RFI - Attachment 3 - Arborcultural Impact Assessment Report · 132003.221108.3

Dead:                      Cessation or near cessation of all metabolic processes
Poor:                      Indicating symptoms of extreme stress such as minimal foliage, or
                           extensively damaged leaves from pests and/or diseases. Death probable if
                           tree deteriorates further.
Fair:                      Not nearly of ‘Good’ condition (see below)
Good:                      Usual for that species given normal environmental conditions – full canopy
                           with only minor deadwood, normal leaf size and extension growth, minor
                           pest or disease damage
Excellent:                 Better than usual for that species under normal conditions
HEIGHT                     The distance in metres from the ground to the highest point in the crown,
                           calculated in the vertical plane. This measurement unless otherwise
                           specified is estimated.
INCLUDED BARK              A tight union within a tree that has included bark (bark pressing on bark),
UNION                      often in a ‘v’ formation.
LOPPING / TOPPING          The removal of parts of a tree giving no consideration to the trees natural
                           defence systems.
PRUNING                    Systematic removal of branches from a plant whilst giving consideration to
                           the trees natural defence systems.

RETENTION VALUE            Relates to a combination of factors including condition, location, amenity
                           and ULE
Nil:                       Tree would be expected to die or fail in the near future or is of very high risk
                           or a significant weed
Low:                       Easily replaced or may become problematic if retained given the location
                           and species
Moderate:                  An asset to the area, retention is desirable, of fair to good condition, not
                           easily replaced
High:                      Prominent or valued tree with high amenity and low risk.

                           (Trees on neighbouring properties are assigned a 'High' retention value and
                           should be protected regardless of amenity value)
RISK                       The combination of the likelihood of an event and the severity of the
                           potential consequences.
STRUCTURAL ROOT            The area around the base of a tree required for the tree’s stability in the
ZONE (SRZ)                 ground. The woody root growth and soil cohesion in this area are necessary
                           to hold the tree upright. The SRZ is nominally circular with the trunk at its
                           centre and is expressed by its radius in metres. This zone considers a tree’s
                           structural stability only, this is different from the root zone required for a
                           tree’s vigour and long-term viability, which will usually be a much larger
                           area (see TPZ).
