Micropaleontologist Dr Francine McCarthy goes deep into the sediments of Crawford Lake, a small and unassuming lake in the Niagara Escarpment town of Milton, Ontario. In 2023, Dr McCarthy led a team that identified Crawford Lake as the best location on earth that captured evidence of human caused planetary change. Endorsed by the Anthropocene Working Group, It was proposed as the best ‘golden spike’ site of the Anthropocene. Dr McCarthy shares how she first encountered the lake, her research on microscopic organisms of the Great Lakes Region, and personal reflections on the Anthropocene.

Bio:

Dr Francine McCarthy is a professor of Earth Sciences at Brock University in St. Catharines, Ontario. She is a micropaleontologist who reconstructs paleoenvironments through careful analysis of small organisms fossilized in lake sediments. Her research has spanned small lake to marine environments and everything in between. She has worked around the world but primarily focuses in the Great Lakes Region of Canada. Her interdisciplinary research has been conducted in collaboration with several geologists, biologists, geographers, and archaeologists from government, university, and the private sector.

Forest ecologist Jen Sanger spends more time in big trees than most. In our conversation, she takes us into another world of canopy of Australia’s tallest trees and into Tasmania’s aptly named Grove of Giants. She shares the story of the evolution of the distinctive Tasmanian flora, the ecology of these special forests and  the summer she helped get 500 community members nearly 100m up into the canopy.

Bio:

Dr Jennifer Sanger is the co-founder for The Tree Projects, a Tasmanian based an environmental outreach organisation which educates people about the worlds most notable trees. She is a passionate forest ecologist and has spent over a decade studying forests and the charismatic plants that inhabit them. She is both an expert tree climber and communicator and passionate advocate for Tasmanian forests.

Partners in life and work, herbalist Deatra Cohen and reference librarian and researcher Adam Siegel are the authors of the incredible resource Ashkenazi Herbalism. Together they spent years researching little known texts, translating ethnobotanical surveys and cross-referencing cultural databases to unearth lost Ashkenazi plant practices from the pale of settlement region. They share the stories and traditions of a few of their favourite plants along with Deatra’s own journey to plant healing work.

Bio:

Deatra Cohen is a former reference librarian and herbalist who trained with the Berkeley Herbal Center. She also belongs to a clinical herbal collective and is a Master Gardener at the University of California.

Adam Siegel is a research librarian at the University of California, Davis, and a historian of Central and eastern Europe, studying issues around cultural contact and plant knowledge in the region. Adam is also a literary translator, focusing on works in Russian, Czech, German, Croatian, Serbian, French, Italian, Swedish, and Norwegian. In 2014, he was awarded a Literary Translation Fellowship from the National Endowment for the Arts.

Tennessee-based artist Ripley Whiteside creates art as a way to explore and connect to nature, history and speculative ecological futures. In a wide-ranging conversation spanning, contemporary ecological thought, invasive species and an ancient Medieval text—the Augsburg Book of Miracles—the conversation looks at the mysterious constructs of our understanding of nature. His place-based work is inspired by time spent Montreal, North Carolina and his home in Tennessee.

Bio:

Ripley Whiteside was born in 1982 and grew up in Chapel Hill, North Carolina. In 2012 he graduated with an MFA from SUNY-Buffalo, and he received a BFA from University of North Carolina, Chapel Hill in 2008.

Urban ecologist Manuel Esperon-Rodriguez in conversation with Catherine Polcz. 

He shares his journey from researching plant physiology in the Mexican Veracruz Montane Forests to future-proofing diverse urban forests of Western Sydney. His work is driven by understanding our relationship to the urban environment where people and plants are reliant on one another.

Bio:

Manuel Esperon-Rodriguez is a Sydney-based, Mexican ecologist who studies the effects of climate on plant function in urban ecosystems. He completed his PhD in Eastern Mexico assessing the vulnerability of the lush Veracruz cloud forest to climate change. In 2015 he joined Macquarie University with a project identifying climate refugia and plant migration corridors in Australia. In 2017 he joined the Hawkesbury Institute for the Environment at Western Sydney University where he continues his research on urban forests.

Plant Kingdom is a conversation series about plants, nature and environment featuring scientists, artists, researchers, writers and healers.

We release two conversations each month, and hear form people who have an intimacy with plants and nature. We discuss their work, stories and reflections from the field.

We record in Sydney, Australia on the lands of the Gadigal people of the Eora nation, and pay respect to their elders - past, present and future.
