Abstract In many tropical ecosystems, termites are important ecosystem engineers. Mound‐building termite species often contribute to topographical landscape heterogeneity, and the associated accumulation of soil moisture nutrients affects spatial distribution plant communities. Plants that grow next mound known benefit from provided water storage. The other way around, protection against erosion cooling effects on microclimate mounds imposed by trees have been described. However, little is regarding influence tree parameters long‐term colony development. an interval 12 yr, we studied all Macrotermes michaelseni occurring within one square kilometer Namibian thornbush savanna in terms morphology, life history, plants, with a focus role which directly adjacent mounds. Here, present results combined analysis character states recorded at trees. More than 50% 345 were tree. Mounds showed increased activity, growth, height. Mound growth study period was correlated positively canopy coverage tree, while total heights non‐linear medium about 40%. covering sun's average zenith (north) taller, grew most more likely be active those no northern coverage. evergreen Boscia albitrunca attained highest height (195.06 ± 11.76 cm). We conclude vital like size, activity colonies facilitated shading These benefits shown take significant effect span yr. This indicates proper mutualism, not loose alliance obligative eu‐symbiosis. Therefore, propose use term “partner tree” for M.
