Is 'old growth' always about trees?

Primarily, yes. Its core meaning is ecological. However, it is occasionally used metaphorically to describe other complex, mature systems (e.g., 'old-growth institutions', 'old-growth code' in programming).

What's the difference between 'old growth' and 'rainforest'?

Not all rainforests are old growth (they can be secondary forests), and not all old growth is tropical rainforest (e.g., old-growth boreal or temperate forests). 'Old growth' describes the forest's age and lack of disturbance, while 'rainforest' describes its climate and precipitation.

Should I write 'old growth' or 'old-growth'?

Use 'old growth' as a noun phrase (e.g., 'We protect old growth'). Use the hyphenated form 'old-growth' when it functions as a compound adjective before a noun (e.g., 'an old-growth forest').

Are there any old-growth forests in the UK?

Yes, but they are small and rare fragments, such as parts of the Caledonian Forest in Scotland or ancient woodland sites. The term is fully understood and used in UK conservation.

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct calque like 'старый рост'. Use established terms: 'коренной лес' (primary forest), 'девственный лес' (virgin forest), or the loan translation 'олд-гроут лес' in specific contexts.

Common Mistakes

Using 'old grown' (incorrect). Using it as a simple adjective for anything old (e.g., 'an old-growth building'). Confusing it with 'old-age' or 'overgrown'.
