Using geographic information system analysis and digital image simulation software, varying extents and configurations of natural vegetation are integrated into the small-grain farming landscape of Whitman County, Washington. The capacity of these landscape-scale buffer systems to enhance ecological function by reducing soil erosion rates and improving water quality is measured with the Water Erosion Prediction Project model. The influence of the alternative landscape scenarios on aesthetic preference is measured by residents' scenic quality ratings of the simulated scenes presented in a mail survey questionnaire. Results reveal a statistically significant, positive relationship between landscape preference and landscape structure indicative of improved ecological function. Thus, the visually perceptible structural attributes of agricultural landscapes can provide an accurate and coincident indication of both ecological function and aesthetic quality.
