Rein­de­er popu­la­ti­on has dou­bled sin­ce 1994

Local rein­de­er popu­la­ti­ons in several important val­leys near Lon­gye­ar­by­en such as Sem­mel­da­len, Cole­s­da­len and Advent­da­len have dou­bled sin­ce 1994, and this trend is belie­ved to app­ly also to other parts of the Spits­ber­gen archi­pe­la­go. The rea­son is thought to be a 2 degrees incre­a­se of sum­mer tem­pe­ra­tures which have led to stron­ger growth of vege­ta­ti­on. On the other hand, ins­ta­ble wea­ther pat­terns have led to a hig­her fre­quen­cy of bad years with star­va­ti­on and a loss of parts of the popu­la­ti­on. The average weight of the indi­vi­du­al ani­mals has decre­a­sed slight­ly (about 1 kg). 2012 is likely to beco­me the fourth bad year for rein­de­er sin­ce the begin­ning of the obser­va­tions, which inclu­de popu­la­ti­on sur­veys and the exami­na­ti­on of rein­de­er jaws which are deli­ve­r­ed by hun­ters.
