Abstract Variation in decay rates across woody species is a key uncertainty predicting the fate of carbon stored deadwood, especially tropics. Quantifying relative contributions biotic agents, particularly microbes and termites, under different climates with diverse wood traits could help explain this variation. To fill knowledge gap, we deployed stems from 16 plant native to either rainforest ( n = 10) or savanna 6) northeast Australia, without termite access. For comparison, also standardized, non‐native pine blocks at both sites. We hypothesized that termites would increase deadwood conditions limit microbial activity. Specifically, should be greater dry constrain decomposers. Termite discovery was surprisingly low only 17.6% 22.6% accessible discovered respectively. Contrary our hypothesis, by decomposed faster rainforest. Termites decayed higher than savanna. found significant variation within same site. Although explained 85% decay, they did not termite‐driven decay. undiscovered were nutrient concentrations syringyl:guiacyl lignin ratios but lower densities. Synthesis . Ecosystem‐scale predictions turnover storage account for impact on decomposer communities. In tropical expected ground. Even if are present, may always decomposition fallen forests. Our study shows how drivers differ between Australian savanna; further research test whether such differences apply world‐wide.
