Show Notes

Today I speak with Kenny McCauley from McCauley Wood Fuels Ltd who are based near Mohill in Co Leitrim. The business processes around 500 tonnes of wood biomass weekly to create high quality, moisture controlled wood chip. In this conversation Kenny explains how his business works, how biomass forms a vital cog in the Irish forestry supply chain, how wood chip is replacing fossil fuels across Ireland and how Leitrim can be a centre of excellence for balanced forestry. He also details the processing system he uses including the machinery and technology involved. Finally Kenny has recently started on his journey as a Nuffield Scholar for 2026. So we discuss what Nuffield involves and his study topic itself which is: “Mobilising rural biomass: unlocking renewable heat, carbon storage and bioeconomy value from farm forest resources.”

Key Points: Firewood to biomass - transitioning his business and partnership with Arigna Fuels Partnerships with suppliers and early customers proved critical in enabling the business to grow. Quality control of both inward raw materials and finished product remains key. Biomass is a cost effective source of heating for large users such as poultry, pig, and mushroom farms, as well as hotels. Leitrim's potential as an economic driver through a balanced forestry model. The Sustainable Energy Authority of Ireland offer the Support Scheme for Renewable Heat which aids large users transition away from fossil fuels. Kenny's journey with Nuffield will give him an opportunity to understand best practice worldwide and emerging opportunities.

Today I speak with Kevin O Connell, Forestry Advisor at Teagasc - Teagasc are Irelands national agriculture and food development authority and Kevin's role is to advise Irish forest owners about how to best manage their forests. Today we discuss some of the reconstitution schemes the Irish Government offers owners. We start off by discussing the Climate Resilience Reforestation Pilot before moving on to the Windblow Scheme and finally the Ash dieback scheme. Each scheme has its own focus and nuance as you'll hear but all offer financial assistance to replant your site and in some cases, make other payments such as the annual Payments for Ecosystem Services available. While replanting involves challenges, Kevin emphasises that it offers a great chance for owners to reset the clock and grow a new forest that aligns with your objectives.

Today I speak with Regional Forest Inspector Seppi Höna about national efforts to address spiraling deer numbers in Ireland. We discuss the problems deer create in forestry and also what the scale of the problem is. Seppi explains how a national strategy group is providing direction for DMU's deer management units, which are now operational across the Republic of Ireland. We chat about whether we need more incentives to cull deer, about ethical and operational considerations relating to culled deer being left on the hill, as opposed to being recovered for venison. Finally, there are supports for deer protection in new forests, so we discuss these and other strategies forest owners can take to protect their trees. Seppi Höna is a Regional Forest Inspector and Forest Service Inspector at the Department of Agriculture, Food and the Marine in Ireland. He has chaired key committees for the Irish Deer Management Strategy Group (IDMSG) and presented on the impact of deer in Irish forestry.

Today I speak with forester Paddy Purser - Paddy was an early Irish advocate for continuous cover forestry (CCF) and a key figure in the establishment of Pro Silva Ireland who promote CCF's adoption. We speak about the enhancement of native and broadleaf forestry through timely and appropriate interventions and how this can lead to a wide range of commercial, silvicultural and biodiversity benefits. The Woodland Improvement Scheme grant assists owners of native and broadleaf forests to manage their forests and so we talk about how the scheme works and how it supports both a clearfell and a continuous cover management approach. And finally we briefly discuss a longer term vision Paddy has - to see Ireland once again covered in oak trees that are managed both for timber and ecological benefit. We don't specifically address grant payment rates as these can change intermittently but links to find out more can be found below. This podcast is supported by the Irish Department of Agriculture Food and the Marine. If you're thinking of planting a new forest or if you want information on financial and technical supports to manage your existing forest then go to http://gov.ie/forestryforyou Key Points: Paddy discusses the various types of broadleaf forests in Ireland, including ancient woodlands, old estate woodlands, and newly planted broadleaf forests. Each type has its unique management needs and ecological significance: Ancient Woodlands: These are continuous woodlands that have existed for centuries, often rich in biodiversity. Old Estate Woodlands: Typically mixed woodlands that were historically maintained for estate boundaries, some timber production and/or game rearing. Newly Planted Broadleaf Forests: These are often part of the Government supported afforestation programs, with a growing emphasis on integrating broadleaf species into monoculture conifer plantations. Paddy identifies three primary motivations for landowners to engage in broadleaf management: Commercial Viability: Exploring the potential for timber production. Silvicultural Reasons: Improving stand development and forest health. Biodiversity: Enhancing ecological diversity within forest ecosystems. Paddy then explains how interventions to enhance standing timber from a commercial point of view must be taken at appropriate stages of development. Beyond formative shaping, Paddy explains how thinning racks are a prerequisite for almost everything that comes afterwards and he gives some examples of what that looks like. Quotes: "There has been a significant cultural shift in how forest owners perceive their broadleaves, moving towards a more management-oriented approach rather than seeing them as unproductive areas." "If you talk or run any poll on what kind of woodlands people want, they want native Irish forests." "Continuous cover forestry is defined by what it isn't rather than what it is. It's about creating a sustainable management approach that benefits both the forest and its biodiversity." "You can't retrofit quality at a late stage into broadleaves, it has to be instilled at the very beginning." "For thousands of years, oak was our main commercial species. in the last hundred years it hasn't been. But I would say there i it is highly likely that it will become our main commercial species again."

Native Woodlands in Transition with Kate Harrington In this podcast I speak with experienced ecologist Dr Kate Harrington about her recently published research into native woodlands primarily planted in the last twenty years. We know that native woodlands benefit nature but today Kate and I discuss exactly what that looks like in these forests. Kate carried out extensive field research which revealed subtle but critical changes to specific pollinator species and other indicators as the woodlands aged - given the vast range of other variables on every site this proved hugely significant as a gauge of woodland development. We speak a little about the where and why these forests were planted, about how they interact with the farming landscapes they often exist in, about the edge effect, and we also touch on a few simple measures a forest owner can take to maximise personal enjoyment and nature enhancement.

In this interview I'm joined by Colm Gilheaney, Establishment Manager at Western Forestry Co-Op. We discuss everything you need to know if you're considering planting a new broadleaf forest in Ireland. Colm gives me an overview of the Irish Government forestry programme, what it pays for and for how long. Farmland that is considered for planting is always surveyed and Colm explains how this feed into the type of forest the owner applies for. The Irish Forestry Programme supports 7 distinct broadleaf forest types and Colm highlights the crucial aspects of each and which might be best suited for the land in question. Finally we talk through the application process itself, who manages the planting, the maintenance and everything in between. Colm Gilheaney is the Establishment Manager at Western Forestry Co-Op. He joined Western Forestry Co-op in 2015 and is based in the Sligo office managing the afforestation team and projects predominantly in counties Sligo, Leitrim, Roscommon, Donegal, Cavan, Longford, Monaghan. Colm is a technical member of the Society of Irish Foresters and a Native Woodland Scheme accredited Forester. This podcast is supported by the Irish Department of Agriculture Food and the Marine.
