Abstract:
This information was created by attributing the 2005 landuse layers for the study areas of each county
with point values.
URS developed a simple system to assign a “preservation weight” to each potential
preserve area. Various factors were identified and a ranking system was developed
allowing us to rank the factors on scales of 1 to 4 or 1 to 5.
Factor 1: Size Class
The first factor assessed was size. A size class scale was developed to rank areas:
1 to 24.9 acres = 1
25 to 49.9 acres = 2
50 to 99.9 acres = 3
100 or more acres = 4
Factor 2: Connectivity
Connectivity was assessed. Connectivity is the degree to which a path is connected to
other patches of similar composition. A forest patch that is surrounded by other forest
patches has very high connectivity. Conversely a wetland surrounded by farm field has
no connectivity. Connectivity was assessed by treating each patches as a square, and
assessing the number of sides that touched a similar community. Thus a patch of forest
that touched another forest on two sides, and farm fields on the other two sides, had a
connectivity score of 2.
Factor 3: Edge to Interior Ratio
Edge to interior ratio was calculated. The resulting ratios were then ranked on a scale of
1 to 5 such that:
Ratios < 1 = 5
Ratios > 1, < 2 = 4
Ratios > 2, < 3 = 3
Ratios >3, < 4 = 2
Ratios > 4 = 1
Factor 4: Edge Shape
The shape of an area was considered. One way to express the complexity of a perimeter
is to measure how far that shape deviates from a circle of the same area. The formula for
this comparison is:
Where:
R = a dimensionless quantity representing the deviation of the shape from round.
p = the perimeter length
A = the area of the shape.
R will vary from 1 in a circular shape, to infinity for a very long and narrow shape
(approaching a line). Output from this formula was ranked on a scale of 1 to 5:
R < 2 = 5
R > 2, < 3 = 4
R > 3, < 4 = 3
R > 4, < 5 = 2
R > 5 = 1
Factor 5: Stream Buffer
Finally, each potential preserve area was given an extra point if it might function as a
stream buffer. This was assessed by creating a computer command that identified all
those potential preserve polygons that touched a stream edge. If the polygon was
adjacent to a stream, it received a score of 1 for this factor. If the polygon was not
adjacent to a stream, the score was 0.
A final preservation priority score was developed by summing the 5 preservation factors.
Finally, these factors are displayed individually with each polygon. This enables future
users to comment and compare their preservation/restoration value and to change values
based upon new factors.
Also, to help deciver these areas on a map, a ranking system was created with low,
medium & high quality of opportunity. The ranking is as follows:
Low = below 7
Medium = 7.01-12
High = above 12

Resource_Description:
This project was funded in part by a Great Lake Coastal
Restoration Grant (GLCRG) supported by th eNational Oceanic
and Atmospheric Administration (NOAA) through the Ohio
Coastal Management Program (OCMP).
The North Coast Regional Council of Park Districts (NCRCPD)
received a Great Lakes Coastal Restoration Grant in 2003
that would provide funding to promote regional planning and
management in the multiple counties of the North Central
Ohio Lake Erie Watershed (Lorain, Erie, Medina, Huron,
Ashland, Seneca, Ottawa, Wood, & Sandusky counties). The
grant project, which is just Phase 1, includes:
" A regional clearinghouse of natural resource information
" A landuse classification system for detailed analysis
" Scientific quantifiable methodology to pinpoint critical
tracts of land required for preserving & restoring water
quality in Lake Erie
" an interactive, public internet mapping web site that
would enable other agencies to produce custom mapping for
future funding
" provide a regional planning tool to reduce duplicity
" create a platform for future data management and review
by the public & other agencies
This documentation is the final product of that Phase 1
project. Additional funding is being sought to include more information.
