In an experimental set-up, European beech (Fagus sylvatica L.) saplings were subjected to two consecutive water-withholding treatments during the 2022 growing season, resulting in five drought-severity categories. We monitored these categories over the following three years to assess drought legacy effects on phenology and growth. In the first post-drought year, bud burst proceeded more slowly in all drought categories, with the plants exposed to severe summer drought displaying the longest duration. Minor differences between drought categories and control plants were observed in timing of autumn leaf senescence in the first post-drought year and in the following bud burst, suggesting recovery in these phenological responses. Unexpectedly, differences re-emerged in autumn leaf senescence in the second post-drought year, when all drought categories displayed delayed senescence. This differentiation persisted into the following spring, with delayed bud burst in the severe spring- and summer-drought categories. The severe spring-drought categories maintained delayed senescence in the third post-drought year. Diameter and height growth were strongly reduced in the first year following drought. Although growth differences largely disappeared in the second post-drought year, the severe summer-drought categories exhibited enhanced diameter growth in the third year, indicating compensatory growth. Together, these results demonstrate that drought legacy effects in F. sylvatica are dynamically expressed over multiple years, and that such temporal variability complicates predictions of long-term forest responses to increasingly frequent episodic drought events under climate change.<\/jats:p>","DOI":"10.3390\/plants15182867","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T11:05:53Z","timestamp":1789988753000},"page":"2867","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Re-Appearing Legacy Effect in Timing of Autumnal Leaf Senescence and Compensation Growth After Severe Drought in Fagus sylvatica L."],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1687-8152","authenticated-orcid":false,"given":"Kristine","family":"Vander Mijnsbrugge","sequence":"first","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofie","family":"Vanneste","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0396-6614","authenticated-orcid":false,"given":"Sharmila","family":"Majumder","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Schouppe","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefaan","family":"Moreels","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Moreels","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4590-9610","authenticated-orcid":false,"given":"Simeon","family":"Beeckman","sequence":"additional","affiliation":[{"name":"Department for Forest Ecology and Management, Research Institute for Nature and Forest (INBO), 9500 Geraardsbergen, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"660","DOI":"10.1016\/j.foreco.2009.09.001","article-title":"A Global Overview of Drought and Heat-Induced Tree Mortality Reveals Emerging Climate Change Risks for Forests","volume":"259","author":"Allen","year":"2010","journal-title":"For.
