Ash © Robert Graham. Latin name Fraxinus excelsior Fraxinus excelsior buds, Fraxinus excelsior fruits © Sten Porse, How to spot Fraxinus excelsior The ash tree is deciduous, so it drops all its leaves and stands bare in Winter. It is still easily identified without leaves by smooth Left to right: grey twigs that hold sooty, black leaf buds. The bark of a young ash tree is smooth and greenish-grey, turning ASH FACTSHEET ASH darker grey and forming deep cracks with age. Ash tree leaves that unfurl in Spring are compound, divided into pairs of leaflets along a long leaf stalk. They usually have 3-6 pairs of light green pointed leaflets with a single leaflet at the Compound leaves end of the leaf. are made up of many smaller leaves called In late Summer they have large clusters of leaflets that are joined green winged fruits known as ‘keys’ that turn to a single stem. brown after the leaves have fallen in Autumn. Our UK native ash tree can grow to be one of the tallest trees in a woodland reaching up to 40m in height. Where it grows Ash trees often grow in groups and can be found in woods, along hedgerows and in streets and parks. It is one of the UK’s most abundant trees, although less common in northern Scotland.

Unlike the ash, they do not have distinctive Sorbus aucuparia black buds in Winter and have bunches of creamy-white flowers in Spring which turn into green and then orange berries in Autumn. The tree crown is the top part of the tree, with branches that grow Why it needs protecting out from the main trunk and support the leaves. Ash trees across Europe are being killed by a serious disease called ash dieback. This disease, caused by a fungus, results in leaf loss and tree crown dieback in infected trees, potentially leading to the death of the tree. Ash is a very important tree in the UK and is the sole source of food for over 27 species of invertebrate. ASH FACTSHEET ASH The spread of ash dieback and the depletion of this important tree could be damaging to many of the UK’s wildlife species. Benefits for wildlife Ash trees make the perfect habitat for many different species of Andrew Curtis. Under the ash tree © wildlife with birds including woodpeckers and owls using the trees for nesting. Ash trees live for a long time and as older trees contain a mix of living and dead, decaying material, they provide an excellent habitat for the lesser stag beetle and other minibeasts that thrive on deadwood. Did you know? Ash is one of the toughest hardwoods and absorbs shocks without splintering so people have used it to make tools for years. Ash timber has been used to make hammers, axes, spades, hockey sticks and oars. Get involved Have you seen any spectacular ash trees lately?

Tree Planting and Management
COMMONWEALTH WAR GRAVES COMMISSION Tree Planting and Management Breadth of Opportunity The spread of the Commission's responsibilities over some 148 countries in temperate, mediterranean, tropical and desert climates provides wonderful opportunities to experiment with nature's wealth of tree species. We are particularly fortunate in being able to grow many interesting and beautiful trees and we will explain how we manage them and what splendid specimens they can make. Why Plant Trees? Trees are planted for a variety of reasons: their amenity value, leaf shape and size, flowers, fruit, habit, form, bark, landscape value, shelter or screening, backcloth planting, shade, noise and pollution reduction, soil stabilisation and to encourage wild life. Often we plant trees solely for their amenity value. That is, the beauty of the tree itself. This can be from the leaves such as those in Robinia pseudoacacia 'Frisia', the flowers in the tropical tree Tabebuia or Albizia, the crimson stems of the sealing wax palm (Cyrtostachys renda), or the fruit as in Magnolia grandiflora. above: Sealing wax palms at Taiping War Cemetery, Malaysia with insert of the fruit of Magnolia grandiflora Selection Generally speaking the form of the left: The tropical tree Tabebuia tree is very often a major contributing factor and this, together with a sound knowledge of below: Flowers of the tropical the situation in which the tree is to tree Albizia julibrissin be grown, guides the decision to the best choice of species. Exposure is a major limitation to the free choice of species in northern Europe especially and trees such as Sorbus, Betula, Tilia, Fraxinus, Crataegus and fastigiate yews play an important role in any landscape design where the elements are seriously against a wider selection.

Aronia Medik. (chokeberry, Rosaceae) is a genus of woody shrubs with two or three North American species. Species boundaries and relationships between species of Aronia are frequently under question. The only European species in the genus, A. mitschurinii A.K.Skvortsov & Maitul., is suggested to be an inter-generic hybrid. In order to clarify the relationships between species of Aronia, we performed several morphometric and molecular analyses and found that the molecular and morphological diversity within data on American Aronia is low, and species boundaries are mostly not clearly expressed. Whereas morphology is able to separate American species from A. mitschurinii, there is no support for such discrimination from the molecular data; our analyses did not reveal evidence of A.

Fraxinus Excelsior
ASH TREE (Part 1) (Fraxinus excelsior ) Crann Fuinnseog Another of our native trees, the Ash supports 41 invertebrate species. We invite reader’s to take note of some branches where ‘keys’(seeds) are set in late Autumn and monitor same for flowers next Spring. Ash’s scientific name translates both the ash tree and javelin ( excelsior ); giving us ‘very lofty’ or ‘sublime’. The tree of life to the Celt. To the Roman and earlier Greek classical world – ‘Venus of the Woods’. Our ancient Irish Ogham alphabet, rather than A,B,C commenced B,L,N pronounced Beith, Luis, Nin (also Nuin) and giving us the Birch, Rowanberry and Ash. The T.C.D 9th century Brehon Law manuscript records ash as ‘Uinnius’ and names it among the seven Chieftain Trees – our most commanding of timber trees. It yielded oars, fodder, furniture (when ruling, kings must be seated on a throne of ash), charcoal, hurley sticks, spear shafts, yellow dye and in our day snooker cues. In our central alkaline rich midlands, ash attains up to 40 metres. Our single most nutrient demanding tree of the forest requires four times more macro-nutrients than our oak. Field guides suggest average ash longevity circa 200 years – author recorded 370 annual rings of an ash blown down during the 1997 Christmas week hurricane in the vicinity of Macroom. Our most iconic ash grew at Uisneach (centre of Ireland) – “And it was surely known to you That here the Ash of Uisneach grew, The lordliest tree of forest kind That flung it’s boughs to wave on wind, Counted by chroniclers of kings Among our Isle’s most precious things.

Fruit Trees, Nut Trees, Plants, Seeds, Books & Sundries
Agroforestry Research Trust Fruit trees, nut trees, plants, seeds, books & sundries www.agroforestry.co.uk Agroforestry: what is it? The simplest definition of agroforestry is that it is the integration of trees and agriculture/horticulture to create a more diverse growing system. In agroforestry the aim is to promote more use of perennial crops, notably tree and shrub crops, because they are more resilient, more sustainable and ecologically sound. Agroforestry systems can vary in complexity from the very simple, eg occasional trees planted in pastures to provide shade, emergency forage and nitrogen (via nitrogen- fixing bacteria), to the more complex systems like forest gardens, which may utilise hundreds of species to create a self-sustaining and interconnected system. The Agroforestry Research Trust The Trust is a registered charity, set up to educate and research into perennial crops and agroforestry. We have 20 acres of trial grounds in Devon including forest gardens and other systems. There are public guided tours through the growing season of our sites (see website at https://www.agroforestry.co.uk/research-site-tours/ for info and dates). We also run courses and seminars in forest gardening, growing nut crops and the forest garden greenhouse (with subtropical forest garden) in Devon. Dates and more info on website at https://www.agroforestry.co.uk/product-category/courses/. The Forest Garden Network This is an informal network of people planning or already cultivating their own forest gardens or agroforestry systems on farms, with the aim to facilitate visits to each other’s sites – one of the best ways to improve our knowledge about temperate agroforestry.

Planting Irish Native Bare Rooted Trees
Planting Irish Native Bare Rooted Trees www.learningaboutforestsireland.org Materials you will need: Native bare rooted the tree in the hole and check the trees, a spade, newspaper/cardboard, bark depth. mulch/leaves/grass clippings 1. Use a spade to take a circular sod of turf out of the ground, slightly wider than the roots of the tree. Turn it over and split it almost in half. 4. Hold the tree upright and gently push back the soil, pressing it down onto the roots. Don't compact the soil as this will stop water and air circulation, but make sure your tree is steady and not falling over. 2. Loosen the soil in the hole to a depth of about 15cm. Add some compost and dig it in to the soil. 5. Put the turf back over the hole with the split either side of the young tree, with the grass side down. Trample down lightly with your feet. 3. Look for the “collar”. This is the mark on the tree from where it originally started to grow above ground. This should be level with the top of the soil. If a tree is planted too deep, the stem may rot; too shallow and the roots above ground will dry out and die.

(2019): The reaction of different Sorbus L. species to low temperatures during thaw in the Orel region. J. For. Sci., 65: 218–225. Abstract: Five Sorbus L. species of different ecological and geographical origin growing in the VNIISPK arboretum were studied. The Institute is located 368 km southwest of Moscow, on the Central Russian upland in the European part of Russia. The studies were carried out in 2014–2016. The reaction of different Sorbus L. species to a three-day thaw +2°C with a subsequent decrease in temperature to –25°C in February and –30°C in March was studied in or- der to identify adapted species to the climatic conditions of the Orel region for use in ornamental horticulture. As a result of the experiment, we recommend Sorbus aria (L.) Crantz, Sorbus aucuparia L. and Sorbus alnifolia (Siebold. et Zucc.) K.
