In January 2020 the Dundee Biodiversity Action Plan was produced. This plan has a list of actions that combine to help us attain the vision of 'Working together to protect, enhance and raise awareness of biodiversity in Dundee for the benefit of all.'
The Grassland chapter in the Biodiversity Action Plan highlights that a large proportion of grassland in Dundee is amenity grassland, which has the lowest potential for biodiversity. This is why one of the actions in the plan is to 'Review grassland management across the city. Increase in the amount of grass managed to improve biodiversity.'
By leaving some grass areas to grow longer before cutting them, or by not cutting areas at all, we will allow our native wildflowers a chance to grow and flower. This should help turn these areas into low maintenance grassland which can have medium potential for biodiversity or semi-natural wildflower meadow, which has high biodiversity potential and is recognised nationwide as a habitat that needs to be protected.
In the U.K., over 97% of wildflower meadows have been lost since the 1930s (according to UK charity Plantlife). When native wildflowers disappear, many invertebrates are lost too, including insects which are vital to pollinate food crops and rely on these wildflower areas for food or a home. In the UK the value of insect pollination to agriculture is £691m a year (Buglife UK), pollinating crops such as oil seed rape, fruit and vegetables and producing Scottish honey.
According to UK Charity Buglife, six of our 25 species of bumblebee have declined by at least 80% in the last fifty years. These losses are mirrored for butterflies (71% of British butterfly species in decline) and hoverflies (38% of species in decline). This means that some unique and rare Scottish species are already irreparably lost and are on the brink of disappearance. Once such species are extinct, they will not return.
Losing vast numbers of insects and other invertebrates also has knock-on effects for other animals that feed on them including our native birds, amphibians, bats and other small mammals. One example are hedgehogs whose principal food source are insects and invertebrates.
As agricultural practices become more intensive, urban areas like Dundee, are becoming increasingly important for pollinators and provide many opportunities for habitat creation. Not only are flower rich grasslands good for biodiversity but they provide numerous other benefits such as capturing carbon, preventing flooding, reducing air pollution and providing aesthetically pleasing surroundings which contribute to the general wellbeing of people.
