WP1 – Productive forest management for bioenergy

 
WP1 should develop silvicultural models with 25-80% increased productivity relative to current levels and develop recommendations on trade-offs between GHG displacement and sequestration. With due attention to Nordic energy and sustainability strategies and to the diversity of conditions in the Nordic countries, we analyze production potentials of existing and future Nordic forests with respect to species selection and management intensity as well as the increased growth potential that climate change offers.

Activities and deliverables

1. Review of suitable tree species for increased biomass production (T1-P1)
Natural regeneration, direct seeding and planted material. Metadata analyses (based on literature) and data from own field experiments.
Deadline: Dec 2013. Lead: Per-Magnus Ekö.

2. Estimation of Nordic land areas available for increased future biomass production as well as estimation of current biomass production (T1-P2)
Establish a base of information for evaluation of the potential increase in biomass production depending on species and management intensity for Nordic conditions. EFINORD is going to publish a paper/report titled Facts and Figures of the EFINORD Forest Sector. We will follow this process and see if this work is useful for our task.
Deadline: Dec 2012. Lead: Lars Rytter.

3a. Review of breeding potential for increased biomass production of fast growing tree species 2010-2050 (T1-P3)
Deadline: Mar 2014. Lead: Lars-Göran Stener.

3b. New assessments and selection of poplar and hybrid aspen clones
(T1-P3)
First evaluation of new Swedish clone test.
Deadline: Aug 2015. Lead: Lars-Göran Stener.

4a. Potential increase of biomass production by fertilization 2010-2050
(T2-P4)
Deadline: Dec 2012. Lead: Johan Bergh.

4b. Balancing the trade-off between increased growth, nutrient leaching and GHG balances in fertilized stands of fast-growing tree species (T2-P5)
Deadline: Aug 2015. Lead: Inge Stupak.

5. Highly productive silvicultural systems (T3-P6)
Reviews on establishment, growth, management, nutrients, technology, economy, health and adaptation. Activities during the whole project period. Establishment of Populus on agriculture and forest land. 
Deadline: Aug. 2015. Lead: PhD(RM) (2 papers).

Early growth and management possibilities of second generation hybrid aspen.
Deadline: Aug. 2015. Lead: PhD(RM) (1 paper).

Modified silviculture models and tree species mixtures for biomass production. New combinations of planting, direct seeding and natural regeneration, nurse crops systems, as well as new approaches for plantation systems; effects of rotation length and stock density.
Deadline: Aug. 2015. Lead: PhD(RM) (1 paper). Lead: Palle Madsen.

Effects of climate change on procuctivity and changes of tree species distributions (SKA08, Finland, Bergh et al., cooperation with WP 3).
Deadline: Aug. 2015. Lead: Johan Bergh.

6. Synthesis - potential for increased biomass production by 2050 (T4-S7)
Analyses, syntheses and estimates – effects of species, management models, climate change, fertilization and breeding for relevant site types and up scaling to overall Nordic level.
Deadline: Aug. 2015. Lead: Lars Rytter.

Field installations

1. New fertilization experiments (T2) in selected stands – growth, nutrient losses, and GHG emissions
The task starts with compilations of existing experiments country wise.
Deadline: October 2012. Lead: Inge Stupak.

2. Field/demonstration experiments of management models (T3) for different species
The task starts with compilations of existing experiments country wise.
Deadline: Oct. 2013. Lead: Lars Rytter.
