20: Back garden biodiversity: 9,600

Recorded at the RHS Chelsea Flower Show, Alice and Sue explore the vital role our gardens play in supporting wildlife and how we can help shape these thriving mini ecosystems. At the UKCEH Nature Decoded exhibit, they meet UKCEH data scientist Alyssa Duffy, who introduces the innovative biodiversity‑monitoring technologies on display — from soil and freshwater acoustic sensors to the LepiSense, affectionately known as the “moth photo booth”. They also speak with UKCEH ecologist Dr Michael Pocock about how anyone can contribute to science by recording the wildlife in their gardens using apps like iRecord, and the wellbeing benefits that come from taking part. The Big British Garden Survey, a collaboration between UKCEH and the National Garden Scheme, offers another way for people to help build a richer picture of the wildlife around us. Dr Richard Claxton, Chief Executive of the National Garden Scheme, shares more about this survey and the importance of taking part.

19: Unpacking Oil Palm: 80 million

From chocolate and shampoo to food, palm oil can be found in a range of packaged goods on the supermarket shelves and is used throughout industry. Its versatility makes it difficult to replace yet its production remains controversial due to high greenhouse gas emissions, the extensive deforestation carried out in Southeast Asia in the 1990s to make way for oil palm plantations, and habitat loss for a range of endangered species.  So how can the oil palm industry become more sustainable? In this episode Alice Hope and Sue Nelson visit the Royal Botanic Gardens, Kew [https://www.kew.org/] to meet palm house manager Will Spoelstra, who offers insight into the plant.      UKCEH scientists Dr Julia Drewer and Professor Niall McNamara share insights from their research in Malaysia to improve soil quality and reduce greenhouse gas emissions. Plus Sue and Alice hear from the Malaysian partners in that research – Dr Reza Azmi from the Social Enterprise Wild Asia [https://www.wildasia.org/] - about how this trial is helping small-scale producers adopt more sustainable practices to support livelihoods and the environment. Finally the conversation shifts to Africa, where the oil palm originated from, as Dr Nick Cowan explains how lessons learned in Asia are being applied to new regions.

18: Whiplash weather: 90

Let’s talk drought. Yes, that’s right, drought! Our weather is experiencing extremes - from flooding to drought - so Alice and Sue delve into this whiplash weather with UKCEH senior hydrologist Lucy Barker. With the latest Hydrological Summary showing that January has been much wetter than average, they explore whether that is enough to replenish water reserves following the extended drought in 2025. Alice and Sue also catch up with UKCEH micro-meteorologist Dr Jon Evans at a COSMOS-UK field site at Chimney Meadows Nature Reserve in Oxfordshire, one of 39 sites which make up a national soil moisture monitoring network that’s literally out of this world. Soil moisture is just one measure alongside rainfall, river flows, groundwater data that UKCEH gathers in partnership with others to produce monthly hydrological summaries – an essential tool for environmental regulators, government agencies, water companies, researchers and farmers.  Hosts: Sue Nelson and Alice Hope Producer: Rachael Buchanan Counting the Earth is a Boffin Media Production for the UK Centre for Ecology & Hydrology.

17: The Burning Issue: 3.7 million

Wildfires are evolving. Around the world they are becoming bigger, burning hotter, and harder to control with devastating impacts on humans, the economy and the environment. In this episode, Alice and Sue talk to UKCEH wildfire scientist Dr Douglas Kelley who outlines the causes of this change, drawing on examples from California and the Pantanal, the worlds’ largest tropical wetland.   Closer to home, it has been a record year for wildfires in the UK. Alice catches up with Station Commander and Wildfire Tactical Adviser Andy Elliott from Dorset and Wiltshire Fire and Rescue Service. They visit Holt Heath National Nature Reserve in Dorset, the site of a fierce large scale blaze in August. Andy reveals that, due to the fire’s intensity, the lowland heath landscape may take up to 30 years to recover.    Hosts: Sue Nelson and Alice Hope Producer: Rachael Buchanan Counting the Earth is a Boffin Media Production for the UK Centre for Ecology & Hydrology.

16: Encounters of the Invasive Kind: 2,104

What do raccoons, purple pitcher plants, signal crayfish and the yellow-legged hornet all have in common? No, this is not a joke - far from it. They are all on the GB invasive non-native species alert list. The introduction of invasive non-native species is one of the top causes of biodiversity loss worldwide. In this episode Sue and Alice meet up with UKCEH ecologist Professor Helen Roy to delve into the challenges posed by invasive non-native species and explore their environmental, economic, and social impacts. They also catch up with Dr Olaf Booy, Technical Coordinator for the GB Non-native Species Secretariat, part of the Animal and Plant Health Agency, to find out about the work that goes on to identify, detect, monitor and eradicate invasive non-native species. Olaf also spoke about how events such Invasive Species Week (12-18 May) help to raise awareness of the issue and what you can do to help and get involved.
