Relative Wilderness of the Chesapeake Bay Watershed
Entry ID: Relative_Wilderness_Chesapeake


Summary
Abstract: Relative wildness of the Chesapeake Bay watershed. A combination of
data representing the six attributes of the land that contribute to
its wildness. These attributes are solitude, remoteness, uncontrolled
process, natural composition, unaltered structure, and pollution. For
a full treatment of the wildness concept see "Indicators of Wildness:
Using Attributes of the Land to Assess the Context of Wilderness" in

This data for the Chesapeake Bay watershed is produced as a part of a
TWS effort to define the concept of wildness in a manner that allows
its mapping. This effort is undertaken in support of our strategic
goal of supporting the creation of a national network of
wildlands. The wildness concept offers a new way in which to look at
landscapes. It demonstrates that wildness is a continuum, that it is
relative to the landscape being examined, and that it is present in
all landscapes -- large and small, urban and undeveloped. The data not
only allows for the creation of hard copy and digital maps of relative
wildness in a landscape, it can be used as input to other processes in
which wildness may have meaning.

The wildness concept, as developed by The Wilderness Society, embodies
subtleties it is important to understand so that wildness mapping data
is not inappropriately used or interpreted. While review of the
conceptual paper referenced elsewhere in this metadata provides
information necessary for proper understanding, that paper does not
address some of the subtleties discovered during our development of
the mapping process subsequent to that paper's writing. Following is
an attempt to highlight some of the more important of these
subtleties.

Our wildness index is a unitless relative rank--ordinal data in
technical language. It does not show wildness in any absolute
sense. There is no zero wildness, and a rank of 30 is not twice as
wild as a rank of 15. From this fact stem several others.

Quality
Computing relative wildness involves assigning nominal (rank) values
to source data, then summing those ranks. We recognize that
mathematical summation is strictly not appropriate for nominal
data. We utilize this technique for lack of a reasonable
alternative. A review of conservation research literature shows that
this is a commonly used technique, so we are, at least, in good
company in our inappropriateness.
