Will they be back? A framework to guide rare macrophyte conservation decisions in lakes

Restoration Ecology, Volume 32, Issue 1, January 2024.
Shallow lake restoration typically focusses on the re‐establishment of macrophytes. The likelihood of a species returning to a site is contingent on dispersal, proximity to propagule sources, and the on‐site propagule‐bank viability. We explore the potential of palaeoecological records in combination with botanical surveys and distribution maps, to ...
