Welcome at Steven Bol Gartersnakes

Caresheets and availabilty

On this website you can find information about the care in captivity of the different Species of gartersnakes (Thamnophis ssp.) and watersnakes (Nerodia ssp. and Natrix ssp.) I am breeding.

Under Availability you can check what offspring I currently have available.

Caresheets and terrarium

On this website you can find under Publications the different articles that have been published in the past years. The article about Thamnophis atratus atratus could serve as my general guideline (care-sheet) for most species of gartersnakes. For the Mexican species (Thamnophis eques, Thamnophis melanogaster and Thamnophis scalaris) my recent article about Thamnophis eques scotti is more relevant. In these articles you can find recommendations how to keep and breed these species in captivity.

“Certificate of origin”

Each snake is accompanied by a “certificate of origin” on which several facts are mentioned like: date of birth, correct name of the (sub) species, information about the family tree and the exact location on “County-level where they come from (when this information is available). This provides relevant back ground information on number of generations in captivity, to what degree the snakes are related, the natural habitat, the climate and hibernation. This can be taken in consideration in the way one takes care of the snakes: decoration of the terrarium, yearly fluctuations in temperature, duration of (and temperatures during) hibernation.

Observations in the wild

On this website you can also find observations done by the author in the wild (mostly North-America). Observing these fantastic snakes in their natural habitat adds an extra dimension to this hobby. I have been able to observe many of the species I breed in the wild. Interesting facts on the biology of these fascinating snakes (partly based on own observations) can be found under Publications, Species and News.

Genetic diversity

Inbreeding is prevented as much as possible by selective breeding programs using unrelated snakes of the same (sub)species, if possible originating from the same area. My offspring is hence very suitable to set up breeding programs. Information about origin and heritage are always provided by means of the “certificate of origin”.

Outdoor terrarium

Keeping gartersnakes and watersnakes outdoors is a very interesting and natural way to keep (at least some species of) gartersnakes and watersnakes. On this website you can find under News some observations done in my Outdoor terrarium.

Color morphs

For some species breeding programs for special color morphs have been set up.

  • I breed Melanistic (mostly black) Thamnophis sirtalis sirtalis and (very spectaculair!) Thamnophis melanogaster canescens.
  • Of the second species (Thamnophis melanogaster canescens) I am also breedings specimens which are very red (“high red”).
  • With Thamnophis elegans terrestris the focus is also on the “red morph”.
  • With Thamnophis sirtalis pickeringii I have set up a breeding program for the “blue morph”.
  • With Thamnophis ordinoides breeding programs have been set up with a “onestripe” morph beside the more regularly seen “3 stripe”morph, but this species is so highly variable that every individual snake has its unique pattern and coloration.
  • Thamnophis eques obscurus is usually bluish-grey in coloration, probably the entire population could be called axantic (missing yellow pigment) or hypoxantic (very low amounts of yellow pigment) but very recently albinos have been born.
    These are the first albino’s ever reported of the Mexican Garter Snake.
