What is Herpetology?

Herpetology is a discipline within Biology that involves the study of Amphibians (caecilians, frogs, toads, salamanders) and Reptiles (amphisbaenians, lizards, snakes, turtles, tuatara, crocodilians). These studies range from molecular to community level investigations of the evolutionary relationships, physiology, ecology, and conservation of these fascinating animals. Although amphibians and reptiles are not closely related from an evolutionary perspective, they are often studied together because they live in similar habitats and share certain traits that make them susceptible to the same threats. For example, all amphibians and reptiles are ectothermic, meaning that they rely on the external environment to regulate their bodily functions, such as body temperature. Thus, the behaviour and habitat use of both reptiles and amphibians are largely governed by environmental conditions. Many species of amphibians and reptiles are at risk of extinction, largely as a result of human-caused threats, such as habitat destruction, road mortality, environmental contamination, the spread of invasive species and illegal poaching. Thus, research into many aspect of the biology and ecology of our native herpetofauna is critical in informing effective conservation and management solutions.

 Canadian Herpetological Society (CHS).
The mandate of CHS is to foster research and conservation of Canada's reptiles and amphibians, collectively known as herpetofauna. This website provides information about Canada's herpetofauna, as well as resources to assist researchers and conservation professionals within Canada.
We are still developing the content for some of our pages. Links to pages that are not yet available will be marked as "coming soon". We hope to have all of the content on our site complete by early 2016.


What is the Canadian Herpetological Society?

The Canadian Herpetological Society is a registered Canadian charity that advances reptile and amphibian research and conservation in Canada by:
  • promoting scientific research on reptiles and amphibians and disseminating the results;
  • facilitating collaboration among amateur and professional herpetologists;
  • advancing public understanding of our native reptile and amphibian species, the threats they face and the conservation solutions that exist; and
  • promoting, supporting and leading conservation and stewardship projects.
CHS is made up of researchers, conservation practitioners, naturalists, educators, and other individuals with an interest in Canada's reptiles and amphibians.
The Society holds an annual general meeting and conference where members can present their work, learn what others are doing, and identify opportunities for partnerships and collaborations.
The Canadian Herpetologist is a bi-annual publication of the CHS that is available to all members. Back issues are posted on the web-site and are available to non-members.

Mission

The Canadian Herpetological Society is devoted to fostering scientific research on amphibians and reptiles and, in recognition of the inherent value of all native amphibians and reptiles, conserving Canada’s native species of amphibians and reptiles and their ecological and evolutionary functions in perpetuity.


Governing Documents

Our History

The Canadian Herpetological Society was formed when the Canadian Amphibian and Reptile Conservation Network (CARCNET) and the Canadian Association of Herpetologists (CAH) decided to come together to form one society in the fall of 2013.
The Canadian Association of Herpetologists was formed in 1986 as a venue to disseminate news and information of relevance to Canadian Herpetologists. Membership of this organization was primarily professional academic herpetologists with interests such as morphology, systematic, ecology and behavior. The Canadian Amphibian and Reptile Conservation Network grew from the Declining Amphibians Populations Task Force in Canada (DAPCAN) which began in 1991. After some time, those involved in DAPCAN decided that they wanted to focus on amphibians and reptiles, as well as active conservation of these species rather than simply documenting declines. The Canadian Amphibian and Reptile Conservation Network was born as a more proactive group, and became a registered charity (Charitable Reg. No. 88078-1562-RR0001) in 1997.
Recently, CAH and CARCNET began co-hosting annual meetings and also merged their two bulletins into a joint bi-annual publication, The Canadian Herpetologist. Following from this close collaboration and a significant overlap in general membership and the Boards of Directors, the time came to formally merge into one organization. Although CAH was focused more on academic research and CARCNET on conservation, there is inherent overlap between these mandates and it is difficult to have one without the other. For example, although CARCNET's primary mandate was conservation, there has always been a significant focus on applied research that can inform conservation work, as well as disseminating research findings amongst the membership. In recognition of this, the new Canadian Herpetological Society includes both research and conservation in its mandate.

Taking the best possible care of Your Savannah Monitor

One of the biggest misconceptions about Savannah Monitors is that they are desert dwelling animals; >This is false information Watch Video - Savanna Biome
Virtually all of the Savannah Monitors captured for the worldwide pet trade are "harvested" from Ghana Africa, a coastal grassland, that has rich grassy vegetation and relatively high humidity for much of the year. When we fail to provide the required humidity in captivity, these majestic animals perish from various states of dehydration. What many keepers fail to realize is that these animals spend much of their time down inside Burrows (or tunnels) under the ground to conserve moisture and avoid predators. These burrows are very important to the overall health of your lizard.
Savannah Monitors are very intelligent animals, they require stimulation, locked inside four walls with nothing to do is comparable to solitary confinement in prison, They NEED space, they NEED dirt to dig burrows in. Like a child in a sandbox, nothing else you can do for your animal is better than to give it plenty of sandy soil mix to tunnel in and providing enrichment to keep the animal's
mind keen. Monitors in captivity can become bored. (wouldn't you be in a box?)
If you wish to keep your Savannah Monitor healthy and alive for more than a year or two, you simply must provide a large sealed enclosure with a solid 24 inches of soil that will hold a burrow without collapsing on the animal while it spends most of it's time in there. The preferred substrate of many advanced keepers is a mixture of soil and sand. (See Bio Active soil page)

Temperatures and Humidity

To properly support your Savannah Monitor, a wide range of options is usually deemed the best way to raise a healthy animal, Quite honestly you simply cannot provide this with any size "fish tank"! Click here to see why this is the single most important factor of proper care.
The humidity inside your enclosure should range from very low (directly under the basking lamps) to very high (nearly 100% down in the burrows and about 60% overall humidity on the cooler end of the cage.
A high quality digital hygrometer is mandatory for monitoring the environment inside your enclosure. Guessing the humidity will not work.
A high quality digital thermometer or temp gun is also a necessary tool required to properly set up and maintain your monitor and keep it healthy.
Failure to provide sufficient basking temperatures and correct humidity, as well as supported burrowing, is stressful the lizards internal organs and leads to dehydration and gout.
It has been concluded that chronic exposure to insufficient basking temeratures prohibits proper renal tubule function leading to kidney damage and failure over time. Source: Robert W. Mendyk, Zoo Biology 00: 1-11 (2012)
As a general rule of thumb, basking spots should be a minimum of 130 - 150 degrees Fahrenheit.
Recently I documented my lizards baskig at almost 180 degrees. View Photo (click).
Allowing your captive Monitor Lizard to roam about the house or keeping it in a room is not a suitable substitute for a proper enclosure.

Lighting your enclosure.

For optimal basking, without risk of burns, it is common practice to use a cluster of three smaller 45 to 50 watt halogen flood lights rather than one big light. Experienced keepers use common floodlight bulbs sold at most retailers / hardware stores for use in outdoor security lights. They cost a lot less than reptile bulbs sold at pet shops, and work just as well.
Optimal basking temperatures should be right around 130-155 degrees (F) and be broad enough to cover most of the lizards body while sprawled out under the lamps. Warning! the use of a single high wattage lamp will burn your lizard and dry out the air in your cage.
It is also of no harm and thought to benefit the lizard if there is at least one UVB lamp in use to enhance the simulation of sunlight.

Food options

Savannah Monitors are primarily insectivores in the wild, there is however, some controversy about feeding rodents in captivity. This is a long winded and foolish argument.
A properly supported Monitor can handle mice and rats in their diet without any problems. However, the vast majority of keepers do not provide the correct housing for their captive lizards and the resulting health issues are often blamed on the rodent diet, when in fact improper husbandry that brought on the failure in the animal's health. Be sure to read the dehydration and gout page carefully, or your lizard will not live to be very old.
A proper Savannah Monitor diet would consist of Roaches, Crickets, Night Crawlers (Large earth worms) Mice, Rats, Snails, Garden slugs, Superworms and Locusts (where available) and certified chemical free organic whole Shrimp, Crabs, Crayfish & Chicks.

Poor foods

Some of the worst things people could ever feed their captive Savannah Monitors...
    Dog food, Cat food, Canned anything! Why? Read this link
  1. Chicken parts, ground Turkey, animal parts.(Lacking essential minerals)
  2. Boiled or scrambled eggs & cooked foods.(Cooking destroys nutrients)
The above items are not nutritionally complete, canned goods are almost all treated with chemicals, therefore the above items should be avoided.
Failure to provide these basic requirements will result in your animal languishing and ultimately perishing from dehydration related complications or other health issues and dying a gruesome death.

Summary of a Properly supported Savannah Monitor

  1. Minimum cage size 8 feet x 4 feet x 4 feet or bigger
  2. Deep sandy soil floor to support digging burrows
  3. Hot basking area of 130 degrees (F) or HOTTER
  4. 60% average humidity or higher
  5. large water dish (Changed daily or more)
  6. several hiding areas located throughout the cage.
  7. 6500K and supplimental UV lighting, it should be well lighted during the daytime cycle to simulate a sunny afternoon in Africa.

The annual Savannah Monitor tragedy

LittlefootEvery year, beginning in March, the reptile market becomes flooded with baby Savannah Monitors. Thousands are imported from Africa and sold over the internet, at pet shops and reptile shows for as little as $15 per lizard.
The irresponsible sellers of these baby animals are nearly all guilty of holding back the necessary information required to properly take care of these lizards. Because of this, almost every one of these babies fail to reach their first birthday.
After all, if the seller were to inform the buyers that the "cheap" lizard they were about to purchase was going to need a cage the size of a room with (literally) a ton of dirt in the bottom, it was going to eat several thousand dollars worth of food and may never become "dog tame" they would not sell very many of them. In our struggling economy; that is not going to be a popular move, so they often (nearly always) distort the truth and will tell you whatever you want to hear, just so they can collect your money. This is heartbreaking and tragic.
