Garden of Extinction

Standard

Of all the areas of the stunning Kirstenbosch National Botanical Gardens in Cape Town, South Africa – and all the areas are stunning – one in particular stood out. It was probably the smallest section, the least visually impressive, and one where few people lingered.

The Garden of Extinction area is just a tiny corner of the Gardens, which spread over 5 sq km (2 sq mi). Against a backdrop of the Atlantic Ocean and Table Mountain, the gardens are lush, and feature all manner of wondrous plant life from various corners of the world. It’s a place to be edified, dazzled and revived.

But the Garden of Extinction is there for education. There are a few plant species, all of them somewhere on the spectrum from endangered to extinct in the wild.

Most of the species are modest, the kind of plant you would walk through on a windy hillside and only notice if they were in bloom.There are informative panels on how extinction occurs among plant species, and some suggestions for what can be done.

The plants aren’t fenced in as the last and final specimens of their kind, they are there to be experienced like all the other (currently non-endangered) species throughout the park.

That’s a part of the message – it’s not just the milestone species that go extinct.

These aren’t the plant equivalents of the quirky dodo or once-iconic passenger pigeon. These are the everyday plants around us, some of them limited in range but once abundant within their habitats, which are in the brink of disappearing forever.

And in that sense, this is the most powerful message of all: Any species, now matter how unusual or common, is vulnerable if the pressure on habitat becomes too great, if it is over-gathered or hunted, if it can’t adapt to altered conditions in terms of temperature or water availability.

Humankind, by and large, has come of age in an extended time of climate stability. A Goldilocks era that was neither too cold, nor too hot, for the veritable Garden of Eden we needed to grow and thrive.

In this Anthropocene age of the Sixth Extinction, it’s optimistic to think that the Garden of Extinction will remain the smallest corner of the larger garden. But we can still do everything in our power to limit its expansion.

Left To Its Own Design

Standard

Five weeks is an eternity in summer gardening, and five weeks is how long I neglected the garden because of an injury. At some point, I stopped going out there because I couldn’t stop myself from trying to weed and clip, even when every movement was painful. Easier just to watch it from a distance and figure that if there’s one thing a garden doesn’t absolutely need to keep growing, it’s a gardener. I am there to impose my own order, but when it comes to growing, the garden does just fine on its own.

I could probably have hired someone, but that would have felt like an imposition – not on the person hired, but on the garden. On me. It’s my little patch to tend, and my little patch to let run amok.

So when I took a stroll around last week, splints finally off both arms, I was pleased to see that the garden does fine on its own. It might not be going in exactly the direction I would have chosen, but it picks its own path.

There were still a few gems here and there, just blossoming away, bees buzzing and birds singing, the weeds having a wild climb in forbidden places.

There won’t be the harvest I would have wished; the lettuce is shot and and the tomatoes a mess, but it’s still a fine little patch.

Nature finds a way, in gardens and elsewhere.

Lessons in Listening

Standard

For the first time in its 59-year history, the Australian Science Teachers Association’s (STAWA) Secondary School of the Year award, an annual prize handed out in Western Australia, went to a school outside of Perth. That kind of anomaly deserves a second look.

The school that won the award for science research is the Christian Aboriginal Parent-directed (CAPS) school in Coolgardie, an independent school established by Aboriginal parents who felt the quality of education in their region was lacking.  This was also the first time the STAWA award went to a school with a mainly Aboriginal student population.

The students at CAPS were under the tutelage of a young science teacher from the United States, Allan Alipio, who wanted to inspire students with the passion he himself felt for science. He allows the students to come up with some of their own ideas, and this is where I think the story starts to get really interesting.

The projects that won the award were mostly based on the application of native plants and indigenous knowledge to energy and medical experiments. One group of teens investigated the antimicrobial potential of traditional medicine plants maroon and crimson turkey bushes as well as sweet potato leaves for potential use as an anti-diarrhoea medication, while another group used local plants like wheel cactus and gum leaves to make ethanol.

This award speaks to the profound impact that good teaching can have – not just on passing along the facts and passing tests, but on inspiration and passion. I think it’s important to stress that, rather than imposing a standardized curriculum, Mr. Alipio listened to his students.

There’s a lot that could be discussed here about the all-too-common lack of education funding for indigenous populations. This gets at a larger issue of the side-lining (or worse) of indigenous populations around the world, and the extent to which their deep local knowledge has been suppressed, disdained, ignored, or (as with many medicinal applications) commercially exploited. And as we slog through this new era of climate change, that knowledge is more relevant than ever – as is the necessity to start listening.

People who identify as indigenous number an estimated 370 people worldwide, made up of around 5000 groups across 70 countries. They make up approximately 5% of the global population – but traditional lands and territories contain an estimated 80% of Earth’s biodiversity.

Gleb Raygorodetsky put it well in this excellent article: “With collective knowledge of the land, sky and sea, these peoples are excellent observers and interpreters of change in the environment. The ensuing community-based and collectively-held knowledge offers valuable insights, complementing scientific data with chronological and landscape-specific precision and detail that is critical for verifying climate models and evaluating climate change scenarios developed by scientists at much broader spatial and temporal scale. Moreover, indigenous knowledge provides a crucial foundation for community-based adaptation and mitigation actions…

The difference in world views can be as fundamental as the botanical illustrations of plants above done through Western eyes, the illustration of bush plants below done by Aboriginal artist Gloria Petyarre.

I will get into huge topic around the overlap of human rights issues, indigenous peoples and environment another time, but for the moment, I would say this: As long as that deep knowledge stays on a parallel but separate track from Western-based science, policy, legislation and education, we are missing out on critical opportunities to learn and adapt to the changes we have created over a relatively short period of time. At the same time, learning to listen and to cooperate puts people back in the loop when it comes to determining the fate of the land on which they live – and might just help us weather the approaching storm.

Hopefully, students like the award-winning teens at CAPS will be able to leverage knowledge from both worlds to help chart a path ahead.
