The Richardson's Ground Squirrel is sexually mature at approximately one year of age. The female usually bears her young between the months of April and May, in the safety of her burrow or nest. After six to eight weeks, the pups are ready to some out and begin to learn foraging techniques from the adults. In the wild, once a young squirrel leaves the nest, the chance of the pup surviving to the next year is one in four. The average lifespan of the Richardson's Ground Squirrel is three to four years. No information about captive breeding has been found.
