Aspen sometimes called Eurasian aspen (Populus tremula) is one of two native poplar species to Britain; the other being black poplar (Populus nigra subsp. betulifolia). Recognised for its important ecological role as a host for numerous species and said to have more host-specific species than any other boreal tree.
A fast-growing elegant tree that can reach 25 m. The grey bark is covered in distinctive diamond shaped lenticels and on a windy day the tree can often be heard before seen with its distinctive rustling, shimmering leaves which provide its other common name, quaking aspen.
An important timber tree in parts of mainland Europe in Britain it mainly fills an ecological role in forest diversification or as a species for quick growing short rotation forestry. Increasing interest in planting suggests a need for further research into its potential as a productive forest species in Britain.
Aspen is a native tree and is categorised as a Secondary tree species. This is a species whose performance in trial plots has demonstrated promising silvicultural characteristics but gaps in our knowledge constrain wider use. Such species are being actively evaluated to increase our understanding and inform future deployment.
London plane is a hybrid between Oriental plane (Platanus orientalis) from southern Europe and American sycamore (Platanus occidentalis). Generally thought to have a garden origin in Oxford during the 17th century with some disputed evidence of an origin in Spain hence its other commonly used name the syn. Platanus x hispanica.
Very tolerant of atmospheric pollution and root compaction it is a popular street tree. With its mottled colourful bark, large size and stature it is instantly recognisable and an important part of London’s treescape, hence its common name. It is also widely planted in cities around the world with temperate climates for its ornamental and parkland value.
The young leaves and seed shed short hairs and can be an irritant when breathed in. This can exacerbate breathing issues particularly for people with asthma.
Although long cultivated and horticulturally well known there is little silvicultural knowledge on growing London plane as a productive forest tree in Britain. Current interest is the species may benefit from climate warming and its potential as an alternative to ash on some sites.
London plane is categorised as a Plot-stage species. These are species that have demonstrated some positive silvicultural characteristics at the Specimen-stage and are now subject to further testing in a limited number of trial plots.
The Forest Trapping Network is a rolling programme which will survey 100 forests for EU-survey list pests over five years. In each forest, plots of oak, pine, spruce, fir and mature mixed broadleaf are chosen to target different pest species. The FTN is currently in the first year of the Beta-phase (2022 - 2025), with the first full 5-year reporting period commencing in 2025 and finishing in 2030. The Alpha-phase of the project ran from 2020-2022, testing different lure and forest-type combinations.
Understanding the range of values held by farmers in relation to trees allows us to learn how, when, and where farmers may embrace having trees on their land. Explicit consideration of these values will better enable those working to design policies, incentives, tools, advice, or other communications to do so in ways which are more […]
What leads some farmers to dramatically increase the number of trees on their land? What role do social and cultural values play? And how do values and behaviour interact?
Increasing tree cover across England is a key priority for the UK government, driven by the benefits that trees and woodlands offer, such as climate change mitigation […]
