In the current climate ecolinguistic research has arguably never been more important, as its basic premises regard the survival of life on Earth and key philosophical questions hitherto under-acknowledged by mainstream science. In recent decades, environmental thinking has made great advances in shaping current opinions towards nature and the non-human world. The goal of this paper is to explore certain currents of mediated thinking in modern Britain regarding nature, in order to assess how far expressions of sorrow for the felling of a prominent tree might correspond to a genuine ecological sentiment. The study explores public responses to an apparent case of eco-vandalism, the felling of the Sycamore Gap tree in September 2023 in Northumberland, using data taken from social media and other online sources such as e-newspapers. From the point of view of Ecolinguistic theory and that of Positive Discourse Analysis it applies critical lenses such as Evaluation and Discourse Pragmatics to dig beneath the surface of texts produced on the topic, in order to explore diverse current attitudes to trees in the UK. The paper finds that, though there are instances in which people appear to express grief for the loss of the Sycamore Gap tree, it is possible to account for these in ways that lessen the likelihood that they are motivated by purely ecological sentiment. In practice human attitudes towards trees tend to be superficial and instrumental, and this tendency is also found here. The Sycamore Gap event brings many latent social attitudes into play, and this paper thus contributes to the developing field of Ecolinguistics by focusing on tree-centred narratives, distinguishing between inherent ideologies of pseudo- and authentic environmental sensitivity.
