Grids placed over the photographs could simplify percent cover estimates. Wind patterns must be considered with such data recording techniques. There are obvious difficulties in establishing transect lines against prevailing winds or photographing in high wind areas. Photgraphic records of permanet experimental sites, or photo points, can be a simple, rapid, and cost effective laternative to aerial photos. The belt transects are divided into blocks to allow for a precise estimate of community composition.
Plant counts within the photographed area supplement transect data.
In areas of low shrub density, the photographs can provide sufficient assessment of change and additional transect data is not needed. Quadrats established in regular intervals between transects are used to assess soil surface condition. Summary Quantitative information on the structure of a plant community is desirable for planning, and evaluating the success of restoration and revengetation projects. Traditional plant sampling methods such as quadra sampling, plot-less methods, and distance methods can provide accurate estimates of cover, density, and frequency. However, the extensive labor and preparation needed may make these techniques poorly suited for characterizing large mitigation sites.
