## Summary

The Snowdonia National Park Authority, known in Welsh as Awdurdod Parc Cenedlaethol Eryri, is undergoing an award stage in its procurement process for the project titled "Rheoli Rhododendron ponticum control - A496 Llanelltyd to Barmouth and A493 Dolgellau to Llwyngwril". This project falls within the industry category of works, specifically focusing on agricultural, forestry and horticultural services. Located in the picturesque region of Gwynedd, the initiative aims to address the invasive Rhododendron ponticum along several strategic roadways. Critical procurement dates began with the tender period ending on 15 March 2024, followed by an award period closing on 22 March 2024. The contract was signed on 30 April 2024 and is currently active, involving the successful bidder D H Roberts & Co, selected from four bids with a contract value of £16,000 GBP.

This tender presents significant business growth opportunities for companies engaged in environmental management, forestry services, and road traffic management. Organisations with expertise in invasive plant eradication would find this project particularly suited to their capabilities, given the need for coordinated oversight and management of Rhododendron ponticum. The successful contractor will have the chance to implement advanced site-specific methods, adhere to comprehensive health and safety protocols, and ensure compliance with road traffic management requirements. Businesses with robust certifications, including chainsaw and chemical spraying capabilities, as well as sufficient liability insurance, are well-positioned to compete for such contracts, enhancing their portfolio in public environmental projects.
