Secondary succession in sandy old‐fields: a promising example of spontaneous grassland recovery

QUESTION: Based on the spontaneous vegetation development of old‐fields in the Nyírség and Kiskunság sand regions (Hungary), we aimed to answer the following questions using the chronosequence method: (1) how do the proportions of different functional groups change during succession; (2) which target species establish successfully in the old‐fields during the course of succession; and (3) how successful is spontaneous succession in the recovery of target grasslands? LOCATION: Two sand regions of the Great Hungarian Plain: (1) the Nyírség sand region (East Hungary, acidic sand, moderately continental climate) and the Kiskunság (Central Hungary, calcareous sand, continental climate). METHODS: Altogether 24 old‐fields were classified into young (
