Airports are designed to ensure the smooth and safe operation of flights; however, the presence of snakes in these environments can pose unique challenges and concerns. Understanding why snakes are present in the airport, recognizing the problems they can cause, and exploring effective solutions is crucial for maintaining a safe and secure airport environment.
Presence: Why Are Snakes Attracted to the Airport?
Attracted by Prey: The presence of grass can be found at almost every airport worldwide. Grass short or long can attract the presence of rodents, birds, and other small animals to the airport and can attract snakes looking for a meal. These snakes, being opportunistic hunters, follow their prey into airside areas, where the combination of open spaces and potential food sources creates an appealing habitat. In some instances, the presence of rodent burrows within these grassy areas not only serves as a food source for snakes but also becomes an appealing option for them to adopt as their own homes.
Heated Runways: Airports in warmer climates may inadvertently become attractive locations for these reptiles. Hot, sunny areas with hiding spots can appeal to snakes seeking warmth and shelter. Snakes are often attracted to the heat generated by airport runways and tarmacs due to their thermoregulation behaviour. As ectothermic creatures, snakes rely on external heat sources to regulate their body temperature. Airport runways, which are composed of materials like asphalt or concrete, absorb and retain heat from the sun. These warm surfaces become attractive basking spots for snakes, providing them with an opportunity to elevate their body temperature and enhance their physiological functions. The radiant heat emitted by the runways can be particularly inviting, especially in cooler periods or during dawn or dusk when the surrounding temperature is cooler.
Habitat Encroachment: As urbanization expands and natural habitats diminish, snakes are increasingly seeking alternative spaces for shelter and sustenance, inadvertently bringing them into airside areas. As previously mentioned, airports are grassy open landscapes, this can inadvertently become attractive habitats for snakes seeking shelter and food sources. The phenomenon of snake habitat encroachment into airports has become a growing concern in recent years especially in newly-constructed airports. Factors such as the availability of prey and hot airport runways further contribute to this encroachment.
Problems: What Challenges Are Caused by Snakes in the Airport?
Safety Concerns: Snakes can pose a direct threat to airport staff, ground crew, and passengers. While the majority of snakes are non-venomous and generally shy, encounters with venomous species can result in serious health risks from potential bites or injuries. Venomous snake bites can cause symptoms ranging from mild discomfort to life-threatening reactions, necessitating immediate medical attention. Certain snake species, such as spitting cobras, can expel venom with impressive accuracy. This venom is aimed at the eyes of the potential threat, human, and can cause severe irritation, pain, and even temporary blindness.
Strikes: Snake strikes at airports, though relatively uncommon compared to bird strikes, can pose unique challenges and safety concerns. These incidents typically involve a snake meeting an aircraft during take-off or landing. The consequences of a snake strike can vary depending on the size and location of the snake, as well as the speed and altitude of the aircraft. While smaller snakes may not cause significant damage, larger species like pythons could lead to mechanical issues or damage the aircraft's exterior.
Operational Disruptions: The sighting of snakes on or near runways can prompt temporary closures and delays, disrupting the meticulously orchestrated schedules of flight operations. Such interruptions can lead to flight cancellations, missed connections, and logistical challenges for airlines and airport authorities. The economic impact can be notable, with airlines facing financial losses and airports grappling with decreased efficiency and potential reputational damage.
Solutions: What Can Be Done About Snakes in the Airport?
Habitat Modification: Modifying the airside environment to make it less attractive to snakes is one of the most sustainable ways to deter them from entering airport areas. This may involve minimizing vegetation, removing debris, and implementing landscaping practices that discourage snake habitation. One approach is filling in rodent burrows or employing rodenticides to diminish the population of rodents in the airside, a common attractant for snakes. Another strategy involves the installation of barriers, such as snake-proof fencing, to impede easy access to crucial operational zones. By minimizing hiding spots and limiting potential prey sources, airports aim to discourage snakes from establishing habitats within their premises.
Training Programs: Educating airport staff on identifying snake species, distinguishing venomous species, understanding appropriate responses, and emphasizing the importance of reporting sightings can be beneficial for both airport safety and the well-being of the snakes. Snake awareness and education programs play a pivotal role in enhancing safety and fostering coexistence between airport operations and the local snake population. These initiatives are designed to educate anyone from airport personnel to ground crews and other stakeholders. By raising awareness, airports empower their staff to take preventive measures and respond effectively to potential encounters, reducing the risk of snake-related incidents.
Professional Removal Services: Snake professional removal services are essential when dealing with the presence of snakes in airside areas. These specialized services involve the deployment of trained professionals with expertise in identifying, capturing, and relocating snakes safely. Upon receiving reports of snake sightings, these professionals assess the situation, determine the species involved, and employ appropriate techniques for removal. The goal is not only to eliminate immediate safety concerns but also to ensure the well-being of the snakes by relocating them to more suitable habitats.
Wildlife Hazard Management Programme: A Wildlife Hazard Management Programme (WHMP) in an airport is a crucial framework designed to mitigate potential risks associated with wildlife, including snakes, and ensure the safety of aviation operations. Within the WHMP, specific strategies and protocols are implemented to address the presence of snakes on airside areas. This program typically involves regular wildlife surveys, monitoring of snake habitats, and the development of preventive measures to minimize the likelihood of snake encounters. Every aspect mentioned earlier, encompassing habitat modification, training programs, and professional removal services, would be comprehensively outlined within the WHMP.
Snakes on the airside present unique challenges that require a proactive and multifaceted approach. By understanding the reasons behind their presence, recognizing potential problems, and implementing effective solutions will benefit both airports and snakes alike.
