The degree to which biodiversity can be increased without subsequent reduction of agricultural production is a major objective for agriculture land systems research. Several new technologies have developed over past decade that may enhance landscape ecological experimentation including remote sensing with unmanned aerial vehicles (UAVs) and with bioacoustic recording. This presentation will characterize farmland heterogeneity in vegetation and avian species richness by examining relationships between agricultural landscapes and soundscapes. Heterogeneity of semi-natural vegetation cover will be characterized using multi-temporal imagery acquired using consumer-grade cameras deployed on a UAV. Agricultural soundscapes will be observed using low-cost bioacoustic recorders. Acoustic indices are described and proposed as a proxy for avian species richness. A correlation between soundscapes and landscapes has been proposed, but there are few studies that have attempted to test this. This presentation addresses this challenge with a new case study from farm level analysis in the US Midwest. Understanding how landscape configuration, and composition lead to higher species richness is agricultural landscapes would help to test the effectiveness of conservation interventions in agricultural landscapes.
