Macro ๐Ÿ“ท: City Nature Challenge 2021 (in the South Downs…)

In recent months I’ve become somewhat addicted to iNaturalist. It’s a website or app which collects species records but has AI which can identify a species from a photograph. It can be used by anyone and even has an auxiliary app called Seek which can scan plants, animals, fungi and other animals and identify in real time. It’s the way ecological monitoring is going. Nature conservation is dominated by too small a cohort of people and needs to find ways to open its doors to more people. I will never forget hearing of a lifelong species recorder who wouldn’t provide their sightings to science, and that they would rather be buried with them than share them.

It’s lamby time

Onto more inclusive ways of thinking, over this bank holiday weekend it’s the City Nature Challenge (CNC) where people the world over submit species records to iNaturalist and into the project. As of 10pm on Sunday 2nd May there have been 631,418 sightings submitted. Amazing!

I went to a part of the South Downs that was just about included in the Brighton CNC catchment. I used my zoom lens rather than a dedicated macro because I was doing general ‘work’ with creatures great and small. I used an Olympus 12-45mm lens which can still do macro to a degree (in normal camera terms it’s 24-90mm because I was using a Micro Four Thirds camera, which has a cropped sensor). It worked like a dream.

Xanthoria parietina, a sunburst lichen

I photographed each species once, rather than everything, which would never work – can you imagine? I’d still be there now. I really noticed how, even though I probably recorded about 100 species on the South Downs Way, it was dominated by a small number of species. Ground ivy was very common, as was hogweed, white deadnettle and nettles.

Another Xanthoria sunburst lichen

The most dominant species were nitrogen-loving, just like this golden shield lichen above which is able to deal with fertiliser and other agricultural pollutants. I wonder how different things might have been before the Second World War’s agricultural boom. The Downs is known to have lost a vast area of chalk grassland in the 20th century, one of the rarest and richest habitats in Britain.

Two ravens (centre) and a red kite

I will save you all the generic images of flower-less plants. I did manage to capture record shots of ravens mobbing a red kite, of which there were several. I love ravens, they are such intelligent and characterful birds. They are also not quite common enough to feel as familiar as crows or jackdaws.

A heath snail

One of my favourite encounters was with this heath snail which was curled up (so to speak) in the flower head of a dandelion or hawkbit. I instantly saw this and started talking to myself dangerously loudly about what a nice image it was. I hope you agree!

Hawthorn trees with the Arun Valley in the background

I inspected some old hawthorns that were dotted on the edges of the grasslands. I’ve heard they’re good places in the South Downs to find lichens. Though I found nothing outrageous, there were some beautiful species growing on the branches.

These are possibly the beard lichen Ramalina farinacea. iNaturalist has a weird name of farinose cartilage lichen. Farinose seems to mean mealy or floury. That’s a new one for me.

A small parcel of woodland atop the Downs

On this section of the South Downs Way there is a sudden square of woodland which the path cuts through. I had always thought this was perhaps planted or some recent woodland that had grown up on fallow land. But I found something that makes me think very differently about it.

Town hall clock

This is the first time I’ve seen town hall clock or moschatel. I was amazed to find it. It’s an ancient woodland indicator, which suggests that the woodland is far older than I had realised.

Cowslips flowering en masse

It was nice to witness the typical downland spread of cowslips. Last year we got locked down before this began, and now I’m just getting back here at the point that they’re peaking.

The view towards Amberley

The weather started behaving like something you’d expect in the Yorkshire Dales which cut my species recording short, bar a few desperate snaps in the cold and wet march back to the start.

I managed to capture this footage of a hunting kestrel, hardly macro, but worth sharing.

Thanks for reading.

  1. I always loved that area around Billingshurst, Arundel, Bignor etc.

    Thanks for posting this.

      1. Love the Downs. And we last walked the SDW about three years ago. Now restrictions are easing we’ve just started by getting the bus to Lewes and walking up to the top. Keen to do more!
