Evolution of virtual fencing designed for grazing beef cattle opens up new opportunities for available rangeland and grassland areas. Virtual fencing has the potential to reduce the amount of labour required for fencing, increase the flexibility of fencing to adapt to changing pasture conditions, improve precision and efficiency, and provide more options for grazing management. Taking into account this promising perspective, we have started the project ProEcoFarm which main objective is to produce top-quality culinary beef based on a model of farming suckler cows in a pasture-based feeding system on extensive grasslands located in high nature value areas using an Internet of Things (IoT) system. The experimental pasture is located in the Middle Odra Valley in Western Poland in the complex of semi-natural grasslands under protected area of Natura 2000. The study has been carried out from 2022. The grazed area of 27.5 ha is characterized by high diversification of botanical composition as a consequence of mosaic soil habitats of the pasture. We noticed occurrence of 48 species and 7 grass communities. Based on the monthly monitoring of the pasture during vegetation periods the biomass yield ranged from 0.8 to 2.7 t DM per ha, depending on the grass community. The study area is grazed by Limousine suckler cows by stocking density below 0.5 LU per ha. We conclude that for cattle grazing in high nature value areas the building of conventional fences are often impossible or/and not welcome. The remote control of the cattle herd using collar-mounted devices will make it possible to exclude areas with protected plant or animal species from grazing without building physical barriers. It is worth noting that an essential part of the technological innovation is determining grazing areas according to the cattle's feeding group classification.
