Rapid Wetland Quality Assessments Possible With Streamlined Approach

By tweaking the way that an assessment tool is used, researchers at Penn State University have found that it can reveal wetland quality in a faster but just as accurate way, according to a release. The tool in question is the Floristic Quality Assessment (FQA), commonly used to judge the quality of a wetland, taking into account the health and abundance of its plant species.

Though typical approaches using the FQA rely on a complete list of a wetland’s plant species, Penn State scientists wanted to see if there was a quicker but still reliable way they could fill in that part of the assessment. So instead of a complete list of plants in a wetland, they tried just using a list of the dominant species within.

This approach was applied to 87 of 200 wetlands that are monitored by Riparia, a research effort supported by the university, revealing that this rapid version is just as effective at predicting the quality of a wetland. The researchers later took the findings and used them in creating an online calculation tool that lets anyone monitor the quality of wetlands based on a list of existing flora in an area.
