This
comprises an assessment of specific trees, often in response to
pereceived problems. Such trees might, for example, have visible
cavities or fungal brackets on their trunks or structural characteristics that may predispose them to failure. These surveys usually involve the use of specialist decay detection equipment and/or climbing the trees in question. APArboriculture
has access to the latest decay detection devices, including a
Resistograph F400 Decay Detection Drill and a PICUS Sonic Tomograph. Click here for a sample Specific Tree Survey Report. |

This
type of survey entails comprehensively surveying all of the trees
within a site and recording details of each tree (and any tree works that
may be required) in a Tree Survey Schedule. Each tree is tagged using a
low invasive Latschbacher tag, which serves as a reference for future
surveys. The locations of the trees are also shown on a Tree Location Plan. The
advantage of this type of survey is that it provides a definitive
record of all of the trees within the site for subsequent management purposes.

As with a Comprehensive Survey, a Negative Reporting Survey involves
inspecting all of the trees within a site. The difference in this case
is that only those trees for which works are required are tagged (using
low invasive Latschbacher tags), recorded in a Tree Survey Schedule and
shown on a Tree Location Plan. This type of survey can be recommended
in many situations as it will be less costly than a Comprehensive
Survey and is an accepted method of surveying trees (including by the
Health & Safety Executive). Click here for a sample Negative Reporting Survey Report. |
