“…A recent red‐listing initiative for about 2400 taxa (including vascular and nonvascular plants and lichens) highlights that 24.3% of assessed taxa are listed under one of the International Union for Conservation of Nature threat categories (i.e., vulnerable, endangered, or critically endangered) (Orsenigo et al., 2021); 22.4% of the threatened taxa are endemic to Italy (Orsenigo et al., 2018); and 54 taxa are extinct or possibly extinct in the wild (Orsenigo et al., 2021). Moreover, the IV Italian report on the conservation status of the 115 Italian plants listed in the European Union Habitats Directive (92/43/EEC) shows that 54% are in an “unfavourable–inadequate” or “unfavourable–bad” status (Fenu et al., 2021). Overall, a considerable proportion of Italian flora requires conservation action, and translocations represent an effective tool to halt or reduce the risk of extinction of threatened plant species.…”

Conservation translocations are becoming common conservation practice, so there is an increasing need of understanding the drivers of plant translocation performance through reviews of cases at global and regional levels. The establishment of the Italian Database of Plant Translocation (IDPlanT) provides the opportunity to review the techniques used in 186 plant translocation cases performed in the last fifty years in the heart of the Mediterranean Biodiversity Hotspot. In this study, we describe techniques and information available in IDPlantT and use these data to identify drivers of translocation outcomes. To this end, we tested the effect of 15 variables on survival translocated propagules at the last monitoring date, using binomial logistic Mixed Effect Models. The analysis revealed that 11 variables significantly affected survival of transplants, namely: life form, site protection, material source, number of source populations, propagation methods, propagule life stage, planting methods, habitat suitability assessment, site preparation, aftercare and costs. Plant translocations in Italy and in the Mediterranean area should consider the complexity of speciation, gene flow and plant migrations that has led to local adaptations with important implications on the choice and constitution of source material. The integration of vegetation studies for the selection of suitable planting sites can significantly increase the success of translocation efforts. Whilst post‐translocation watering has a general positive effects on traslocation outcome, other aftercare techniques do not always increase transplant survival. Finally, we found that how funds are spent appears to be more important than their actual amount.This article is protected by copyright. All rights reserved

“…& Byng (basionym: Centranthus amazonum Fridl. & A. Raynal; Fridlender & Raynal-Roques, 1998), of Sardinia, was included in Annex II of the EU Habitats Directive 92/43/EEC as a species of conservation value for which monitoring and in situ conservation are required (Fenu et al, 2021). Valeriana amazonum (Plate 1) is perennial, with glaucous stems and leaves.…”

Threatened or poorly known? The case of the Mediterranean narrow endemic Valeriana amazonum in Sardinia

The Mediterranean flora is characterized by a high number of narrow endemic plant species that are often restricted to a few small populations. One of these species, Valeriana amazonum, a perennial plant occurring only in the Supramontes region of central eastern Sardinia, is categorized as Critically Endangered on the IUCN Red List because of its restricted range, small population size and an inferred decline caused by several threats. During 2007–2022, we monitored all mature individuals of this plant annually and surveyed ecologically suitable sites for the species. We identified two previously unknown populations and also learnt of two successful translocations carried out independently by an unknown local citizen. As our monitoring data indicate there has been no decline in the number of mature individuals over the period of monitoring, the species’ conservation status requires reassessment. We recommend that V. amazonum should be recategorized as Near Threatened as it seems to be poorly known rather than highly threatened. This could also be the case with other narrow Mediterranean endemics, especially those that grow in inaccessible habitats for which long-term studies are needed to assess conservation status.

The European Habitats Directive was adopted to halt the rapid loss of biodiversity and has become an important instrument for protecting biodiversity in the European Union. Three aquatic plant species protected under the European Habitats Directive have so far been found in Lithuania: Aldrovanda vesiculosa, Caldesia parnassifolia, and Najas flexilis. Our aim in this study was to evaluate the former and current distribution and the status of conservation of the target species. Screening for the above-mentioned protected aquatic plant species was performed in 73 natural lakes throughout Lithuania in 2019–2021. We confirmed extant populations of Aldrovanda vesiculosa in four lakes, Caldesia parnassifolia in two lakes, and Najas flexilis in four lakes in the northeastern part of the country. We studied Aldrovanda vesiculosa populations three times (2015, 2019, and 2022) in Lake Rūžas and once each in Lake Apvardai and Lake Dysnai (2020). The population density of Aldrovanda vesiculosa ranged from 193.4 ± 159.7 to 224.0 ± 211.0 individuals/m2, the mean length of plants ranged from 12.5 ± 2.1 to 14.3 ± 2.7 cm, and the mean number of apices ranged from 2.0 ± 0.7 to 2.2 ± 0.9 per individual. The habitat of Aldrovanda vesiculosa in Lake Rūžas covered an area of about 3 ha. The number of generative individuals of Caldesia parnassifolia widely varied between years in Lake Rūžas. All populations of Najas flexilis were small, although the potential habitats in the studied lakes cover relatively large areas. We propose designating all lakes with populations of Aldrovanda vesiculosa, Caldesia parnassifolia, and Najas flexilis as special areas of conservation, as well as developing and implementing action plans for the conservation of these species and their habitats.
