A garter snake can complete maturity at one to two years of age.As soon as garter snakes emerge from hibernation in the spring, these snakes begin mating. The males first leave the den, while waiting for female garter snakes to release their pheromones by encircling the female garter snake. These pheromones are released to attract the female for mating. After the female garter snakes have been selected and mated with the selected male garter snake, the female garter snake returns to her summer habitats to eat and find a suitable birth site.A female garter snake gives birth to almost five to 70 young garter snakes in the form of eggs. The eggs, now young ones, may need to find food for themselves, as these reptiles are independent since birth. Garter snakes are born with a total length of roughly 6-8 in (15-20 cm). These snakes tend to grow really quickly. At a week, a young garter snake can be up to 7 in (17.5 cm) in total length. In a month, a young garter snake can grow up to 12 in (30 cm) in total length. In a year, a garter snake can grow up to 18 in (45 cm) in length. Garter snakes grow and mature in two years. The total length of a garter snake can be up to 30 in (76 cm).

Regardless of the fact that common garter snakes are harmless snakes a bite of the garter snake is not dangerous to humans, that may produce minor irritation, burning, and swelling, although humans frequently attack them.The usage of pesticides has resulted in a large reduction in the population of common garter snakes in several locations. The number of garter snakes in the wild has also decreased due to loss of habitats and over-collection for the commercial pet trade. Because so much of this species’ food is aquatic, water contamination has become an issue. Since common garter snakes perform hibernation in larger groups and reproduce fewer young common garter snakes each year, northern populations of garter snakes are much more endangered than southern populations.The decline in common species is important to study, as it is very important to conserve and protect these species. The decline of common garter snakes is important to study, as it can inform us a lot about our natural ecosystem.Did you know that the subspecies of common garter snake that is known as San Francisco garter snake Thamnophis sirtalis tetrataenia has been considered Endangered since the 1960’s in the US and California?Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
