International Day for Biological Diversity
At BGS we have a series of initiatives aimed at promoting various species of plants and animals on our sites.22/05/2021
Today, 22 May 2021, is the International Day for Biological Diversity, an event initiated by the United Nations (UN) to increase understanding and awareness of biodiversity issues — a theme central to the UN’s development agenda as part of the Sustainable Development Goals.
At the BGS’s Keyworth site, we currently have a series of initiatives to promote various species of plants and animals and enhance both their amount and diversity. A small group of staff (the Wilding Group) have been working with our estates team and together have made huge progress.
Over the last few years we have been working on initiatives around site, including managing a former bramble patch that used to be the caretaker’s garden with a small pond. We chopped back about 90 per cent of the brambles to create some new habitats. The bramble (or blackberry) is good in small patches as it offers protection for nesting birds and for small animals; its flowers are a good source of nectar and the juicy black fruits are good food for birds and small mammals. The pond is a vital source of water for insects, birds and small mammals.
We have left areas of shrubby blackthorn, hawthorn and plum as small woodland in the caretaker’s garden. The trees are tightly packed, meaning there is plenty of shade and protection. In one small grassy area, restricted mowing has allowed spring flowers to pop up, including cowslips, bluebells, snowdrops and a beautiful patch of fritillaries. These spring flowers will soon give way to geranium, buttercup, daisies and dandelion.
A small area of the garden is centred on a magnificent white poplar; we have left a hedge of bramble and blackthorn and it provides a ‘secret’ garden for staff. This area currently has herb bennet, goose grass, nettle, chickweed, cow parsley and some three-cornered leek. In a few months, a long-forgotten Mirabelle plum will provide fruit for insects, birds and staff!
Welcoming our visitors
Our night camera has caught plenty of late-night visitors including a buzzard, sparrowhawks and hedgehogs. Other wildlife initiatives in the garden (and around the rest of site) include the installation of bird boxes, insect hotels and a toad hole, which is a hole dug in a shady spot and filled with rocks, which creates a damp, dark habitat perfect for various amphibians.
Holes cut into the new perimeter fence allow wildlife to pass through the estate, including hedgehogs, squirrels, shrew, rabbits and other small mammals.
Wildflowers and birds
Around the wider site, we are leaving 70 per cent of our lawns to grow over the summer months (‘no-mow’ areas) to promote wildflowers, which not only look lovely but provide food for pollinators such as bees to collect more nectar. The wildflowers include clover, buttercup, daisy, vetch, ox-eye daisy and our magnificent bee orchids. This spring we counted over 700 bee orchids on site and we are currently looking forward to seeing them flower in June.
We have also recently placed 10 bird-feeding stations around site and we regularly see blue tits, robins, dunnocks, blackbirds, long-tailed tits, sparrows and wood pigeons (to name the most common).
Plants along the Geological Walk
At the centre of the Keyworth site, a walk along the 130 m-long rock concourse takes you through geological time, starting with a three billion year old rock from the Scottish Highlands and moving chronologically through time to the last great ice age. We have recently added geologically relevant plants to the walkway, from the first vascular plants in the Devonian Period (more than 300 million years ago), represented by horsetails, to magnolias, one of the first flowering plants (around 20 million years ago). Pampas grass represents the first grasses and of particular note is a splendid monkey puzzle tree, which was common in the UK in the Jurassic Period.
In the future
During the year ahead we will be engaging with local wildlife groups so we can document and monitor our wildlife, hopefully adding more night-time cameras and undertaking mammal, bird and insect surveys. We will be increasing the numbers of bird and bat boxes on site and planting more native deciduous and berry- or fruit-bearing trees.
