I teach biology at Hillsdale College. I use the survey markers to mark trapping grids. My students and I trap small mammals (mostly native mice) and record demographic data and collect tissue for DNA analysis. Our grids are usually laid out so that each station (each survey marker marks a station) is 20m from the others. We place a trap or two at each station. I will trap 3 – 4 times a year for, I hope, several years. In the past I have used wooden stakes, but wanted to try something different. So far we really like the survey markers. They go in the ground easy and are easy to find. A few were run over by a 4-wheeler and were not broken.
