Since only saiga males are hunted for their long, wax-colored horn (females are also hunted, but their lack of horns limits their trade value), mass hunting affects reproduction as it skews the sex ratio. The most frequently cited benefits of beaver dams were increased habitat heterogeneity, rearing and overwintering habitat; flow refuge; and invertebrate production. They're famous for their massive migrations through open tundra habitat, but some herds and subspecies also make their home in boreal forests.
