International Day for Biological Diversity - 22 May: Critical declines and vital signs of hope for Scotland's nature - Nature Scot

Scotland is widely known for its biological diversity (variety of nature), and as we approach this significant day, NatureScot’s latest report highlights the changing picture of nature across the country.

Species for which we hold internationally important populations, such as seabirds, have declined markedly (down 36% since 1994), and similarly populations of terrestrial or land based animals have also shown a significant decline overall (31% since 1994), although birds and butterflies are holding their own.

Bryophyte species, which include mosses and liverworts, are good indicators of habitat quality and now occupy 40% more sites than they did in 1994. There are signs that pollution sensitive species have been amongst those showing strong recovery. However lichens, which also suffered from historical pollution, are 14% down.

David O’Brien, NatureScot’s Biodiversity Evidence and Reporting Manager said: “The climate change crisis means many of our internationally important species are in critical decline, highlighting the crucial need for action. It’s not too late – mosses and liverworts can be the ‘building blocks’ that help sustain habitats for our other plants, mammals, birds, butterflies and moths – and their health is a sign of hope. Not only do we hold globally significant concentrations of mosses and liverworts, they perform important services from which we all benefit, such as slowing rain run-off and hence reducing flood risk, as well as making peat which captures carbon.”

The drivers of change are discussed in the full report Marine and Terrestrial Species Indicators: Experimental Statistic and include land and sea use change, climate change, pollution, invasive species, and natural resources and exploitation. The new indicator will help NatureScot understand drivers of decline and provide opportunities to focus conservation efforts.

The Scottish Government has extended Scotland’s Marine Protected Area (MPA) network to cover more than 37% of our seas, announced plans to protect at least 30% of Scotland’s land for nature by 2030 and increased investment in nature-based solutions such as peatland restoration and woodland creation, reflecting the increased urgency for action to tackle the twin crises of biodiversity loss and climate change.
