CAN RAPID BUFFER ASSESSMENT AND LAND USE INDICATE WETLAND FLORISTIC QUALITY AND TAXONOMIC DISTINCTNESS?
Freshwater biological integrity is continuously threatened by human activity. Impacts to biological health may be inferred directly (i.e. bioassessment), or estimated indirectly using rapidly assessment or computer-based data layer analysis. This study tests if rapid buffer assessment and surrounding land use can predict and classify wetland biological health as represented by floristic quality (FQ) and taxonomic distinctness (TD). From surveys of 106 non-forested wetlands in Oklahoma, we found a limited ability for land use and buffer quality to estimate site-specific FQ values. Similarly, land use was not a reliable predictor of site-specific TD values. Predictive ability improved with ecological stratification, but linear relationships remained weak. There were also high misclassification rates of FQ and TD. However, limited land use had potential to identify higher levels of FQ, and more intensive land use showed potential to identify lower average TD. This suggests that both measures (FQ and average TD) are needed for a more complete classification of wetland biological response to anthropogenic disturbance. Despite growing interest in relatively rapid or low-cost methods of wetland assessment, our results do not support using such methods in lieu of direct bioassessment.
