Sketch showing the U-shaped vertical net setting. e) The set-up should be located downwind (considering dominant wind.) A strong wind has always proven advantageous. Characteristics of the herds Because most caribou get entangled in the nets by their antlers (Figure 8), it is important that the herd selected for capture be made up predominantly of antlered animals. In March and April, most adult stages have shed their antlers and are found in segregated, "bachelor", herds. The herds of predominantly antlered animals are made up of adult does, and young stags. Such herds are easily caught and ideally suited to provide stock for introduction pur- poses. Large lakes with many herds of caribou in their vicinity are preferred, because several capture attempts can be made without moving the installations. Often the same herd can be driven more than once toward the same set- ting. Description of the nets and of their installation Several types of netting were used, either singly or in combination; a) cotton or nylon "salmon nets", 10 feet high by 100 feet long, with 4-inch mesh, and b) cotton "seal nets" (twine Vh"), 20 feet high by 100 feet long, with 10-inch mesh. Between 300 and 400 feet of netting were used in a single installation. The nets were set in a U-shaped fashion, hooked upright on broken tree tops or branch stubs within the forest, some 50 to 100 feet from the shore (Figures 3 and 7). The bottom of the net was spread either inward or outward on the surface of the snow. On certain occasions leg and/or body snares were placed in front of the nets. Leg snares were laid flat on the surface of the snow, with a noose diameter of 18-24 inches. Body snares were set 18 inches from the ground across trails. The diameter of the noose varied from 36-48 inches. Both types of snares (V2 inch hempen or tergal ropes)
