social functionality, social survey methods, social functionality
This study seeks to explain and understand what is important to and motivates landowners of rural, non-industrial private forests (NIPFs). The amount of forest in the Michigan study areas is increasing, mainly because of a change in who is buying these lands. A mail-survey is used to assess the motivations behind ownership of these NIPFs. Results indicated that aesthetic reasons and environmental protection ranked highest among landowner reasons for retaining forest on their lands, economic benefits ranked 3rd. 'Wildlife habitat' and 'add beauty' were the highest rated individual items. While the overall trend was the same for both groups (1.aesthetic/2.environmental protection/3.economic) farmers rated economic reasons higher than non-farmers. The survey also explored owners views, effortsand knowledge about management of these areas. It is another good social survey source both in terms of examples of results/questions and for refs and methods of developing survey; also interesting for results--ranking of motivations, but may be very different in an area closer to lg city (or in the study site in 20yrs). It also highlight benefits/importance of private forest patches.

This paper presents a hedonic price model for residential property in the Washington DC area. The researchers used spatial data from a GIS datavase to develop landscape indices to include in this mode, specifically the diversity and fragmentation indices within a 0.1 and 1.0 km radius. The analysis indicates that within a 0.1 km radius, the effect of percentage open space is significant and positive, but within a 1.0 km radius, the effect is significant and negative. The authors suggest that the latter effect is due to the absence of urban services. In the larger buffer, forestry and agricultural uses also tend to decrease propert values.

Abstract only, article in press. Method of integrating census data with urban green space data should be worth looking at.
The objective of this ongoing research is to analyse the social potential of urban green spaces to create opportunities to integrate youths, elderly people, foreigners, unemployed and other social groups into the urban life of large Swiss agglomerations. Urban green-space data are linked with social demographic datat for these particular social groups. Three large cities in the different language regions of Switzerland have been selected for a comparative study: Geneva (French-speaking), Lugano(Italian-speaking) and Zurich (German-speaking). The green-space data derived from vector25, the digital landscape model in a vector format of the Swiss Federal Office of Topography, and the social demographic data from the 1990 Swiss census are compiled for further processing with the geographical information systems ArcInfo and ArcView. In this way, a contribution to the development of a GIS-based research methodology is made. The goal of this approach is to obtain a highly aggregated planning tool for urban forestry and green-space development.

A good account of the history of 'urban ecology' and how its roots began at the same time as plant and animal ecology but was primarily viewed apart from it 'human ecology'. Authors now stress move back to this linkage but considering humans as one would any other social creature. Case is made that neither strict 'ecology' approaches nor straight sociological approaches are adequate to answer urban ecology questions, a middle-ground or combination of the two are needed. One example question is very similar to our research interests. The article is a good source for theory and background sort of a justification/history of urban ecology approach. As mentioned above, one of their example ?s is very close to what we are trying to do. They also provide examples of how different info can be meshed together using gis (nothing earth shattering); my favorite quote: 'However, a common confusion among many life scientists who do not study people or other social species is that measurements of human communities are difficult if not impossible....' so take heart DAJA!

This is really an article that only peripherally applied to our project. It breaks societal factors down into ownership, use and control of resources, and policy. Societal drivers are another category that includs values, technology, economy, population, and institutions. A third category is 'quality of life' that deals with access, income, employment, and the willingness of the public to live in a 'low impact' manner. The article is really aimed at the assessment of restoration efforts and potential in Florida. Therefore, the aim of the study differs from ours. The value comes in the way in which the factors affecting restoration are organized and identified.

As obvious as it seems, it is a good thing to keep in mind when you begin using data in more abstract manners.

It provides a general description of complex systems and argues that complexity theory is an appropriate framework within which to examine urban systems. " a conception of the social, political, and economic world as a complex, self-organizing, adaptive system, parallel to those being identified in the physical and biological sciences, .." California is used as an illustration of the complexity of urban systems and to illustrate the limitations of current/past approaches. It includes a limited literature review. The article ultimately takes a final step arguing that complex systems provide new insights to sustainability. The application of the framework is broken into 3 parts: indicators (system indicators, performance measures, rapid feedback), consensus building, and leadership. The application ideals are just that, Ideal. While good points are brought up, they are not terribly practical. Other articles may be better descriptions of complex systems.

This paper describes efforts to use LandSat Thematic Mapper data to identify landcover classes. Landcover for the greater Chicago area is then inventoried, paying particular attention to urban vegetation. Methods for classifying and utilizing LandSat TM data are described. Also discusses the successes of forest preserve systems for retaining forests in highly urbanized, high density communities. Also correlate landcover data with household number and income data, nothing shocking found--i.e. amount of forestland inversely related to number of households. Overall, it is a good remote sensing method paper and example of the type of work we might need to do. Findings of interest or relevant to our study include that wealthy regions had higher tree cover while poorer had lower tree cover.

The authors present findings on and describe methods for measuring stakeholders opinions/values in how they think about certain issues, in this case human dimensions of forest management. The 3CM method of cognitive mapping is used to evaluate how 3 different stakeholders in forest management view this topic. Three human dimensions were common to all stakeholders although how each defined these dimensions differed. Of note is the fact that social cycles, community well-being, and social stability (i.e. Sense of Place/Community) did not emerge as 'salient concepts in the view of forest stakeholders. It is a good illustration of the use of cognitive mapping, probably not what we want to do. However, results are interesting and of some note to us: idea that no mention of sense of place type concepts emerged from stakeholders and that these concepts are not widely considered or understood outside of academia and therefore will have little influence over decisions. Also a nice discussion of switch in management direction from solely resource production to managing for multiple values (in intro)

This paper discusses the benefits of forest patches in urban areas. The primary focus is on exploring the services trees provide: removing pollutants from the air, carbon sequestration, and energy saving for building (heating and cooling costs). A cost/benefit analysis found that the cost of tree planting and care were outweighed 2:1 by the energy saving benefits they provided. This paper offers some interesting views of the functionality of trees and converts the heating/cooling/pollutant removing/carbon sequestering functions of trees to a dollar value. While this is not necessarily what we want to do, considering these services is worth talking about. Use data from the Northeastern Illinois Planning Commission for socioeconomic variables--do we have a similar source besides census data?

The authors of this paper used GIS data to estimate the visibility of certain types of land cover from parcels of property in Simsbury/Avon, CT. This information was incorporated into a hedonic regression, to assess whether visibility of certain cover would have an impact on the sale price of a house. Although the explanatory power of the model did not increase with the addition of visibility into the model, some of the visibility variables did appear to be significant. Most surprising, however, was that a view of forested lands in the model was negatively correlated to housing price.

An issue with hedonic price models is that the housing market often exhibits slow adjustments to system shocks. In addition, the resulting changes in other systems, such as the labor market, can induce further changes in housing prices over time. As a result, the effects of certain changes on housing prices may vary over time. This paper details the efforts to link models of housing and labor markets together for the Boulder, CO area. The results demonstrate that feedback within the system changes the apparent effect that preserved greenspace will have on housing values over time.

Surveys were conducted in communities in southwest VA to assess these models. Two models are discounted: that meditative effects lead to contentment with a neighbourhood and consequently, with one's own life; and that quality of life is addressed through hierarchical effects, from neighbourhood to housing to home to personal satisfaction. The model that is supported is that both satisfaction with community and housing satisfaction relate to life satisfaction.

This effect was also observed for developed parcels, but the effect was not as strong.

This article assesses the benefits of urban forests in Joensuu, Finland, with the use of the contingent valuation method (CVM). Issues regarding the use of surveys to identify preferences and willingness to pay are discussed. The research concludes that while willingness to pay changes with season, area and location, residents are willing to pay for the use of forests, and are also willing to pay to prevent the conversion of forests to other uses. This may differ, however, based on environment and cultural values.

Geographic gradient of urbanization pressure, or demand for land, was calculated using splining based on "distance-decay" and "retail gravity" theory. Basically they built a surface map of urbanization pressure based on the population:distance ratio from multiple urban centers. This gradient was 'moderately' correlated with forest fragmentation (grid analysis) and 'strongly' correlated with land-cover change (NDVI). They speculate that forest pattern was also influenced by local and historical factors (unexplained variation). The building of a geographic gradient might be a useful technique.

The argument is made that complex systems are hierarchically orbanized. This leads to two key points: (1) a focal level can be defined; and (2) once a focal level is defined the relevance of other time/space processes can be determined. Another strenght of this article is the fact that the theory is applied as part of the Pheonix LTER. It explains how the theory is used to build and relate models and how patch hierarhcies are defined and scales changed.

This article provides a good review of complex systems theory. It takes the ideas further than Innes and Booher (1999), in that it adds the concepts of hierarchy and patch dynamics. The argument is made that complex systems are hierarchically organized. This leads to two key points: (1) a focal level can be defined; and (2) once a focal level is defined the relevance of other time/space scale processes can be determined. Another strength of this article is the fact that the theory is applied as part of current research in the Phoenix LTER. It explains how the theory is used to build and relate models and how patch hierarchies are defined and scales changed.
