Over the winter break I had the pleasure of spending a couple of days in the Cumbrian town of Cockermouth. The drive was hefty and seeing as I most likely wont be returning for the foreseeable future I decided to make the most of my trip by spending a day in the nearby Borrowdale Rainforest National Nature Reserve. It is one of England’s largest remaining temperate rainforests. The unique conditions of its ecosystem are maintained by the oceanic climate of the western coast of the UK, that allows for high levels of rainfall and humidity, and a temperate climate with relatively little changes in temperature year round. These characteristics make it an ideal location for epiphytic flora (Nonparasitic plants that grow on other plants) to attach themselves to every wet and porous surface as well as various types of ferns. Being an old growth forest, it has a well established mycelial network and is rich in bryophytes (mosses and liverworts).
“The Borrowdale Oakwoods are one of England’s largest remaining pieces of temperate rainforest that once spread from the north of Scotland down the west coast of England, Wales and Ireland and are part of a long standing cultural landscape.”
(National Trust, 2023)
Now recognised as ecologically significant the National Trust are aiming to reconnect these fragments of rainforests, in the hope of preserving this special habitat, in turn making them more resilient to the climate crisis. Vast swathes of temperate rainforest could once be found throughout a large portion of the UK. As a result its preservation also protects an important piece of British cultural history. Unfortunately the area of Britain covered by these forests currently stands at a mere 1% due to thousands of years of logging for timber, and clearance for farming and development.
My reasons for visiting concern the diverse array of lichen species that have specialised to live in this particular habitat, some of which have become rare throughout Europe and elsewhere. Being a beginner within such a multifaceted subject matter means that my identification skills will need a lot more field work to sharpen. As a result, my time spent in this forest felt more like a practical introduction to the world of lichen. Starting at Ashness Bridge I walked through the woodland, taking various field recordings along the way, eventually reaching and walking alongside the River Derwent. Despite the wintry nakedness of the forest canopy, the propensity of moss, lichen, ferns, streams and boulders in the understory imbued the landscape with an enchanting atmosphere, made all the more so by a blanket of frost that stretched on past the horizon. It is no surprise that these lush green forests inspired all sorts of British folklore throughout the ages.
My time here provided me with a good opportunity to test out my new field recording rig. The quick release gadget I’d recently purchased made switching between set-ups much easier. As a result I was able to quickly capture interesting sounds when on the go while also perching my mic stand in certain spaces. The latter meant I could stand a distance away while recording so as to not change the sonic characteristics of a place with my presence. Due to it being the height of winter however, there was not too much going on sonically in regards to wildlife. As a result I was drawn to the streams that ran down from the surrounding hills, through the forest, and into the Derwent Water. I quite enjoyed experiencing the sonic architecture of these babbling brooks up close, recording them from multiple different perspectives. I couldn’t help but think of Jana Winderen and Annea Lockwood while doing so. Although I would’ve been more than happy to go on exploring these bodies of water, after an hour or so I had to remind myself of my initial purpose here. Nevertheless, such bodies are a central feature of temperate rainforests, a lot of which are found on steep sided valleys like the one I was on, contributing to their wet and humid ecosystem; This felt reassuring.
At one point in the day I decided to give my hands a rest, and propped a mic stand in my bag so that a pair of mics in an ORTF configuration poked out the top, inspired by a similar example used by the … in the film SOA (Pictured Below). This allowed me to experiment with recording on the go in a different way, although this resulted in a lot of self-induced noise in the recordings. I also had some success recording the actual sounds of the Lichen themselves. Mainly working with Foliose (Leafy) and Fruticose (Bushy) Lichen, I used a Lom Geofon to record any vibrations and other hidden sounds. Having a contact mic handy might have also produced some interesting results but I was unable to acquire one in time. I was also able to record some watery movement in some of the Oak trees by inserting the Geofon into holes and gaps in their trunks. I assume these sounds are sap flowing up and down the tree’s vascular tissue (xylem and phloem vessels) but I can’t be certain. What these recordings assure us of however, is that their is most likely much more sonic activity in this forest that lie outside of our perceptive capabilities. Using such microphones offers a bridge to hearing these invisible worlds (thinking back again to an increased intimacy).
Ahead of this visit I emailed a member of the National Trust asking for permission to forage lichen. I was given the go ahead on the grounds that I only took small amounts of more common species, as well as only foraging from fallen branches or surrounding debris. I managed to attain a small collection of varying types, two of which I have identified as an Oak Moss (Evernia Prunastri) and a Beard Lichen (Usnea). Upon returning home I left them out to dry and secured them in airtight containers.
Footnotes
- Borrowdale comes from the Norse Borger Dahl or ” Valley of the Fort”, the earlier Celts named the water here Derwent or “Abounding in Oaks”. Trees, and oaks in particular, were sacred to this early British culture and so such a valley would have surely been a significant destination. Oaks have remained a symbol of English culture and strength and it is by no accident that it forms the logo of the National Trust. Today, the oak woodland here still draws the local community and visitors from across the UK to come and spend some time in its peaceful and inspiring presence and should be protected as a piece of our collective cultural history.
- These special places are even home to globally rare species, such as the hazel gloves fungus, which grows only on old hazel trees and looks like a bundle of rubbery orange fingers + Tree Lungwort, a large and leafy lichen that needs very clean air to survive.
