  • The LBC Enewsletter - February 2020
    The Heron - Lincs Bird Club eNewsletter 2020 - February 2020 Welcome to the LBC eNewsletter - February 2020 eNewsletter Content; Willow Tit Survey 2020 1 2019, a County year by Ben Ward 6 LBC AGM 3 Killer Whale in The Wash! 11 Barrie Wilkinson Talk 3 Other News and Events 15 Vacant WeBS Sites - Holbeach 5 Lincolnshire Bird News - Jan 2020 16 2020 Willow Tit Survey The decline of the Willow Tit is well known. It is our most threatened resident bird having declined by 95% since the mid 70s. As an endemic race, the British Willow Tit is indigenous to Britain and found nowhere else. Its disappearance would be a slap in the face for all British conservationists. We've been charting the decline year by year in the Lincolnshire Bird Report and it has accelerated over the last 5 years. The RSPB recognising that they need to step in and do more to prevent the extinction of this species started a national survey in 2019 which will continue into 2020. Knowing exactly where Willow Tits have been and are now is crucial to understanding how they might be saved. We will be supporting the RSPB by following their methodology and surveying the tetrad squares they have identified as worthy of checking. Some of these squares almost certainly no longer hold birds but have done over the last 20 years or so. Negative results are useful as well as positive ones so please check squares near you even if you are pretty certain there are no Willow Tits present. The methodology requires a visit to suitable habitat in each tetrad twice during mid February to mid April and the use of playback to determine if Willow Tits are present.

  • DTE East Public Information Leaflet
    PUBLIC INFORMATION LEAFLET DTE East FACILITATING TRAINING AND PROTECTING THE ENVIRONMENT DTE East WHY THE ARMY NEEDS TO TRAIN The British Army is held in the highest regard around the world. This respect has been hard-won over recent years in Northern Ireland, the Falkland Islands, the Gulf, the Balkans – and countless peacekeeping operations throughout the world. But such professionalism does not happen by chance. It is attained by constant, thorough and tough training, in realistic conditions. The Defence Training Estate (DTE) provides the principal facilities to achieve this. ORGANISATION The Defence Training Estate in the UK is controlled by Headquarters DTE, based at Land Warfare Centre in Warminster, Wiltshire. The Estate is sub- divided into 12 regionally-based areas, each with its own Headquarters and staff. DTE East (DTE E) consists of Stanford training area and ranges, East Anglia training area with its Colchester-centred facilities, and East Midlands to the north of the region with its similar amenities in Lincolnshire, Northamptonshire and Nottinghamshire. TRAINING IN DTE E DTE E was formed in 1999, and hosts units from many other parts of the UK, who come to take advantage of the particular facilities we can offer them. At Stanford training area, approximately 340,000 man-training-days are carried out annually by the Regular and Territorial Army, Cadet units from all 3 services, police forces, and overseas forces. East Anglia training area includes Colchester, the ranges at Middlewick and Fingringhoe, plus Barton Road, and a dry training area (i.e. without live firing) at Stradishall disused airfield. Finally, East Midlands training area includes facilities at Beckingham, Fulbeck, Yardley Chase, and Dukeries.
