Dr. Randle comes to us from the U.K. based Butterfly Conservation, one of the largest insect conservation organizations in the world. Dr. Randle points out that artificial light at night affects pheromone production in some female moths and sperm count in some males. Along with all the other environmental pressure, light at night has caused a 32% decline in population since the 1970’s. Thanks to the thousands of volunteers and data sets stretching back decades, you can learn all about them in The Atlas Of Britain & Irelands Larger Moths. Dr. Randle is the ecological lead for Butterfly Conservations’ Big Butterfly Count, an annual UK citizen science survey which helps to assess the health of our environment and connect people to nature. Prior to working for Butterfly Conservation she was a Field Ecologist, working in a range of different habitats, counting and measuring a variety of different plants and animals for scientific research. In her spare time Dr. Randle enjoys riding her horse, photography, star and moon gazing and writing to try to make sense of a crazy world!

Mike comes to us from the North York Moors National Park in the north of England. Mike has done ALOT at the National Park Authority to fight light pollution in the area. He has: helped develop a Dark Skies Festival; encouraged businesses to collaborate and to become Dark Skies Friendly; oversaw the application to become an International Dark Sky Reserve from inception to successful designation and is currently delivering lighting improvement projects across the National Park. Through his work at the Authority, he’s even helped influence the UK government on lighting policy through involvement in a UK Dark Skies Partnership of protected landscapes. He’s now found the time to appear on Restoring Darkness! Mike is Head of Nature Recovery Projects at the North York Moors National Park, a protected upland landscape and International Dark Sky Reserve in the North of England. As well as delivery of landscape scale nature recovery projects within the Conservation and Climate Change Department, Mike is also the lead officer for Dark Skies at the National Park Authority.

Here at Restoring Darkness, we are on a mission to eliminate light pollution. Dr. Barber wants to tackle “sensory pollution.” He is doing that by running the Sensory Ecology Lab at Boise State University and studying the effects of light and sound pollution on birds, bats, and insects. Let’s eliminate light pollution, then we’ll start the “Restoring Silence” podcast! Dr. Barber completed his BS and MS at the University of Wyoming and his PhD at Wake Forest University before he spent 5 years with the National Park Service’s Natural Sounds and Night Skies Division for his postdoctoral work. He now runs the Sensory Ecology Lab at Boise State University – a set of scholars dedicated to understanding how sensory environments and sensory pollution impact birds, bats, and insects.

You’d think a landscape lighting designer wouldn’t really be concerned with sky glow. “Just light up the landscape and the sky be damned!” But you would be wrong if you thought that about Kathryn. Her number one concern when designing is to not add to light pollution. She strongly advises clients to turn off their lights by 10 pm, and even earlier if you aren’t around to enjoy them. She’s a big advocate for controls too, which, as we at Restoring Darkness have been saying, makes sense for outdoor lighting. And Kathryn knows what she’s talking about: She has led workshops and taught classes at numerous locations including universities, and she is an active Mentor Team member of the International Landscape Lighting Institute Intensive Course, and serves on the ILLI Board of Directors and ILLI Programming Committee. Kathryn Toth is an award-winning architectural lighting designer who strives to create artistic lighting solutions. Her projects include exterior, landscape, retail, commercial, and residential projects around the globe. Working to create the visual atmosphere and enhance the space is her specialty. Kathryn is an active and instrumental member of the Illuminating Engineering Society (IES) Recommended Practice for Landscape Lighting and the IES Outdoor Nighttime Environments (ONE) committees, a member of the International Dark-Sky Association (IDA), and a board member of the International Landscape Lighting Institute (ILLI).

Sometimes it’s a good idea to go to the source. So we went to the founder of the Responsible Outdoor Light At Night conference (ROLAN), Karolina Zielińska-Dąbkowska. Karolina explains to Michael and John that as a lighting designer, she had questions that she couldn’t find answers to. And researchers wouldn’t let her in because she wasn’t in their circle. So Karolina went out and got her own PhD and became a researcher. Thankfully she’s willing to share some of her research with us. Dr. Karolina M. Zielinska-Dabkowska IALD, IES, CIE, MSLL, RIBA is an architect and an award winning practicing lighting designer with over 20 years of experience working in the field of lighting design. Karolina is also an Assistant Professor at the Faculty of Architecture, Gdansk University of Technology, Poland, and Co-Founder of GUT LightLab, where she conducts research on various aspects of light and lighting in the built environment. In 2022 Karolina Founded Responsible Outdoor Lighting at Night (ROLAN) conference and was principal co-author of the ROLAN Manifesto.

If you ever doubted the impact on wildlife of humans just being around, let Sheldon tell you how the turtle nests in Hawaii bounced back in 2020. Luckily that trend continues with her army of volunteers that help redirect hatchlings away from artificial lights that lead them away from the water. Michael and John also discuss with Sheldon how there are light pollution ordinances in almost every city and town but no enforcement. Dr. Sheldon Plentovich leads the US Fish and Wildlife Services’ Pacific Islands Coastal Program where she works with partners to find innovative ways to protect and restore island ecosystems. She grew up in the southeastern United States and started working on Pacific Islands in 1996. Her priorities are community-based restoration efforts, ecosystem restoration at a landscape scale and species translocations. When she’s not working, she’s surfing, mountain biking or spoiling her dogs.

We all know cities are a big contributor to light pollution. Charlotte Gage from Adfree Cities in the United Kingdom, contends that one of the biggest offenders is digital advertising. LED’s are getting brighter and advertising signs are being left on all night, drowning out views of the night sky but also destroying people’s sleep who live nearby these signs. Charlotte, Michael and John discuss what progress has been made, about how laws haven’t caught up to digital signage, and how best to tackle this blight. Charlotte Gage is Network Director for Adfree Cities, a network of groups across the UK who are concerned about the impacts of corporate advertising on our health, wellbeing, environment, climate, communities and the local economy. Adfree Cities lobby for policy change at national and local levels, showcase alternatives, organize locally to stop new advertising sites in UK cities, and produce resources to raise awareness about the impacts of commercial advertising.
