Revisiting the 2010/2011 survey of veteran trees of Markstakes Common.

Visible to anyone in the world
Edited by Jonathan Vernon, Monday, 23 Sept 2024, 07:02

Markstakes Common is an ancient wood in East Sussex. Over the last 30 months, I have made over 200 trips to learn about veteran trees, discover hundreds of fungi, and get to know this exceptional site of diverse, exceptional habitats. I hope to be around to repeat a survey of the same trees each decade to monitor their health and the health of an ancient wood that warrants designation as a site of particular scientific interest.

Thirty-four veteran trees were identified in the November/December 2010 to January/February 2011 tree survey and verified by the Woodland Trust. Jonathan’s research has resulted in a further twenty-seven trees being verified as veteran trees - with an additional twenty-six being verified as ‘notable’. These are on the Woodland Trust Ancient Tree Inventory. No trees are thought to be ‘ancient’. The definitions notable, veteran and ancient relate to a combination of factors dependent on the maturity phase of a particular species of tree. Yew and oak, for example, reach their final phase of life centuries after Beech and hornbeam, while ash, and certainly birch and hawthorn, can pass through to late maturity in a hundred to 150 years.

It is the ‘ancient characteristics’ of hollowing trunks and branches, cavities, dead wood in the canopy and on the ground, lichen, moss, ivy, fungi, epiphytes and evidence of invertebrate activity which define the tree as ‘veteran’.

The notable tree is often a mature, healthy tree that could be older than the veteran but shows none or very few of these characteristics. Because of how and where they grow in an ancient wood, the trees compete for light by outgrowing each other into the canopy. Beech is far more shade tolerant and, therefore, ultimately dominant in the canopy than the different trees, with oak increasingly shade intolerant. Disease and damaged branches and trunks expose the tree to fungi that may cause parasitic damage. 


The currently surveyed and identified collection of forever changing Markstakes Common trees now recognised as ‘veterans’ comprise seven Ash, twenty-two Beech, two Downy Birch, two Field Maple, two Holly, seventeen Hornbeam, four Oak, two Wild Apple and two Wild Cherry. Of which, nineteen are maiden, seven are old pollard, eleven are old coppice, twelve are multi-stemmed, two are dead, and seven are ‘fragmented’ (a stem or two are broken or fallen). Nine have a companion tree or trees, with these ‘companions’ being (some dead, some alive) three each of oak, hornbeam or holly. 

All the veteran trees have lichen and moss, some with ivy, one or two with epiphytes, and one or two cuckoo trees, many with fungi.

Thirty-three have fungi associated with them, with Bracket fungus (Ganoderma applanatum) on five trees (with two of these trees either long since dead and another two fragmented), two with Hoof Fungus (Fomes fomentarius), several with King Alfred’s Cakes (Daldinia concentrica), two with Cinder Fungus (Kretzschmaria deusta), two with oyster mushroom (three if you include a notable tree), others with porcelain or slimy beech fungus (Oudemansiella mucida), two with Split Gill Schizophyllum commune), one with Bitter Oyster  (Panelius stripticus) two with Oyster mushroom (Pleurotus ostreatus), one with veiled oyster (Pleurotus dryinus) and seventeen trees with the fungus species ‘not yet identified’, usually because whilst there is evidence of a fungus present, the fruiting body hasn’t been seen. 

Thirty-four were identified in the survey from November/December 2010 to January/February 2011. Jonathan has added fifty-three trees, of which twenty-seven have been verified as veteran trees, and the remainder ‘notable’. They were added to the Woodland Trust Ancient Tree Inventory between March and September 2024. 

Nine veteran trees appear on boundary banks, the most promising places for further discoveries. Two of these trees are Trees of National Special Interest: the magnificent chaliced pollarded veteran hornbeam towards the western boundary with Furzeley Farm Paddock and the long fallen but still living hornbeam on the southern boundary with Starvecrow Wood. This potential for further discoveries should keep us all intrigued and hopeful about the future of our tree survey.

The widest girths go to a Beech (tree 10) with a girth of 6.13m in 2010, a Beech (tree 2) girth of 4.86 in 2010 and now 5.09m in 2024, as well as recently added Ash coppices (5.81, and 5.33) (trees 23b & 33b) 

The new additions by species are Downy Birch, Holly, Wild Apple, Purging Buckthorn and Field Maple. 

There are more veterans: Ash, Field Maple, Beech, Hornbeam, Holly, and Downy Birch to add. The twenty-six notable trees of Markstakes Common on the Ancient Tree Inventory include Goat Willow, Crack Willow, Beech, Ash, Oak, and Hornbeam. Many other ‘notable’ trees will be added if a complete picture of the tree stock is required. Their presence is a valuable indication that this wood will continue to produce ‘veteran’ stock in the centuries to come.

Fungi of Markstakes Common

Visible to anyone in the world

Five weeks ago I was invited to give a talk on the fungi of Markstakes Common; not that I'm a mycologist, simply because it is known that I've taken a few nice pictures with my fancy iPhone 11 over the last 9 months. I then sit down to prepare my talk. I'm thinking I'll get to 16 or so mushrooms - the number I estimate I will identify once I start going through the photographs (I have over 2,000 shot on the Common, initially of the 'notable' trees in various stages across the seasons, then what I call 'PosNots' 'Possible Notable' trees which I wish to add to the national register. And then photos (and video) under different weather conditions: drenching rain, frost and snow, as well as high and increasingly low sunshine morning, midday and early evening over the year. Then I get down to pulling out the fungi photos.

I had got to over 60 slides about two weeks ago, and have now pushed it to 87. Even if you take a few off the times I have used two slides that still is far more than I expected, and a morning workshop not a short talk at an AGM. I'll have to pick my favourites.

That is how scientific it will be: the ones that look the best, so the Oyster Mushrooms I spotted a few weeks ago, the Scarlet Elfcup I was amazed to spot the other day (I thought it was a crushed Coke can someone had pushed under some logs), as well as the extraordinary Candlesnuff, Coral and Porcelain mushrooms, and the tiny bonnets, Puffballs, Common Earthball as well as Polypores, Brackets and Conks. 

A close up photograph of a porcelain mushroom which is white, delicate, like a miniature Starship Enterprise on a stick!

That would do it. I'll leave slimes and moulds for another day and won't even start on lichens.
