A bit of peas and quiet

By Katie McBride, Teacher of Biology

Growing season is well underway in the ODW vegetable patch. Maintaining or improving biodiversity is always at the forefront of our minds whenever we change or impact the land. With the veg patch, we try to incorporate companion planting to maximise our yield and help reduce pests naturally. Planting carrots next to our onions helps to work symbiotically to reduce carrot flies and onion flies on the respective crops, for example. Equally, we try to grow all our crops chemical free, so all our manure is provided by our own livestock and vulnerable shoots are protected with snug woollen wraps to deter slugs and snails. 

When selecting potential plants, we try not only to think of what will be good to use in the Bakehouse, but also to incorporate plants which serve a purpose in nature. Leaving beds of nettles and dandelions not only provide us with edible plants, but are also vital early food sources for bees and habitats for butterfly and moth larvae. Similarly, our circle of sunflowers will provide a beautiful vista of glorious colour and then fade back to an important natural bird feeder throughout the Autumn, and green manure can be turned back into the beds that have been rested.

We are ever mindful of the multitude of organisms we share our land with, and aim to provide suitable habitats for everything from fungi to tawny owls. Hence in the veg beds you might find the occasional decaying log alongside a line of beetroots, providing a great mix of fungi and habitats for the beautiful stag beetles, and our greenhouse has a resident slow worm who helps to keep the snail population in check!

Staying pesticide free allows us to ensure that nature thrives where it can, and we do not pass issues on up the food chains within our ecosystem. It is not without its battles and frustrations of losing crops at times. Knowing that residing in our garden are the leopard slugs that help break down decaying matter, hedgehogs on snail patrol and robins waiting for us to uncover any centipedes makes it all feel much more of a team effort, and allows us to see the funny side when the shameless blackbirds pluck out our freshly planted shallots and proceed to play their own game of volleyball with them!

We still need to hold our breath when watering the tomatoes with a large scoop of comfrey tea, but the rewards will be reaped with a hopefully bumper crop later in the year. We hope that on Parents’ Day you might take a moment to wander through the veg garden, or pop into the ODW Farm Shop to sample and buy some of our produce. Whether you have a hugely productive market garden or simply a basil plant on the kitchen windowsill, we hope you get as much enjoyment from your moments of gardening as we do.

Biodiversity update – Moths

By Mary Shotter, Biology Technician

Moths are declining in the UK. Studies have found the overall number of moths has decreased by 28 percent since 1968. The situation is particularly bad in southern Britain, where moth numbers are down by 40 percent. Many individual species have declined dramatically in recent decades and over 60 became extinct in the 20th century.

These alarming decreases in moth populations are not just bad news for the moths themselves, but also have worrying implications for the rest of our wildlife. Moths and their caterpillars are important food items for many other species, including amphibians, small mammals, bats and many bird species.

The reasons for the loss of moths are likely to be many and complex, including changes in the way we manage our gardens, pesticides, herbicides and light pollution. Climate change appears to also be affecting moths.

However at Bedales moths appear to be doing very well. Over the last few months, I have been putting out a ‘light trap’ once a week to attract moths and have so far found just over 100 species, including 4 types of hawkmoth – elephant, pine, poplar and the giant privet hawkmoth which has a 12cm wingspan.

Many of the moth species we have at Bedales are masters of camouflage – such as the Buff tip, which disguises itself as a birch twig and the Flame which has evolved to resemble a broken stick.

My favourite to date has to be the wonderfully named Merveille du Jour which translates roughly as ‘the best thing I’ve seen all day’ –  pictured above (bottom right) merging into lichen on a fence behind the science department.

Many moth caterpillars feed on grasses and it appears that the policy of keeping  areas around the school uncut is reaping rewards for both moths and the many other species that depend on them.

Bedales, biodiversity and lockdown

Biodiversity

By Cheryl Osborne, Teacher of Biology

Lockdown will be one of those defining moments. We will all remember where we were and what we were doing. For me, it will be the transition from standing in front of a class of children in my lab, to sitting staring at a computer screen on my sofa – an alien world and one that I am not enjoying! However, it hasn’t all been bad. The stillness and quiet has let nature be heard and during lockdown both Mary Shotter, our Biology technician, and I have immersed ourselves in it.

Mary has taken a biodiversity study of the Bedales site, and I have been taking photos of the wildflowers during my daily walks in the vicinity of Bedales. From these walks, I have put together some wildflower quizzes that have been available on the B-More Teams channel. I have really learnt a lot doing this and seen flowers that I hadn’t noticed before. My husband and I have been lucky, living close to school and the Ashford Hangers. The unnerving quiet of a deserted A3, which we walked over daily in those early days, allowed the birds and the rustling of the trees to be heard and heightened our awareness of nature all around.

Biodiversity at Bedales

Bedales-estate

By Mary Shotter, Biology technician

Over the past few weeks, in collaboration with a group of Block 3 Outdoor Work students and the Sustainability Group, we have begun the huge task of cataloguing the school’s biodiversity.

We started with the Lake, where we discovered 28 different species of freshwater animals, including water boatmen, dragonfly and damselfly nymphs, whirlgig beetles and flatworms. A walk around the centre of the site revealed 38 species of tree and 19 birds, such as the green woodpecker and nuthatch. The use of a moth trap also showed there were 14 moth species in the wildlife garden behind the Science department, which is remarkable, considering it is late in the year.
