  • Report on Rare Birds in Great Britain in 1996 M
    British Birds Established 1907; incorporating 'The Zoologist', established 1843 Report on rare birds in Great Britain in 1996 M. J. Rogers and the Rarities Committee with comments by K. D. Shaw and G. Walbridge A feature of the year was the invasion of Arctic Redpolls Carduelis homemanni and the associated mass of submitted material. Before circulations began, we feared the worst: a huge volume of contradictory reports with differing dates, places and numbers and probably a wide range of criteria used to identify the species. In the event, such fears were mostly unfounded. Several submissions were models of clarity and co-operation; we should like to thank those who got together to sort out often-confusing local situations and presented us with excellent files. Despite the numbers, we did not resort to nodding reports through: assessment remained strict, but the standard of description and observation was generally high (indeed, we were able to enjoy some of the best submissions ever). Even some rejections were 'near misses', usually through no fault of the observers. Occasionally, one or two suffered from inadequate documentation ('Looked just like bird A' not being quite good enough on its own). Having said that, we feel strongly that the figures presented in this report are minimal and a good many less-obvious individuals were probably passed over as 'Mealies' C. flammea flammea, often when people understandably felt more inclined to study the most distinctive Arctics. The general standard of submissions varies greatly. We strongly encourage individuality, but the use of at least the front of the standard record form helps.

  • To Download the Trail Publication
    IntroductionI Step into Ballymena's past with self-guided Churchyard Trails The Ballymena area is dotted with a diverse range of churchyards reflecting the fluid and constantly evolving nature of religious sites from the late 400s onwards. Each site offers a different experience and has its own unique story to tell within the wider history of the area. This booklet features two distinct trails. Pre-Reformation Trail The Pre-Reformation Trail explores the history of some of the oldest remaining traces of built heritage in the area. It highlights sites that have been used for Christian worship from the time of St Patrick and before the formation of the Protestant faith in the early 1500s. Covenanter Trail The Covenanter Trail delves into the distinctive history and associated sites of the 'Covenanters', or Reformed Presbyterian Church, in the local area. Covenanters were named after the National Covenant and the Solemn League and Covenant signed in Scotland in the mid 1600s. In 1644 the Solemn League and Covenant was brought to Ireland and signed in 26 places across Ulster, including Ballymena. These documents declared Presbyterianism to be the only true form of church government and insisted that the King should have no authority over the church.

  • Belfast Harbour, Northern Ireland
    CASE HISTORY Ref: INT/ UK / CH / BP016 — Rev:01, Mar 13 BELFAST HARBOUR Belfast, Northern Ireland BASAL REINFORCEMENT Product: PARALINK® Problem Ground conditions at a 50 acre wasteland site at Belfast Harbour were so poor that a major programme of stabilisation and improvement was required to allow the construction of a £50m transshipment and storage facility required to support the offshore wind industry. The riverside site which is next to Belfast’s George Best Airport and close to the City’s Titanic Quarter is the largest in the Harbour’s 400 year history. The project is part of a joint venture between Dong Energy and Scottish Power Renewables to support the construction of the West of Duddon off shore wind farm. Stabilisation and strengthening of the upper ground formations was needed as the facility was to be used for the off lading storage and assembly of huge wind turbine components. Large tracked cranes would be used to move equipment and materials about the site and at full capacity During installation would impose extreme loads on the surface. Solution Engineers devised a scheme which involved surface build up of up to 2m depth in places using a combination of site won fill and over 250,000 tonnes of imported stone. This was placed in layers over an array of Maccaferri PARALINK®, soil reinforcement geogrid approximately 1.3m below the finished surface. Over 400,000 sq m of PARALINK® were used and placed in two layers set at 90 degrees to achieve maximum reinforcement of the unbound granular layers. Maccaferri worked closely with the construction team throughout the project and helped streamline the installation programme by supplying the rolls of PARALINK®.
