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.
The Forestry Commission Awards webpage has now been updated with details of the 2015 awards and we are now accepting nominations www.forestry.gov.uk/london-awards.
3 new categories have been added this year:
The deadline for nominations is 12th March 2015 and the nomination form is available on the webpage. There are also PDF summaries of the 2013 and 2014 awards on the webpage with links to the winners case studies, so we don’t lose this valuable legacy information.
Chalara has been found in both planted young ash trees and in wider environment ash trees at sites near Rainham, Havering and Orpington, Bromley. These sites are all on the outskirts of London and adjacent to known chalara sites outside London, so the news does not come as a surprise and is in line with expected spread of chalara. The FCChalara website has a map showing the known distribution of Chalara including these latest findings; please note the map is based on positive results in 10km squares rather than specific sites.
Key messages are:
Please find below a link to the LTOA Surface materials around trees in hard landscapes Draft Document, for consultation. We are seeking views and opinions about this document from our Membership and from specialists in other industries, such as highway engineers and urban designers. Comments should be sent to Becky Porter, LTOA Executive Officer, before Friday 30th January 2015. Feedback will then be collated and discussed by the Surface materials around trees in hard landscapes Working Party and agreed changes will be made accordingly.
Please note that this consultation draft does not feature any images; this is a review of content rather than presentation and appropriate images, tables etc. will be incorporated into the final document.
We look forward to receiving your responses.
John Parker - Chair of LTOA Surface materials around trees working party
A key objective of the LTOA is to 'Improve the health, increase the extent and guarantee the resilience of London’s tree canopy'
Despite the many positive changes, and increases in awareness, understanding and practice in recent years in relation to our natural heritage and care for our environment, we are beset everyday by greater threats to the ecosystem we inhabit.
The LTOA is responsible for much of London’s tree population, a fundamental part of the environment, and the keystone species that support humans and wildlife and interconnect the entire city’s natural and physical processes, its water, soil and the very air we breathe.
We are increasingly informed about the importance of our tree canopy for air conditioning, and managing water, soil and drainage systems, the effectiveness of which is essential to the quality of urban living. The increasing risks of new pests and diseases to London’s trees, if unchecked, threaten the canopy and skyline as we know it today.
The prospect of such declines and losses places a clear responsibility on government, municipal managers, LTOA members and the public to invest in protecting our trees if we are to secure and enhance their contribution and continuity for the benefit of city life.
This position statement reflects current concern about a number of significant pest and diseases threatening the health of London’s trees, including:
