Restoration of temperate forestry-drained fens brings back key species and an ecosystem function

This study shows that rewetting forestry-drained temperate fens leads to partial vegetation recovery and initial peat formation over 38 years, but vegetation quality does not fully match near-natural sites.

Long-term stomatal and leaf trait dynamics in invasive knotweeds in Europe - insights from 160 years of herbarium records

This study uses herbarium records to analyze long-term changes in stomatal and leaf traits of invasive knotweeds over 160 years, finding shifts in stomatal size and shape linked to CO2 levels and climate.

Small stream restoration increases habitat and plant diversity across scales

This study shows that restoring small streams increases habitat and plant diversity in agricultural areas by improving stream complexity and floodplain connectivity.

Advanced flowering phenology of restored grasslands

The paper compares flowering phenology between restored and reference meadows, finding restored plants flower earlier, especially early-flowering species.
