The Wood Wide Web and Finding the Mother Tree.
As I wandered through the ancient birch and oak woodland of the Woodland Trust's section of Nettleton Woods, my mind was full of Dr. Suzanne Simard's book Finding the Mother Tree which I found incredibly moving, both on a personal level as well as a scientific one. She is best known for the research she has done on the underground networks of forests characterised by mycorrhizal fungi and roots. She worked out how these fungi and roots facilitate communication and interaction between the trees and plants of an ecosystem. Within the communication between trees and plants is the exchange of carbon, water, nutrients and defence signals between trees. In 1997 the journal Nature referred to this discovery as the Wood Wide Web. Simard has since identified something called a hub tree or 'mother tree'. Mother trees are the largest trees in forests that act as central hubs for the mycorrhizal networks. A mother tree supports seedlings by infecting them with fungi and supplying them with nutrients as they grow. She discovered that Douglas Firs provide carbon to baby firs and that there was more carbon sent to baby firs that came from that specific mother tree. However she also found that mother trees were using the fungal web to support other tree species. Simard was the primary inspiration for the scientist, Patricia Westford, who, like Simard, was ridiculed by fellow scientists and forest managers before eventually being vindicated, in Richard Powers' 2018 Pulitzer Prize winning novel The Overstory, also an excellent and moving book.
As I wandered through Nettleton indulging myself in the therapeutic Japanese practice of shinrin-yoku or forest bathing I couldn't help but wonder at the amazing world, not only around me, but beneath my feet. As I walked I kept my eyes open for the Mother Trees, some ancient and venerable oaks and birches being prime candidates. One purpose of today's visit was to look for fly agaric toadstools which I found in the same place as last year. Although poisonous to us, fly agaric forms mycorrizhal associations with a range of trees, notably birch and and pine, both part of the community of Nettleton Woods.

The Fantastic Mr Fox
As I walked through the cemetery, autumn colours were just beginning to sparkle on the trees. I opened the gate into the woodland burial ground and there he was again basking in the sun like last time. He/she seems to be bold and fearless, obviously habituated to people. He only allowed me to approach so far before retreating to the undergrowth, however.
Continuing my walk around the perimeter I was fascinated to see an apple tree laden with rosy fruit. Presumably it has grown from an apple core discarded by a visitor to the cemetery. There are also some heavily fruiting crab apples in this part of the cemetery too, but a green, rather than a red variety so not sure what sort of jelly they would make.
Further around I was pleased to see the spindle trees now with open fruits displaying the orange seed. Although the insignificant flowers are white earlier in the year in autumn they create a magnificent display. Although the spindles here are most likely planted for ornamental purposes, in the wild they are an indicator of ancient woodland. The wood from spindles is creamy-white, hard and dense. It is straight grained and was once used to make 'spindles' for spinning and holding wool (hence its name), as well as skewers, toothpicks, pegs and knitting needles.
The guelder rose berries are now well-ripened but it needs another week or so before the foliage reaches its full autumn glory.
