Dr Gavin Broad: Broadening horizons with Darwin's wasps and other tales of cannibalism, incest and zombies

Trees A Crowd

Show Notes

Dr Gavin Broad’s love of nature was initially inspired by the birdlife of the Wirral. However, the summer lull in avian activity lead the 15-year-old Broad towards an interest in moths, and from there it was only a zombie caterpillar away from the creatures that were to inspire his professional identity and take him as far afield as Chile; Parasitoid wasps! “Darwin Wasps” account for 10% of all British insects - that’s over 7000 distinct wasps - and Broad insists that everyone can easily “admire them, if not like them.” What’s not to like about an insect that can inject its eggs through the bark of a tree and into another insect? Or one that can actively dictate the gender of its offspring to specifically regulate the extant population? Or one that can easily defeat a tarantula?! Quite. David heads to the Natural History Museum to talk Wasps, and to discuss Gavin’s involvement in sequencing the genomes of 70,000 British species - everything from Deep Sea Squid to Pine Marten - his appreciation for the work of Damien Hirst and the similarities it bears to the NHM’s hidden insect archives, and how we would all be far better off if we possessed the curiosity of bored Victorian clergymen.

Recorded live at the Wild Summit, Zack Polanski, leader of the Green Party of England and Wales, sits down with David Oakes to talk about what his "Green Britain" could actually look like. They probe the paradox at the heart of nature access, whether the Green Party's environmental and social-justice instincts really pull in the same direction, and why Zack thinks capping corporate money in politics is a necessary precondition for making our country more full of nature. Along the way: commitments on bottom trawling and grouse moors, the UK's legal target to protect 30% of green and blue spaces by 2030, and a belief that education lies at the heart of all of it. With time running out for the planet, champions of biodiversity are in short supply near the ballot box. Under Zack's leadership, is Britain destined for a Green Party - or just green, partly?

Recorded on the outskirts of Hwange National Park in Zimbabwe, this episode drops David into the high-stakes reality of animal conservation. Guided by Peter Blinston and his team at Painted Dog Conservation, David joins the people whose work keeps Lycaon pictus alive in the buffer zone: Belinda Ncube, PDC’s first female ranger, whose story runs from childhood bush camp to leading a unit of women in a landscape still shaped by patriarchal assumptions; Adraino Sitole, who began as a community volunteer after a Painted dog was killed in a snare just moments from his village, and now tracks poachers with trained sniffer dogs while helping remove thousands of wire traps from the bush; and David Kuvawoga, PDC's Director of Operations, who literally takes Oakes from patrol to rapid response - explaining how the team uses radio alerts and 24/7 tracking to push packs away from snares, highways and other anthropogenic threats, and why, in this context, the low risk of ‘...a habituated wild dog is better than a dead wild dog.’

Around a table at the Woodland Trust's headquarters in Grantham, David sits down with three of the most powerful voices in British conservation: Darren Moorcroft, Chief Executive of the Woodland Trust; Craig Bennett OBE, Chief Executive of The Wildlife Trusts; and Beccy Speight, Chief Executive of the RSPB - between them, custodians of millions of members, thousands of nature reserves, and decades of hard-won environmental progress.

Following on from two episodes recorded on San Cristóbal Island, this episode finds David having set sail across the Galapagos archipelago for Santa Cruz; destination: the headquarters of the Charles Darwin Foundation — the research institution founded alongside the Galápagos National Park, and still at the heart of how science becomes conservation on the islands.

This episode finds David in conversation with the Galápagos-born geographer, Director of Universidad San Francisco de Quito’s Galápagos campus and Co-Director of the Galápagos Science Centre, Professor Carlos F. Mena (recorded with a chorus of barking sea lions providing an unmistakably local backdrop!)
