An autumn narrative

A forecast of rain clearing with some brief intermittent sunshine and low winds before a more extensive weather front arrived presented the opportunity for a quick outing to simply capture autumnal colour in the woodland of the Forest of Dean. Wetted trunks of beech trees and leaves with contre jour lighting would be just the ticket. So a 10 min car journey, 10 minute walk from the car, set up, wait a few minutes for a break in the cloud and hey presto.

Mother trees and forests

If you have a spare 20 mins it is worth watching Professor Suzanne Simard providing insight into the layers of complexity in forests.

"This fascinating talk presents the scientific research that shows the interconnectedness of life in the forest ecosystem. It takes us beneath the forest floor where we learn how trees are communicating and exchanging resources. Going beyond the simple view of a forest as a resource to be exploited, it presents the forest as a complex network of life. Her examination of the relationships that make up the complexity of nature present compelling support for the idea that “We are all one” Suzanne Simard studies the surprising and delicate complexity in nature. Her main focus is on the below-ground fungal networks that connect trees and facilitate underground inter-tree communication and interaction. Her team's analysis revealed that the fungi networks move water, carbon and nutrients such as nitrogen between and among trees as well as across species. The research has demonstrated that these complex, symbiotic networks in our forests -- at the hub of which stand what she calls the "mother trees" -- mimic our own neural and social networks. This groundbreaking work on symbiotic plant communication has far-reaching implications in both the forestry and agricultural industries, in particular concerning sustainable stewardship of forests and the plant’s resistance to pathogens. She works primarily in forests, but also grasslands, wetlands, tundra and alpine ecosystems."

"The best laid plans of mice and men often go awry"

Overnight accommodation was booked to enable two days of photography in the environs of the upper Tywi catchment in the Cambrian Mountains. On the journey there plenty of stunning autumnal colour was passed until entering the Twyi valley, where irrespective of the woodland facing aspect or elevation the majority of oak trees were bare of leaves. Hopes of images capturing valleys mantled with autumnal oak canopies juxtaposed against open moorland were shelved for another year. C'est la vie.

The first day was leaden skies. negligible wind and 'damp' so photography ambitions were instead lowered to riparian woodland and the morphology of oak trees contorted by past events and the necessity for leaves to access sunlight. Considering the morphology and growing habitat some of the trees must be of some age.

High annual rainfall, high humidity, relatively low levels of atmospheric pollution and ancient woodland creates an ideal habitat for epiphytic bryophyte and lichens, so the opportunity was taken to photograph some of the more accessible communities.

Barnacle lichen (Thelotrema lepadinum) and Tamarisk Scalewort (Frullania tamarisci)

Crottle (Parmelia saxatilis)

The sunset vigil was spent above the tree line and hopes of a sunset were briefly raised by breaking cloud on the western horizon and then dashed as the breaks closed. Nevertheless the time spent waiting allowed an appreciation of the surrounding plateau surfaces dissected by valleys and exposed bedrock indicated folding on the northern flank of the Tywi Lineament.

The following day saw the wind increase and the weather forecast predicted cloud would briefly break up before closing, a circuitous walk through the woods and up onto the plateau was opted for. The plateau surfaces posed their usual photography challenge: a distinct lack of inspiration, so photography efforts were concentrated down on the plateau slope edge where woodland was naturally regenerating.

The cloud did eventually break up allowing fleeting patches of sunlight to play over the landscape, frustratingly though never the foreground and middle ground simultaneously during a tactical 'rest stop'. Back down in the valley and a viewpoint was chanced upon that I thought held some potential and then discovered the sun didn't quite clear the ridge, sigh.

With incoming cloud negating sunset, there ended the photography and yet another location to put on the list of places to return to one day.

Reflected and diffuse autumn light

Heavily shaded woodland environments benefit hugely from the illumination of an autumnal canopy that imparts 'warm' light and if a mist is rising then the light is diffused. The combination creates some very special lighting and is generally utilised for photographs of sun beams penetrating through breaks in the tree canopy.

A recent trip to a Scowles woodland was rewarded with the conditions and atmosphere for reflected and diffused lighting, that made venturing forth down into the darker realms a realistic photographic ambition. The lower perspective offers views of outsize tree roots flowing down over bedrock outcrops to form buttresses and the underside of gnarled veteran beech coppice stools with rot hollows that provide insight to their great age. The dense shade and higher humidity also creates the habitat for luxuriant mosses and bryophytes and for my aesthetic tastes the emerald greens contrasts well with the freshly fallen autumnal beech leaves. Whilst sun beams breaking through a canopy provide visual drama, it is well worth bearing in mind that the very same atmospheric conditions can be utilised to photograph more challenging subject matter.
