Every spring, something remarkable happens in the tidal waters of Black Creek in Esopus, New York: tiny, translucent eels — just an inch and a half long and barely the weight of a postage stamp — swim in from the Atlantic Ocean, following a journey that began in the Sargasso Sea nearly a year before. In this episode, guest host Sierra DeVito joins the Hudson River Eel Project at Black Creek Preserve, where Professor Susan Hereth of SUNY New Paltz leads a team of college and high school studen...

After nearly 30 years wading Catskill streams, Dany Davis has learned that rivers don't just carry water — they carry time, memory, and if you're paying close enough attention, a few life lessons too. Now retiring as Stream Studies Coordinator for the NYC Department of Environmental Protection, Dany is heading home to Alaska, and he sat down with us to reflect on what the streams gave back. On the banks of Warner Creek in Chichester, the conversation turns to geology, glaciers, and the surpri...

Prescribed Fire in the Catskills: Restoring a Lost Tool In this episode, Brett sits down once again with Ryan Trapani, Director of Forest Services at the Catskill Forest Association, to explore the surprising ecological value of prescribed fire in the Northeast. Recorded fireside at the Kaatscast studio, this conversation digs into the science, history, and cultural memory of fire in the Catskills, and why small, carefully managed burns may be key to healthier forests, richer wildlife habitat...

Measuring Snow: Citizen Science in the Catskills Summary: Winter in the Catskills isn’t just about skiing, sledding, or shoveling. Snowpack plays a critical role in our water resources, local economies, and even global climate regulation. In this episode, Brett Barry speaks with Dr. Marco Tedesco of Columbia University’s Lamont‑Doherty Earth Observatory, about the NASA‑funded X‑Snow Project — a citizen science initiative inviting volunteers to measure, photograph, and collect snow data across th...

Did you know the Catskill region was once tropical—and south of the equator?! In this episode, Brett Barry visits the Gilboa Museum and Juried History Center to explore one of the oldest fossilized forests on Earth. Education Chair Kristen Wyckoff shares her decades-long passion for paleobotany, the story behind Gilboa’s world-famous Devonian tree stumps, and discoveries unearthed during the Schoharie Reservoir construction, dam restoration, and creek bed fossil hunts. From lungfish and sea s...

Is leaving the woods alone really the best way to preserve them? According to forester Ryan Trapani of the Catskill Forest Association, “doing nothing” comes with hidden costs—and a whole lot of shade-loving trees. In this immersive forest consultation, Ryan pays a visit to host Brett Barry's property to explore hands-on stewardship, the limits of laissez-faire ecology, and the surprising power of sunlight in shaping forest health. In this episode: How to spot hazard trees before they fall (...

Kaatscast spoke with Cornell University researchers about their latest investigations into New York State bobcat population abundance and the discovery of avian influenza (bird flu) in these wild felines. Featuring Jenny Bloodgood, a wildlife veterinarian, and Haley Turner, a Cornell graduate student, the podcast explores their collaborative efforts to assess bobcat abundance and health using GPS collar tagging and camera trap stations. The discussion highlights various diseases affecting bob...

Exploring the Magical World of Mushrooms with Catskill Fungi's John Michelotti In this episode of Kaatscast, host Brett Barry interviews John Michelotti, mushroom maven and founder of Catskill Fungi. John draws listeners into the enchanting and complex world of fungi, sharing his journey from an outdoor guide to becoming an enthusiastic mycology educator. Recorded at Catskill Fungi's commercial kitchen in Pine Hill, the episode delves into the life cycle of mushrooms, their ecological roles, ...

In a new effort to enhance communications in the Catskills, the New York City Department of Environmental Protection (DEP) is partnering with New York's ConnectALL initiative to expand wireless and broadband access throughout the New York City watershed. The initiative was motivated by operational challenges faced by DEP staff due to poor cell coverage, and a recent Request for Information (RFI) seeks input from telecommunications providers and other stakeholders on how to eliminate cell phon...

Unveiling the Mysteries of the North American Porcupine In this episode of 'Kaatscast,' host Brett Barry delves into the fascinating world of the North American porcupine with Uldis Roze, the world's foremost expert on this mysterious and lovable Catskills rodent. Hear about the porcupine's habitat preferences, diet, mating behaviors, and unique defense mechanisms. Roze addresses common misconceptions, shares personal encounters, and reveals insights from his decades-long research, including ...

Michael Kudish is a Catskills legend and the authority on Catskills trees and forests. In 1971, Kudish earned his PhD with the thesis, "Vegetational History of the Catskill High Peaks." Five decades later, that research is ongoing. In 2000, Purple Mountain Press published his landmark book, The Catskill Forest: A History. Now, an updated 6-volume set is in the works. I met up with Michael at his home/research library in Delaware County, to hear about his latest research sampling Catskills bog...

In 2022, four Master Gardeners were looking for a new way to bring their expertise to our region, and they did so with a weekly podcast on everything from honeybees to hydrangeas; perennials and pollinators; monarchs, chickens, seeds, goats, and houseplants. Nature Calls: Conversations from the Hudson Valley is a production of Cornell Cooperative Extension, Columbia and Greene Counties. And speaking of Cornell, the seed for this podcast was planted in the midst of the American Civil War. T...

Spring has sprung in the Catskills, and with the reemergence of our native flora and fauna, invasive species are also happy to awaken. Catskill Regional Invasive Species Partnership (CRISP) director John Thompson tells us what to watch out for, how to report our findings, and what we can do to stem the tide of invasive pests. Plus, two emerging invasives to add to our radar! Report your findings at: https://www.imapinvasives.org/ Thanks to our sponsors: Briars & Brambles Books, Hanford Mil...

If a tick bites you in the woods, and it's free of disease-causing pathogens, does it matter? We wanted to know how many of our Catskills ticks are pathogenetic, so we sent 6 of them to the Thangamani Lab at Upstate Medical University, in Syracuse, NY. You, too, can send any New York tick, and Dr. Thangamani and his team will test it (for free!) for Lyme disease-causing bacteria, and 16 additional pathogens. It's all part of a massive citizen science research initiative tracking distribution of ...

Feeling sleepy? CO2 could be the culprit. For centuries, the Catskills have offered a respite from city life, and a bit of fresh air. But indoor air quality can be bad no matter where you live. Fortunately, air quality can be measured, and steps taken to get that indoor Catskills air more in line with outdoor Catskills air, for health and wellness. For more, we connected with IAQ expert Ljeta Putāne and local citizen scientist Liz Potter. Thanks to our sponsors: The Mountain Eagle, and the Catsk...

This week: bees! wasps! hornets! yellowjackets! (and other things that sting) with special guest Justin O. Schmidt, research biologist at Southwestern Biological Institute, adjunct faculty at University of Arizona’s department of entymology, author of The Sting of the Wild, and creator of the famous Schmidt Sting Pain Index. Scientific American called Schmidt the "King of Sting." The New York Times dubbed him a “Connoisseur of Pain.” Here’s your college class on stings, with ... if we may ... th...
