7 Glossary
Age Category :             The age of the tree is represented as Juvenile, Semi-mature, Mature or
                           Senescent.
Juvenile:                  A young tree, given normal environmental conditions for that tree it will not
                           yet flower or fruit.
Semi-mature:               Able to reproduce but not yet nearly the size of a mature specimen in that
                           location.
Mature:                    Has reached or nearly reached full size and spread for that species in the
                           given location.
Senescent:                 Old age: health and / or structure is being adversely impacted by the ageing
                           process.
AMENITY VALUE              A judgement of amenity and utility the tree provides - primarily based on
                           the trees visual contribution to the neighbourhood. Other contributing
                           factors include species, size, age, health and ecological value. Amenity
                           value does not consider the degree of risk associated with a tree. Trees on
                           neighbouring properties should be protected (unless otherwise negotiated
                           with the owner) regardless of the amenity value
CANOPY SPREAD              Overall size of the canopy as looking from a plan view. Recorded at the
                           widest point.
CO-DOMINANT                Two stems of approximately the same thickness and height originating from
STEMS                      the same position in the tree.
COMMON NAME                A non-scientific name commonly used for that tree.
CROWN WIDTH                See ‘Canopy spread’
DBH                        The diameter of the trunk measured at or near 1.4m above ground level.
(Diameter at Breast        Where there is more than 1 stem originating below 1.4m the measurement
Height)                    recorded is calculated as described in AS 4970-2009 for multi-stemmed
                           trees.
DEAD                       Cessation of all metabolic processes (or very soon to be)
DEFECT                     An imperfection, weakness, or lack of something necessary. In trees, defects
                           are injuries, growth patterns, decay, or other conditions that reduce the tree's
                           structural strength.
DTW                        The distance (in metres) from the proposed works to the centre of the trunk
(DISTANCE TO               at the base of the tree.
WORKS)
FORM                       Reference to the symmetry of the crown as observed from all angles and in
                           accordance with the morphology of that species, and documented as Poor,
                           Fair or Good.
HEALTH                     A trees vigour as exhibited by the crown density, leaf colour, seasonal
                           extension growth, presence of stress indicators, ability to withstand diseases
                           and pests, and the degree of dieback. Where a deciduous tree is inspected
                           without foliage and health is undetermined ‘?’ will be recorded.
