Sycamore (Acer pseudoplatanus L.) is an invasive, non-native species in Great Britain and its management conservation areas controversial. Climate change adds further uncertainty to decision making. We investigated the role of history determining present-day abundance effects climatic variability on growth, photosynthesis phenology at Wytham Woods, a UK Environmental Change Network (ECN) monitoring site. Relatively few sycamore trees were found undisturbed ancient, semi-natural woodland...
European silver fir (Abies alba Mill.) was the first true to be introduced Britain in 1603. Despite early enthusiasm for species, it has not been widely planted and work on effects of woolly aphid (Adelges nordmannianae Eckstein) mid-twentieth century concluded that large scale use species could justified. This interpreted as a research challenge resulted establishment series provenance experiments being established between 1966 1970. Results from these after 46 years clearly show is...
Associational resistance theory predicts that insect herbivory decreases with increasing tree diversity in forest ecosystems. However, the generality of this effect and its underlying mechanisms are still debated, particularly since evidence has accumulated climate may influence direction strength relationship between herbivory.We quantified leaf chemical defences (phenolic compounds) silver birch Betula pendula pure mixed plots different species composition across 12 experiments climates....
Abstract Aspen ( Populus tremula L.) is a keystone species and model system for forest tree genomics. We present an updated resource comprising chromosome‐scale assembly, population genetics genomics data. Using the resource, we explore genetic basis of natural variation in leaf size shape, traits with complex architecture. generated genome assembly using long‐read sequencing, optical high‐density maps. conducted whole‐genome resequencing Umeå (UmAsp) collection. re‐sequencing data from...
There is growing interest in widening public participation research and practice environmental decision making an awareness of the importance framing questions that reflect needs policy practice. The Top Ten Questions for Forestry (T10Q) project was undertaken 2008 to investigate a process compiling prioritizing meaningful set questions, which were considered by participating stakeholders have high relevance, using collaborative bottom-up approach involving professionals from wide...
The main aim of the Glentress Trial Area has been to study transformation even-aged plantations a permanently irregular structure using group selection.The was established in 1952 when most were 20-30 years old.The 117-ha area divided into six Blocks and plan transform over 60-year period by felling regenerating groups totalling 2 ha each Block every 6 years.The objectives this paper are (1) examine design, implementation monitoring process (2) investigate if data collected can be used...
A series of species trials were set up to investigate the establishment and early growth (up 14 years old) 44 native non-native tree on a variety different site types in lowland Britain. On good quality afforestation sites, Platanus x hispanica (London plane) established grew more successfully than trees tested, may be an example that could theoretically anticipation future climate change. Experiments community woodland sites indicated range exotic species, such as X Cupressocyparis...
Abstract Aspen ( Populus tremula L.) is a widely distributed keystone species and model system for forest tree genomics, with extensive resources developed population genetics genomics. Here we present an updated resource comprising chromosome-scale assembly of P. genomics data integrated into the PlantGenIE.org web resource. We demonstrate use diverse types included to explore genetic basis natural variation in leaf size shape as examples traits complex architecture. genome generated using...
Abstract Non‐native plant pests and pathogens are increasing exponentially, causing extirpation of foundation species. The impact large‐scale declines in a single host on associated biodiversity is widely documented. However, the multiple loss whether these impacts multiplicative has not been assessed. Ecological theory suggests that systems with greater functional redundancy (alternative hosts) will be more resilient to sympatric hosts. We test this show its importance relation...
Summary There is much literature on natural regeneration which emphasizes the importance of good seed year, but few authors consider input in terms combination quantity (i.e. number seeds) plus quality percentage viable seeds). We have considered both aspects and also attempted to identify proportions vs poor seeds contributing via ‘ rain ’ cone drop . In addition studying input, we looked at effects vegetation control, ground preparation protection from small mammals seedling emergence...
In the UK, use of continuous cover forestry is increasing but effects such management on woodland ground flora has been little studied. this investigation, vascular plants in were observed before and after thinning to create plots with target basal areas 20, 15 10 m2 ha−1 within a semi-natural Fraxinus excelsior woodland: treatments exclude deer control bramble (Rubus fruticosus) also applied. Although 45 new species appeared only 26 remained 5 years thinning; their was often 1–2%. Before 38...
Natural regeneration can reduce costs compared with replanting. However, its use requires knowledge about how either active or passive management will affect the balance between quality and quantity in timber supply. This study aimed to quantify effects of respacing on volume recovery wood properties. Two British forest experiments using Picea sitchensis various distances an un-respaced control were assessed 21–22 years after treatments applied. Tree dimensions measured used slenderness,...
Extensive damage to and mortality of understorey seedlings during overstorey thinning could prevent the use natural regeneration as a method restocking. Experiments carried out on three upland conifer sites in Britain assessed short-term impact operations survival advance different heights. At two dominated by Sitka spruce, number small-sized (<50 cm) medium-sized (50–200 lost harvesting was significantly higher than large (>200 which tended be damaged rather lost. Scots pine/Japanese larch...
Rhododendron ponticum (L.) is a highly invasive and competitive weed on many forest sites in Britain can act as host for the pathogens Phytophthora ramorum (Werres) P. kernoviae (Brasier). Control of rhododendron be difficult due part to its thick waxy leaf surfaces, which discourage absorption foliar-applied herbicides. The adjuvant Mixture B has been used years improve efficacy, rainfastness glyphosate control, but formulation changed, new product, 'Mixture NF', not independently tested....
A UK field trial compared the efficacy of a range synthetic herbicides and fungal biocontrol agent Chondrostereum purpureum (Pers.) Pouzar at preventing resprouting Rhododendron ponticum L. following cutting, hence countering infection with Phytophthora ramorum Werres or P. kernoviae Brasier. Treatments were applied to cut rhododendron stumps in summer winter, regrowth was evaluated 25 months after application. All chemical herbicide treatments significantly reduced regrowth, would therefore...
Understanding how we can increase the resilience of forest systems to future extreme drought events is increasingly important as these become more frequent and intense. Diversifying production forests using intimate mixtures trees with complementary functional traits considered one promising silvicultural approach that may resilience. However, direction magnitude response mixed-species stands relative monospecific same species vary identity, abundance levels competition in a focal tree's...
In direct-seeded woodlands and nursery seed-beds, weeds can rapidly invade newly sown areas, leading to death or suppression of tree seedlings. Hand weeding is usually expensive, the safe use broad-spectrum contact herbicides seldom possible. Hence in work reported here, tolerance young seedlings potentially more selective, post-emergence clopyralid, cycloxydim metazachlor, was tested. Seedlings Fraxinus excelsior L. (ash) with two four expanded true leaves (2–4 ETL), Fagus sylvatica (beech)...
Abstract There is a strong policy move in Britain to improve forest resilience climate change by increasing stand structural and species diversity. Although currently little used Britain, the technique of underplanting allows regeneration diversification stands while avoiding some disadvantages clearfelling. Two experiments were examined: (1) growth survival five underplanted conifer differing shade tolerance shelterwood (2) compared performance open-grown Douglas-fir seedlings on restocking...
