At Scott Davies Tree Surgery we can undertake tree care and management services with our fully insured and professionally trained, experienced and well-presented arborists to ensure the job is undertaken in the safest and effect way possible.

Tree Felling and Removal

Tree felling is the operation of cutting down a tree in the saftest and most effective method where space is not limited, when space is limited, our professional arborists will sectional dismantle the tree with rope, pully and lowering equipment suitable for the size of tree at that time.

  • The main reason for tree felling and removal is premodernity for safety purposes such as dead, diseased or dying trees as they can pose a risk to public and property.
  • In some cases, trees are cut down for aesthetic reasons or due to lack of light.
  • Aside form safety, trees might be unsuitable for the location they are I, whether this due to subsidence issues or insurance purposes and their recommendations on felling to recue the risk if subsidence.

Mechanical Tree Dismantling with Grapple Saw

When using grapple saw for mechanical tree dismantling, branches, stems can be held and lowered in a smooth and controlled manner avoiding the fracture and uncontrolled falling of the material.

  • Grapple saw can safety dismantled trees to the ground in a controlled manner with no danger or impact to the surrounding.
  • Mechanical tree dismantling is the suggested method for when trees are affected with diseases such as Ash Dieback, Ash die back threatens United Kingdom tree population, The wood of Ash trees that is infected can become more brittle and susceptible to breaking, especially under loading, and the typical sectional dismantle by rope and harness by an arborist can become dangerous for the climber and operatives.

Tree Pollarding

The pollarding process should begin when trees are very young, before pollarding begins the main trunk and branch architecture should be formed, typically upright or horizontal branches with wide angles of attachment spaced along a dominant trunk are chosen for the main scaffold limbs, then many forms can be created.
After this, the young stem headed at the exact position to which that the tree will be cut at each subsequent pruning, this might reflect site usage and allow pre-existing foliage to be retained, in order to maintain physiological function and thus reduce the probability of die back and death.

Choosing where these pruning points will be important as they may need further work to reposition in the future, if a pollard head is shaded that part will decline, so the location of cuts are important so they receive adequate sunlight from above.

If the pollard cycle has been allowed to lapse over many years the crown should be instead reduced to the minimum necessary to fulfil current objectives like relief of mechanical stress that could cause the stem to split apart.

  • Pollarding tree can provide some relief from the sun without shading out turf.
  • Pollarding can allow people access to views that would be blocked by a large crown.
  • Pollarding can maintain a large maturing tree in a small size if the tree has been improperly located in a restricted soil space such as a planter, narrow soil strip or near street parking spaces.
  • Pollarding can control the size of trees improperly planted close to structures like, buildings, streetlights and electric wires.

Crown Reduction

Crown reduction pruning technique is carried out to reduce a proportion of a trees overall original shape/size and to avoid altering the balance of the tree as a whole, a reduction cut is made which removes a stem back to a lateral branch that is one third the diameter of the cut stem, sprouts commonly follow a reduction cut, if a large portion of foliage was removed with the cut.

Reductions should be specified by actual measurements, where possible, and reflect the finished result, but may also refer to lengths of parts to be removed to aid clarity, e.g. ‘crown reduce in height by 2.0m and lateral spread by 1.0m, all round, to finished crown dimensions of 18m in height by 11m in spread (all measurements approximate.)’. Not all species are suitable for this treatment and crown reduction should not be confused with ‘topping’, an indiscriminate and harmful treatment.

  • Crown reduction alleviates biomechanical stress by reducing both the leverage and sail area of the tree.
  • Allowing retention of a tree in a confined space
  • Also use to create a desired appearance or to make the tree more suited to its surrounding.
  • Produces a compact crown.

Crown Thinning

Crown thinning is the selective removal of live branches to reduce the crown density, material should be removed systematically from throughout the tree rather than from the inner crown only, structurally weak, and hazardous branches should be removed, and an even density of foliage should be retained throughout a well-spaced and balanced branch structure which could if required provide an adequate framework for possible future crown reduction.  

The percentage of leaf bearing twig structure to be removed in crown thinning should be kept to the minimum required to achieve objective and, in any case, not exceed 30%.

  • Produces voids in crowns.
  • Reduces damage in wind.
  • Removal cuts cause little decay.
  • Retains laterals that can be used for crown restoration.

Crown Lifting

Crown lifting is the removal of the lowest branches and/or preparing of lower branches for future removal. Good practice dictates crown lifting should not normally include the removal of large branches growing directly from the trunk as this can cause large wounds which can become extensively decayed leading to further long-term problems or more short-term biomechanical instability.

Crown lifting on older, mature trees should be avoided or restricted to secondary branches or shortening of primary branches rather than the whole removal wherever possible.

Crown lifting is an effective method of increasing light transmission to areas closer to the tree or to enable access under the crown but should be restricted to less than 15% of the live crown height and leave the crown at least two thirds of the total height of the tree. 

Crown lifting should be specified with reference to a fixed point, e.g., ‘crown lift to give 5.5m clearance above ground level.

Stump Grinding

Stump grinding is a process that involves using a machine to remove tree stumps by grinding them into small wood chips and soil.

Stump grinding is a versatile practice with multiple purposes. It enhances aesthetics, improves safety, frees up space for new plants or structures, prevents diseases and pests, aids replanting, and is environmentally friendly. It also speeds up natural decomposition and adds value to properties.

Tree Planting

Tree planting is the process of intentionally placing tree seedlings into the ground to establish new trees or restore existing forests.

Tree planting serves various important purposes. It helps the environment by absorbing carbon dioxide, enhancing air quality, and providing homes for wildlife. Trees also help to prevent soil erosion and stabilise the land. They support diverse ecosystems, make our surroundings more beautiful, and fight against climate change by trapping carbon. Additionally, trees offer shade, reducing heat in cities. Moreover, tree planting can educate us about the environment and provide us with sustainable resources, like fruits, nuts, and wood.
