Opinion | To Save Life on Earth, Bring Back Taxonomy

Naming species has been a victim of a broad shift in our scientific priorities. But we need it more than ever.

The consequences of allowing taxonomy to falter are significant. Every year, botanists around the world discover around 2,000 new plants, a number that has held fairly steady since 1995, suggesting that there are still tens of thousands of plants to introduce to science. Three-fourths of the new species are already threatened with extinction. If we don’t have taxonomists to describe these species, we stand little chance of saving them — or their habitat.

With the threats of climate change, nuclear war and artificial intelligence bearing down, the act of simply itemizing our plants can seem trivial. But when I asked Art Gilman, a botanist, taxonomist and author of “The New Flora of Vermont,” why it matters, he paused in the careful way of a scientist. He gave no answer about curing cancer or revolutionizing food systems. “We lose the opportunity to know our world,” he said, finally.

Ok but can we talk about non-native and invasive species in a nuanced way?

There’s more to this topic than ‘native = good’ and ‘non-native = invasive and therefore bad’. I also see horrible analogies with human immigration, which…no. Just no. 

Let’s sit back and learn about species and how they work inside and outside their native ranges! Presented by: someone who studied ecology.

Broadly speaking, when talking about species in an ecosystem, we can divide them into four categories: native non-invasive, non-native, non-native invasive, and native invasive.

Because ‘native’ and ‘invasive’ are two different things. 

Native and non-native refers to the natural range of a species: where it is found without human intervention. Is it there on its own, or did it arrive in a place because of human activity?

Non-invasive and invasive refers to how it interacts with its ecosystem. A non-invasive species slots in nicely. It has its niche, it is able to survive and thrive, and its presence does not threaten the ecosystem as a whole. An invasive species, on the other hand, survives, thrives, and threatens the balance of an ecosystem. 

Let’s have some examples! (mostly featuring North America, because that’s the region I’m most familiar with)

Native Non-invasive

Native bees! Bee species (may be social or solitary) that pollinate plants.

And stopping here bc I think we get the point.

Non-native

Common Dandelion: Introduced from Europe. Considered an agricultural weed, but does no harm to the North American ecosystem. Used as a food source by many insects and animals. Is prolific, but does not force other species out.

European Honeybee: Introduced from Eurasia. Massively important insect for agricultural pollination. Can compete with native pollinators but does not usually out compete them.

Non-native Invasive

Emerald Ash Borer: Beetle introduced from Asia. In places where it is non-native, it is incredibly destructive to ash trees (in its native range, predators and resistant trees keep it in check). It threatens North America’s entire ash population.

Hydrilla: An Old World aquatic plant introduced to North America. Aggressively displaces native plant species, and can interfere with fish spawning areas and bird feeding areas. 

Native Invasive

White Tailed Deer: Local extinction of the deer’s predators caused a massive population boom. Overgrazing by large deer populations has significantly changed the landscape, preventing forests from maturing and altering the species composition of an area. Regulated hunting keeps deer populations managed.

Sea Urchins: The fur trade nearly wiped out the sea otters that eat them. Without sea otters to keep urchin populations in check, sea urchins overgrazed on kelp forests, leading to the destruction and loss of kelp and habitat. Sea otter conservation has helped control urchin populations, and keeps the kelp forest habitat healthy.

There are a few common threads here:

The first is that human activities wind up causing most ecosystem damage. We introduce species. We disrupt food chains. We try to force human moral values onto ecosystems and species. And when we make a mistake, it’s up to us to mitigate or reverse the damage.

The second is that human moral values really cannot be applied to ecosystems. There are no ‘good’ or ‘bad’ species. Every species has its place. Applying emotional and moral rhetoric to ecology works against our understanding of how our ecosystems work. 

Third: the topic of invasive and non-native species is more complex than most of the dialogue surrounding it. Let’s elevate our discussions.

Fourth: If you ever compare immigrants or minorities to invasive species, I will end you.

There are more nuances to this topic than I presented as well! This is not meant to be a deep dive, but a primer.

Striped bark maples which give good all season interest and I went on a buying spree 20-30 years ago. Bark in general is really undervalued in gardens as a feature.

Acianthus caudatus.

Orchidaceae: Diurideae.

I learned that the fruit of the [mesquite] tree was one of many in our landscape that had evolved to be eaten by the giant mammals who disappeared from this continent not long after humans showed up, one of those factual nuggets that punctuate a truth about the deep history of the Anthropocene in ways reading alone cannot. […] [W]e will soon need to learn not to take for granted things like the wild food that goes uneaten due to the absence of the animals whose extinction our dominion coincided with.

I wonder what kind of cake we will make, if we have to make it from the fruit of the old tree that grew up in the brownfield.

FINALLY the buttonbush pictures. These are just about the coolest flowers in the world. And they grow all over the riverbanks and are swarmed with pollinators right now it’s amazing. My mom and I couldn’t canoe 10 feet without spotting another one and of course we couldn’t not check out every single one.

Yareta (Azorella compacta) in Bolivia (elevation of 14,000 ft.).

This may look like a moss, but it isnt! This is a broad-leafed plant in the carrot family, Apiaceae.

These plants can grow to bve over 3000 years old. This large specimen may be over 1000 years old.
