Around the mid 1800s a farmhand from the Nisula estate, named Matti Juhanpoika arrived in the Jutimäki wilderness looking for a suitable place to set up a farm for his family. The young family found the Kovero area to be pleasant and right away a bit of field was cleared and a sauna, a barn for sheep, a barn for cows and the largest building the drying barn were built. The farm's lease was also put in order and so Kovero became a crown tenant farm, a rented farm on state-owned land. The family paid rent by either gaving a part of their harvest or with labour.
Matti's and Severiina's first son Nija was worn down by a lung illness and running the farm became overwhelming for the rest of the family. In 1878 the farm was sold to Matti Esaianpoika Liesijärvi. He adopted the house's name Kovero as his surname.
According to word of mouth Matti Kovero was a strong man. Together with his wife Anna and their children he worked the rented land. The fields and meadows grew in size and a new grand farmhouse was built, but the family still did odd jobs to earn additional income: logging work and offering lodging to travelling workmen. The area's forested parts were often called forestry's promised land. The income offered by logging brought timber jacks from far and wide to the area. Lodging was in great demand and the men often stayed in local homes.
In 1902 Matti handed the farm over to his son Ananiaa. Niia and his young bride Aleksiina started to run the farm, Matti and Anna were set for life: as when they retired they stayed at Kovero. According to the retirement agreement made, Matti and Anna were entitled to live in backroom of the main house, to keep a few cattle and to get things such as meat and shoes from the house.
Niia and Aleksiina were blessed with seven daughters and one son. Their son, however, lived only a few months and one of their daughters died when she was 10 years old. Aleksiina died of "her lungs withering" in the winter of 1925. On top of logging work and farming the fields Niia was left to deal with taking care of the livestock, household chores and caring for the youngest children. A new wife was more than needed. With the help of a speaker a need marriage was arranged and so Aliina and Niia were wed in 1926.
When the farming act was legislated in 1923, farmers began to purchase estates for themselves. Independence was considered at Kovero as well, but due to land surveys and appeals becoming drawn out the purchase was delayed until 1931.
Wartime had little effect on Kovero, as no one from it joined the draft. The death of Matti, Niia's father, caused great sorrow during the interim peace, but his daughters' weddings in turn great brought joy to the estate. The younger daughter's wedding was celebrated on Pentecost in 1946. Even though times were tough after the war the tables were laden with food and not even the thirst of four hundred guests emptied the beer barrels.
Kovero's heyday, however, came to an end during the wars. The farming boom after the wars had little effect on the lives of those at Kovero: the estate did not begin to use electricity and the fields were not drained with ditches. Upkeep of the farm which was dwindling came to a complete halt when Niia died in 1952.
The farm's fields and buildings were sold to the state in 1970. The fields were reforested and the buildings were left abandoned. When Seitseminen National Park was established in 1982 Kovero was annexed to the national park. In the national park's framework Kovero Crown Tenant Farm was appointed a cultural landscape (www.metsa.fi). The farm's buildings and fields, as well as the surrounding meadows and forests form a valuable man-made heritage landscape, the conservation of which has been ensured by appointing it one of the park's sights. The farm was restored as precisely as possible to resemble a 1930's farm and is maintained by traditional methods. The heritage landscape, which was born due keeping of cattle and cultivation of the land, are maintained by grazing: during summer cows indigenous to Finland wander in the farm's pastures and meadows. In addition to conservation of buildings and nature one of the main objectives of Kovero is to tell of life in the olden days.
