Welcome to the LTOA website. The London Tree Officers Association (LTOA) constitutes the professional & technical voice for London's trees & woodlands. Its aim is to enhance the management of the Capital's trees.
We hope that you find the LTOA website both interesting & informative. If you have any questions, comments or suggestions, please do not hesitate to contact us.
On behalf of the Forestry Commission, the London Tree Officers' Association (LTOA) surveyed 2,979 London plane trees (Platanus x acerifolia) in 2014 for symptoms of C. platani. Inspections were undertaken at 53 sites across 28 London boroughs. More than half of the sites surveyed included potential hosts planted during the past 10 years, and the sites ranged in size from a minimum of 20 to, in some cases, more than 200 trees. No positive findings of C. platani were detected in any of the trees inspected.

A Green Infrastructure Task Force Report Prepared by the Greater London Authority on behalf of the Green Infrastructure Task Force. This is about a a vision for the Green Infrastructure of the future city. A high quality and well-maintained green infrastructure is integral to keeping the city healthy, happy, moving and functioning.
By 2050, all neighbourhoods will be able to benefit from, enjoy, and take pride in London’s green infrastructure.
The tree pest oriental chestnut gall wasp (Dryocosmus kuriphilus) has been confirmed in sweet chestnut trees (Castanea sativa) in a woodland in Kent.
A Forestry Commission spokesperson said:
“The oriental chestnut gall wasp has been discovered in one area of Kent.
“This is a pest that only affects sweet chestnut (Castanea) species of tree, and does not pose any risk to people, pets or farm livestock.
“We have launched an immediate investigation of the surrounding woodland and, once we have fully assessed the situation, we will swiftly take any appropriate action.”
A full statement has been published on our website at www.forestry.gov.uk/gallwasp, and will be updated as the situation evolves. The affected woodland is Farningham Woods, near Sevenoaks, Kent.

The benefits that all of London’s trees provide have been given a monetary value in the London i-Tree Eco Project report published yesterday. The quantity of these benefits – such as air quality improvement and carbon storage – is the result of the world’s largest survey of a city region involving hundreds of trained volunteers.
Most people appreciate the beauty of London’s trees but may not know, or tend to take for granted, the benefits that London’s urban forest provides for both people and nature. The i-Tree report, sponsored by Unilever, gives us a much better understanding of the structure and value of London’s urban forest. It is a method that is recognised worldwide and enables comparison with other cities. The information produced enables us to make better plans to manage London’s trees and highlights the need for continued tree planting to increase tree canopy cover over London.
The survey found that:
The report highlights that there are a wide range of tree species - not just native trees but trees from around the world - that are suited to London conditions. However, at a more local level there are vulnerable landscapes that are currently reliant on one or two tree species, such as some parts of central London dominated by the iconic London plane. In order to reduce the risk of large numbers of trees being lost within a short time, planting of a wider species range is needed.
The report calls for everyone to recognise and support the multiple benefits that trees provide for London and to make their own contribution to protecting and enhancing London’s tree cover. This will help ensure that London continues to be a green city for future generations by planting trees in gardens, supporting tree planting by others, supporting organisations that promote and protect London’s trees.
Environment Minister, Rory Stewart, said: “Our trees and forests have long been central to British identity. But we are beginning to understand with even more precision, just how important they are to our air quality, our health and our happiness. This is a fantastic initiative. And it sits very well alongside our drive to plant an additional 11 million trees in this parliament, and to support green spaces across the country.”
Charlotte Carroll, Unilever UK Sustainability and Communications Director, commented: “The findings of this report provide clear evidence of the importance of trees in the fight against climate change and of their value to our society in helping to deliver a more sustainable future. At Unilever we're working on this important issue through our brightFuture movement and with the UN Climate Conference, COP21 in progress, now is the time to engage in the importance of trees in our everyday lives.”
The Mayor of London, Boris Johnson said: “London is one of the greenest, leafiest cities on the planet and as this survey proves, our canopy does a ‘tree mendous’ job of lowering pollution, alleviating flood water and boosting our environment.”
Craig Harrison, Forestry Commission London Manager said: “The i-Tree report shows some of the ways in which London’s trees enhance our daily lives, and many of the trees we enjoy today are the legacy of past tree planting. But London’s trees face challenges such as development pressures, climate change and disease. With the expected increase in London’s population the need for more trees will increase - so we need to protect existing trees and plant new trees - to ensure London remains an enjoyable place to live, work and visit”
