Central European lichen Scots pine forests (91T0) are valuable habitats protected within the European Union. The condition of these habitats is continuously declining across Europe; consequently, active restoration measures are being proposed and assessed. Previous research established forest thinning as a standard treatment that promotes ground lichen cover by reducing tree density and increasing light availability. One additional secondary treatment suggested is litter raking, aimed at removing fine organic debris and preventing ground lichens from being replaced by bryophytes. However, litter manipulation is known to impact fungal sporocarp expression and community composition. To determine whether the standard (thinning) and combined (thinning + raking) treatments differently affect macrofungal communities in 91T0 habitats, we established 24 monitoring plots in lichen-dominated (L) and degraded, bryophyte-dominated (B) 91T0 forest areas subjected to the two restoration regimes. We recorded macrofungi data over five years following treatment. In L sites, macrofungal communities were similar regardless of treatment. In B sites, communities differed between treatments; the combined treatment resulted in communities more similar to those in L sites. We suggest that these patterns in macrofungal diversity can serve as an indicator of habitat restoration success, and that the combined treatment is the more effective approach for restoring bryophyte-dominated lichen forests. Compared to other organisms, fungi are relatively overlooked in conservation research and legislation. However, our study highlights their potential as indicators of habitat condition and demonstrates how fungal monitoring can be incorporated into habitat assessment processes.
