PEFC UK, with the assistance of a small working group are in the process of developing a standard for certification of ‘Trees outside Forests and specifically trees within an Urban environment'. This will be an appendix to the already endorsed national sustainable forest management scheme, which is the UK Woodland Assurance Standard (UKWAS).  The UKWAS has been adapted, with the grateful consent of the UKWAS Steering Group, to meet the requirements of the appendix in the PEFC International SFM standard (PEFC ST 1003: 2018) which covers ‘Trees outside Forests’. The consultation draft is out for consideration. It is hoped that once established, the standard will become an independently certified benchmark for councils and local authorities around the UK.


The consultation will last 60 days from 5th Jan 2021. After this period, the draft will be revised according to the feedback and comments received and submitted to the PEFC International for an Independent review and approval. https://www.pefc.co.uk/news_articles/pefc-trees-outside-forests-consultation
