Autumn represents a crucial period for wildlife sustainability and habitat upkeep across Ireland, where over 60% of the land is devoted to farming. The decisions made by farmers during September, October, and November have direct consequences for the wellbeing of local ecosystems, the survival of overwintering animals, and the protection of native biodiversity.
Ireland boasts an extensive network of nearly 689,000 kilometres of native hedgerows composed of species such as whitethorn, blackthorn, elder, holly, and hazel. These linear habitats become essential ecological corridors and feeding grounds during autumn. Since the cutting ban lifts on 1st September, farmers are shifting towards biodiversity-friendly hedge management by preserving mature fruit-bearing trees and maintaining an A-shaped profile. This approach ensures berries and nuts remain available to birds like thrushes and finches, as well as small mammals preparing for winter.
Beneath the surface, autumn marks a vital transition for pasture soils. The increasing use of multi-species swards—comprising perennial ryegrass, clovers, and herbs—supports richer root systems that improve soil health by fostering beneficial organisms and enhancing water absorption. Additionally, agri-environmental schemes encourage farmers to maintain buffer strips along waterways to trap nutrients and sediments, safeguarding aquatic life such as Atlantic salmon and otters during their spawning and overwintering periods. For tillage farmers, leaving cereal stubbles and wild bird cover crops unploughed provides critical food and shelter for seed-eating birds through the colder months, while integrated pest management helps combat threats like Barley Yellow Dwarf Virus during autumn sowing.
