Females can produce 2 to 5 litters of about 2 to 7 offspring with a three-week interval in between each litter which is why this group of lagomorphs are known to have the fastest growth rates of their order. Location of Repository GIS analysis of the spatial relationship between plateau pika burrow dis-tribution and vegetation distributional patterns . For plateaus formed by extrusion, the rock is built up from lava spreading outward from cracks and weak areas in the crust.
