The HIRP Conference intends to provide an industry update on the current Hylobius control options available to forest managers, an overview of the research and trials currently underway and those planned which look at alternatives to the current main control method (of acetamiprid applications), discuss the FSC pesticide policy and the requirements outlined in the acetamiprid ESRA, as well as introducing the SFT Hylobius fund.
It is anticipated that the event will highlight the constraints which current Hylobius control methods pose to the sector and encourage funding and support into finding alternative controls, particularly through contributions to the SFT Hylobius fund.
The group aims to run the event at the Birnam Arts Centre in Perthshire in April 2022.
This Bursary project aims to use Raman spectroscopy to deepen the understanding of fungal infections within trees, specificall ash die back and oak powdery mildew. This will involve examining the leaf wax and cuticle layers of leaves from the respective trees and using Raman spectroscopy to identify any microscopic chemical changes. This knowledge will be used to develop a sensor to allow early identification of ash dieback and oak powdery mildew in the field.
The project will be building on current and past research into leaf Raman spectroscopy by developing a detailed model of fungal infection and resistance.
The high cost of returning to a site and removing and disposing of used plastic tree shelters at the end of their useful life has meant that in many cases they are simply left to gradually photodegrade. Not only is this unsightly, but it forms a source of plastic micro pollution in the developing forest. For this reason, a number of manufacturers have been striving in recent years to develop tree shelters, often made from materials other than conventional plastics, that could in theory be left in situ on site without a need for them to be removed and recycled.
This project aims to independently verify the durability and efficacy of a range of these alternative products. Depending on results, the intention would be to publish at least one paper in a reputable peer reviewed scientific journal to publicise our findings. In addition, a dedicated webpage will be set up, and at least one trade journal article will be produced to publicise the scientific paper, and to give clear, practical recommendations for managers.
That bats use tree roosts is well known, but what appears to be under-appreciated is that bats are often found in ‘roosts’ in very small ‘weedy’ trees that foresters may consider unworthy of investigation. This clearly has huge implications for forestry practice. This award will allow us to analyse the Bat Tree Habitat Key (BTHK) data (an open source database contributed to by bat ecologists across the country) to describe the types of trees (species, size, characteristics) and tree features (entrance size, tree position) used by bats as roosts. An important part of this project will be to publish and publicise our findings, to provide an evidence base for related practice/policy recommendations, and to raise awareness of the issue.
The project will use a selection of fieldwork and laboratory techniques to improve understanding of how the biological communities of upland soils cycle nutrients and remain productive, possibly illustrating the suitability of upland soil types for forestry applications. Genetic material sourced from soils across the Scottish Highlands will be gathered and sequenced using next generation sequencing technologies, providing novel insights into the biological communities beneath our feet. A series of experiments will then be conducted to determine exactly how these communities retain nutrients within forest ecosystems subject to high rainfall. The results of the project promise to give exciting insights into how the soils of production and conservation forestry can be managed for optimum productivity, either improving yields or developing the ecosystems upon which Scottish wildlife depend.
This is a partnership initiative between Confor and the Scottish Council for Development and Industry (SCDI) to expose young people to the range of opportunities that exist within the forestry and timber technologies sector via STEM club activity in schools. The pilot is planned to last 3 years in the first instance and will target S1-S3 pupils in the Highland Council area on two programmes - Climate Smarter and Highland Celebration of Engineering starting in the Academic Year 2021/2022. Climate Smarter involves pupils engaging in a project around future schools and a resource pack on use of homegrown timber in buildings will be integrated into this successful SCDI programme. The partnership and initial engagement with schools will focus around an event linked to COP26.
SCDI have access to over 1600 primary and secondary schools across Scotland via their YOung Engineers and Science Clubs and they operate a number of initiatives and competitions to excite and engage young people of all ages.
This research project supported by the Bursary Fund wil evaluate the use of entomological Integrated Pest Management in forestry, using case studies to identify the drivers and barriers to successful implementation, and form consluding recommendations to enhance forestry practice. The case studies will focus on the great spruce bark beetle (Dendroctonus micans) and the large pine weevil (Hylobius abietis).
The trial objective is to test different provenances of S.torminalis for survival, growth and stem quality in order to provide recommendations for silvicultural practice. Scottish Forestry Trust’s support for the trial will enable the creation of a survey protocol that will then guide measurements and monitoring to be carried out at regular intervals during the first phase of this project, with survival and early growth analysed after one, two and three years. By the end of the first phase, there will be clear outcomes emerging as to the best performing provenances out of nine selected from the UK and Europe. These results will be disseminated to industry bodies and publications directly and online for wider consumption, representing the only provenance trial for Wild Service Tree ever to have been undertaken in Britain, which will help raise the profile and potential of this under-used but potentially remunerative hardwood.
Protection of genetic diversity within tree species (genetic resources) is vital to ensure their long-term capability to adapt to change. Juniper (Juniperus communis) is under severe pressure in the UK due to its highly reduced and fragmented population size, low regeneration rates, climate change and the arrival of a novel pathogen, Phytophthora austrocedri.
This project will help to support a PhD studentship to address fundamental gaps in our understanding of levels and management of genetic diversity in Juniper in the UK, and to translate that into conservation measures via the EUFORGEN dynamic conservation framework.
The project will aim to:
1. Characterise genetic diversity in natural populations
2. Quantify adaptive genetic variation in experimental populations
3. Translate research findings into guidance for management and restoration
The ‘Boom and Bust’ (masting) patterns of acorn production have significant economic impacts: it results in an unreliable annual supply of well-adapted and high-quality acorns to forestry, while there is a high demand every year. Shortages are problematic since recalcitrant seeds cannot easily be stored, imported seeds may be of an unsuitable provenance and pose biosecurity risks. The aim of this doctoral research is to investigate the highly variable acorn production by native oak in the UK, so as to inform seed supply industry and seed stand management.
It will aim to answer the questions:
1. What is the (historic pattern) of masting and mean acorn production in the UK at the seed zone level?
2. When, and at what phenological stage is seed development currently halted (i.e. what are the premature abscission rates at each phenological stage)?
Whilst current approaches to the use of wood are highly optimised and integrated, novel technologies can be developed that further improve the efficiency of use of all the possible product streams. The current use of LIGNIN derived from wood is to burn it and this represents an inefficient use of this potentially valuable resource. It is desirable to convert wood into a set of product streams that can be used for several different applications.
One of these streams should be a high quality Lignin, whilst other streams should contain cellulose and hemicellulose-derived sugars. Current methods of isolating high quality lignin from (i) Sitka spruce and (ii) mixtures of soft and hardwoods can be improved. After isolation from the wood, it will be advantageous to purify (fractionate) the Lignin before attempts are made to convert it to feedstock chemicals. The proposed programme of work builds on these assumptions.
Eighty-percent of the UK population live in towns and cities. Urban trees provide numerous benefits to urban society, including air pollution removal, building energy conservation, urban climate regulation, and access to nature. Urban tree managers and government agencies are interested in assessing the magnitude and socially equitable distribution of urban tree benefit delivery, and building resilience under a changing climate. However, a national picture of urban forest cover, composition and quality does not exist. At the city scale, such information is occasionally available through local uptake of “i-Tree” tools.
This project aims to critically examine urban forest sampling protocols with a view to optimising i-Tree Eco surveying. By clarifying the surveying effort required and maximising output accuracy the project aims to increase the opportunity for cities to gain the inventory data required for evidence-based policy creation, and development of management strategies that maximise delivery of tree benefits to urban society.
Habitat restoration involving woody species is critical for halting and reversing biodiversity loss and mitigating climate change impacts. However forests are complex ecological systems and present major challenges for successful restoration sustainable management. Innovative conservation practices are needed to achieve effective restoration across upland landscapes and reduce risks of habitat fragmentation in the face of changes in climate and grazing regimes in Britain post-2020.
This research will investigate how exploiting microsite factors, mycorrhizal associations and natural regeneration potential can be used to improve the outcomes of montane scrub restoration projects in Britain. It intends to aid the development of conservation management techniques which will create healthy and sustainable upland tree populations, thereby facilitating the long-term resilience of this biodiverse habitat and the expansion of the treeline ecotone.
This study will quantify baseline levels and changes in genetic diversity during the course of the UK's Sitka spruce genetic improvement programme. Using microsatellite markers, the study will first determine the quantitative measures of genetic diversity in native QCI populations and unimproved commercial stands of Sitka spruce in the UK to estimate any reduction in genetic diversity that occured in the introduction process.
The project will then go on to measure how this introduced genetic diversityhas changed as a consequence of the different tree improvement strategies, either seed orchards or vegetative propogation, employed to produce stock.
The study will provide important information to help guide the future development of the Sitka spruce improvement programme.
This research will integrate new and existing tree-ring data on Picea and Pinus species to deliver a predictive understanding of the change in tree risk, resistance, recovery and resilience to drought, in the dominant commercial conifer species in the UK. Industry outputs will include dissemination via forest industry forums, maps, and probabilistic risk and vulnerability functions which will be integrated into the decision support systems (including the online Forest Research DSS system) available and widely used by UK forest managers. Academic outputs will include scientific articles and conference presentations.
Woodlands planted on arable land and improved pasture fail to develop woodland plant communities and remain dominated by grass and agricultural weeds; even in old woods. This severely limits their biodiversity value, including impacts on some invertebrate populations; and reduces the amenity and recreational appeal of the woods.
This can be addressed via careful introductions of missing woodland plant species aimed at simply establishing small viable populations that can colonise the wood over time. There are a few trials of woodland plant introductions in Scotland and England; but none have used this approach and are suitable for long term monitoring and research.
a) Establish long term demonstration sites to test the feasibility of introductions, provide evidence of outcomes, refine methodology and seek cost-effective approaches.
b) Arrange training events focused on good conservation management of lowland planted woods.
1) a paper(s) describing improved management practices;
2) enhanced understanding and professional capacity amongst managers;
3) a long term research resource;
4) a student dissertation.
