Impact of climate change on Finland species and Species distribution

The species that are mainly going to be affected in Finland as climate change bites on are those that have aero-mobility – like birds and insects. In Finland there have been observations of birds over a long period of time and it has been observed that many migratory species of birds are coming into Finland and are breeding on an average of about 7 days earlier than a couple of decades ago. This can be to bird’s advantage to arrive earlier and nest on time, making the birds to produce more young than later arrivals. There is also a disadvantage to this early breeding because a long spell of winter period can be disruptive to the siblings.

Some of the species that presently arrive earlier in Finland to breed are said to be shorter-distance migrants. This is because the “earlier arrival of spring in these birds' nearby wintering areas is more likely to encourage them to migrate sooner in the expectation that conditions in their breeding areas will be suitable”.

Insect species are also affected by climate change in Finland. There has been irregular migration of insects from the north to the south. It has also been noticed that the number of insects in the south is even more than the estimated migrated numbers from the north. However a long spell of this kind of situation can cause a pandemic. Also, insect-eating species may also surfer the long spare disappearance of insect or extinction of insects. One of the insects that is very prone to weather factors in Finland is the greenfinches (Carduelis chloris).


Some of the plant and animal species that will be affected in Finland include: purple emperor (Apatura iris), polar fritillary (Clossiana polaris), the arctic fritillary (Clossiana chariclea), white-veined arctic (Oeneis bore), etc. Other species that will also be affected will include butterfly and moth species.
