Our 30th anniversary party / Xmas party was a huge success at the Dalston Eastern Curve garden as you can see from some of the party photos below. This community garden was a fantastic venue.
RE:LEAF Awards – Celebrating a leafier London
Londoners who can capture the immense value of London's trees and woodlands through poetry, prose, photography or posters are invited to enter this year’s RE:LEAF Awards. The ‘creative’ category joins five others for the fifth year of these prestigious awards (previously known as the London Tree and Woodland Awards.
RE:LEAF is an initiative supported by the Mayor of London , Boris Johnson, which aims to protect the capital's trees and woodlands and to encourage individual Londoners, businesses and organisations to plant more trees and increase and improve woodland management in the capital.
The awards recognise and celebrate the projects, and the individuals, groups and organisations, that are making significant contribution to RE:LEAF.
Craig Harrison, the Forestry Commission’s Manager for London said:
“London's trees and woodlands are loved by those who live and work in our capital city for making our streets more attractive and offering shelter from the sun as well as providing a long-term habitat for wildlife, reducing pollution and helping to mitigate against climate change”.
“These awards recognise those organisations, individuals and schools that help to improve London through their dedication to trees and woodlands.”
The categories this year are:
The deadline for receiving nominations is Friday 15th March 2013 and the Awards will be presented at an invited evening reception on 15th May in the London Living Room at the top of City Hall.
Details on the awards, categories and how/where to apply are available on the Forestry Commission London web site at http://www.forestry.gov.uk/releafawards

As part of supporting The Big Tree Plant Defra tasked the Forestry Commission to set up a Working Group of partners to highlight the main barriers and drivers to both planting new trees and retaining existing ones within urban areas. This recently released report highlights potential solutions through recommendations from the Working Group and is intended to provide a platform for discussion with the relevant sectors that are perceived to be contributing to the barriers listed. It is hoped that the report will encourage constructive dialogue and assist in challenging some of the more entrenched issues around the provision of trees in urban areas.
Members of the Working Group will be liasing with the various sectors and a final inclusive report will be published, with it is hoped real progress being made in overcoming the issues raised.
