What is Biological Monitoring? A method used consistently to read the land. It will give you valuable insight, basic information and data to know how to work the land. Soil surface is key. The earliest changes on any piece of land are most likely to occur at or near the soil surface, but this is particularly so on land that has been reduced to a high percentage of bare ground. Changes could show up in plant spacing, soil litter cover, soil density, soil aeration or organic content, insect activity, seedling success, quality of water runoff, and a host of other things. Bi-anual readings allow you to diagnose how the land is responding to methods being applied.
