Co - President - David Gilliland
At the Conference in Oct 2014 David resigned as Chairman and Dr Charles Nelson Proposed that David should be invited to act as Co - President.
At a meeting of the NIHGC on 21st Nov 2014 the Committee confirmed the appointment.

David is the owner of Brook Hall ArboretumBrook Hall, together with the Arboretum and walled garden, is set in a Woodland Park, which faces South East. The ground slopes down to the swiftly flowing River Foyle some two miles downstream from the City of Derry. In the 18th and 19th Centuries, large sailing ships departed from Derry carrying Irish immigrants to the New World, returning, weather permitting, laden with grain or timber. During the famous Siege of Derry in 1689, Brook Hall was the headquarters for King James' Army and the house was occupied by the Duke of Berwick who commanded the King's army. The original house was replaced about 1780, by an elegant Villa on an elevated site to the North of the original house. Extensive planting and landscaping took place at that time. Trees planted where mainly Oak (Quercus robur and Quercus petraea), Beech (Fagus sylvatica), Spanish Chestnut (Castanea sativa), Lime (Tilia x europea), Sycamore (Acer pseudoplatinus) and included a particularly fine "Lime Avenue" just above the walled garden. The new house was altered about 1816 when the balcony was added and it took on its appearance of a Regency Villa.The House and demesne was purchased by Samuel Gilliland in 1852 and is still in the ownership of the Gilliland family.

Neil Porteous - Head of Gardens, Mount Stewart and Regional Gardens & Parks Advisor, NI. I have been gardening now for 37 years and love my work – I could never do anything else. Horticulture is a boundless subject and I am always learning. I have worked in many gardens, both great and obscure, private and public. I have a BSc Hons in Landscape Management and an MA in Garden History. In my current role as Head Gardener at Mount Stewart I push myself to think differently, (Like the garden creator, Lady Londonderry), and I look outwards for new plants, new techniques and new ideas. My job is a vocation, sometimes eating into family time, but has been a great adventure with many new and exciting opportunities presenting themselves. I have little personal ambition, but a great ambition for Mount Stewart and the other gardens in Northern Ireland I advise.
