Poster Information
Abstract: Intensive farming practices may cause severe habitat fragmentation and isolation of populations. We investigate how the landscape structure and habitat conditions affect the populations of the short-lived, non-clonal Salvia nemorosa, in Hungary.
In a pilot study conducted in 2021, we targeted nine populations of the Great Hungarian Plain, of which, seven on kurgans (ancient burial mounds) and two on flat areas. We set up permanent plots for demographic observations, in which we censused the presence and traits of 356 plants in total.
Heat load had a positive, significant effect on plant density, a negative, significant effect on leaf area, and it did not affect the number of plant stems or inflorescence length. We did not find any effect of habitat area on the tested variables.
These preliminary results suggest that local habitat quality may be a critical driver of trait variability and persistence of short-lived plants in severely fragmented landscapes.
