Trust Woodland to Supply Timber

What do Acute Oak Decline, The Red Squirrel Survival Trust and the silviculture reduction of oak rotation from 140 years to 100 years have in common? I can think of two or three answers around the work of the late Peter Goodwin.

Peter was from a family of cabinet makers and with Lewis Scott founded the Woodland Trust a charity focused on forestry and users of the different types of wood. The trust is a fount of knowledge about our native trees, tree planting advice and woodland based education.

Book Cover

Acute Oak Decline (AOD)

  • AOD is an aggressive disease which can result in high levels of tree mortality within 5 years of diagnosis.
  • Like chronic Oak decline, AOD affects pendunculate and sessile oak trees that are over 50 years old
  • AOD is caused by a pathogenic bacteria that attacks the trunk of the tree causing a dark, sticky fluid to ooze from cracks or lesions in the bark.
  • Trees may also suffer from canopy dieback, similar to that in chronic oak decline.
  • Chronic Oak Decline is a less vociferous disease caused in part by insect damage caused by the leaf roller moth caterpillars .
  • The Woodland Trust has sponsored research into the problems and potential treatment.

The Red Squirrel Survival Trust

  • The American grey squirrel is a destructive pest that has displaced many colonies of red squirrels.
  • By keeping reds and greys apart, red squirrels can be allowed to thrive protecting the biodiversity of Britain’s native woodlands.
  • Other activities of the trust include establishing new red colonies across the UK wherever feasible and funding research.

 Ancient and veteran trees

  • The British love ancient trees, the stories associated with them, cultural connections and historic uses of timber for dwellings ship building etc.
  • The number of ancient trees in the UK (127,595) is exceptional. Many look special and support rare fungi, plants and animals.
  • Visit the Woodland Trust’s  Ancient Tree Inventory to find ancient trees near you. ‘You’ll be able to record one that is missing or search the database for the largest or oldest trees in any part of the UK.’

Trees Near Buildings

Trees take up large volumes of water during summer. Shrinking and swelling of clay soils can be a concern but trees 30 feet from buildings should not be a major concern. However it is wise to avoid large vigorous trees like Oak, Poplar and Willow.

Root Damage

  • Main roots are usually confined to the top 3 feet of soil
  • Shrubs and climbers are seldom implicated in root damage.
  • Swelling trunks close to buildings may squeeze against structures.
  • Root size and extent is variable dependant on species.They seldom penetrate well maintained drains but vulnerable drains should be repaired.
  • Roots radiate irregularly seeking moisture and nutrient. They may spread two to three times the height of the tree.

Subsidence & Structural Damage

  • Older buildings with shallow foundations are more vulnerable.
  • Soils other than shrinkable clay do not swell and contract as much as other soil and seldom cause damage.
  • The side of a building nearest the tree can settle due to its weight in dry soil causing cracked masonry, distorted doors and windows.
  • Fences, hedges and boundary walls may be damaged by proximity.
  • Paths can be lifted by robust roots.
  • Wind damage to trees may make them structurally unsafe.

General Tree Issues

  • A tree is the responsibility of the landowner who may be liable for any damage it causes.
  • Check with the local planning authority to establish if a tree has a ‘Tree Preservation Order’. They should also know if the garden is in a designated conservation order whose objective is to conserve landscape and public spaces in an area.
  • Trees have atendency to grow larger than you originally intended. They can block out light through your windows, shade gardens and over hang into your neighbors garden.
  • If you need to remove a large tree be aware that the large volume of water it previously transpired will remain in the ground and may lift the water table, swell the soil and cause ‘heave’ or displacement.
  • Gutters and roofs may suffer from leaf litter.
  • Surface roots and suckers can be invasive.

Further Tree Safety Tips

  • Think about the future life and nature of your tree before planting or starting work. It pays to plan ahead.
  • If a large tree needs pruning, lopping or taking down use a tree surgeon who has full insurance.
  • Consider neighbors and  overhangs across roads and public paths.

Part of a Slideshow / Set forming a virtual tour around the lake at Lake Wood, on the outskirts of Uckfield, East Sussex, England, UK. [Map]

The artificially expanded lake and woodland is adjacent to, and to the north of, West Park Local Nature Reserve. The two areas are separated by Rocks Road (the B2012 Uckfield / Piltdown road). Both areas formed part of the Rocks Estate, owned for 200 years – and landscaped in the style of Capability Brown – by the Streatfield family. A tunnel beneath the dividing road (now bricked off) enabled carriage access to the lake from Rock House.

The area has numerous Ardlingly Sandstone outcrops. Where these obstruct the path around the lake, a tunnel – and also steps leading down to an underground boat house cave – were excavated.

Lake Wood is managed and protected by The Woodland Trust

Baobab comments from elsewhere

    • ‘The Baobab is called the Tree of Life with good reason. It is capable of providing shelter, food and water for the animal and human inhabitants of the African savannah regions.
      The cork-like bark is fire resistant and is used for cloth and rope. The leaves are used for condiments and medicines. The fruit, called “monkey bread”, is rich in vitamin C and is eaten. The tree is capable of storing hundreds of litres of water, which is tapped in dry periods.
      Mature trees are frequently hollow, providing living space for numerous animals and humans alike.There are also numerous superstitions amongst native African people regarding the powers of the tree. Anyone who dares to pick a flower, for instance, will be eaten by a lion. On the other hand, of you drank water in which the seeds have been soaked, you’d be safe from a crocodile attack.’ From Baobab solutions for more information

  • The crab apple is the ancestor of the cultivated apple, over 6,000 varieties having been bred over the ages.
  • For sheer flower power it’s hard to beat M. floribunda with red buds opening to pink then white blossom, followed by red and yellow fruit. A good choice where space is limited is Malus ‘Royal Beauty’, a weeping tree with reddish purple flowers, purple-bronze leaves and dark red fruit.
  • Birds will feed on the fruit, particularly robins, starlings, greenfinches and thrushes and the colourful flowers will attract bees in spring. Additionally the native crab apple can be home to over 90 insect species. RSPB
