equipment specialist Trimble, who were working on a system using Real Time Kinetic (RTK) and GLONASS signals to give machine guidance within 2cm accuracy. “The system hadn’t been launched at the time in the UK, but the company worked with us to get the technology right. Our drivers have an RTK receiver on their machine and a display screen which shows exactly where they are working and if any sensitive features are close by.” Preparing the full 5,800 metre
cross country track, which loops around the park and, in places, widens significantly to accommodate combination fences or those with alternative routes through them, involved mainly standard turf establishment equipment and techniques. After aerating and decompacting
the existing surface, an improved sward was planted with a drill seeder, and then irrigated and fertilised. But, at every stage, the constraints of the site had to be considered. “We were only able to decompact to a set depth, and it was not always possible to use heave because of archaeological features and works,” explains Lee. “So, it has to be an ongoing process to get the benefits of decompaction, and the GPS equipment has been vital to identify vulnerable areas.”
The course was seeded with a single variant of ryegrass to avoid the spread of invasive species such as fescues into the native grassland. During the reinstatement phase, ryegrass selective herbicide will be used to kill off the rye and restore the turf to acid grasslands. Irrigation of the ten metre wide
