Environmental targets are often used in planning for sustainable agricultural landscapes but their impacts are rarely known. In this paper we introduce landscape futures analysis as a method which combines linear programming optimisation with scenario analysis in quantifying the environmental, economic, and social impacts associated with achieving environmental targets, on a landscape scale. We...

Forest management often has cumulative, long-lasting effects on wildlife habitat suitability and the effects may be impractical to evaluate using landscape-scale field experiments. To understand such effects, we linked a spatially explicit landscape disturbance and succession model (LANDIS) with habitat suitability index (HSI) models to assess the effects of management alternatives on habitat s...

Classical conservation approaches focus on the man-made degradation of ecosystems and tend to neglect the socialecological values that human land uses have imprinted on many environments. Throughout the world, ingenious land-use practices have generated unique cultural landscapes, but these are under pressure from agricultural intensification, land abandonment, and urbanization. In recent years...

Intensity and type of management, the cultural variable shade, and the combination of woody and herbaceous annual and perennial plants were evaluated for their effect on key landscape arthropod pests. Azalea lace bugs, Stephanitis pyrioides (Scott), and twolined spittlebugs, Prosapia bicincta (Say), were most effectively suppressed in landscape designed with resistant plant species of woody orn...

While significant progress has been made on the modification of crops for the benefit of producers, the same cannot be said in regards to eliciting the potential impact that these crops may have on the wider landscape and the diversity of life therein. Management impacts can create difficulties when making policy, regulation and licensing decisions in tho...

In the socioecological landscape planning of natural resources, as presented in this article, sociocultural and ecological decision criteria are considered with ‘traditional’ timber production analyses in an integrated and holistic way. As the main phases, the approach involves: pinpointing sites that are important with respect to management objectives related to ecological or sociocultural con...

The relationship between landscape patterns and functions is the central research theme of landscape ecology and forest management. This study assesses the interactive relationship of landscape heterogeneity with the carbon stock of urban forests in the city of Xiamen, Fujian Province, China, using spatial and statistical analyses. The objectives of this study are to explore the most appropriat...

• What is the range and pattern of variability in landscape structure under “natural” and anthropogenic disturbance regimes? RMLANDS provides a mechanistic approach for evaluating disturbance and succession processes over broad spatial (100,000's of ha) and temporal scales (100's of years) not possible or practical with empirical field studies. Moreover, RMLANDS allows us to ask “what if” quest...
