'woodland-related' originates from English, specifically the words 'woodland' and 'related', where 'woodland' comes from Old English elements 'wudu' (wood) + 'land' (land) and 'related' is from the verb 'relate' (from Latin 'relatus' via Old French 'relater').

'wood' changed from Old English 'wudu' and 'land' from Old English 'land'; 'relate' developed from Latin 'referre' (past participle 'relatus') through Old French 'relater' and Middle English into the modern adjective 'related', and the compound 'woodland-related' is a straightforward modern English formation combining those elements.

Initially the component words referred separately to 'wood/land' and 'being related'; over time the compound has come to mean collectively 'pertaining to or associated with woodland', a descriptive adjective used in modern English.
