Renna, who fall prey to wolverines, wolves and lynx, are equipped with sensors for their protection.
It makes it easier for the shepherds to keep track of animals around the remote forests of lapland where you are.
Sensors around the neck of the female reindeer are connected to the shepherds smartphone, allowing them to save hurt animals more quickly and identify the cause of death for those who were killed.
The next year, the team behind the system also provides for monitoring of the predators.
Up to 10% of reindeer is lost every year in road accidents or by falling prey to bears, wolves and wolverines.
The predator par excellence, for the reindeer are the lynx, and there is a plan to try to keep track of them in 2018 to identify when they are in close proximity to farms.
The reindeer sensors have been connected to a selection of animals at the bi-annual reindeer round-up in the month of September.
The shepherds discovered that it was better to put the tracker on the alpha females, to enable them to better locate the whole herd.
The tracker uses GPS satellite signals to determine the location of the reindeer, which is communicated to the farmers’ smartphones via a low power, specially designed network that eliminates the need for each device has a mobile subscription.
Matti Sarkela, head of the Finnish Reindeer Herders’ Association, said: “We have great expectations of the internet of things”, adding that the main challenge is that today’s sensors are still quite big.”
“We need a sensor that lasts a year, low cost, and with better tracking technology, it can be difficult to get good GPS signals in the high Arctic. We are now working to find the best mix of technologies and achieve the best sensor.”
The current sensors were provided by the ‘ internet of things company Actility, while the Finnish company’s Digital communications has begun deploying a range of network nicknamed LoRaWAN last year to provide coverage for some of Lapland’s most remote forests.
The mapping and display of the software, comes from the Finnish start-up Mapitare, who started life creating offline-enabled maps for the emergency services.
Reindeer herding is big business in Lapland, with a maximum of 300,000 animals handled each year, generating $25m (Â£19m) from the meat, fur and antlers products.
The reindeer spend the majority of their time in the wild, roaming where you can choose which puts them at risk.
Last month, 100 reindeer were killed by a train in a single incident in Norway.
Mr. Sarkela said: “This tracking solution brings real benefits for the reindeer and for our pastors.
“There are obvious ones, such as the rescue of injured animals, or to confirm the death of an animal, to ask for compensation, but by tracking all the time, we are able to obtain information about their behaviors and the best care for them.”
And, he added, the technology could help make the “life” of the herder easier”, which in turn makes it more attractive to the younger generation.”
It is not the first time that the association has to be shot with the technology.
More than 10 years ago they began to use the GPS, and three years ago has launched an application for smartphones called Porokello (reindeer bell) that allowed drivers to report that the reindeer in close proximity to the streets and send alerts to others.
