If you don’t measure it, you will be hard pressed to verify that you have improved it.
One of the most basic tenets of improving anything is measuring the thing — recording changes over time. This also applies to pasture health. Last year I began taking a picture of one part of my pasture every month, near the first of the month. While it will generally show variations in forage over the seasons, it will eventually illustrate improvements over the years with regenerative management.
Please note that the timestamp on the camera is incorrect until November, 2021. The camera is an inexpensive eastern model that limits my ability to manage it.
Unfortunately, I missed July, 2020. The difference between June and August is significant.
