Swiss Alps: where sycamore trees feel at home

Continuing my series of posts about visiting the Jungfrau region of the Swiss Alps in May 2024, this one focuses on the sycamore trees which are so abundant there. They were seen on a short but constantly ascending walk at the foot of the Wetterhorn.

If you want to do this 3-mile walk for yourself, it begins in Grindelwald and ends at the owl sanctuary/mountain café with a return bus available at the end. This is the route we took (ignore the starting point, just begin anywhere in Grindelwald):

I’ve posted a couple of times about the sycamore tree (Acer pseudoplatanus) as I think it straddles that special boundary between human culture and wildness that is probably my creative sweet-spot. In Britain sycamore is at once reviled by nature conservation puritans, accepted by rewilding pragmatists, and held as a symbol for the British love of trees in the form of the illegally felled and now martyred Sycamore Gap tree.

In the Bernese Oberland I saw sycamores playing a fundamental role in cultural landscapes at the foot of the Wetterhorn, one of the Jungfrau’s towering peaks.

What do I mean by cultural landscapes? My understanding and use here indicates a landscape that remains wild or ‘natural’ but with a heavy human influence still. English national parks are cultural landscapes, whereas those managed by wolves and grazing animals without human management plans in North America, are ‘wildernesses’. That in itself is questionable from a Native American perspective, but another blog.

There isn’t a lot of information about sycamore wood pasture as a cultural landscape but for this dissertation about sycamore wood pasture in the Northern Alps.

The Wetterhorn seen above meadows of yellow rattle, and kidney vetch, both growing in profusion.

I posted more generally about the meadows of Grindelwald (a mile west of this location) here:

A reminder that you shouldn’t pick flowers, trample on them, or knowingly disturb wildlife or livestock in these extremely sensitive places. In terms of you being trampled, cattle were behind electric fencing where present.

The cattle are an iconic element of these landscapes in the Alps, and provide an important role in grazing the grasslands.

The signage is impressive in Switzerland, some provide hours and minutes route descriptions of destinations. Not something I’d seen before, but now there’s no going back, or at least if there is, you will know how long it takes!

The walk crosses the Horbach river at least once.

A large, moss and lichen-covered ash tree (Fraxinus) showing no signs of ash dieback disease, thankfully.

It was nice to see some roughness and history in what is an otherwise ‘spick and span’ setting. I presume the huts are built on stone to prevent rising damp decaying the timber frame.

Spiked rampion was a new plant for us. Apparently it’s endangered in the UK. It was growing in woodlands and meadows around the Grindelwald area.

His a mighty view of the Horbach looking towards the Eiger.

Red-banded polypore is common in continental Europe but not as easy to find in the UK, so I always enjoy seeing it.

I love woodland ponds, especially ones as wild and dynamic as this one. This is probably an ancient pond.

After this point you reach a hotel which I didn’t take any photos of. It’s a good place to have a hearty meal. Just don’t expect to charge any devices, we heard an English couple seemingly fall out with the staff over that. Oops.

After stopping at the hotel you pass this incredible cut in the mountain side. The rock looks twisted and dramatically compressed. There’s a small quarry in operation, glimpsed in the right hand corner.

These walks always involve huts belonging to local people. What a life that once would have been.

After this hut we turned into the sycamore wood pasture.

I know very little about mountain hydrology and the role that meltwater plays in feeding ecosystems lower down. But looking at the lushness of this meadows makes me wonder about how the ice melt provides such a fertile location for grassland, and sycamores. Sycamores do well in damp conditions, but not too wet.

Other lifeforms that enjoy wet conditions are of course mosses. They’re thick on this trunk. I didn’t spend any time attempting to identify any.

Fairy foxglove (Erinus alpinus) is another new plant we encountered. It was growing on the footpath.

A view into what I think is the Upper Grindelwald Glacier (Oberer Grindelwaldgletscher).

Walking in such an awesome location can feel rather overwhelming.

View north-east with a group of moss-darkened sycamores before growths of spruce. I think the peaks beyond the snowy tops can be reached by walking into the Grindelwald First gondola, accessible via the town centre.

A view south-west towards the Eiger ridge.

An old pollard sycamore coming into leaf for another year. The trunk is thick with moss and no doubt with lichen and algae too.

The Eiger Trail passes up here over the snow but it was closed due to rockfall.

Early-purple orchid was not a common sighting during our time in the Alps, so seeing one against the vista of Grindelwald was nice.

Looking west towards Männlichen (see post here).

I was intrigued by these stone walls, reminding me of forgotten settlements seen in Ireland, Scotland, Dartmoor or Yorkshire. It’s a contrast with the tidy timbers of Grindelwald.

The walk ends at this lovely cafe on the road, across from the bird sanctuary.

Some old shoes on display. Made with sycamore wood?

Just a few of the treats on offer.

There aren’t many cafes that can beat this view.

The Alpine Bird sanctuary (Alpenvogel Park), home to capercaillie, eagle owl, snowy owl, long-eared and tawny owls.

Britain’s complex relationship with the sycamore tree

One tree story has captivated the UK media in recent months – the illegal felling of the 200-year-old sycamore that grew at Sycamore Gap, one of the most iconic sections in Hadrian’s Wall. For those who don’t know, Hadrian’s Wall is a Roman wall that is also a National Trail in Northumberland, northern England. It was Roman Britain’s northern frontier, the last holdout against the Scots further north.

The appalling felling of this wonderful tree, and subsequent degradation of Britain’s cultural heritage, has unleashed torrents of anger from many different quarters. The culprits, whoever they are, probably now realise that life will be far from simple for them going forward. The regret, you would hope, is immense.

There is a need to understand why anyone would do this, and for it to be understood in the wider context of nature depletion taking place in England, often under Government sponsorship. We should consider infrastructure projects like HS2, which have felled far larger and older trees, and degraded our landscape heritage in ways that have not been seen in a long time. And it’s not a project that is going particularly well.

I don’t want to go on about tree felling misery too much. Instead I thought this would be a useful opportunity to look at the place of sycamore in Britain. It’s not exactly everyone’s favourite tree, but I do love it. If you have any perspectives on sycamore, please feel free to contribute in the comments.

The helicopter tree

As a child my relationship to trees was about seeds rather than leaves. Acorns, conkers, and ‘helicopters’ were the ones I knew. ‘Helicopters’ was the game we would play in the playground throwing the winged seeds of sycamores into the air to see whose landed first. The seeds spun as they fell from the sky, a very happy memory of childhood nature connection.

It is strange how as children these seeds were used as tools of competition, with conker matches taking place via attached strings (a hole had to be drilled through the middle of the conker) and the seeds smashed against each other until only one was left in one piece. Conkers in this instance are the nuts of horse chestnuts.

Winged-seeds are not uncommon in nature, with birch seeds being one very effective winged-seed that can travel for miles and sprout in many different landscapes.

An unloved ‘non-native’?

In woodland management circles sycamore is often viewed as a non-native ‘weed’. People hate it! One problem is that its place in Britain is not fully understood, and there are some reversions to arguably xenophobic views of ‘non-native’ species. Oliver Rackham said that sycamore is either 400 years a British tree or from the Roman period (43-400AD). Though it probably had human help in ‘arriving’ in Britain, it has happily naturalised in many places. It’s likely to have been in Britain for longer than 400 years (see below).

Its lack of popularity among land managers, and particularly volunteer community groups (for some weird reason), is that it’s not believed to support a lot of insects or have expansive fungal relationships. But some of these ideas are contested, and I have seen sycamores in the Scottish Highlands that are dripping in lichen, moss and algae.

Sycamores hold a high density of aphids in the spring which makes them an important foraging resources for birds like blue tit, house sparrow and other small passerines during the nesting season. We have lost massive amounts of insect biomass in England since the 1980s, so sycamore has a big role to play in restoring that.

The Birnam Sycamore

In 2012 my late uncle Joe took me to see the Burnham Sycamore, an ancient and gigantic tree in Dunkeld in Perthshire. This tree is said to be 300-years-old, pushing very close the idea that it has only been in Britain for 400 years. I haven’t seen a sycamore of this size since, but it goes to show that it could become one of the giants of the British Isles, given time.

Another special sycamore that has now been felled – seen here in Widecombe in the Moor, Dartmoor June 2019

A potential replacement for ash?

The wet and cooler climates of Britain and Ireland provide a happy home for sycamore. In Dartmoor National Park in Devon, sycamore grows in places where ash no longer can due to its severe dieback. Again it can be seen festooned with mosses and lichens, providing habitat for lots of different organisms. It seems to enjoy the ‘Celtic landscapes’ of Britain and Ireland and their high levels of rainfall, just like the lichens and mosses it hosts.

New self-seeded woodlands are rather unloved by most land managers in Britain, but with so many tree diseases affecting native trees, sycamore’s ability to create new woodland from scratch is significant. Ash is no longer able to create new woodland, whereas sycamore can. As a pioneer species it can create the condition for the ancient oak and beech woods of the future that are loved by so many.

Squirrel damage

In London, sycamore is struggling to reach maturity in some woodlands. This is because of the actions of grey squirrels, another non-native but classified invasive species that, unsurprisingly, divides opinion. Squirrels strip the bark of sycamore in summer, probably to gather material for their drays. Perhaps they are also aware of the antiseptic nature of the tree, a bit like how some birds of prey add oak leaves to their nests as a natural insecticide. The impact of squirrels results in a mess of dead brown leaves and fragmented twigs. It veteranises a tree but usually at an age too young to make them of long-term ecological value.

Spoon-maker’s dream

For anyone who’s dabbled in whittling, sycamore is one of the absolute best options available. It is naturally antiseptic and has a lovely soft and smooth wood for carving when fresh. There are untapped industries in this kind of woodland produce that could have reduce the demand for plastic utensils and other wooden products from questionable sources.

So, as many people mourn the illegal felling (or maybe coppicing?!) of the sycamore gap tree, it gives us the chance to see where this wonderful tree species sits in our lives. It appears that the fondness is far greater than people realised.
