A
number of Scandinavian trees survived the previous Ice Age, demanding
an extensively detained idea that they were killed off by the enormous
ice piece that covered the area. According to the research, several
conifers survived on peak peaks that protruded from the massive ice
piece, on islands and in coastal areas.
Present
groups of spruce and sulk that survived the cruel climate in tiny
ice-free pockets, or in refuges, as we call them, for tens of thousands
of years, and then were able to spread one time the ice retreated. These areas must have provided sites for roots to anchor and trees to grow in the challenging weather.
