This paper considers the place of ecology and environmentalist thought in Paul Muldoon's postcolonial poetry. Employing the principles of postcolonial ecocriticism, the study throws light upon Muldoon's poetical works where the Irish-American poet tries to preserve his native agricultural identity and tradition in face of the global Anglo-American culture. In most of his verse volumes, Muldoon mentions agrarian and green aspects as well as native rustic jargon, which helps enliven and strengthen his native Irish roots, and shield the Gaelic region's distinct cultural and linguistic heritage. The poet's portrayal of local landscape phenomena entails intellectual and emotional intimacy. He is personally attached to Irish ecological spots, and they are venues in which he finds a considerably remarkable meaning ,i.e., solid ground on which the anti-conquest's cultural-lingual resistance stands. The private ( and public) worth of this georgic atmosphere helps foster both the poet's and his natives' stance against a plotted process of naturalization. Muldoon's poems, too, show how postcolonial corporeal and cultural effect endeavours to boom throughout human and environmental worlds.
