2016 – New planting and publicly funded restocking

New planting New planting is the creation of new areas of woodland by planting trees on land that was not previously woodland. The statistics presented here also include new woodland that is created by natural colonisation of trees on land near existing woodland. Statistics on new planting are used to inform government policy and resource allocation, […]

Public perspectives of treescape creation, expansion, management and maintenance (a review)

This review aims to answer the question “what are the public perspectives of woodland creation, expansion, management and maintenance?” (where woodland is taken to refer to trees in any location and context). Using a combination of structured search strings and key word searches, the search process uncovered 81 relevant publications from 15 countries, published between 1996 and 2021 (inclusive). Given the policy ambitions for tree planting and woodland expansion across Great Britain, from the United Kingdom (UK), Welsh and Scottish Governments, the findings from this review are timely. The findings provide valuable evidence of possible public reactions to new planting, afforestation and changes to management, and identify gaps in the evidence where further work is required.

OPM Manual – 4. Biology and life cycle

Understanding the biology of oak processionary moth (OPM) can help you to manage it. The caterpillars are the larval stage of the insect’s life cycle. OPM gets part of its common and scientific names from the caterpillars’ distinctive habit of moving around in nose-to-tail processions on trees, and sometimes on the ground beneath host trees. They also frequently cluster […]
