Zusammenfassung:Termite restore plant diversity and soil on altered lands in West Africa with particular abundance of small mound made by Trinervitermes trinervitus , Trinervitermes geminatus , Cubitermes spp. or Microcerotermes spp. The particular abundance of small mounds on altered lands suggests the existence of underlying abiotic and biotic factors. This study investigated the spatial patterns of termite mounds on the altered lands and its relationship with tree distribution in order to sustain the ecological restoration of the altered lands. Thus, unmanned aerial vehicle (UAV) was used to collect images on three different altered land sites of 18 ha characterised with termite mounds. The images were ortho‐mosaicked with Pix4D Mapper software. Termite mounds and trees were digitalised on these images in ArcGIS software. The Ripley's pair correlation function using spatstat package was applied to assess the spatial pattern and association of mounds and trees. An aggregative pattern (g( r ) > 1) was revealed in the spatial distribution of both termite mounds and trees across all sites. Furthermore, a positive clustered association between termite mounds and trees was noted at two study sites, likely due to the absence of human disturbance. Therefore, this interaction should be vital for assisted ecological restoration and can be factored into efforts to accelerate the restoration of soils and plants on degraded lands. The authors then recommend future research to explore the specific role this attractive relationship plays in ecosystem restoration.
