1. 26. Floristic change in the province of Scania in southernmost Sweden 1800-2020: using fragmented data to study landscape-level shifts

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Cassandra Hallman; [2020]
   Keywords : Biology and Life Sciences;

   Abstract : Vascular plant observances were compiled for 10 well-documented parishes throughout southernmost Sweden from published floras, herbarium specimens, modern inventories, and a large citizen-science database to provide presence/absence of species from 1800-2020 at the decade level. A regionally-specific database of species-specific plant traits and ecological indicator values was used to examine floristic and ecological changes across an extended timeline which indicates that several of the most apparent conservation issues including climate warming, woody encroachment, and soil chemistry alterations have acted for long over a century.
