What tips are there for interpreting Google Earth imagery for wildlife?

Analyzing Terrain Features

When using Google Earth for wildlife scouting, it’s essential to understand the terrain and how it affects wildlife movement. Look for ridges, valleys, and gullies that can act as funnels or barriers to movement. A funnel is a narrow passage of land that allows animals to move through a specific area, often leading to a bedding area or other habitat feature. For example, a stream valley may funnel deer movement to a specific point, making it a prime location for hunting. Use the ruler tool to measure the distance between terrain features and estimate the time it would take for animals to move between them.

Identifying Bedding Areas

Bedding areas are critical locations where wildlife rests, hides, and feels secure. On Google Earth, look for areas with dense vegetation, such as thickets or thick grass, which provide cover and concealment. These areas often have a distinct shape, such as a circular or oval pattern, and may be surrounded by a clear edge or boundary. Use the historical imagery tool to analyze changes in vegetation patterns over time, which can indicate long-term bedding areas. For example, a circular patch of dense vegetation may remain unchanged for several years, suggesting a consistent bedding area.

Using Historical Imagery

Historical imagery is a powerful tool for understanding long-term changes in wildlife habitats and identifying patterns of movement. By analyzing imagery from different years, you can detect changes in vegetation, water sources, and terrain features that may indicate shifts in wildlife populations or behavior. Use the slider tool to compare imagery from different years and look for changes that may be indicative of wildlife activity. For example, a change in the location of a deer bedding area may indicate a shift in population or habitat use.
