THE
TOOLS OF PRESERVATION: DOCUMENTATION AND MONITORING
As
the international preservation field has matured from years of ICOMOS and World
Heritage learning experiences, monitoring site conditions has assumed an
increasingly prominent role. It is understood that the preservationist's
ultimate task of ensuring the conservation of the material cultural heritage
hinges not only on treatment but also on the documentation and monitoring
process.
The
tasks involved in monitoring are variable, depending on the needs of the site,
and the specific objectives of the effort, but the underlying foundation for
the entire monitoring process is documentation. Documentation and monitoring
are often treated as the same activity or as being inextricably interwoven,
when in fact they are complimentary but separate. Driven by different goals,
each one requires different skills and results in a different product.
Documentation
is subjective, in that it is undertaken from a particular point of view, but it
is most importantly a descriptive, non- interpretive process that gathers and
records observable facts in order to establish a base-line against which to
assess change. On the other hand, monitoring is an analytical and critical
process of comparative evaluation of conditions existing at a point in time
with the base-line data acumulated in the documentation process, with the
objective of determining physical evolution in the historic fabric.
Documentation
can help define the significance and integrity that contribute to official
recognition of a site's importance. At its best and most useful, documentation
is more than that: it is an ongoing process that periodically records the
physical status of the site in accordance with consistent methodology.
Site
stewards are handicapped without this type of documentation when diagnosing
existing site conditions, and may be led to the wrong conclusions and
diagnosis, leading to overly aggressive or inappropriate treatments. For
example, if a surface condition appears suddenly and worsens daily, one
approach may be correct; if the condition has been completely stable for 20
years, that approach may be disastrous. Only good documentation can support
this analysis. A well-planned photographic archive spanning fifty years is an
unbeatable monitoring tool for clearly identifying types of deterioration and
their progression over time. Linked to other methodical recording (regularized
intervals, fixed observation posts, testing procedures, etc.) of climate,
treatments or visitation, the documentation archive provides the firmest base
for sound monitoring interpretation of condition and diagnoses.
Monitoring
guidelines are beginning to be formulated and tested for World Heritage sites
by various regional consortia around the world. A prototype was developed by
the UNDP (Southern Cone), and a model mission was designed and commissioned by
ICOMOS Sri Lanka. While the process of monitoring varies depending on the
objectives or the type of information sought, the process of base-line
documentation in this context more easily lends itself to standardization.
Because of its perceived similarity to "auditing," monitoring by
outside experts can be perceived as threatening to the owners, who may view
monitoring suspiciously -- as foreign intervention with a potential for making
local administrators appear negligent or incompetent.
Documentation
work, however, has not yet been the subject of good, economical and
straightforward guidelines within the World Heritage context. While each site
or site type may require specific adjustments to the "perfect site
archive," the best process of periodic observation and documentation is
often most effective and user-friendly when it is low-tech and relies on
relatively inexpensive recording methods, such as black-and- white photography,
simple measurements and standardized field forms.
Developing
such a set of guidelines is the point of a collaboration between the Getty
Conservation Institute and the World Heritage Centre. They are starting by
examining the range of needs on site, identifying a set of interested test
sites, creating a set of recording strategies, and discussing with Earthwatch
the possibility of their support for a set of low-cost, well-organized
recording projects. The intended results are well-described, economical,
responsive, tested options for recommendation to the World Heritage site
managers interested in creating useful documentation archives to support site
management and conservation.
