Leptopelis yaldeni occurs in montane grasslands and moderately degraded habitats such as rural settlements at elevations of above sea level. Breeding typically takes place close to the banks of small streams. Males call from exposed positions; if tall vegetation is available, they will often choose to call from elevated positions, but they may also call from on the ground if the pool margin is bare earth. The eggs are deposited in nests on land near the water, and the tadpoles develop in the water.
