An aerial shot of the Sts’ailes forest garden. These forests demonstrate the way that First Nations people in the Pacific Northwest have actively managed natural ecosystems to increase the accessibility of preferred food near their homes.
Today’s story is about how indigenous people in Canada have created “forest gardens” to be able to harvest the traditional food the tribes value.
From the radio show Living on Earth:
“BOBBY BASCOMB: British Columbia is home to lush forests that cover almost two-thirds of the Canadian province. And for some ten thousand years, First Nations peoples made the forests their home. The trees provided much of what the people needed to survive and thrive. After asking permission of towering cedars, Coast Salish and other peoples would harvest bark for weaving and wood to carve canoes and totem poles. But they also carved out special gardens in the forest to grow food and medicinal plants. And new research shows that these forest gardens are still home to abundant biodiversity. …
“DR. CHELSEY GERALDA ARMSTRONG: We live in the Pacific Northwest where you have very contiguous conifer dominant forests … cedar and spruce and hemlock and firs. [But the forest gardens are] broadleaf forests, which are very rare here … maple and birch and then sub canopies of hazelnut and crabapple, all deciduous species. One of the big things that kind of sticks out when you’re in these places is at the right time of year, it’s just like a fruit paradise. There’s so many fruits going, kind of around late August, early September. It is an edible forest without question, and also a lot of medicinal species as well in that understory, things like wild ginger. …
“BASCOMB: And these were gardens cultivated by the Indigenous people that lived there, how did they create them? It sounds like they must have had to travel quite far to bring these different species together in one spot. …
“ARMSTRONG: We don’t know exactly how they were started, or when, how old they are, although we are getting closer to some dates. … Hazelnut, for example, [is] a native species to British Columbia, but it’s found far outside its range in certain forest gardens. But also, people were managing for succession. These types of forest management practices are basically utilizing and capitalizing on natural ecosystem processes. So things like wild raspberries, black huckleberries, Alaska blueberry, oval-leaf blueberry, all these kinds of plants that grow in forest gardens are locally available. And so it’s just about letting those things come back, keeping the competitors out, and then enhancing them with new species. …
“ARMSTRONG: Comparing forest gardens with the surrounding conifer forests, or what we refer to as peripheral forest, it was very clear that overall, forest gardens [were] a lot more biodiverse. … So you can imagine that, in fact, the edge between these two ecosystems are incredibly productive areas.
“BASCOMB: Well, that totally makes sense. I mean, you would expect more biodiversity in an area with, say, maybe a field, next to a forest, with a river running through it. If you have several different ecosystems all in one spot. ….
“ARMSTRONG: We found that forest gardens have a higher frequency of animal-dispersed and animal-pollinated species. So what this means is that forest gardens are the result of animal movement. And of course, humans are included in that category. But on top of that, what this suggests is that after humans left these gardens and villages, in some cases a couple hundred years ago, forest gardens began providing really unique habitat for animals and pollinators seeking food. So what we see here is an example of human land use that actually provides and increases functions across the landscape, rather than depleting it. …
“BASCOMB: Can you tell me about the First Nations people that lived in this area and created these gardens? …
“ARMSTRONG: I worked with two communities, Kitsumkalum, and Kitselas. And, you know, the archaeological record of people living in this area is very, very rich. People have been here for, you know, 10,000 plus years. And for Kitselas, we know that [families] have been in the same canyon area for at least 7,000 years. [But] people were forcibly removed from their communities. A lot of times they moved to the coast to work in canneries, which were, you know, kind of slave-like conditions for people. But they returned, a lot of them, to their communities in the ’50s and ’60s. …
“There are elders in Kitselas that always say, ‘Old villages are really good places to hunt,’ … But basically, these places have not been maintained for, you know, 200 years. … A huge part of our research is actually employing different management strategies, clearing the forest garden areas and getting them back to a place where they can be producing lots of food for people locally.
“BASCOMB: And what did you learn about these forest gardens from the First Nation elders that you spoke with? …
“ARMSTRONG: The elders had pointed me in [the direction of hazelnuts, which I was studying], saying, well, it’s not just hazelnut. [It’s] Pacific crabapple, it’s Saskatoon berries, it’s soapberries. And so, you know, they’re the ones that were leading a lot of this inquiry. And of course, we know from them all the different ethno-botanical uses of plants. … A lot of our research is kind of being led by them and the questions that they have about these places that we can answer.

I heard that piece and thought it was fascinating!
There’s a picture of a kind of wild rice that I’d never seen. So much yet to learn!
Also reminds us of what skilful agronomists those folks were/are.
