BirdWatch Ireland submission to Department of Agriculture Food and the Marine request for submissions on the Discussion Document on the potential for GHG mitigation within the Agriculture and Forest sector. BirdWatch Ireland BirdWatch Ireland is Ireland’s largest environmental NGO and is a science based conservation charity with 15,000 members, a team of professional staff and 2,000 active volunteers. BirdWatch Ireland has been actively engaging in the issue of Climate change for more than 10 years, seeking action on climate change mitigation and adaptation from all relevant sectors of society. Introduction Irish agriculture is a very important indigenous sector in Ireland providing a substantial number of jobs and supporting rural families. Agriculture is also important for biodiversity as our species have evolved over the millennia in tune with this land use. We acknowledge that significant research and work has been conducted by Teagasc, the Department of Agriculture, Food and the Marine, and others to assess and determine the carbon footprint of Irish agriculture and opportunities to mitigate against this. Emissions from agriculture are projected to continue to increase into the future with the expansion plans of Food Harvest 2020, when emissions should actually be decreasing in order to prevent the worst effects of climate change. While it is laudable that the DAFF is seeking views on the potential for GHG mitigation within agriculture with the view to developing a sectoral mitigation plan, this is in the context where the legal mechanism for it, the 2015 Climate Change Bill, has not yet been agreed by Government and the discussion is proposed in the absence of guidance and objectives of a National Mitigation Plan. However, BirdWatch Ireland welcomes the opportunity to comment on this Discussion Document. 1
The projected impacts of climate change on our planet and people, especially the most vulnerable people in developing countries, are potentially devastating. Climate change will also impact biodiversity including birds and their habitats. We must do everything we can to reduce greenhouse gases and reduce these impacts. The intensification of agriculture under Food Harvest 2020 with resulting greenhouse gas increases coupled with the proposed significant afforestation in the Forestry Programme2014-2020 to mitigate against this could result in substantial changes to land use in Ireland with implications for birds and their habitats. Climate Change Impacts on Biodiversity Climate change is anticipated to affect all the levels of biodiversity, from organism to biome levels (Bellard et al 20131, Mokany et al 20132, Pereira et al 20103). Changing temperature and precipitation (IPCC, 20074) are expected to interact with other pressures (e.g. habitat fragmentation and loss) to influence biodiversity negative and in some cases, positive ways (Hagerman et al 20105). Species with reduced climatic ranges, specialist habitat requirements and small populations are potentially the most vulnerable to extinction and includes especially mountain species and biota restricted to islands (IPPC 2007; Adam 20096, Loarie et al 20097, Thuiller et al 20058, Walther et al 20059). The habitats of many species will move poleward or upward from their current locations (IPCC 2007, Hickling et al 200610, Tamis et al 200511). Although there is relatively limited evidence of current extinctions caused by climate change, there are many examples of observed impacts on biodiversity including changes in phenology (Donnelly et al 201112), alpine plant species in Switzerland moving up hillsides (Walther et al 2005) and birds migrating further north (Lehikoinen 1 Bellard, C. et al., 2012.

and Sparks 201013). It has been suggested that climate change could surpass habitat destruction as the greatest global threat to biodiversity over the next few decades (Bellard et al 201314, Leadley et al. 201015, Rose et al 200916, Opdam & Wascher 200417). Climate change will cause further losses of habitats and species that are already experiencing severe declines from habitat loss, degradation, and fragmentation and disturbance. Protected areas must be afforded greater protection, management and connected to provide a “backbone for biodiversity” and to accommodate the expected changes in species distribution. In addition, the landscape outside these areas must become more ‘permeable’ to species’ movements by providing stepping stones of high quality habitat and by more sustainable land-use policies. Farmland Birds and Agriculture in Ireland Ireland’s biodiversity is facing very severe threats, as evidenced by declining populations of many farmland birds and the loss in extent and quality of many semi-natural habitats in the mosaic of Ireland’s farmed landscapes. Farmland birds across Europe have declined by over 40% in the past 30 years. In Ireland, many previously common farmland birds have suffered major population and range declines since the 1970’s18. While Ireland has been farmed for millennia, farming practices existed alongside healthy ecosystems. In recent decades we have drastically changed the way we farm and used farmland. Declining bird populations often indicate declining health of the natural environment. They reflect losses in habitat extent and quality and often equate to losses in ecosystems services which are a valuable asset to Ireland. Target 3(A) of the EU Biodiversity Action Plan states “By 2020, maximise areas under agriculture across grasslands, arable land and permanent crops that are covered by biodiversity-related measures under the CAP so as to ensure the conservation of biodiversity and to bring about a measurable improvement in the conservation status of species and habitats that depend on or are affected by agriculture and in the provision of ecosystem services as compared to the EU2010 13 Lehikoinen E, Sparks TH (2010) Changes in migration.

Baseline, thus contributing to enhance sustainable management19”. The Overall Target of Ireland’s National Biodiversity Plan is “that biodiversity loss and degradation of ecosystems are reduced by 2016 and progress is made towards substantial recovery by 202020”. Ireland’s Biodiversity Action Plan also has a specific target for biodiversity in the wider countryside to “optimise use of opportunities under agricultural, rural development and forest policy to benefit biodiversity.” Internationally, Ireland has obligations for biodiversity conservation at a European level (preventing biodiversity loss is a priority for the Europe 2020 strategy)21 as well as globally22. In addition to the delivery of national and international commitments on biodiversity conservation, and the recognised need to integrate actions toward this end into agriculture and other sectors, sustaining biodiversity also has many positive benefits for farming in itself. These are services provided by biodiversity which we would otherwise have to pay for ourselves. They are often under- estimated and under-valued even by the agri-food sector, and include pollination, predator control, maintenance of soil fertility and structure and water management services23. According to Bord Bia and others in the agri-food sector, the perceived green image of Ireland gives us a significant competitive advantage when marketing our products abroad. If we are to maintain this image, we need to move urgently to proactively support biodiversity and ecosystem services in the farmed landscape and implement measures where species and habitat losses are most pressing. It is well- documented that many modern, intensive farming practices leave little space for birds or biodiversity24. Many birds that use farmland habitats that were previously common have suffered major population declines since the 1970’s. In Ireland, these include Kestrel, Skylark and 19 Communication from the Commission to the European Parliament, the Council, the Economic and Social Committee and the Committee of the Regions: Our life insurance, our natural capital: an EU biodiversity strategy to 2020.

Yellowhammer, with Corn Bunting (a tillage-specialist) becoming extinct as a breeding bird in Ireland, with the last confirmed breeding in the 1990s25. Birds are indicators of the health of the countryside. Like the “canary in the coalmine”, birds can provide early warning systems for the degradation or loss of ecosystems, and the services such ecosystems provide. Birds satisfy many of the criteria of effective indicators, are often used as an early-warning system to detect emergence of environmental problems, and have been widely used to inform decision making and land use management policy including within agricultural ecosystems26. The decline in farmland bird populations is telling us that we need to do more to maintain a healthy balance of nature across Irish farmland. Any proposals in a future Mitigation Plan which demonstrates the sources, sinks and stores of carbon relating to agriculture must ensure that biodiversity and especially birds and their habitats do not lose out. The intensification of the dairy sector under FH2020 requires that the vast majority of good agricultural land be utilised in intensive pastoral faming systems. This is driving the forestry sector to target marginal land for afforestation with conifers. At both a regional and national scale this marginal land is all too often the land that has seen the least intensification. These low input areas are often the last refuges for many species which have been marginalised by the intensification of agriculture. In this way afforestation is resulting in the direct loss of endangered habitats and species. High Nature Value farmland including Ireland’s designated SACs and SPAs are being afforested. This deleterious trend is most obvious in our uplands and riparian SACs. It is noted that unenclosed or marginal land is targeted by the Forestry Programme and this will reduce further the habitats available for our native birds. BirdWatch Ireland has already raised concerns related to the likely environmental impacts of Food Harvest 2020 (FH2020) and the role of Ireland's Rural Development Programme. The Environmental Analysis Report (EAR) of FH2020 identified that FH2020 actions would have a negative impact on the environment, including biodiversity. Although the level of this negative impact is debatable, it is agreed that FH2020 actions will damage Ireland's environment. However, the EAR suggests that these negative impacts could be mitigated through actions within the RDP. FH2020 has been proposed as a vision led by the Irish agri-food industry, and is not government policy. As a result, the 25 Lynas, P., Newton, S.F. & Robinson, J.A. 2007.

polluter-pays principle states that it should be the Irish agri-food sector that is responsible for addressing negative environmental impacts arising from FH2020 actions rather than European taxpayers (through the RDP). Discussion Document Points Greening in Pillar One-Hedgerows: In the Discussion document there is a description of the Greening measures Irish farmers need to comply with in order to receive their Basic Payment. The Ecological Focus Areas are a requirement for a relatively small number of arable farmers in Ireland. The Hedgerow greening measure for these farmers allows a farmer to receive 100% payment for a 100m hedgerow which only contains 20% vegetative material dispersed over the 100m (i.e. gappy hedges) and which can include briars. How does this qualify as a hedgerow? Our hedgerow network sequesters carbon (estimates suggest that hedgerow and nonforest woodlands could potentially sequester 0.66–3.3 t CO2/ha/year27). This current greening measure under Pillar 1 in the CAP (2014-2020) does not adequately contribute to achieving environmental targets. Farmers should be required to plant up gappy hedgerows with tree/shrub stock of native Irish provenance in order to receive their payment to ensure that the full payment means that a full 100m of hedgerow exists and to further contribute to carbon sequestration. Knowledge Transfer: BirdWatch Ireland fully agrees that one of the most appropriate ways to achieve the FH2020 targets is through an improved training and advisory programme. Such a programme would not only enhance the benefit of actions under FH2020, but also help deal with environmental risks from the FH2020 actions. Once risks are identified, appropriate measures can be taken to either avoid potentially damaging actions, or better deliver mitigation measures to avoid them. Such a training and advisory programme must include environmental expertise to ensure damage is minimised and positive benefits for the environment, and the associated benefits this has for the agri-food sector, can be maximised. An assessment of the levels of environmental education within Teagasc, Agricultural Education Courses in Kildalton College was presented at the Teagasc Agri-Environment Conference in Tullamore in November 2014. When students were asked how significant is the role of agriculture in 27 Black, K., Green,S., Mullooley, G., & Poveda, A., (2014) Carbon Sequestration by Hedgerows in the Irish Landscape, Ireland; Environmental Protection Agency. 6
Irelands greenhouse gas emissions, 51% stated that it had some significance, 38% stated that it was very significant with 11% stating that it had little or no significance. When students were asked how important is the area of biodiversity to Irish agriculture 71% said it was slightly important with 13% saying it was extremely important and 16% saying it was not important. These results would imply that there is a lot more work to be done to educate young farmers on the importance of climate change and of reducing emissions in agriculture as well as the importance of biodiversity which underpins agriculture. The presentation on the research is available here: http://www.teagasc.ie/publications/2014/3366/Environmental-Conference-Gerard-Griffin-PP.pdf. Bionergy: Targeted Agricultural Modernisation Schemes II (TAMS II) Under the section on bioenergy it is stated that there are “Potentially positive impacts on biodiversity, most notably invertebrates and birds, through the provision of additional types of habitats”. This statement needs to be backed up by research on the impacts on biodiversity and birds. Currently, there is no known research in Ireland on the impacts, positive or negative, of Short Rotation Coppice on birds. Forestry and Bioenergy as Mitigation for Agricultural Emissions In the European Council Conclusions of October 2014 ‘the Commission is to examine the best means of encouraging the sustainable intensification of food production, while optimising the sector's contribution to greenhouse gas mitigation and sequestration, including through afforestation. Policy on how to include Land Use, Land Use Change and Forestry into the 2030 greenhouse gas mitigation framework will be established as soon as technical conditions allow and in any case before 2020’. From the Discussion document, it is clear that forestry and bioenergy are suggested as the offsets for agriculture-related greenhouse gases. The consultation process accompanying the proposed National Mitigation Plan should be the mechanism whereby the public is given a voice on how we should decide on national mitigation for greenhouse gases using the available reservoirs and sinks of carbon. Some other questions which may need to be addressed and clarified in the mitigation plan relates to ownership of the store of forest carbon and to which sector will the benefits of the store be attributed for mitigation? If the government provides grants to landowners for forestry plantation does the government own all or part of the sink/reservoir of carbon? Is it possible that the non-grant aided amount of forestry could be used to offset emissions from other sectors including possibly the private sector? 7
The permanence of the forestry stock taking in to account the risks associated with wind blow, disease, fire etc along with the potential for Double Counting needs to be taken into account in the carbon budget and to verify the carbon sequestration potential as proposed in the Discussion document. It will be essential that forest stocks are chosen that can adapt to a changing climate. Due to a warming climate, there is a need to select and use species that are more suited to the potential future changes in climate. Native Irish species of Irish provenance should be researched for their potential adaptability to climate change and the appropriate stock chosen. “In general most broadleaved species have a higher carbon content than conifers but this is offset by their lower rate of growth, although in species with very long rotations (i.e. >100 years) such as oak, the carbon stocks averaged over time can be higher than in faster growing conifer stands.28” All of the potential impacts of forestry expansion including road construction will need to be taken into account in the greenhouse gas emissions sinks and sources and their mitigation. “The construction of forest roads and subsequent increase in traffic and felling and thinning activities is likely to increase CO2 emissions”29. Forestry expansion & main potential impacts on birds The proposed expansion of forestry under the Forestry Programme 2014-2020, if implemented, will lead to substantial change to the Irish landscape with potentially significant impacts to birds and biodiversity. Research has shown that ‘forest management for the benefit of birds should focus on increasing the structural diversity of forests’30. Considerations of impacts of our existing forest cover and planned expansion on our native bird communities, particularly those of grassland, upland moorland, riparian and lake & fen habitats include; Changes in water quality and water retention: Potential impacts through the acidification of watercourses, particularly those with low-buffering capacity and knock-on negative impacts on prey abundance (invertebrate/fish spp.) and for birds associated with riverine, lake & fen habitats (e.g. Dipper, Grey Wagtail, Kingfisher, Common Scoter, Tufted Duck, Great-crested Grebe) and breeding productivity (e.g. Dipper31) Displacement disturbance: For example - Loss of open upland heath/bog habitat to new plantations has direct impacts on upland breeding birds through displacement. Those which prefer open landscapes include breeding waders (Golden Plover, Curlew, Dunlin), Raptors 28 Forestry Commission, Woodland Carbon Code (2014) Woodland Carbon Code [online], available: http://www.forestry.gov.uk/forestry/infd-883l84#5, [accessed 20/3/2015] 29 Department of Agriculture, Food and Marine (2014) Environmental Report of the Forestry Programme 2014-2020. 30 Sweeney, O., Wilson, M.W., Irwin,S., Kelly, TC., Gittings, T., and O’Halloran T (2011) Breeding birds of native woodlands and plantation forests in Ireland.

(Hen Harrier, Merlin, Peregrine), Raven, Red Grouse etc. Also, the effect of habitat fragmentation and/or edge effects of forestry on the distribution and ecology of key species require consideration. Loss of feeding areas: Particularly important for raptor species. For example, open country species abandon afforested areas once trees get above a certain height. The distinction between pre-thicket and closed-canopy stages is important in this instance. Changes to predatory regime: Studies have shown that increased forest cover can raise numbers of predators in an area (e.g. observed impact on upland breeding birds32). Physical impacts of forestry activities: Studies have shown impacts on watercourses, (changes in pH and heavy metal concentrations) catchment soils, geology and erosion rates. Habitat change: Impacts of drainage on underlying habitat and habitat quality knock-on impacts on food availability for bird species (e.g abundance of invertebrates and preferred prey items). Chemical spraying: Use of pesticides and herbicides on invertebrate composition and abundance is well documented, while fertiliser use can cause increases in vigorous grasses such as Molinia in areas adjacent to forest stands, which reduces plant species diversity and the suitability of sites for breeding waders. Conclusion Agriculture is in the process of intensification in Ireland with projected increases in greenhouse gases. This intensification will cause impacts to birds and their habitats. Sustained and increased afforestation is being proposed as the main ‘offset’ for the emissions from agriculture and this land use change will impact on birds and their habitats. The proposed changes to land use in Ireland could be a triple whammy for birds in Ireland. They need to be further investigated to ensure that birds, their habitats and biodiversity in general is not only not impacted further and that any impacts are mitigated against but that habitat structure and function is restored and species populations are increased thereby improving resilience to climate change. We also need a debate on land use policy in Ireland and how we envision our country in 50 to 100 years time. A report by the German Federal Agency for Nature Conservation states “As has been pointed out by the Millennium Ecosystem Assessment the components of biodiversity (at the levels of genes, species and ecosystems) form the basis for the provision of ecosystem services, many of which are 32 Avery, M.I. & Leslie, R. 1990.

central to human well-being. However, we cannot determine with certainty which specific genes, species, communities or ecosystems are critical for specific ecosystem services in a given situation. Added to this, changing climate conditions will undoubtedly change these relationships, and so losing any element of biodiversity is likely to reduce the potential for continued provision of ecosystem services. Thus, any climate change-related measure or policy – and indeed any other policy - that has negative impacts on biodiversity risks being counter-productive. All such policies and activities should therefore be carefully designed to minimize negative impacts on biodiversity”33.
