Research and teaching focus: Forest ecology

A professional forester (Member of the Institute of Chartered Foresters)

and I manage my two woodlands: 5 ha of beech and Scots pine plantation on an ancient woodland site in the Conwy valley and 2 ha of recently established very mixed-species broadleaved woodland in west Cheshire.

Also a member of: Royal Forestry Society, Commonwealth Forestry Association, International Society of Tropical Foresters, Small Woods Association, British Ecological Society, International Association for Landscape Ecology and North Wales Wildlife Trust

Section Chief Editor for the journal Frontiers in Forests and Global Change

I recently contributed to a Podcast on "Our future forests" for WoodKnowledge Wales:

And I wrote an article for The Conversation on 'How to recognise a temperate rainforest in Britain and Ireland when you see one'

Professor John Healey researches the ecology, management and ecosystem services of forests and agroforestry systems. Key themes include the role in the global carbon cycle of forests^1,2,3 and their products^4,5, climate change impact on forests^6,7 and coral reefs⁸, forest biodiversity conservation at species⁹, site^10,11听and landscape scales¹², including the impact of invasive species¹³听and pathogens¹⁴, drivers of forest degradation¹⁵, the ecological basis of forest restoration¹⁶听and sustainable forest management^17,18, and the role of culture in the resilience of socio-ecological systems¹⁹.听 Research on agroforestry includes its role in livelihoods²⁰听and mitigating deforestation and climate change²¹.

• Insect herbivores and fungal pathogens alter seedling performance, abundance, and diversity in mature forests. Their role in secondary succession, i.e., rainforest recovery, remains however understudied. Interactions between plants and their natural enemies could drive successional shifts in seedling community composition if they vary with plant functional type (PFT) and species鈥� local abundance or favor unrelated successors. We present two research projects on the impact of natural enemies on successional seedling community dynamics across two Panamanian chronosequences.

  First, we conducted greenhouse experiments to assess how soil successional age (0-, 15-, 25-, 115-yrs) affects fungal-mediated plant-soil feedbacks (PSF) on germination and survival of seven tree species. Tree species varied in their association from early- to late-successional forests and their phylogenetic distance to each other. We found lower susceptibility of late-successional species, suggesting a potential decrease in importance of PSFs with increased forest age. Overall, species experienced more positive PSF in soil ages at which they peak in abundance, indicating that species-specific mutualists promote establishment of species at their associated successional stages, potentially slowing down successional turnover. Negative heterospecific PSF decreased with phylogenetic distance, favoring unrelated successors and possibly accelerating diversification.

  Second, an ongoing field experiment explores the effect of insects and fungi on seedling communities in seven forests regrowing for 9, 49, 69, or 99 years. In each forest, three treatments (insecticide, fungicide, water-sprayed control) are applied to 26 1m2 plots each. All woody seedlings (5-130 cm) are identified to species level and grouped into PFT based on growth form (tree, liana) and demographic strategy. We monitor seedling survival and growth biannually for two years.

  Integrating findings of our greenhouse and field studies will advance our understanding of successional and PFT-specific variation in the effects of natural enemies on seedling communities, which play a crucial role in shaping future forest composition and diversity.

• Bangor research (in multi-institutional collaboration) cited in paper providing an overview of refined IPCC default values for tropical and subtropical forest aboveground biomas:

  For monitoring and reporting forest carbon stocks and fluxes, many countries in the tropics and subtropics rely on default values of forest aboveground biomass (AGB) from the Intergovernmental Panel on Climate Change (IPCC) guidelines for National Greenhouse Gas (GHG) Inventories. As part of the 2019 Refinement to the 2006 IPCC Guidelines for GHG Inventories, we updated the default AGB values for tropical and subtropical forests based on AGB data from >25鈥�000 plots in natural forests and a global AGB map where no plot data were available. We calculated refined AGB default values per continent, ecological zone, and successional stage, and provided a measure of uncertainty.

  The refined values will ultimately lead to improved policies to mitigate climate change, using data based on improved evidence.听

  Disgrifiad

  The active phase of the project ran from May 2009 until September 2011 but the valued network of local farmers built-up during this time along with the goodwill and trust shown to project officers by the farmers and their Unions will hopefully live on long beyond the project.

  The results and findings of the project are reported in a project handbook which has been uploaded onto this website and also exists in paper form and can be requested free of charge from: Nia Evans, RDP Project Development Officer, Community Development Service 鈥� Rural, CONWY County Borough Council.
