To facilitate operations, a property may be divided into discrete management
zones. These zones are sometimes defined during the Cultural
Landscape Report process and are typically based on historically defined
areas. Alternatively, zones created for maintenance practices and priorities
could be used. Examples of maintenance zones would include woodlands, lawns,
meadow, specimen trees, and hedges.
Training of maintenance staff in preservation maintenance skills is essential.
Preservation maintenance practices differ from standard maintenance practices
because of the focus on perpetuating the historic character or use of the
landscape rather than beautification. For example, introducing new varieties
of turf, roses or trees is likely to be inappropriate. Substantial earth
moving (or movement of soil) may be inappropriate where there are potential
archeological resources. An old hedge or shrub should be rejuvenated, or
propagated, rather than removed and replaced. A mature specimen tree may
require cabling and careful monitoring to ensure that it is not a threat to
visitor safety. Through training programs and with the assistance of preservation
maintenance specialists, each property could develop maintenance specifications
for the care of landscape features.
Because landscapes change through the seasons, specifications for ongoing
preservation maintenance should be organized in a calendar format. During
each season or month, the calendar can be referenced to determine when,
where, and how preservation maintenance is needed. For example, for some
trees structural pruning is best done in the late winter while other trees
are best pruned in the late summer. Serious pests are monitored at specific
times of the year, in certain stages of their life cycle. This detailed calendar
will, in turn, identify staff needs and work priorities.
Depending on the level of sophistication desired, one approach to documenting
maintenance data and recording change over time is to use a computerized
geographical or visual information system. Such a system would have the
capability to include plans and photographs that would focus on a site's
landscape features.
If a computer is not available, a manual or notebook can be developed to
organize and store important information. This approach allows managers
to start at any level of detail and to begin to collect and organize information
about landscape features. The value of these
maintenance records cannot be overstated. These records will be used in
the future by historians to understand how the landscape has evolved with
the ongoing care of the maintenance staff.
