The overall campus is 115ha and the university parks' team includes 17 people. "They do everything from laying paths, preparing ground for buildings and cutting hedges - last year we trimmed 4.5 miles of shrubs, mostly by hand," says site manager and head of landscape Jim Swan. "We drew up a five-year landscape-management plan to accompany the Green Flag Award application."
The lawn, historic garden and surrounding wooded areas were originally laid out as the formal gardens of a country house that dated back to the 15th century. Formal gardens were laid out in the 18th century in the prevailing picturesque style.
Later owners added collections of exotic trees and plants and the garden design is an overlay of several periods. Maintenance therefore has to take account of historical features, conservation, biodiversity, maintaining the mix of indigenous and exotic plants and supporting wildlife.
Since the university acquired the Riccarton Estate in 1969, care has been taken to safeguard the tranquillity and quality of this area. The site conservation committee is consulted on all aspects of landscape conservation, maintenance and management.
Today, key features of the site include a lawn dating back at least 200 years and containing more than 38 plant species as well as dome and drum yew trees. A grassed Velvet Walk bordered with yews, holly and laurel overlooks three mature woodland areas, stone walls and a private family cemetery.
"The university has published a series of booklets for visitors outlining the history, sculpture, landscape and tree walks," says Swan. "We hope gaining another Green Flag Award will encourage more visitors and recognise the achievements of the university and its partners in sustaining the historic gardens."
