Conducting Vegetation Surveys Using Geotagged Photographs from Smartphone and Unmanned Aerial Systems

J. S. Glueckert, A. E. Riner, James Leary, James Leary, K. L. Gladding, yEli C. Russell

This publication aims to describe a simple method of importing and displaying geotagged images from unmanned aerial systems (UAS) or smartphones as vector symbols that are scaled and oriented to co-register with base layer maps in a geographic information system (GIS) without the need for processing into an orthomosaic. Instructions in this publication are for QGIS, version 3.28 LTR, but can be easily transferable to other GIS software. These methods offer an efficient and effective way to view high-resolution aerial images and photo-point image surveys in a GIS environment, allowing for basic analysis such as annotating features or points of interest. Written by J. S. Glueckert, A. E. Riner, J. K. Leary, K. L. Gladding, and E. C. Russell, and published by the UF/IFAS Department of Agronomy, February 2026.

Are the Herbicides That We Use in Aquatic Systems Considered PFAS?

Eli C. Russell yJoseph H. Bisesi

In the environmental science community, there has been increasing concern and emphasis on a relatively new designation of molecules called per- and polyfluoroalkyl substances, also known as PFAS. These compounds are colloquially referred to as “forever chemicals” due to their potential persistence in the environment. Recent concerns have arisen regarding aquatic herbicides and whether they are classified as PFAS. The purpose of this publication is to provide information on aquatic herbicides and their classification as PFAS, enabling all stakeholders involved with aquatic environments to gain a deeper understanding of the herbicides used in their water bodies. Written by Eli C. Russell and Joseph H. Bisesi, and published by the UF/IFAS Department of Agronomy, September 2026.
