In a bid to prevent the four-footed intrusions, a fence already exists on the Norwegian side, spanning 150 kilometers (93 miles) of the countries’
shared 198-kilometre border.

But some sections, dating as far back as 1954, have fallen into such disrepair that the animals can easily pass through and cross into Russia.

“It is strictly forbidden to cross the border into Russia, for reindeer too,” the Norwegian Directorate of Agriculture said in a statement.

Since the beginning of the year, 42 Norwegian reindeer have crossed the boundary to graze in the Russian national park Pasvik Zapovednik.

Each time it happens, Russian authorities demand some 50,000 kroner ($4,700) in damages and the animals are slaughtered on their return to Norway
to prevent a recurrence.

The Directorate of Agriculture has therefore ordered the construction of a new fence on a seven-kilometer section by October 1, at a cost of 3.7 million
kroner.

The reindeer — bred by the indigenous Sami reindeer herders that span northern Europe — are semi-nomadic and travel across vast expanses as they
move between their winter and summer grazing grounds.

In this Arctic region, Norway and Russia share just one authorised land crossing, the Storskog-Boris Gleb border point.
