A demo-genetic model shows how silviculture reduces natural density-dependent selection in tree populations

We developed an individual-based demo-genetic forest model, LUBERON2, to investigate the combined effects of genetic diversity, management scenarios and disturbance regimes on stand performance and evolution.

In many forests, fisheries and other semi-natural ecosystems, human interventions interfere with natural evolutionary processes. Previous studies provided evidence of direct or indirect anthropogenic selection in such systems. Here, we simulated random tree thinning scenarios, i.e. without anthropogenic selection.

We show that the evolutionary rates predicted by the model fit in the range of observed values in wild plant and animal populations. The primary impact of random tree thinning is to partially substitute anthropogenic selection for natural selection: (i) by changing stand structure throughout the forestry cycle, the forester reduces the intensity of natural density-dependent selection processes; (ii) the composition of the reproducing population results from forester’s choice and not only from natural selection. Thus, even presumed “neutral” population management still has non-neutral evolutionary consequences.

Highlights

  • Several generations of improved forest trees have been deployed over the last decades
  • Genetic improvement in the studied countries is based on a structurally sound system of innovation
  • Forest tree breeding suffers from both market and systemic failures.
  • Private investment in forest tree breeding occurs if the industry is vertically integrated
  • Public funding for and direct provision of breeding programmes is paramount

Close-to-nature forestry and intensive forestry – Two response patterns of forestry professionals towards climate change adaptation

A new publication in Forest Policy and Economics analyses how forestry professionals in 9 European countries perceive climate change effects and adaptation strategies. The publication is based on the work carried out in B4EST’s WP5.

  • We observe a North-South gradient in climate change perceptions, with Northern Europe perceiving effects as less severe.
  • We find particularly negative perceptions in Germany likely influenced by the extreme summer drought of 2018.
  • We distinguish two main climate change adaptation approaches: close-to-nature forestry and intensive forestry.
  • These 2 adaptation approaches hold significantly different promise for the provision of multiple forest ecosystem services.

Transformative changes in tree breeding for resilient forest restoration

A new publication in Frontiers in Forests and Global Change reviews the work of the B4EST project to show the opportunities from transformative tree breeding in forest restoration schemes .

Ray D, Berlin M, Alia R, Sanchez L, Hynynen J, González-Martinez S and Bastien C (2022) Transformative changes in tree breeding for resilient forest restoration. Front. For. Glob. Change 5:1005761.

https://doi.org/10.3389/ffgc.2022.1005761

Deciding how to establish woodland in forest restoration is not straightforward as different outcomes may be obtained from different establishment approaches, each with cost implications and degree of success limitations attached. Planning restoration requires knowledge of site conditions, including how sites are likely to respond under climate change. For objectives of production and high timber quality it is likely that ground preparation will be used, and planting with forest reproductive material (FRM) of known traits, such as: high survival and growth in establishment, drought tolerance adequate for climate projections, good resistance to pests and pathogens. For objectives associated with biodiversity, carbon sequestration, water supply protection, soil protection, natural regeneration could be a less costly solution with a limited amount of assisted translocation of selected FRM to improve resilience. If objectives are for rewilding forest areas, a degree of natural colonisation perhaps with translocation of some FRM could be a solution. Ignoring site conditions and suitability of available sources of FRM for forest restoration is likely to provide unexpected results with a mix of open ground, scrub and scattered trees resulting from climate, herbivore, and browsing impacts.

The recent B4EST EU Horizon 2020 project examined progress in novel rapid approaches for testing the quality of FRM from existing genetic trials. Here we review the work of B4EST to show the opportunities from transformative tree breeding in forest restoration schemes, including: new climate projection ensembles at high temporal and spatial resolution to develop norms of reaction and transfer models with genetic components; multi-environment genotype-phenotype associations and multi-locus genotype-environment associations in identifying drivers of local adaptation; techniques for genomic selection using single nucleotide polymorphism (SNP) arrays to derive functional traits from polygenic associations; work on seed orchard site and climate specific FRM and zones for deployment; and work on some of the forest ecosystem service benefits derived at a landscape scale. We conclude that tree-breeding will provide robust forest restoration for planting, and rewilding (assisted natural regeneration), and if not “ignoring” but instead assisting natural colonisation processes – tree breeding may improve long-term forest resilience under environmental change.

B4EST policy brief published

The new B4EST policy brief looks at how forest tree breeding can contribute to EU policies, and sets out how forest tree breeding deployment and forest management can be a key tool for reaching the EU Green Deal goals.

The policy brief explores what challenges lie ahead for the future, and makes recommendations as to what policy changes are needed.

This policy brief produced by the B4EST project highlights the importance of forest tree breeding to support the EU Forest Strategy, Green Deal goals and the EU Biodiversity Strategy. The technique, methods and tools of tree breeding are imported from agriculture, and, in forestry, have been actively developed and adapted during the last century. Forest tree breeding has a high potential not only to contribute to mitigating climate change (for example enabling the selection of faster-growing trees), but also assists the adaptation of European forests to climate change. This serves the bioeconomy, ensuring forests continue to provide a wide range of products and services, and also facilitates landscape restoration after major ecological disasters.

Climate change can increase forest vulnerability to damage and disease, reduce forest health and productivity, and cause economic losses. B4EST’s goal is to increase jointly forest survival, health, resilience and productivity under these circumstances, while maintaining genetic diversity and key ecological functions, and fostering a competitive EU bio-based economy.

•What is forest tree breeding, where and how is it used?
•Why is it important in a global change context?
•How does it support EU Green Deal, forest strategy and biodiversity policies?
•What policies regulate its use?
•What challenges lie ahead?
•What policy changes are needed?

B4EST Nordic policy brief published

The forest sector is of great importance for the economy of the Nordic countries as well as for the supply of wood resources in the EU. Almost 30% of the European forest area and nearly 20% of the growing stock of European forests is in Finland, Sweden, and Norway (State of Europe’s Forests, 2015). Socioeconomic importance of forest is even more significant in Finland and in Sweden. These two countries produce almost 30% of sawn goods, and 60% of pulp for paper and paperboard in the EU and generates over 110 000 direct jobs.

The B4EST Nordic policy brief focuses on specific challenges for the Nordic region, and provides recommendations for FRM management and transnational cooperation.

Using forest genetic resources for climate change mitigation and adaptation

Watch the keynote presentation on forest genetic resources given by Dr Tongli Wang (Associate professor at the University of British Columbia, Canada) on 20 June 2022.

Climate change is causing a mismatch between the climate that trees have adapted to in the past and the climate that the trees will face in the future. Natural migration and evolution may take too long to achieve new local adaptation. Using the available genetic resources created by nature and tree improvement programs will probably be the most effective way to mitigate and adapt to climate change. Nature has created a large number of tree species for different climate conditions and among-population variation along climate gradients within species for local adaptation. Improved genetic materials have been produced through breeding for various objectives, including fast growth and resistance to pests, diseases, and harsh environments. However, challenges remain in making effective use of these genetic resources to fight against climate change.

Dr Wang looks at:

1) using climate niche models to assess the impact of climate change and to assist species in matching their suitable climate;

2) using transfer and response functions to understand the genetic and physiological responses of populations to climate change; and

3) the use of genomic information for delineation of seed and breeding zones.

7th IUFRO Workshop on Genetics of Tree-Parasite Interactions in Forestry

Understanding forest tree-antagonistic interactions in a
changing world

September 20-24, Pontevedra, Spain

More information

Managed and natural forests provide essential ecosystem services worldwide. Due to the free of movement of people and goods across biogeographical zones, tree species are increasingly challenged by emergent invasive biotic threats. We can see large range expansions of pests and diseases, as well as sudden shifts to naïve host species. Moreover, climate change is also increasing abiotic tree stresses, which synergistically interact with tree resistance leading to negative effects on tree survival and forest resilience.

Although forest tree species are known to harbour high levels of genetic variation, most remain fairly unstudied, particularly in traits related to host tolerance and resistance to biotic and abiotic stressors. To understand such variations, within the framework of the genetics of tree-antagonist interactions, is necessary to forecast the survival and prevalence of forest populations in a changing environment. This knowledge can also be exploited in breeding programs aiming to improve forest health.

The scientific community is pushing for an urgent multidisciplinary and coordinated effort to solve these challenges, making use of current and new knowledge, strategies and technologies. Geneticists, evolutionary biologists, ecologists, phytopathologists, entomologists, plant physiologists, breeders and managers are all involved in this challenge. This workshop will provide the ideal forum for updating knowledge, evidences, solutions and failures between scientific, academic and practical approaches. It is also an opportunity to enhance the dialogue of long experienced expertise with the new generations of scientists, which will provide creative and new solutions in the near future.

EVOLTREE Online Seminar Series on Polygenic adaptation

EVOLTREE has launched a series of online seminars about polygenic adaptation in trees and other organisms. The events will be streamed on YouTube and recorded.

Variation in complex phenotypic traits, like growth, is known to be driven by many genes. For example, it has been shown that the height of humans is associated with thousands of regions in the genome. Approaches for detecting polygenic signals from genomic data, however, are still scarce and rarely applied. This seminar series aims to promote an exchange of knowledge among scientists working on polygenic adaptation in disparate organisms with the objective of facilitating development and wider uptake of the latest approaches.

Programme

28 October 2020, 16:30-18.00 CET
Jonathan Pritchard: ‘Architecture and adaptation of human complex traits’

4 November 2020, 16:30-18.00 CET

New COST Action in epigenetics/epigenomics

A new COST Action relevant to the B4EST community, EPI-CATCH “EPIgenetic mechanisms of Crop Adaptation To Climate cHange” has begun.

Its objective is to define, develop, generate and share new breaking knowledge and methodologies for the investigation of epigenetic mechanisms modulating plant adaptation to environmental stresses driven by climate change. So far, no international network has been created with the aim of standardizing methodology in plant epigenetics/epigenomics and better integrate these data with other “omic” approaches. EPI-CATCH will create a pan-European framework for networking in this under-investigated research field.

More information can be found on their website https://www.cost.eu/cost-action/epigenetic-mechanisms-of-crop-adaptation-to-climate-change

Briefly: EPI-CATCH has been designed to address the following issues:

  1. the scarce research investment in developing methods and infrastructure for plant epigenetics/epigenomics,
  2. the heterogenous and complex nature of epigenetic mechanisms,
  3. the significant impact derived by new epigenetic discoveries.

EPI-CATCH has 3 main challenges in epigenetics/epigenomics: 1) improving lab methodology. 2) improving in silico data analysis and 3) better integration of epigenomic data with other “omic” data.

For each country, persons interested in the project could contact the member of the Management Committee representing their country – you can find the full list here: https://www.cost.eu/cost-action/epigenetic-mechanisms-of-crop-adaptation-to-climate-change/#tabs|Name:management-committee

Planter’s guide – new tool for choosing Scots pine plant material in Sweden and Finland

A new web-based tool developed with support from the B4EST project provides recommendations of the best available Scots pine seedlings from seed orchards in Sweden and Finland. It allows the user to select a planting site and compare plant material from both countries.

The tool builds on a new model framework developed in spring 2019, which allows Swedish and Finnish seed orchard crops to be ranked and compared on the same scale in either of the countries. This has now been implemented in a freely available web-based decision support tool (Planter’s Guide) which covers both countries in each language, and also as an English version.

The user can select an arbitrary planting site, either by clicking on a map or by providing coordinates. The tool then produces a list of seed orchards ranked according to a performance index, by growth or by survival. The deployment recommendations are climate adapted: the performance index is based on survival ability in the current climate, but simultaneously taking advantage of the improved growth conditions in the future climate.

Additional information about each seed orchard (e.g. ownership, clonal origin, establishment year, size) is available by selecting and clicking on it in the list. A map of the suitable deployment area for each seed orchard is shown, and the deployment maps for different seed orchards can be compared.

Survey results show positive perceptions of adaptive tree breeding

A European survey carried out by the B4EST project shows that improved forest reproductive materials are perceived positively by the forest sector, and are considered important in forest regeneration and afforestation to adapt to climate change.

The survey wanted to understand the experiences and expectations of different groups in the forest sector towards adaptive tree breeding, and the usage and uptake of improved forest reproductive material (FRM). FRM refers to all parts of a tree that can be used for reproduction, for example fruits, seeds and cones. Improved FRM which result from selection on a combination of adaptive and production performances can provide specific benefits, for example better resilience to climate conditions, pests and diseases.

The survey received 565 responses from nine European countries (Finland, France, Germany, Italy, Norway, Portugal, Spain, Sweden and the United Kingdom). The online survey was open to all stakeholders of the forest-based bioeconomy, and received the highest number of responses from public administrators as well as public and private forest managers. Eight species were investigated – six native (Norway spruce, Scots pine, maritime pine, poplar, common ash, stone pine) and two non-native (Douglas-fir, Eucalyptus).

The results show that negative effects of climate change are increasingly expected by 2050, with regional difference between Scandinavia and Southern Europe. There is some confidence by the European forest sector that future climatic changes will be manageable, and that improved forest reproductive material will be an important management strategy to adapt to climate change. Respondents said their three most important forest management strategies to adapt to climate change will be:

  • Diversification of tree species
  • Artificial regeneration with improved forest reproductive material combined with revision of guidelines towards optimal adaptation to future climate
  • Enrichment of natural regeneration with forest reproductive material better adapted to future climate changes

To successfully adapt to climate change, the use and importance of improved forest reproductive material is expected to increase and at the same time, more research is needed to find solutions to the biggest threats like droughts, windstorms and pests. This may indicate that breeding programs for a larger number of species are required, to reach an expected level of diversification.

Training workshop on “Concepts and tools for optimum selection in forest tree breeding”

28-30 October 2019, HÖÖR, Sweden
More information

Organised by the GENTREE project.
Participants: forest managers and practitioners, forest breeders
Deadline for application: 15 June 2019

Tree breeders must often consider conservation of genetic diversity, while at the same time they attempt to maximize genetic response to selection. This challenge is common to management of populations for both gene conservation and elite breeding, as well as to assembly of deployment populations, such as seed orchards and mixtures of selected clones. GenTree has developed several tools and advanced methods for addressing this challenge.

The purpose of this course is to provide participants with the background and user-skills necessary to apply these tools correctly in the context of applied forest tree breeding programs. Different tools for “optimum selection” will be presented, such as “OPSEL”, which uses state-of-the-art mathematical approaches to optimize selection with a specified constraint on gene diversity. Other approaches include managing genetic diversity at the genomic level to guarantee short- and long-term genetic gains or levels of fitness, notably under genomic-evaluation scenarios.

After “optimizing” genetic contributions to a selected population, the practitioner still faces the daunting task of preparing mating plans that respect these contributions, while avoiding excessive relatedness between parents. A generalized tool “XDesign” makes this task straightforward, allowing the user to specify a threshold on the maximum acceptable coancestry between mates.

The training will show the concepts and functioning of several strategies to account explicitly for diversity across the genome of candidates during selection and mating steps in the context of breeding and conservation programs. Breeding strategy evaluation will be addressed with R-scripts and the simulation package “POPSIM’.

1st B4EST annual meeting

B4EST partners gathered in Edinburgh from 21-23 May for the first Annual Meeting. The meeting was a chance for an update on the progress of the project, and to work together with colleagues on the project’s objectives: proposing options to manage and help forests adapt to climate change.

B4EST works with eight of the most economically, ecologically and socially important tree species in Europe, and the focus for this meeting was Scots pine.

Guest speaker Richard Ennos from the University of Edinburgh looked at how Dothistroma septosporum was affecting pine trees in Scotland and the pathogen’s evolutionary potential. The pathogen affects 82 species of pine, and spreads by spores to infect the tree crown, causing growth reduction. Currently there are a number of epidemics worldwide, in Europe, North America and New Zealand, and it was first recorded on native Scots pine in the UK in 2010.

There have been previous breeding programmes for resistance in New Zealand, which has only a single asexually reproducing Dothistroma genotype. But the UK situation is different – three genetically distinct clusters of Dothistroma septosporum have been found in Scotland, confirmed by genome resequencing. Of interest to B4EST, is how is this likely to affect breeding for durable resistance. The resequencing showed the genetic diversity, sexual reproduction within races and hybridisation between races of D. septosporum in the UK, meaning that there is high evolutionary potential, much greater than in New Zealand. Breeding for durable resistance is therefore more difficult, because you are breeding against something which is changing. Richard concluded there is a need to rethink traditional tree breeding programmes to integrate continuous natural selection driven by changing composition of evolving pest and pathogen populations.

Matti Happanen from LUKE gave an overview of the current panorama of Scots pine breeding and the potential uses of genomic information. There are some constraints – an economic rotation of 70-100 years, difficult clonal propagation, late sexual maturity and fairly small seed yield.  Accurate genomic relationships are the most useful new information for operational breeders, while possible additional gains will arise from higher accuracy and selection intensity, rather than from faster breeding. Genotyping costs are still far too high for largescale operational breeding applications, but further reduction of the costs will open new ways to implement genomics in tree breeding.

Take our survey on adaptive tree breeding!

The B4EST project is launching a European survey on adaptive tree breeding, open to people working in the forest sector such as forest managers and owners, tree breeders, and representatives of forest associations and industry.

B4EST is an EU Horizon 2020 project which has a focus on fostering productive, sustainable and resilient forests under climate change. The survey aims to identify a realistic picture of the experiences and expectations of different groups in the forest sector towards adaptive tree breeding and the usage and uptake of improved forest reproductive material (FRM). FRM is used in regeneration and afforestation, and refers to all parts of a tree that can be used for reproduction, for example fruits, seeds and cones. Improved FRM provides specific benefits, for example better resilience to climate conditions, pests and diseases.

By taking the survey, you will have the opportunity to influence future FRM developments, and inform policy makers.

It takes about 15 minutes to answer the questions, and you can choose whether to answer anonymously or leave contact details if you wish to receive an executive summary of the key findings.

The deadline for answering the survey is 10 March 2019.

Postdoctoral researcher vacancy

Postdoctoral researcher, Tandem Forest Value project FutureGenes
Oulu/Umeå

We are searching for a post doc researcher to work on Tandem Forest Value Project FutureGenes. It is a two-year position starting in December, 2018.

Tandem Forest Values is a bilateral (Finland-Sweden) research program within forestry and the forest products industry. FutureGenes project combines four teams: National Resources Institute Finland, Luke (prof. Katri Kärkkäinen) SLU (Prof. Harry Wu) UOulu (Dr. Tanja Pyhäjärvi) and Skogforsk (Dr. Mats Berlin) to study genetics of adaptation to climate and possibilities to mitigate the effects of climate change to forests via breeding and optimal seed deployment. In the project, we will analyse data on Scots pine and Norway spruce obtained in national projects on local adaptation and genomic selection, and in an ongoing H2020 project B4EST (Adaptive tree breeding strategies and tools for forest production systems resilient to climate change and natural disturbances).

We are searching for a post doc researcher to work with us e.g. in analyses of genetic variation, differentiation and genomic prediction (e.g., quantitative genetic and sequence variation analyses, genomic selection methods), and in defining optimal deployment models for future climates.
