Topsoil removal is a restoration technique in which the uppermost soil layer is stripped away to reduce excessive nutrient levels, particularly nitrogen and phosphorus, which can hinder the re-establishment of native vegetation. This method is especially used in sites where high nutrient concentrations favor competitive species that outcompete native flora, like grasslands or heathlands. By removing this topsoil we can improve the conditions for the germination and growth of target species, promoting the recovery of natural plant communities. However, this approach can also disrupt soil fauna and microstructure. Thus, a careful consideration of potential ecological impacts and complementary measures are needed.
