At the end of island week this blog is about why islands are important for wildlife.

You may have heard the term biodiversity before - what does it mean? If you are not sure you can look it up in a dictionary to help!
Many islands, including Alderney, have much higer biodiversity than areas of the UK that are an equivalent size and have a greater variety of habitats.

The island of Alderney is surrounded by very fast flowing tides, which brings in all kinds of nutrients to our waters. This feeds the marine life that lives there such as fish which in turn supports the seabird and marine mammal populations here. Often the waters around an island are teaming with life - this is becuase there are many marine species that rely on cliffs, rockpools and tidal areas (we will talk more about this next week when we discuss habitats).

Islands are naturally isolated, meaning some very interesting and unusal species can be found here but the populations are also aften small and vulnerable to human disturbance or natural disasters. One human factor that is a particular threat to island life are invative species, can you think why?

Islands may also provide a stopping off point for species on migration, provide a food source on their journey which is what we are seeing with the newly created Alderney bird observatory where over 13,000 birds were ringed last year.

Why not design a poster with some information about one of the species mentioned in the news report on the overseas territories meeting? Include some information on the island they come from and why the need protecting - you can find more information here and even take a virtual tour of some of the islands!
