About this tells BBC News.
In total, 8 Galloway cows brought from Scotland will graze on the natural area.
Ed Wombwell, property manager for Cambridge Past Present and Future, which runs the park, said the animals' small size and undemanding diet made them ideal for grazing in the park.
"We have grasslands which are a fantastic biodiverse environment - both nationally and internationally - and the best way to look after such an area is to use grazing animals," says Wombwell.
It is known that the cows have successfully adapted to the new area and have already "cleared" one of the territories.
