Combining the Recreation Opportunity Spectrum (ROS) and Geographic Information Systems (GIS) to assess current and future recreation conditions in Oregon's coast range

by Rogan, Lael M.

Abstract (Summary)
Conflict over the best way to manage Oregon's public lands makes a land

planner's job extremely challenging. Multiple uses, federal mandates, and

constantly evolving knowledge all contribute to the difficulty of determining how to

best use the land. The Coastal Landscape Analysis and Modeling Study

(CLAMS) was developed in 1994 to help policy makers better evaluate potential

land management plans and to examine the effects and interactions of

ecological, economic, and social models on a regional scale. Geographic

Information Systems (GIS) are used in CLAMS to simulate and demonstrate the

spatial effects of alternative policies. The dynamic nature of land use and

planning lends itself well to GIS, a powerful computer-based tool that can

expediently illustrate different management scenarios.

One component of CLAMS focuses on social aspects, including

recreational use of forestlands. In 1997, a prototype model for assessing the

amount of recreation habitat was developed in the Coos Bay (Oregon) Bureau of

Land Management (BLM) District. The study served as an inventory for

recreation planners to identify the existing recreation opportunities. Geographic

Information Systems and the Recreation Opportunity Spectrum (ROS) were

combined in order to determine acreage of different recreation habitat types, or

ROS classes.

My project incorporates many features of the Coos Bay study (combining

GIS and ROS) but extends the geographic boundaries to include most of the

Oregon coast range. It also extends the analysis by integrating the recreation

model with a landscape change model7 to show how recreation opportunities

would change over a 100 year simulation of landscape conditions. It will provide

land planners and recreationists with information about the scope of recreational

experiences that they can expect to find in this geographic area.

Results illustrate that the greatest proportion of land falls into the

recreation category with the most developed or modified landscapes, and th.e

smallest quantity of land is at the primitive end of the spectrum. This holds true

for current and future conditions. These results are not surprising, given the

large degree of human modification in the CLAMS study area.

Collecting and generating spatial data offer immediate and long-term

benefits. They not only provide an inventory to land managers, but also help

fulfill CLAMS goals by examining the effects of land change over time.
