Summary

Edge of range dynamics are always fascinating. Range edges present lots of unique challenges for which plants must contend. When you throw humans into the mix, those challenges often become far more extreme. Join me and plant ecologist Sara Johnson as we look at a system involving hydrology, road salt, and the ever charismatic white cedar or arborvitae (Thuja occidentalis). This episode was produced in part by Corbin, Keena, Robin, Peter, Whitney, Kenned, Margaret, Daniel, Karen, David, Earl, Jocelyn, Gary, Krysta, Elizabeth, Southern California Carnivorous Plant Enthusiasts, Pattypollinators, Peter, Judson, Ella, Alex, Dan, Pamela, Peter, Andrea, Nathan, Karyn, Michelle, Jillian, Chellie, Linda, Laura, Miz Holly, Christie, Carlos, Paleo Fern, Levi, Sylvia, Lanny, Ben, Lily, Craig, Sarah, Lor, Monika, Brandon, Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

0:00.0	Hello everyone and welcome to the indefensea plants podcast, the official podcast of indefenseaplants.com.
0:05.7	What's up? This is your host Matt. Welcome to the show. How is everyone doing this week?
0:10.5	In this episode, we're going to be talking about a species many of you will probably be familiar with.
0:15.7	Thuja, Oxid, and Talus, or the white cedar, sometimes called the Arbor Vidy.
0:21.0	Now this is a horticultural celebrity, so to speak. It is widespread in cultivation,
0:25.8	but in the wild, stories a little bit different, especially along the edge of its range.
0:30.9	Joining us to talk about this is Sarah Johnson. A voice you've probably heard on this podcast in the
0:35.1	past. She is a conservation ecologist with a strong focus in botany and a very talented and
0:40.6	passionate person at that. And she's going to talk to us about some really cool work that she's
0:45.1	done on Thuja populations along the edge of the range in the greater Chicago region. I don't want
0:50.7	to steal any of her thunder, so let's just jump right into it without further ado. Here's my conversation.
0:55.8	Sarah Johnson, I hope you enjoy.
1:12.0	All right, Sarah Johnson. Welcome back to the podcast. Now for everyone listening,
1:16.9	if you supported the show through Patreon, this is a voice you'd be hearing a lot more of.
1:21.5	But today for those that don't support the Patreon yet, or have not listened to previous episodes,
1:27.3	let's start with an introduction. Tell us a little bit about who you are and what it is you do.
1:32.3	Hi, my name is Sarah Johnson, and I'm a plant ecologist with the Illinois Natural History Survey,
1:39.8	which is a research institute within the University of Illinois or Banish campaign.
1:45.2	That's awesome. And so the latest episode that you were on, we talked about some of the work you
1:51.4	did for your master's research on McBridey Alba. And today we're talking about some other interesting,
1:57.4	fascinating realms that you have sort of ventured into throughout the years and really kind of looking
2:04.3	at plants from more of an ecosystem, human impacts sort of perspective. So welcome back. Happy to
	...
