      The House of Lords debated the threats posed by pests and diseases to native trees

      The House of Lords debated the threats posed by pests and diseases to native trees in the UK on Thursday 13 February. The Arboricultural Association has said it welcomes this debate. Stating that it is important to recognise that the arboricultural industry is equally as concerned with the threat posed to ‘non-native’ as to ‘native’ species. It particularly welcome the contribution of Lord Framlingham, who used his time to demonstrate the importance of utilising arboricultural expertise. A president of the Arboricultural Association from 1989 to 1995 and a lifetime honorary fellow, Lord Framlingham has long been calling for an enlightened…

      Ash dieback project launches International Year of Plant Health

      3,000 trees have been planted in Hampshire as part of a pioneering project to tackle ash dieback.   The UK’s first Ash Archive has been established using £1.9m of government funding. It is the culmination of projects spanning five years to identify ash with a high tolerance to the disease.   It is intended that it will provide the basis for a breeding programme of tolerant ash over time and will enable the development of orchards producing commercially available seed.   Today (17 January 2020), the government’s Chief Plant Health Officer will visit the project to plant one of the…

      New rules on plant health to come into effect

      New rules on plant health, designed to stop diseases spreading or jumping borders, will become effective on Saturday( 14/12/19). The EU Regulation 2016/2031 on protective measures against plant pests was steered through the European Parliament by UK member Anthea McIntyre, Conservative MEP for the West Midlands. It became law in December 2016 and is directly applicable in all EU countries from December 14. Miss McIntyre, Conservative spokesman on both agriculture and the environment, said: “Plant disease can have a devastating effect commercially, on biodiversity and the environment generally, so it was vital that we should make ourselves more resilient. “In…

      New hope for trees affected by ash dieback

      New research has identified the genetic basis of resistance to ash dieback in UK trees, opening up new avenues for conservation. Researchers from Queen Mary University of London and the Royal Botanic Gardens, Kew sequenced the DNA from over 1,250 ash trees to find inherited genes associated with ash dieback resistance.   The study, published in Nature Ecology & Evolution, showed that resistance is controlled by multiple genes, offering hope that surviving trees could be used to restore diseased woodlands, either by natural regeneration or selective breeding.   Professor Richard Nichols, author of the study from Queen Mary University of…

      Horse power arrives in Stanmer Park, Brighton

      A team of heavy horses are the latest recruits to the council’s countryside team at Stanmer Park.   Led by Dan and Jess Brown, the Comptois horses will spend the next three weeks helping to clear sycamore and ash trees thinned out as part of the park’s Woodland Management Plan.   Horses have traditionally been used to move logs from woodland to avoid using heavy machinery and minimise damage to the other trees and the forest floor.   The selective thinning of the trees will make space for planting a range of species and allow younger trees to thrive.  …

      Tackling the Toxic Caterpillar

      With reports of Oak Processionary Moth on the rise, Pro Landscaper finds out exactly what the tree pest is and how the industry is responding to the threat of it spreading across the UK A few years ago, the only place oak processionary moth (OPM) could be found in the UK was London. This year, though, the unusual tree pest is being discovered as far afield as Cardiff and Sheffield. Wolverhampton-based Boningale Nurseries is so concerned about it spreading that it has ceased importing oak trees, and the RHS banned the species from being brought onto the show ground at…

      Caution urged by growers and traders on oak imports

      A group of Horticultural Trades Association (HTA) traders and growers are urging importers to ensure oaks being brought into the UK not only comply with current legislation to combat Oak Processionary Moth (OPM), but are not sourced from Italy’s recently declared Pest Free Area (PFA).   The HTA are seeking guidance from Defra and awaiting confirmation that the proposed PFA meets the international standards for phytosanitary measures. Until this is confirmed, the HTA asks that UK businesses continue importing oaks that only comply with legislation which is designed to ensure that the UK imports OPM-free trees. Defra have confirmed that…

      Heather landscapes under threat due to climate change

      One of England’s celebrated landscape spectacles is suffering due to climate change. The impact of last year’s hot weather and increased pest activity has turned acres of heather from glorious purple to a muddy brown.   Through August and into early September, the hills at Long Mynd in Shropshire and at Holnicote on Exmoor are typically awash with a haze of purple.   But this year the National Trust, which cares for both landscapes, has seen up to 75% of the heather in poor health due to a combination of last year’s drought and damage from the heather beetle.  …

      VIDEO: Adur and Worthing step up action against Ash Dieback disease

      A task force has been created to help control a deadly disease which could wipe out all Ash trees in Adur and Worthing.   Ash Dieback has been discovered in trees at Lancing Ring in Adur and The Gallops at Findon Valley in Worthing. Almost 20% of the entire woodland covering is at risk – that’s estimated to be more than 1,200 of the species.   The disease, spreading across Europe, is currently incurable. This means the most common tree in West Sussex, Ash, could disappear from the landscape forever.   Adur & Worthing Councils’ parks team has been carrying out…

      Trees to be removed in Roath Park Gardens, Cardiff to deal with Oak Processionary Moth

      Evidence of Oak Processionary Moth (OPM) has been found on an oak tree in Roath Park Gardens in Cardiff as a result of proactive inspection by Natural Resources Wales of seven newly planted oak trees.   A Statutory Plant Health Notice was issued on the trees on 24 July, which requires the treatment and removal of the trees.   The infected tree in Roath Park Gardens were sprayed as a precaution using an insecticide on the evening of the 23 July and will be removed along with the other six trees today, 25 July.   The Welsh Government has said…
