9.6     TEMPORARY GROUND PROTECTION
Where access over the TPZ area is required during construction, site preparation is crucial to
minimise damage and disturbance to the ground in which the roots of the trees are growing.

These measures aim to reduce the compaction and disturbance to the soil, spreading the load
of machinery and preventing wheel/track ruts from site machinery. There is a range of
measures and materials that can be used to achieve this. The level of ground protection
required is determined by the load, actions, and frequency of access for works to be
undertaken.

    •   200mm of forest mulch placed over root zones where occasional, light access only is
        to occur.
    •   Geotextile membrane can be laid on the surface with aggregate placed on top to create
        light vehicle access.
    •   Suitably thick rumble boards (e.g. pine sleepers) can be strapped together and laid
        over the aggregate for additional load bearing capacity.
    •   For light rubber track/wheeled vehicles, and/or heavy pedestrian use, ground
        protection mats are considered suitable.
    •   These temporary measures can be wholly removed when access is no longer required.
    •   The mulch can be reused and spread throughout the site.
