Nature at the airport edge: ticks, wildlife and plants at the spotter hill

Three hours at the hill, the wind has turned, the evening landings came as if ordered – and in the shower you discover a small black dot in the crook of your knee. Spotting happens outdoors, and around airports outdoors often means meadow, field edge, bushes and unmowed fence strips. Ticks, wildlife and plants at the spotter hill are no reason to stay home. If you know where the risks lie, though, you can keep them under control with surprisingly little effort. This guide shows you what can realistically happen at the airport edge, how to protect yourself and how to deal with animals at the fence.

Nature at the airport edge: the short answer

The main risks at the spotter hill are ticks in tall grass, irritating or phototoxic plants at path edges and – less often – insects and caterpillar hairs at forest edges. Wildlife itself is hardly dangerous to you; what is more problematic is what people do with it, such as feeding it at the fence. The countermeasures are unspectacular: long pants, closed shoes, a look at the ground before you set up the ladder, and a thorough tick check after every session.

Why airports in particular? Around runways there are large grass areas, noise barrier berms, dirt tracks and compensation areas. Many spotter hills are piled-up, grassed earth mounds, often with bushes on the flanks. At the fence itself, a strip often remains that is mowed less often. That is exactly the mix in which ticks lurk and pioneer plants grow.

Ticks: the most common risk at the hill

The tick most likely to get you in central Europe is the castor bean tick (Gemeiner Holzbock). It does not fall from trees but waits in tall grass, undergrowth, bushes and leaf litter until a host brushes past. At the spotter hill, that means: the mowed lawn on the top is comparatively harmless, while the beaten path through knee-high grass to the best photo position at the fence is not.

Ticks are already active from about 5 degrees. In mild years the season therefore starts early in spring and reaches far into fall. Anyone sitting on the hill in sunshine in October is not automatically in the clear.

Which diseases ticks transmit

Two diseases are relevant for spotters in Germany, Austria and Switzerland:

Criterion	TBE (FSME)	Lyme disease
Pathogen	virus	bacteria (Borrelia)
Distribution	regional, mainly in risk areas	throughout Germany, regionally up to a third of ticks are infected
Transmission	possible early during feeding	risk rises significantly with longer feeding time, especially after more than twelve hours
Vaccination	yes, primary immunization with three doses	not available in Europe
Typical warning sign	flu-like symptoms, rarely later meningitis or encephalitis	bull’s-eye rash, fever, headache and muscle pain

TBE risk areas in Germany are designated anew by the Robert Koch Institute every spring. The main focus is in Bavaria, Baden-Württemberg, southern Hesse, southeastern Thuringia, Saxony and southeastern Brandenburg, plus individual districts in other states. In Austria the entire country counts as a risk area, in Switzerland the whole country except Ticino. So if you regularly stand at the Munich Airport visitors’ hill (Besucherhügel), the Vienna Airport spotter hill (Spotterhügel) or the Butzenbüel in Zurich, you are moving in a region for which health authorities recommend vaccination in case of tick contact. Whether it makes sense for you is something to clarify at your family doctor’s office.

Lyme disease, on the other hand, is not a regional topic: the pathogens occur nationwide. The good news: only a small share of tick bites actually leads to illness, and anyone who removes the tick in the first hours lowers the risk considerably.

How to protect yourself on the fence path

• Long pants, pant legs tucked into your socks. Not elegant, but it keeps ticks from crawling straight onto your skin. Closed shoes instead of sandals.
• Light-colored clothing. On light fabric you see the dark animals before they have found a spot on your skin.
• Repellent on skin and clothing. Tick repellents help but work only for a limited time and not completely. Reapply after a few hours at the hill.
• Avoid the edge strip where you can. Use existing paths and mowed areas. If you put the ladder in the middle of tall grass, you stand in a tick hotspot for minutes. What else to watch out for when setting up is in the article Ladders, steps and tripods at the airport fence.
• Do not put backpacks and camera bags in the grass. A mat or a spot on the ladder step is better. Gear tips are in the guide to the camera backpack for plane spotting.

The tick check after the session

The most important protection comes after spotting: check your whole body. Ticks prefer warm, thin areas of skin – scalp and hairline, behind the ears, neck, armpits, elbow creases, belly button, groin and the backs of the knees. With children, it is especially worth looking at head and neck; more on outings with kids is in the article Plane spotting with kids.

If you find a tick, you grasp it with fine tweezers or a tick card close to the skin and pull it slowly and straight out. Do not squeeze, no oil, no glue, no cream – that stresses the tick and can release more pathogens. Then disinfect the spot. A photo with the date on your phone helps if a redness appears in the next few weeks.

Plants you should know at the airport edge

Airport edges are classic “disturbed areas”: construction sites, piled-up berms, road embankments, fallow land. Exactly there, pioneer plants settle – including some you had better not touch.

Giant hogweed

Giant hogweed is hard to miss: it often grows up to three meters tall, has a thick, usually reddish-spotted stem, huge divided leaves and white umbel flowers often 30 to 50 centimeters across. It blooms around June and July and likes to grow at path edges, fallow land, spoil heaps and stream banks.

The plant sap is the danger: it contains substances that make skin extremely sensitive to sunlight. The result can be redness, blisters and burn-like wounds that appear with a delay – after hours or even days – and can leave visible pigment spots for a long time. For spotters fighting their way through scrub to the fence on sunny days, that is a real trap. On contact: avoid sun, wash the skin thoroughly with water and soap, and seek medical advice if there are reactions. Be careful with identification: it can be confused with the native common hogweed, which stays much smaller, and with angelica species.

Ragweed

Common ragweed, usually just called ambrosia, is less conspicuous: a bushy, heavily branched plant with finely divided leaves whose underside is green. It prefers to grow on road and path edges, construction sites, railway embankments and fallow land. Its pollen is considered a strong allergy trigger, and because it blooms from about July to October, it considerably extends the pollen season for allergy sufferers. If your eyes suddenly water at the fence in late summer even though the grasses are long done, think of it. In Switzerland, ragweed is subject to a reporting and control obligation.

Oak processionary moth caterpillars

Not a plant, but a plant-related topic: the caterpillars of the oak processionary moth live on oaks – at forest edges, on single trees along roads and preferably in warm, sunny spots. From a certain larval stage, usually in May and June, they develop stinging hairs that break off easily and are blown away by the wind. Contact can cause itchy skin rashes, eye irritation and breathing problems. Tricky: the hairs stay active for a long time and accumulate over years in old nests and in the undergrowth. If oaks along a path are cordoned off or marked with warning signs, take the warning seriously and find another position.

Plant / animal	Where at the airport edge	Critical time	What happens	What you do
Giant hogweed	path edges, fallow land, ditches	summer, especially in sun	phototoxic skin damage	do not touch, wash on contact and avoid sun
Ragweed	embankments, construction sites, roadsides	July to October	severe pollen allergy	allergy sufferers avoid stands, carry medication
Oak processionary moth	oaks at forest edge and road	May to summer, hairs long afterward	skin, eye and airway irritation	keep your distance, respect barriers, do not sit under infested trees
Nettles and thorns	fence base, bushes	year-round	stinging, scratches	long pants, gloves when setting up the ladder

Insects: wasps, bees and mosquitoes

On warm days there is a lot going on at the hill, and not only in the air above the runway. Wasps are interested in sweet drinks and snacks, bees in flowering meadows. For most people a sting is unpleasant but harmless. It looks different with an insect venom allergy: if you know you have one, you always carry the emergency kit prescribed by your doctor – even on the “just a quick trip to the hill.” Drinks in closed bottles instead of open cans prevent the classic of drinking a wasp.

At wet meadows and ditches, mosquitoes join in the evening. The same repellent you use against ticks usually helps here. How to additionally protect yourself against heat and UV on long summer sessions is in the guide Plane spotting in summer.

Wildlife at the airport: watch, do not intervene

Anyone who stands at the fence often sees more than aircraft. On the large grass areas between the runways, depending on the airport, hares, rabbits, foxes, deer or birds of prey show up. For many spotters this is a welcome side subject – a kestrel in front of a taxiing long-haul jet is a picture you do not get every day.

It is important to understand why these animals live there the way they do. Airports run deliberate habitat management: the grounds are designed so that large birds and flocks find little food and hardly any nesting opportunities there, because they can become dangerous for aircraft taking off and landing. If that is not enough – for example after snowfall or right after mowing – birds are scared off, in Germany usually with bangers. If you suddenly hear a bang at the fence, it is therefore no cause for concern but part of operations. At large airports, birds of prey or sound deterrents are sometimes used too. The background is explained in the article Bird strikes.

Clear rules follow for you:

If you find an injured or dead animal, do not touch it. If it is outside the airport grounds, in Germany the police are a good contact; they can reach the responsible hunting tenant (Jagdpächter). If it is on the grounds, inform the airport or the security service. You never climb over the fence – more in the article Proper behavior at the airport fence.

Respecting nature: paths, fields, protected areas

Many airports are surrounded by fields, meadows and compensation areas. Some of them are farmed, others designated as ecological compensation areas. Whether you may enter an area depends on state law and on its use – a field with standing crops is something different from a public dirt track. The basics are explained in the guide Right of access to open countryside.

In practice at the airport, that means:

• Stay on paths. Beaten paths straight across meadows destroy vegetation and disturb ground-nesting birds. They also lead straight through the tick zone.
• Leave no traces. Take your trash, cigarette butts and packaging with you. Food scraps attract crows, gulls and foxes – exactly what the airport wants to avoid.
• Heed signs. Nature reserves and closed areas at the airport edge have their reasons. Anyone who wants to use drones must follow especially strict rules in such areas; details in the article Drones over residential areas and nature reserves.
• Quiet and unobtrusive. Consideration for animals is also consideration for residents and other spotters – more in the spotter etiquette.

Common mistakes at the spotter hill

• Shorts in tall grass. The classic in high summer – and the direct route to a tick bite on the lower leg.
• Forgetting the tick check. After a long session you are tired. Precisely then a tick stays unnoticed overnight, and the Lyme disease risk rises with every hour.
• Using a giant plant as a screen. Anyone who hides behind a big umbel bush to photograph better can get a painful sunburn of a special kind from giant hogweed.
• Leaving snacks at the fence. Attracts wasps and lures animals to the fence – you want neither.
• Chasing animals. A fox in the meadow is no reason to enter the field or squeeze along the fence.

If you are going through your gear anyway, the gear checklist complements the nature topics with camera, batteries and weather protection.

Conclusion

Nature at the airport edge is a part of the hobby many underestimate – for better and for worse. Ticks are the most common risk but can be well controlled with long clothing, repellent and a consistent check after the session. In TBE risk areas, which include large parts of southern Germany, all of Austria and almost all of Switzerland, a conversation about vaccination is worthwhile. Giant hogweed, ragweed and caterpillar hairs you can recognize from afar with a bit of practice. And wildlife at the fence is a nice extra as long as you observe rather than feed it.
