Beyond Our Borders by APHA
The garden demonstrates how iconic tree species, represented by British oaks, grown in botanic gardens around the world, are being monitored to help identify new plant pests and diseases indigenous to that zone, which could threaten native plants from other countries (for example, the UK).
The garden is split into three zones by water features signifying the oceans. Set within the planting are coloured slinky toys, representing the ability of plant pests and diseases to move from zone to zone, reflecting the threat to plant health. As the slinkies progress towards the water trays they morph into pulsing lights that travel through the water, demonstrating risk pathways via global plant trade.
