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.

Ragwort

Erica pyramidalis, the pyramid heath, was a species of Erica (also sometimes known as heath/heather) that was endemic to the city of Cape Town, South Africa. Erica is a genus of roughly 857 species of flowering plants in the family Ericaceae. The Pyramid Heath was restricted to what today is the city of Cape Town in the Western Cape Province, South Africa.The species disappeared due to the destruction of its habitat by the expanding city, and, despite the fact that the species was even cultivated for some time it is now considered extinct.

York groundsel blooms again in Britain’s first-ever de-extinction event

Yellow flower that only grows in York went extinct in 1991 brought back to life by Natural England experts

York groundsel was a cheerful yellow flower that slipped into global extinction in 1991, thanks to overzealous application of weedkiller in the city of its name.

But now the urban plant has been bought back to life in the first ever de-extinction in Britain, and is flowering again in York.

The species of groundsel was only ever found around the city and only evolved into its own species in the past century after non-native Oxford ragwort hybridised with native groundsel.

York groundsel, Senecio eboracensis, was discovered growing in the car park of York railway station in 1979 and was the first new species to have evolved in Britain for 50 years, thriving on railway sidings and derelict land.

But the new plant’s success was short-lived, as urban land was tidied up and chemicals applied to remove flowers dismissed as “weeds”.

It was last seen in the wild in 1991. Fortunately, researchers kept three small plants in pots on a windowsill in the University of York. These short-lived annual plants soon died, but they produced a precarious pinch of seed, which was lodged at Kew’s Millennium Seed Bank.

Andrew Shaw of the Rare British Plants Nursery had a vision to bring the species back to life, but when tests were carried out on some privately held seeds very few germinated successfully.

So Natural England, the government’s conservation watchdog, quickly authorised a de-extinction attempt via its species recovery programme, which has funded the revival of the most threatened native species for 30 years.

“The Millennium Seed Bank said the seed was getting near the end of its lifespan and so we thought we would only have one more chance of resurrecting it,” said Alex Prendergast, a vascular plant senior specialist for Natural England.

Natural England paid for a polytunnel at the Rare British Plants Nursery in Wales, where 100 of the tiny seeds were planted. To the botanists’ surprise, 98 of the seeds germinated successfully. The polytunnel rapidly filled with a thousand York groundsel plants.

In February six grams of seed – potentially thousands of plants – were sown into special plots around York on council and Network Rail land.

This week, the first plants in the wild for 32 years began to flower, bringing colour to the streets and railway sidings of York.

This de-extinction is likely to be a one-off in this country because York groundsel is the only globally extinct British plant that still persists in seed form and so could be revived.

But Prendergast said the de-extinction showed the value of the Millennium Seed Bank – to which plenty of York groundsel seed has now been returned – and there were a number of good reasons for bringing the species back to life.

“It’s a smiley, happy-looking yellow daisy and it’s a species that we’ve got international responsibility for,” he said.

“It only lives in York, and it only ever lived in York. It’s a good tool to talk to people about the importance of urban biodiversity and I hope it will capture people’s imagination.

“It’s also got an important value as a pollinator and nectar plant in the area because it flowers almost every month of the year.”

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.

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.
