Geographic Information Systems Applications in Natural Resource Management Chapter 12 Synthesis of Techniques Applied to Advanced Topics Michael G. Wing & Pete Bettinger

Chapter 12 Objectives How a set of complex management rules or assumptions can be synthesized into quantitative information that can be used in a GIS analysis; How a number of GIS processes can be integrated to allow you to develop a spatial representation of a value (ecological, economic, or social) that represents some aspect of a landscape; and How ecological, economic, or social descriptions of a landscape can be developed to provide managers and other decision-makers with information regarding the current status of a landscape.

Chapter 12 Builds on the tools and techniques that were introduced in chapters 5-11 Wraps them into three applied problem examples  Land classification  Recreation Opportunity Spectrum  Habitat suitability model with a road edge effect Demonstrates examples of how techniques from previous chapters can be used in applied settings

Land classification Land classifications have many purposes in forestry and natural resource management  Guideline for resource inventorying  Framework for assessing management opportunities  Provide policy direction (knowing what resources are available)  Assist with policy implementation (knowing where resources are located) Land classifications are generally based on land characteristics that can be seen and measured Most natural resource organizations establish their management plans within a land classification framework

Developing a management plan One of the first steps is to describe the resources (land) to be managed and the types of management activities that will be appropriate for each part of the land base After land classification, the goals and strategies for management can be planned and implemented  Management plans may restrict certain activities from some areas, concentrate activities in other areas, or allow a full range of silvicultural and operational activities in the remaining areas

Land classifications for membership Land classifications may also be used as a requirement to participation in some stewardship programs The American Forest & Paper Association (industrial forest organizations mainly) requires that members comply with the Sustainable Forestry Initiative (SFI)  The SFI requires classification of lands according to the SFI land classification system

Oregon State Forest Land Classification System Three main categories organized into an order of precedence  General stewardship Most silvicultural and operational activities allowed  Focused stewardship A limited set of management activities allowed Can’t be reclassified as general  Special stewardship Very few forest management activities allowed Can’t be reclassified as focused or general Categories can’t overlap spatially  This implies that GIS database development should start with the most restrictive category (Special stewardship) and work toward the most general May need a series of query, buffer, clip, and erase operations to get to the final land class

Land classification: Brown Tract Class 1: (reserved) areas will contain meadows, research areas, rock pits, and oak woodlands. Class 2 (limited management) will be those areas of land that are within 50 m of streams, 100 m of hiking trails, 100 m of homes, and 300 m from any owl nest locations. Class 3 (general management) areas are assumed to contain land that remains after class 1 and class 2 management areas have been delineated.

Classification procedure The spatial rules for Class 1 and 2 could be applied to create GIS databases of associated areas A Class 3 GIS database could be created by erasing Class 1 and 2 areas from the Brown Tract Vegetation GIS database Erase process Erased GIS database Erase process Class 3 stewardship GIS database Class 1 stewardship GIS database Class 2 stewardship GIS database See Figure 12.2 for a flow chart of GIS processes that would support the creation of Class 1 and 2 areas

Brown Tract Land classification Class 1 Class 3 Class 2 The sum of the three areas should equal the total area or  An overlap exists  Some area of the landscape has not been classified

Recreation Opportunity Spectrum Developed by the USDA Forest Service as a tool for managing recreation and tourism on federal land and also for integrating these activities with other land uses The ROS is used to describe and identify recreational settings  Describes the likelihood of recreational opportunities along a spectrum which is divided into several categories that combine aspects of location and access  An opportunity is an area that may yield certain experiences

Primitive (P)Areas of land greater than 1.5 miles from a road. Semi-primitive, Areas of land which are greater than 0.25 miles from a road,non-motorizedhave forest stands  50 years of age, and are  (SPNM)hectares (500 acres) in aggregate size. Semi-primitive, Areas of land which are greater than 0.25 miles from a motorized (SPM) paved road, have forest stands  50 years of age, and are  hectares (500 acres) in aggregate size. Roaded natural (RN) Areas of land with stand ages  50 years, and  16.2 hectares(40 acres) in aggregate size. Roaded, managed (RM) Areas that do not fit into any of the other classes.

Habitat suitability model with a road edge effect Habitat suitability models provide managers with a glimpse into the potential of a landscape to support habitat for specific wildlife species These models generally take the geometric mean of two or more variables that represent or influence the occurrence and abundance of a particular wildlife species While some debate exists as to their usefulness and accuracy, habitat suitability models do allow managers to examine the relative quality of one area versus another with respect to a particular species

Habitat suitability index (HSI) HSI = f (basal area, age, distance from roads) HSI calculation = (basal area score * stand age score * distance from road score) 1/3 Values must be assigned to each variable based on research, literature searches, professional advice, field data, or other means
