The International Union for Conservation of Nature (IUCN) Red List of Threatened Species collates the extinction risk of animal, plant and fungi species. It is used to gain an insight into biodiversity health and aid conservation decisions. The assessment lists species into one of the below categories:Not EvaluatedData DeficientLeast ConcernNear ThreatenedVulnerableEndangeredCritically EndangeredExtinct in the wildExtinct157,190 species have been assessed to date with over 44,000 species threatened with extinction.As the COP28 UN climate conference takes place in Dubai, the IUCN released an update to the list on Monday 11 December 2023 in the hopes of bringing attention to the link between biodiversity and climate change.The update included the first global freshwater fish assessment which found that one quarter of the assessed species are at risk of extinction. Freshwater fish are crucial to ecosystem function, human food provision and livelihoods. Threats to freshwater fish species are summarised in the table below.

Invasive species one of the 5 main drivers of biodiversity loss What are invasive species? Invasive species are those which are not native or indigenous to an ecosystem and have a negative impact on that area or other organisms around them. This is different to a non-native species which are usually introduced by humans and do not have the same negative impact with no threat to the area or other organisms.Invasive species are sometimes introduced accidentally but can also be purposely introduced by humans without realising the consequences. human activity is the biggest reason for the spread of these species.They are called invasive species because they can:adapt very quickly.reproduce quickly.harm property or the economy.harm or kill native plants and animals.cause competition for food and resources with native species.sometimes bring in diseases. Examples of invasive species Common invasive species in the UK include the European rabbit, grey squirrel, muntjac deer, American bullfrog and American mink. European rabbit (Oryctolagus cuniculus) Japanese Knotweed (Fallopia japonica) How much of a problem...

COP 27, COP 19, COP 15...what is a "COP" and why are they important? We have just seen COP27 all over the news, COP 19 ended last week and COP15 is due to take place in December but what is a “COP”? COP standards for Conference of the Parties, which is the governing body of an international convention, for example, climate change. COP is a global conference where world leaders, heads of state, scientists and non-government organisations meet to discuss, review and put the rules of the convention into place. COP 27 COP27 took place from 6 to 20 November in Sharm el-Sheik, Egypt. It was the 27th United Nations Climate Change Conference to discuss the action needed to tackle climate change. Prior to the start of the conference, there was controversy when Prime Minister Rishi Sunak announced that he was unable to attend and only 24 out of 193 countries has submitted their plans to the UN prior to the start of the...

Perhaps a happier note compared to some of our more recent blogs… The Dorset Climate Action Network has launched the Great Big Dorset Hedge Campaign in an effort to map, plant and join up sections of hedgerow across Dorset. It is hoped that this will promote biodiversity and encourage wildlife across the county. The long-term project aims to create a network of connected and managed hedgerows as wildlife friendly corridors and refuge areas, with the help of the local communities along the way. By inspiring communities to take part by becoming hedge surveyors, coordinators or planters and providing the relevant training it is hoped that it will bring people closer together as communities and closer to nature. Why are hedgerows so important? Miles of ancient hedgerows have been removed to make way for agriculture and development. Hedgerows are thought of by many ecologists as an ecosystem itself due to the range of biodiversity within. They provide a home for 80% of the UK’s woodland birds, hedgehogs, many species of bats, great crested newt, dormice and butterflies. The re-planting of hedgerows...
