Danish Study: Planted Forests Sequester More CO2 Than Natural Regeneration, But Biodiversity Lags

New research from the University of Copenhagen shows that planted forests store more CO2 than naturally regenerated ones, at least in the early decades. The study, based on 20 years of observations on abandoned farmland, found planted stands had 16 times more above-ground woody biomass, meaning faster carbon uptake. But that carbon advantage comes with a biodiversity cost. Naturally regenerated forests support more plant species and complex structures. The authors say forest restoration projects should aim for a balance between quick sequestration and ecological resilience, not just chase the highest carbon number.

Interesting data point. Planted forests storing 16x more woody biomass after 20 years is a big number. But the article doesn't say how long that carbon stays locked up. Timber harvest could change the math. Would like to see the study's assumptions on permanence.

The biodiversity tradeoff is the real story here. Fast carbon capture from plantations vs slower natural regrowth with more species. Feels like the kind of nuance that gets lost in headline numbers. Good to see a study comparing both.

This has direct implications for carbon crediting methodologies. If planted forests are used for ARR projects, the baseline and additionality need to account for the biodiversity difference. Otherwise we end up with monoculture plantations getting credits while natural regrowth gets ignored. Policy should reward both.

Simple summary: planted forests pack more carbon early, natural forests build richer ecosystems. The study suggests a mix. Seems sensible. But the article doesn't mention the land use history or soil carbon, which can also matter.
