September Summary: New beginnings

This has never been my favourite time of year as it usually signifies the end of things – life slows down, flowers disappear, invertebrate diversity drops, the grass turns yellow, evenings creep in earlier and the mornings take their sweet time to get going. Migrating birds, such as Swallows and Martins, ram this point home by flying thousands of miles, risking storms, starvation and predators just to get away from it all. This time last year, sitting in my portacabin next to an aircraft hanger, a sense of poignancy pervaded.

However, this year feels a little different as September has signified the beginning of new things. With the added help of other naturalists I have been squeezing in as many different ecological surveys as possible and we still have some exciting new ones to come including fungi, small mammals and pond invertebrates. I have been trying to cover as wide a range of species as possible.

The removal of American Signal Crayfish continues in a section of the River Mole - they love the spam.

The most commonly found species in our dormouse boxes - a Copper Underwing Moth

So there is life out there other than Craneflies!

The two main components of our Biodiversity Action Plan consist of monitoring wildlife, then hands-on conservation work to improve habitats. As the main survey season ends, our autumn practical tasks are kicking off with activities such as dead-hedging, reptile and amphibian hibernacula construction (a dug pit filled with rubble, logs and brash) and thinning out of old and dense tree plantations.

space for the remaining trees to reach their full, healthy potential...

...also allowing the sun's valuable energy to strike the woodland floor, benefiting groundflora and fauna

Our first airport staff volunteers of the season were the Accounts Payable Department, lead by West Sussex County Council's Volunteer Co-ordinator, Darren Rolfe and assistant Tom Weedon. The day was a definite success; no wind, no rain, no trees dropping onto volunteers plus only one piece of equipment went missing in the long grass - must be some kind of record!

I joke of course, all our volunteer days go more than smoothly here. This group were a fantastic bunch with bags of enthusiasm and together they made a great difference. I must say I’ve never seen conservation workers so well kitted out, I mean, a cafetiere in the middle of a field? Fair play... mine's an espresso macchiato, please!

Gatwick Greenspace Partnership (GGP) of the Sussex Wildlife Trust are the main conservation group here, carrying out community and environmental projects in and around Gatwick. I hear it has been nearly 20 years and they are still going strong. So when's the party, guys?
   Another aim of ours is to increase local awareness of GGP's work and to strengthen ties with the airport's numerous departments. Earlier this month, we set up a communications stand at the British Airways offices at Jubilee House, demonstrating the conservation works around Gatwick in order to engage the staff.

Phil Townrow, aka 'Phil the Bin', also joined us on the day: an interesting British Airways engineer who is green of mind and passionate about reducing the environmental impacts of aircraft operations, through projects such as aircraft waste recycling and biofuel production. Another example of how much is going on behind the scenes of an international airport and how little is known about it!


British Airways has ground-breaking plans for a biofuel plant, due to start operating in 2015

And so looking ahead there will be no time to relax in October, with a final push on reptile and mammal surveys, a jam-packed conservation schedule and a brand new Gatwick Greenspace team member joining the ranks; the pace is now picking up on Gatwick's Biodiversity Action Plans.

“You’re gonna need a bigger boat.” - Autumn/Winter habitat conservation

River Mole floodplain grassland during most of the summer


The ecological field surveying at Gatwick came to a close in autumn 2012 and it was declared one of the wettest summers on record... So a rather problematic first field season for me, then again even some of the hardiest ecologists I met along the way were suffering from dampness-doom! But enough about the wash-out summer, what then goes on during the autumn and winter once the final reptile and grassland surveys have been carried out?

The focus then switches to our first set of actions outlined in the Biodiversity Action Plan. From hedgerow-restoration to dormouse box installation, a new grass-cutting regime to scrub and woodland coppicing, we have now got the ball rolling on improving these habitats to benefit biodiversity.

They say that a rolling stone gathers no moss, but what about when it hits the mud? ‘Challenging’ is the word I would use to sum up this conservation task season! There was very little chance for the land to dry out over summer, so the autumn and winter kept all our natural areas in the constant state of wetland. Habitat management became expeditions with teams of people, heavy equipment and large vehicles which were needed to get as close to a boggy woodland ride as possible. When four wheels wouldn't cut it, trucks were abandoned and it was down to the trusty wheelbarrow...

However vehicles and equipment have their limits… 

A shuffle of our action plan schedule and we crack on with an alternative task. When it comes to biodiversity works it is a case of adapt to survive!

Our main habitat and conservation works this past autumn and winter:
•             Grassland cutting and collecting
•             New stock-proof fence and gate installation
•             Dense woodland and young plantation coppicing/thinning
•             Footbridge and fingerpost installation on public footpaths
•             Creation of woodland glades and opening up woodland rides
•             Hedgerow restoration and hard cutting-back
•             Rotational scrub coppicing
•             Pond and stream bank scrub management
•             Black Poplar tree planting along the River Mole
•             Habitat creation: nest boxes for dormice, hibernacula for reptiles and amphibians, dead-hedging and piling up deadwood for invertebrates
