale of those predictions, and there is indeed mounting evidence that as species change their distributions to track a changing climate, local extinctions are occurring, new species arriving, and novel ecosystems are developing. These processes challenge existing conservation paradigms which are often strongly based in a sense of place – we put special value on native species and ecosystems, traditional cultural landscapes and human values and attachments to familiar environments. As efforts to curtail emissions fall short of the action required to stabilise global temperatures below 1.5 degrees (and likely 2 degrees), I review what we understand about the ecological changes that are occurring, and ask how we might deal with understanding and managing environmental change and loss. This is a talk in two halves – in the first I will describe research on how species and ecosystems are predicted to respond to climate change and the evidence for these changes. In the second I will describe some recent work with the Adaptive Heritage Practice Lab (AHPL) collective exploring how in a rapidly changing world, conservation practices might become more flexible and responsive to changing conditions.
