Taking photographs is one of the most basic monitoring techniques. While
photographs cannot tell the entire story about a situation, project, or
practice, much information can be gathered from photographs taken at the
same point over a number of years.
Photographs often reveal changes that measurements miss. Photos are an
easy way to help others become aware of differences induced by climate
and the benefits of good land management practices. They serve as a reminder
of how far you have come in establishing a healthy-functioning, natural
resource area.
There are many monitoring techniques available, but if you consider these
following questions when selecting a monitoring approach, photo points
fit most ranch needs.
However, before you start taking pictures, think of why, what, and how you might set up a photo monitoring program.
The following table suggests photo situations for documenting effectiveness of various management practices on rangelands.

Enhances Watersheds (water, quality, & quantity) by... |
Monitor by Taking (before, during, after) Photos of... |
| Brush control in uplands | ...reducing transpiration, allowing grasses to increase so they can impede and filter overland flow, and increase their root density to hold soil | ...sites where brush has been killed or removed |
| Manage grazing of domestic livestock through new rotation patterns, fences, or water developments | ...increasing grass cover and vigor in uplands to intercept rainfall, impede and filter overland flow, and reduce erosion and siltation. Reducing compaction in riparian areas so as to reduce bank failures, erosion, and stream siltation | ...representative areas in uplands and of streambank profiles in riparian areas |
| Install gradient stabilizing drop structures to partially block stream flow and form pool | ...reducing stream velocity, trapping sediment, reducing streambank erosion and channel cutting, and promoting streambank revegetation | ...profiles of representative streambanks. Measure the depth of silt behind the structures |
| Herbaceous plantings in uplands | ...increasing grass cover to intercept precipitation, impede runoff, reduce erosion, increase infiltration, and filter overland flow | ...representative landscapes |
| Planting vegetation in riparian areas | ...anchoring riparian soil, reducing streambank failure, erosion, and channel cutting; promoting revegetation of streambanks and restoring channel profile; trapping debris, filtering the stream, providing shade, and reducing stream temperature | ...representative streambank profiles (with the horizon at the edge of the photo) |
| Install riprap to form barriers along streambanks | ...impeding stream flow and velocity along the banks; reducing erosion, channel cutting, and bank failure; reducing siltation, promoting revegetation of streambanks to further trap sediment; reducing compaction and trampling by livestock in riparian areas | ...cross-sections of streambanks, focusing on locations of typical installations |
| Install head-cut control devices | ...stopping channel cutting, promoting channel healing, helping restore channel profile, and promoting water storage in riparian areas | ...treatment areas, providing an oblique view of problem sites |
