How Do Contour Line Densities Indicate Animal Concentrations?

Understanding Contour Line Densities

Topographic maps use contour lines to represent elevation changes on the landscape. Contour line densities indicate the steepness of slopes and the presence of features like ridges, valleys, and benches. By studying contour line densities, hunters can identify areas with specific habitat features that attract and hold wildlife populations.

Identifying Animal Concentrations

A density of 1-2 contour lines per mile typically indicates gentle slopes and open terrain, while a density of 2-5 lines per mile suggests steeper slopes and more rugged terrain. Areas with a density of 5-10 lines per mile often feature narrow ridges, rocky outcroppings, or other terrain features that support a higher concentration of wildlife. By interpreting contour line densities in this way, hunters can narrow their search for animal concentrations and increase their chances of success.

Applying Contour Line Densities to Hunting Strategy

When planning a hunt, consider the following techniques: Look for areas with a high concentration of contour lines (e.g., 5-10 lines per mile) and a corresponding change in vegetation or land use. Identify the location of water sources, such as streams, rivers, or springs, which often attract wildlife. Use a combination of contour line densities and other map features to identify potential locations for animal concentrations and develop a targeted hunting strategy.
