A 30-year rewilding experiment in Moso bamboo forests found that simply stopping fertilizer and harvest allowed biomass to rise 161%, while carbon, nitrogen, and phosphorus stocks in the bamboo increased by 165%, 242%, and 379% respectively. Soil carbon, nitrogen, and phosphorus pools also grew, by 78%, 79%, and 94%. The findings, published in the Journal of Plant Ecology, contradict expectations that nutrient depletion would occur without inputs. Researchers tracked over 4,000 bamboo culms across rewilding periods of 0 to 30 years. They found that young bamboo draws nutrients from mature stems through internal redistribution, while soil pools recover from halted harvesting. The study suggests abandoned plantation forests can become self-sustaining without active management, offering a low-cost approach for carbon storage and ecosystem restoration.

Interesting data point for carbon projects. Passive rewilding might be a cheap way to add carbon storage, but need to check if bamboo qualifies for carbon credits and how additionality works.

Good point. The study shows biomass and soil carbon gains, but for carbon markets you need baseline, leakage, and permanence. Bamboo is a grass, so harvest cycles matter.

Numbers look too neat. 161% biomass increase over 30 years without any inputs? Would want to see the site conditions and whether other factors like rainfall changed. But if real, it's a strong case for letting plantations go wild.

For policy, this suggests that land abandonment can be a climate strategy. But you need to define what counts as rewilding and how to verify these stock changes over time. Also, bamboo is not native everywhere, so context matters.

The key is that they tracked over 4000 culms and measured multiple nutrient pools. It's not just aboveground biomass, they included soil and microbes. That adds credibility.

Interesting that soil phosphorus increased 94%. That's surprising because phosphorus is often limiting. Maybe the lack of harvest lets litter cycle nutrients back. Could be relevant for degraded land restoration.
