Common Tree Snake (Dendrelaphis Punctulata)
The Common Tree Snake is a slender, diurnal colubrid species native to Australia and Papua New Guinea.
You’ll typically encounter this non-venomous reptile in tree habitats, where it exhibits excellent climbing abilities and swift movements.
To identify this snake, look for its distinctive olive-green to brown coloration, keeled scales, and an average length of 1-1.5 metres, though you may spot it in urban areas such as suburban backyards as it adapts well to human-modified environments.
Description & Appearance
Slenderness defines the Tree Snake. You’ll find this arboreal reptile with a long, thin midbody perfectly adapted for life among branches. The snake’s streamlined form allows it to move swiftly.
It exhibits remarkable colour variation. Its surface typically ranges from olive-green to bright blue, while its belly is often a vibrant yellow. This coloration provides excellent camouflage in its natural habitat. It has light blue skin between the scales, which may become visible when it eats a meal larger than its body.
Adults typically reach lengths of 1 to 1.5 metres, with females generally larger than males. The snake’s head is distinct from its neck, featuring large eyes with round pupils, indicative of its diurnal nature.
The species’ scientific name, Dendrelaphis punctulata, reflects its tree-dwelling lifestyle (Dendrelaphis meaning “tree snake”) and finely spotted appearance (punctulata referring to “dotted”).
Average Length
The common tree snake typically reaches an average length of 1 to 1.5 metres. However, some specimens have been recorded at lengths of up to 2 metres.
You’ll find that males and females exhibit similar size ranges. The snake’s elongated body allows it to navigate through branches and foliage with ease.
While the common tree snake isn’t venomous, its length can be intimidating. This evolutionary trait serves as a defence mechanism, deterring threats without the need for venom production.
Habits & Behaviour
This snake’s habits reflect its arboreal lifestyle and diurnal nature. You’ll find these slender reptiles actively foraging during daylight hours, mainly in trees and shrubs. Their excellent vision and agility enable them to navigate complex canopy structures with ease.
They rely on external heat sources to regulate their body temperature, often basking in sun beams and sunlit areas.
The Common Tree Snake exhibits the following behavioural patterns:
- Thermoregulation through basking and seeking shade
- Opportunistic feeding on small vertebrates, especially lizards and frogs
- Defence involving inflation of the neck and body
This species is oviparous, with females typically laying clutches of 3-6 eggs in concealed locations. They play an essential role in ecosystem balance as both predator and prey, contributing to the regulation of small vertebrate populations while serving as a food source for larger predators.
Identifying the Green Tree Snake
Identifying the Green Tree Snake can be achieved by observing the following characteristics:
- Slender body with elongated tail
- Keeled scales for enhanced climbing ability
- Large eyes with round pupils
- Colouration ranging from olive-green to bright blue-green
Habitat and Common Encounter Scenarios
Common Tree Snakes are frequently encountered in urban and suburban areas throughout their range in eastern and northern Australia.
You’re likely to spot these reptiles in gardens, parks, and bushland areas. They’re often seen basking on tree branches, fences, or rooftops during daylight hours. You may encounter these non-venomous colubrids while gardening or pruning trees. They’re known to enter houses, particularly in search of geckos or skinks.
Common Tree Snakes are excellent climbers and can be found at varying heights, from ground level to treetops.
During mating season (spring to early summer), you might observe two snakes intertwined in trees or on structures. If startled, they’ll quickly flee. In defensive displays, they may flatten their necks and inflate their bodies, but rarely bite.
You’re more likely to encounter juveniles in autumn, as they disperse from their hatching sites. During the colder months, they may enter homes in search of warmer climates.
If you spot one, maintain a respectful distance and allow it to continue its natural behaviours undisturbed.
Are Australian Tree Snakes Venomous?
Common Tree Snakes are non-venomous and pose minimal threat to humans, making them of low significance regarding danger. Their bites, while potentially causing mild discomfort, don’t require medical intervention.
Significance to Humans
Despite their intimidating appearance, common tree snakes pose minimal threat to humans. From a human perspective, common tree snakes offer several benefits:
- Pest control: They help reduce populations of potential household pests.
- Ecological indicators: Their presence signifies a healthy, balanced ecosystem.
- Scientific research: They provide valuable insights into reptilian behaviour and adaptation.
- Educational value: They serve as subjects for environmental education programs.
While encounters between humans and common tree snakes are relatively frequent due to their arboreal nature and proximity to urban areas, these interactions are generally harmless.
The species’ non-aggressive behaviour and lack of venom make them of little concern to human safety. However, their rapid movements and ability to climb may startle unsuspecting individuals.
Danger To Humans
Most common tree snakes pose minimal danger to humans due to their lack of venom. These snakes rely on agility rather than toxic secretions to subdue their prey. While they may bite if threatened, their teeth are small and typically cause only minor scratches or puncture wounds.
You shouldn’t fear these snakes as they’re non-venomous and generally non-aggressive. However, it’s essential to exercise caution when encountering any snake in the wild. These arboreal reptiles may become defensive if cornered or handled, potentially leading to a bite.
Although rare, such bites can cause mild discomfort, bleeding, and in some cases, allergic reactions. If bitten, clean the wound thoroughly and seek medical attention if you experience any unusual symptoms or if you’re unsure of the snake’s identity. Consequently, you should always maintain a safe distance and avoid direct contact.
Prevention and Avoidance Strategies
Common Tree Snakes are non-venomous, but it’s imperative to exercise caution. These reptiles are generally shy and prefer to avoid human contact. To minimise encounters and guarantee your safety, consider the following preventive measures:
- Maintain a tidy outdoor environment, removing debris and overgrown vegetation.
- Seal potential entry points in buildings, such as gaps around windows and doors.
- Install snake-proof fencing around your property, using fine mesh buried at least 15cm deep.
When hiking or exploring areas known for tree snake habitats, wear closed-toe shoes and long pants. Be vigilant when moving through dense foliage or climbing trees, as these are prime locations for these snakes. If you spot a tree snake, maintain a safe distance and allow it to retreat.
First Aid for Tree Snake Bites
When bitten by a tree snake, you’ll need to apply appropriate first aid measures immediately. Seek medical treatment promptly, as healthcare professionals can assess the severity of the bite and administer any necessary interventions.
While antivenom isn’t typically required for common tree snake bites, it may be necessary in cases involving other venomous species, emphasising the importance of accurate snake identification.
First Aid for Snake Bites
Despite their generally non-venomous nature, tree snake bites should still be treated with caution. While Common Tree Snakes aren’t considered dangerous to humans, it’s vital to follow proper first aid procedures for any snake bite, as misidentification can occur.
If you’re bitten by a snake you believe to be a Common Tree Snake, follow these steps:
- Remain calm and immobilise the affected limb.
- Apply a pressure immobilisation bandage to the bite site.
- Seek immediate medical attention, even if symptoms aren’t apparent.
- Don’t attempt to catch or kill the snake for identification.
It’s important to note that snake bite symptoms can vary widely among species. While tree snake bites typically result in minor effects, other Australian elapids can cause severe envenomation. Consequently, treating all snake bites as potentially life-threatening guarantees appropriate medical intervention, regardless of the species involved.
