Exploring the Diversity of Trees in Ireland's Mixed Native Woodlands

Ireland's mixed native woodlands, composed mainly of oak alongside ash, alder, birch, and hazel, embody the country's rich heritage, culture, and biodiversity 1 2. The combination of broadleaved, deciduous trees and the unique presence of evergreens like holly and yew highlights the diversity within these woodlands 1. With a mere 2% of Ireland covered by native broadleaf trees including oak, these woodlands face challenges but also hold opportunities for conservation and community engagement 6. This article explores the vibrant array of tree species thriving within Ireland's mixed native woodlands, underscoring the importance of preserving such critical ecosystems.

Key Tree Species in Irish Mixed Native Forests

In our exploration of Ireland's mixed native woodlands, it's essential to highlight the diversity and significance of key tree species that form the backbone of these ecosystems:

  • Broadleaves Predominate: Among the 28 native tree species, broadleaves such as Oak, Ash, Birch, and Hazel dominate, with only three native conifers: Scots Pine, Yew, and Juniper 78.

  • Sacred and Symbolic Trees: The Oak and Ash trees, once abundant and now rare due to overharvesting, hold a sacred place in ancient Celtic culture. Similarly, Holly trees were revered for their protective qualities 9.

  • Native Woodland Types: Ireland's native woodlands are classified into four principal types: Oak, Ash, Alder, and Birch woodlands, each further divided into 22 sub-types. This classification aids in understanding and managing these vital ecosystems 10.

These species and woodland types not only contribute to Ireland's biodiversity but also play a crucial role in cultural heritage and ecological balance.

Understory Plants and Their Contributions

Understory plants, often overshadowed by towering trees, are vital to the ecological fabric of Ireland's mixed woodlands. They not only contribute to biodiversity but also serve as critical indicators of the health and type of these woodlands, influenced by soil type, climate, and historical management practices 10.

  • Key Understory Species:

    • Wood Sorrel (Oxalis acetosella): Thrives in the shade, offering white or pink flowers 12.

    • Oakmoss (Evernia prunastri): A lichen used in perfumery, growing on oak and other trees 12.

    • Bramble (Rubus fruticosus agg.): Provides food for caterpillars, mammals, and pollinators 12.

  • Contributors to Ecosystem Dynamics:

    • Anobium inexspectatum, a wood-boring beetle, and Entelecara acuminata, a small black spider, highlight the intricate web of life extending from the forest floor to the canopy 12.

    • The Goldcrest (Regulus regulus), Ireland’s smallest bird species, and the Oak beauty (Biston strataria), a moth, depend on the understory for feeding and habitat 12.

The diversity within these woodlands is further enriched by mosses and liverworts, representing the greatest biodiversity among plants in these habitats 1. This underlines the understory’s role not just in supporting a variety of life forms but also in maintaining the ecological balance and health of Ireland's mixed native woodlands.

Challenges Facing Mixed Native Woodlands

In addressing the challenges facing Ireland's mixed native woodlands, it is crucial to consider a multifaceted approach that encompasses policy, conservation strategies, and public engagement:

  1. Policy and Economic Considerations:

    • Highlighting the ecosystem service values of native woodlands among policy-makers, the forest industry, and the public is essential 13.

    • The economic value of native woodland exceeds €67 million per year, underscoring the need for policies that realize this value and prevent its erosion through mismanagement 14.

    • Current government policies lack in providing continuous support, necessitating a shift towards policies that recognize and support the economic and ecological benefits of native woodlands 14.

  2. Conservation and Management Strategies:

    • Implementing continuous cover forestry techniques to harvest high-quality indigenous hardwoods and softwoods, particularly focusing on birch, alder, oak, and Scots pine 13.

    • The Native Woodland Conservation Scheme (NWC Scheme) plays a pivotal role in supporting the restoration, conservation, and enhancement of native woodlands, offering grants for various conservation activities 15.

    • Strategic creation of protective native woodlands near watercourses can improve water quality and mitigate flooding, a concern heightened by climate change 13.

  3. Research, Expansion, and Community Engagement:

    • Supporting research and adaptive measures to counteract threats from pests, diseases, and invasive species is vital for the sustainability of native woodlands 13.

    • Encouraging the expansion of woodland areas, especially in regions with high potential for amenity and water resource protection, can significantly benefit the environment and local communities 14.

    • Engaging communities in the conservation process and integrating native woodlands into the Natural Capital policy agenda will foster a collective effort towards preserving these vital ecosystems 1316.

Conservation Efforts and How You Can Help

As we delve into the conservation efforts and how you can help, it's imperative to recognize the structured support systems and initiatives in place, encouraging both public and private participation in the preservation of Ireland's native woodlands.

Native Woodland Conservation (NWC) Scheme:

  • Objective: Supports restoration, conservation, and enhancement of native woodlands 15.

  • Eligibility: Projects with high ecological priority, including ancient woodland sites and woodlands near conservation areas 15.

  • Benefits: Grants for various conservation activities and annual Payments for Ecosystem Services (PES) for private applicants 15 17.

Woodland Environmental Fund (WEF):

  • Purpose: Encourages businesses and landowners to expand native woodland resources 18.

  • Incentives: A once-off payment of €1,000/ha plus establishment grants and premiums for landowners 18.

  • Engagement: Businesses can work with Natural Capital Facilitators to quantify the environmental benefits of new native forests 18.

Practical Conservation Tips:

  • Diverse Age Structure: Maintain a variety of tree ages and use coppicing to manage dense areas 19.

  • Habitat Connectivity: Enhance connectivity with other habitats through buffer strips and additional hedgerows 19.

  • Wildlife Protection: Retain dead wood for nesting and add bat and bird boxes to encourage wildlife 19.

By understanding these schemes and adopting practical conservation measures, we can collectively contribute to the sustainability and enhancement of Ireland's precious woodlands.

FAQs

What types of trees are commonly found in Ireland's native woodlands?

Ireland's native woodlands are primarily composed of ash, oak, birch, and hazel trees. In areas with more moisture, alder trees are also common. There are two oak species native to Ireland: the pedunculate oak and the sessile oak, along with a hybrid species that results from the crossbreeding of these two.

Why are there hardly any native forests left in Ireland?

Originally, over 80% of Ireland was forested, but over the centuries, these forests were almost entirely cleared to make space for agricultural fields and pasture. By 1925, forest coverage had been reduced to just 1%. The remaining trees were found only in areas that were not suitable for any type of farming.

Can you tell me about the Native Woodland Conservation scheme in Ireland?

The Native Woodland Conservation (NWC) scheme offers grants up to €6,000 per hectare to farmers who participate. Announced by Minister of State Pippa Hackett, the scheme aims to aid in the restoration, conservation, and enhancement of Ireland's existing native woodlands.

Which county in Ireland has the highest forest coverage?

County Leitrim holds the title for the highest percentage of forested land in Ireland, with nearly 19% of its land covered by forests. It is closely followed by County Wicklow, with 17.9% forest coverage, and County Clare, with 17.2%.
