Heritage trees are individual trees
of any size or species that are specially designated
as heritage because of their historical, commemorative,
or horticultural significance. The list of designated
Heritage Trees remains open for new designations
and provides useful information to Department
of Recreation and Parks staff regarding the importance
of their actions while planning activities near
heritage trees.
In January 2004, the Department began the inventory
of an estimated one million trees in City Parks
using a system that provides detailed information
on tree species and the value of its characteristics
in relation to active and passive recreation,
its cooling/shading effects, as well as its ecological
and financial benefits. Global Positioning System
(GPS) using satellites is utilized, which is able
to record the location of park trees with an accuracy
of less than 12 inches. Recorded GPS information
is transferred onto a Geographic Information System
(GIS) ArcView map. Field collected data is then
enriched with information entered into the Data
Base, which is linked to the individual tree species.
Combined information is then sent to the GIS Division,
Bureau of Engineering, Public Works Department
that you can view on NavigateLA.
Staff has completed the inventory of one of the
most valuable tree categories in City parks -
the Heritage Trees. We invite you to print the
map and visit our parks to enjoy our unique trees.
The tree inventory is also used in the Department
in offering nature related programs to schools
and to the public.
