Biodiversity net gain - what does it mean?
Biodiversity, the diversity and richness of species, is currently under threat due to climate change, habitat loss and invasive species. The rapid extinction of species in recent years calls for more action to mitigate the effects of human activities on biodiversity.
In 2019, the UK government announced that all newly developed sites in England would have to show a net 10% gain in biodiversity. This means that after the development of a site is completed, biodiversity should be 10% greater from the baseline.
How exactly is biodiversity measured? When measuring biodiversity, we take into account:
(1) How well the site is connected to other sites of high levels of biodiversity,
(2) The significance of the site - the richness of species that are present there
(3) The condition of the site
(4) How important it is at the national level.
The measurement of biodiversity post development also accounts for the time it takes for the biodiversity to establish, and for the impact of the site on nearby areas. As the process of construction may come with a cost, this is also considered.
The New Museums Site aims to achieve the 10% biodiversity net gain. Main ways of enhancing biodiversity in urban areas are:
(1)Including green roofs and walls in the building
(2)Setting up bird and bat boxes and insect hostels
(3)Providing open areas
Stay tuned for more posts to come on how we can enhance urban biodiversity using these tools!
