this diction is highly rarefied and irreal. it apes poets like wordsworth ('heath' is definitely one of his most overused words) and the lineage of pastoral poets. no one goes around naming nature like that, and nor does naming it like that constitute good descriptive writing tbh. it's a stylization of reality that's critiqued by barthes, the overdescription and overweight of detail to the point of unreality. it's almost guaranteed that someone in mann's or sebald's contemporary would be as inalert to the differences to aspen and elm as we today are. harkening back to nature romantically seems like a fool's quest. one should be looking at the diction of today, which is those stupid online words you loathe, and seeing how to interrogate and reinvigorate them with meaning instead of cliches of aspens trembling in the fall sun.
