When we look at the Willamette Valley, we recognize that we see these remnant giants of Oregon white oak in the landscape. Those Oregon white oaks and the oak savanna have been historically managed with cultural burns since time immemorial.  If we can look at the oak savanna—of which about 3 percent remains today, it's an endangered ecosystem, just like the redwoods or old growth forests—we can see that a lot of our native plant relatives like nettles (Urtica) and the prairies of camas (Camassia) that we are in the process of replanting.

We’re making space for the social and cultural aspects of horticulture as an experience—and we want to honor the role of individual voices. We spoke with a garden futurist who is working to amplify the voices of underrepresented communities in mainstream garden media, specifically the Black community.

Colah B Tawkin is a mother, gardener, and the founder and host of the podcast and media platform known as Black in the Garden. She describes herself as an advocate for Black people trying to reconnect with the land and talks about plants with vigor and volume.

“If you are just an average American, and you’re going about your business spewing carbon into the atmosphere, how many trees do you need to plant a year to offset the amount of carbon that you put in the atmosphere? The answer is somewhere around 80, that need to be planted where trees don’t exist.” – Dr. Matt Ritter

If you take Keystone plants out of your local food web, the food web collapses, because they are producing most of the caterpillars that run that food web. We found that just 5% of our native plant species are supporting 75% of the caterpillars that are out there.

With Dr. Nancy Shackelford, Restoration Futures Lab director, and assistant professor of environmental studies at the University of Victoria British Columbia.

“In this context, restoration has a lot of meanings. One of those meanings is yes, trying to support the plant species, but it’s also trying to rebuild and support those relationships with people and the practices and the traditions and the histories and the cultures that really existed with those ecosystems. And so in this context, restoration really has a very strong human-nature combination and combined values.” Dr. Nancy Shackelford

With Dr. Susan Cordell, Director and Research Ecologist, US Forest Service, Pacific Southwest Research Station, Hilo, Hawai'i.

How might a more culturally inclusive viewpoint replace negative historical language associated with invasive plant biology?

“In many parts of the world, we cannot uncouple the fact that humans and natural systems are linked and that pristine landscapes are often, in fact, a mirage.”  This quote from a paper authored by our guest and colleagues was published recently in Frontiers of Ecology and Evolution. Noticeable right away is that this essay gets very quickly into talking about the language we use when we talk about nature.

Our guest and her multi-disciplinary team have taken a unique approach to ecological restoration that considers language and cultural context around how plants in complex ecosystems can be managed. To learn more about Dr. Cordell's work, please read her group's newest paper, inspired by the Liko Nā Pilina experiment: https://www.hawaii.edu/likonapilina/. This is a project using functional traits to promote invasion resistance and native biodiversity. In this perspective, we teamed up with a philosopher to explore the concept and underlying biases towards non-native species.

“There's a surprising portion of the entire natural world of all biodiversity that either rests in or on an oak tree. And another huge portion of biodiversity uses oak trees for food. An oak can produce 3 million acorns in its lifetime, but only a tiny handful of those, if any,  will create trees, but those extra acorns are there on the ground waiting to feed just a huge number of organisms from tiny ones all the way up to bears.”

One of the most innovative things about botanic gardens remains the incredible diversity of plants in one place. In addition to being centers for horticultural education, botanic gardens can use their living collections—often consisting of thousands of plants—to inform research and conservation.

Our guest today is Dr. Ari Novy, President & CEO at San Diego Botanic Garden, previously Chief Scientist at Leichtag Foundation, and former Executive Director of the U.S. Botanic Garden in Washington, DC

Deborah Pagliaccia’s work has many promising applications, including improving plant and soil health, reducing waste, addressing hunger and food access, reducing water use, and reducing fossil fuel use. Food waste bioproducts, which she calls digestates, are fermented food for plants and other microorganisms. The best part is that gardeners can make it at home!

Dr. Deborah Pagliaccia is a professional researcher in the Department of Microbiology and Plant Pathology, at the University of California, Riverside. She is also the Managing Director of CAFÉ, (California Agriculture and Food Enterprise), a program which supports connections among those interested in food and agriculture on the campus and in the community.
