The four animals were introduced last week and are due to stay for ten weeks. They graze on invasive plants such as nettles and prepare the ground for wildflowers later this year without needing to use machines or chemicals as humans might to get the same effect.
Borrowed from Maydencroft Farm in Hertfordshire, the two adult cows and two calves, will live in two enclosed areas, the Arboretum paddock and the Oak, surrounded by electric stock fencing. They will get daily checks from staff and a weekly visit from farm staff to check on their wellbeing.
Quadron’s senior contract manager, Ben Binnell, who is based in Holland Park said many Londoners had never seen a cow. "They are generating a huge amount of interest and are a fantastic addition to the park."
The cows are not the first animals introduced to the park. The council also used pigs in 2011 and 2010 but found they were not so successful at foraging on the Arboretum’s terrain.
Quadron counts the Royal Borough of Kingston upon Thames, Southwark and Hammersmith and Fulham councils, Birmingham City Council, Bristol City Council and Paragon Community Housing Association among its other clients.
