In this study, we investigate how specific micro interaction structures(motifs) affect the occurrence of tipping cascades on networks of stylizedtipping elements. We compare the properties of cascades in Erd\"os-R\'enyinetworks and an exemplary moisture recycling network of the Amazon rainforest.Within these networks, decisive small-scale motifs are the feed forward loop,the secondary feed forward loop, the zero loop and the neighboring loop.  Of all motifs, the feed forward loop motif stands out in tipping cascadessince it decreases the critical coupling strength necessary to initiate acascade more than the other motifs. We find that for this motif, the reductionof critical coupling strength is 11% less than the critical coupling of a pairof tipping elements. For highly connected networks, our analysis reveals thatcoupled feed forward loops coincide with a strong 90% decrease of the criticalcoupling strength.  For the highly clustered moisture recycling network in the Amazon, we observeregions of very high motif occurrence for each of the four investigated motifssuggesting that these regions are more vulnerable. The occurrence of motifs isfound to be one order of magnitude higher than in a random Erd\"os-R\'enyinetwork.  This emphasizes the importance of local interaction structures for theemergence of global cascades and the stability of the network as a whole.
