Wildlife calendar year at Gatwick

A selection of wildlife commonly found on the biodiversity sites, landside at Gatwick Airport.

January

Roe Deer - Capreolus capreolus

Our largest mammal species on site. I've also seen Fallow Deer very closeby, but never actually within our site boundaries.

February

This isn't a fungus, but is actually a type of bacteria called Nostoc commune; a colonial species of cyanobacteria.

Cyanobacteria are thought to have converted Earth's early atmosphere into an oxygen-rich one. It occurs extensively on the bare clay soil around the North West Zone and from a distance resembles squished rabbit poops.

March

Common Toad - Bufo bufo

We often find Toads under the reptile matts long before the Grass Snakes wake up from their winter sleep. Breeding occurs in the ponds and within the reedbeds along the River Mole. Unlike frogs, Toads lay their eggs in long strings.

April

Bluebells - Hyacinthoides non-scripta. Horleyland Wood

Found throughout the woodlands at Gatwick, this ancient woodland indicator species crates a heady scent on warm spring days.

May

Not a mirror image, but in fact a mating pair of Eyed Hawk-moths Smerinthus ocellata, spotted by Tom Forward along the River Mole grasslands.

June

Grass Snake  - Natrix helvetica

Our most common reptile species at Gatwick; widespread across both sites but they are particularly found of the grassy margins of scrub areas.

July

Platystomos albinus - (a type of fungus weevil)

This is a Nationally Notable B species, found in a well-rotted pile of oak and willow logs. It may not seem obvious from the pic, bit this little dude measured only about 1cm from nose to rear! (Thanks to Graeme Lyons for correcting my I.D on this one).

August

A colony of these Willughby's Leafcutter Bees (Megachile willughbiella) set up shop in a bee hotel constructed by Tom Simpson's volunteers.

September

Harvest Mouse - Micromys minutus

One of our smallest mammal species, these tiny mammals weigh in at around 5g. Their nests
are commonly found in the reed beds along the River Mole.

October

Brown Long-eared bats - Plecotus auritus

Arguably the cutest bat species on site, they often utilise the bat boxes in the Land East of the Railway Line. In order to open and check bat boxes, a licence holder must be present, which in our case is ex-air traffic controller Martyn Cooke.

November

Eyelash Cup Fungus - Scutellinia scutellata. Upper Picketts Wood

These tiny and beautiful fruiting bodies are commonly found on very damp, well-rotted wood.

December

Tawny Owl - Strix aluco

It just so happens that Tawny Owls are the subject of a current BTO survey, which members of public can also join in on.

Happy New Year everyone and all the best for 2019!!

Bat activity transect C, Land East of the Railway Line, July 11th 2015

It has felt like a good year for bats around our biodiversity sites, with lots of exciting acitvity monitoring by Laurie Jackson, Martyn Cooke and volunteers from Surrey Bat Group. We've been using 3 different survey methods here: activity surveys (walking set routes called 'transects', with bat detectors and recording equipment); trapping surveys (with Martyn's harp traps, loud speaker and bat call software system); and box checks (annual checking and cleaning of our woodland bat boxes).

Although rarely seen, bats actually make up around a third of UK mammal species and so are a significant players in our ecosystems. Also being insectivores, they are directly affected by any crashes in invertebrate populations and are great indicators of our countryside's overall health.

This recording equipment is all a bit beyond me, but Martyn Cooke (who also works in air traffic control at Gatwick) loves his tech and is a dab-hand at collating and translating this data.

Measuring the forewing of a Common Pipistrelle.

(To handle bats, you must be trained and hold appropriate licenses.)

Weighing a Pip in a cup

The biometric data collected includes the species type (some can only be identified by close examination in the hand), weight, sex, rough age, breeding condition and general health of the individual. I need to check again with Martyn, but I think we are up to 10 different species of bat recorded at Gatwick.

Assessing wing joints and bone ossification to gauge the age.

This health check might look pretty intrusive for a bat, but they are only kept for a few minutes before they are released back out into the night.

Common Pipistrelle (Pipistrellus pipistrellus)

Brown Long-eared (Plecotus auritus)

Bats face many threats due to extensive habitat loss and fragmentation from development, as such they are all protected by UK and European law. You might associate bats with roosting happily in buildings, but they really need natural features such as grasslands, hedgerows and woodlands to hunt and forage in. The monitoring and conservation efforts led by organisations such as Bat Conservation Trust are of vital importance to conserve the UK's bat species. 

Get out of here, you.

Its not always deemed socially acceptable to be out in the woodlands after dark. but this bat work gives us special licence. Its also great to see and hear all the other wildlife out and about our biodiversity areas on warm summer evenings:

Light Emerald Moth (Campaea margaritaria)

Glow Worm (Lampyris noctiluca), female

We often hear the strange hoarse squeaks of juvenile Tawny Owls, which sound like their voices are breaking...

Plus a rather impressive (and one of my favourite) species we have resident in our woodlands...

Araneus angulatus male, a rare spider in the UK, restricted to the southern counties
