There is only one reason why ramsons and 2751 other species are endangered

Nine out of ten species are endangered as a direct result of how we use Norway.

The ancient giant ash that clings to the wall around Halsnøy monastery in Hardanger is proof of the tree’s long roots in Norway’s history. Ash is now critically threatened with extinction – mainly due to the ash blight that people transported from Asia to Europe.

NEWS ANALYSIS: It shows the new the red list for Norway which the Species Data Bank has created.

New roads, modern forestry, new residential and industrial areas and massive cottage development are the most important reasons.

We can not blame foreign pollution or global warming, even if climate change becomes more important.

If all the 2752 endangered species become extinct, Norway will become poorer. But long before the species is finally extinct, nature’s ability to function is greatly reduced. Our nature also fails to give us what we need from it.

We need the wild bees and wasps to pollinate fruit, and the mosses on the bog like mushrooms after torrential rain. 31 percent of the wild bees and bumblebees are on the red list. Nature also provides a great many other ecosystem services. We should think about that every time we build in untouched nature. We do not.

Most species are threatened by several different conditions. One cause often reinforces another. First we make it more difficult or impossible for species to live where they have always lived, then climate change or new alien species come to the fore.

And species can no longer cope. Many of these endangered species have in fact become extinct already. Only the remains cling.

Many species are even endangered because we have stopped using nature as we used to.

The violent harvest of ramsons, especially in the Oslo area, has brought the good spice plant onto the red list as “near threatened” for the first time.

These are the main reasons:

If we are to save the endangered species and prevent more people from ending up on the list, we must think differently every time we build something new. Nature is not an inexhaustible resource, even though only two percent of Norway’s area is built up. But very little Norwegian nature is allowed to be completely at peace.

Forestry is the worst: As many as 1330, or 48 percent, of the endangered species live in forests. And very many of these beetles, felts, lichens and fungi are endangered due to modern forestry with large felling areas. Also nature-friendly harvesting is blamed for the fact that many species are endangered.

Housing construction in the wild is the main reason why 341 species are endangered. Development of roads and railways threatens 316 species and development in connection with recreation and tourism threatens 199 species, according to the new red list. Often these are species that live in small concentrated areas that we humans choose to use for development.

Agriculture is a direct cause of 397 species being threatened with extinction, primarily through new cultivation and drainage. But as many as 513 species are threatened by the opposite, namely that former agricultural land grows again and that the grazing animals are gone.

Damming in watercourses has led to 122 species being endangered and backfilling of ponds is the main reason why 119 species are endangered.

Different pollution threatens 377 Norwegian species – for example 63 fungi on land and 43 beetles in freshwater.

Climate changes is the main reason why 211 species on land and in the sea are threatened – a sharp increase from 91 in the previous red list from 2015. 31 birds, 78 mosses and 56 vascular plants are threatened by climate change.

As many as 254 species are threatened by other Norwegian species – so-called native species. Trampling and grazing from very large populations of deer threaten many species.

Alien species are negative for 153 endangered Norwegian species – up from 53 in 2015. For example, 16 seabird species are endangered by mink.

Hunting, trapping, fishing and gathering threatens 55 species. Chives, for example, have now become almost endangered due to extensive picking. We still hunt endangered species such as black tooth, eider, heilo and hare.

The species database never interferes with how we use Norway. They collect data about the species, assess them, find the reasons why species are struggling and give us facts. They never hesitate to correct misjudgments when the facts change. Among other things, two previously “extinct” species have been changed this year to have viable populations – a butterfly that thrives best in maple trees and a clam that lives in deep water. The reason is increased knowledge.

This makes the Species Data Bank’s conclusions reliable. Facts without accompanying political wishes are most frightening.

There is still little basic research in Norwegian nature. Therefore, the knowledge gaps are still very large. Just as in the rainforests, this means that we are likely to exterminate species we have not yet discovered.
