The rail network is on the wrong track with the culling of the tree | letters

Article Sandra Laville (mile after Mile of stumps: anger at waypoint cull tree, April 30) once again underlines the decisions about the care of trees and control was made without a full understanding of the role of trees and other vegetation on the landscape. The design of the railway network of trees is justified as necessary to reduce the risk of accidents (falling branches and trees) and delay (as a result, the leaves fall on the tracks). Although these objectives may be valid, it is the policy of “scorched earth” exposes the underlying layers of soil, making it vulnerable to rain erosion, and even the slippage of the earth.

In the days of “railroad construction”, the person responsible for maintaining the vegetation growing in the area was cut back as necessary pruning or felling, stumps and allowed to grow. In this case, the immediate working area, including the visibility of the signals is protected. This left most of the vegetation in the obligations intact of the railway. As a result, the underlying soil was not affected by rain, and the roots kept the soil from water that escapes from aquifers, which were exhibited in the construction of the railway.

Trees produce and shed leaves. During the greater part of the day, these waterfalls are of limited value because of the vortex caused by the passage of each train prevent fallen leaves, many of which tore off on the highway. This is the night that falling leaves can accumulate on the line. Clearly works the night trains, just to break these sheets is impractical. Debris, including leaves, is trapped by low vegetation. As such, the preservation of low-growing, woody vegetation (e.g., blackberries) at the track should alleviate the “problem sheet”. This vegetation is used to represent a fire hazard, especially where running locomotives. Diesel and electric trains is not the same risk.
