Quick Answer
Dense thickets of shrubs and small trees, often consisting of dogwood, cedar, or willow, can indicate a good terrain funnel for whitetail hunting. These areas typically funnel deer movement into narrow corridors, increasing the chances of encounters. Look for vegetation with a mix of dense undergrowth and tall canopy.
Identifying Terrain Funnels
When identifying terrain funnels, look for areas where dense vegetation funnels deer movement into narrow corridors. These corridors can be created by a combination of topography and vegetation, such as hillsides, ravines, and creek bottoms. A good rule of thumb is to look for areas where deer can easily move from one side of a valley or ridge to the other. In these areas, dense thickets of shrubs and small trees often dictate the path deer will take.
Measuring Terrain Funnels
To accurately measure the effectiveness of a terrain funnel, use a technique called a “funnel ratio.” This involves measuring the width of the funnel at its widest point and again at a point 100 yards down the corridor. A funnel ratio of 3:1 or greater indicates a high-probability area for deer movement. For example, if the funnel is 50 yards wide at its widest point, it should narrow to 16.7 yards (50 / 3) 100 yards down the corridor.
Hunting Terrain Funnels
When hunting terrain funnels, focus on areas where the funnel narrows and the deer are funneled into a smaller space. This can be a treestand or ground blind location, typically within 20-30 yards of the funnel’s narrowest point. Be prepared for rapid movement and short shooting distances, as deer often move quickly through these areas. Use camouflage and scent control to remain undetected, and consider using a tree stand or ladder stand to get above the deer’s line of sight.
