Boerhavia repens está incluida en el Catálogo Valenciano de Especies de Flora Amenazadas de la Comunidad Valenciana (Orden 6/2013) en la categoría “En peligro de Extinción”. La única población española conocida está localizada en Teulada (Alicante, España), siendo la segunda población conocida en toda Europa. La población alicantina desapareció en 2012, y hasta el momento se han realizado 10 plantaciones en la provincia de Alicante. De un total de 615 plantas introducidas se ha registrado una tasa de supervivencia del 8,7% (54 plantas) en el último censo. Diferentes trabajos con la germinación de las semillas y cultivo de esta planta han sido realizados en el CIEF. Boerhavia repens is included in the Valencian Catalogue of Threatened Species of the Valencian Community (Order 6/2013) in the category “In danger of extinction”. The only known Spanish population is located in Teulada (Alicante, Spain), being the second known population in Europe. This population disappeared in 2012, and so far 10 plantations have been made in the province of Alicante. A total amount of 615 plants were translocated and a survival rate of 8,7% (54 plants) was observed in the latest census. Different works with the germination of seeds and cultivation of plants have been carried out at CIEF.

espanolNarcissus perezlarae esta incluido en el Catalogo Valenciano de Especies de Flora Amenazadas de la Comunidad Valenciana (Orden 6/2013) en la categoria "En peligro de extincion". Estudios recientes han demostrado su origen hibrido (= N. cavanillesii × N. miniatus [= N. serotinus auct.]). Por otro lado, el mayor especialista y monografia del genero reclamo recientemente su autonomia como especie independiente, como N. piifontianus. Esta especie es endemica de la peninsula Iberica, presente en Alto Alentejo (Portugal), Sevilla y Cadiz (Espana), y en la parte oriental de la Cordillera Betica, entre Alicante y Valencia. Sin embargo, si se tratara como una especie independiente, seria un endemismo exclusivamente restringido a la Comunidad Valenciana. Siete poblaciones naturales han sido monitoreadas, cuyos datos censales oscilan anualmente. El ultimo censo contiene 1.634 plantas. Desde 2010, se han llevado a cabo cinco experiencias de translocacion en la provincia de Alicante. De un total de 8.970 ejemplares introducidos se ha registrado una tasa de supervivencia del 28,4% (2.545 plantas) en el ultimo censo. Las poblaciones recien creadas aumentan el numero de localidades conocidas de la especie en la Comunidad Valenciana y amplian considerablemente su distribucion a lo largo del territorio. EnglishNarcissus perezlarae is included in the Valencian Catalogue of Threatened Species of the Valencian Community (Order 6/2013) in the category "In danger of extinction". Recent studies have demonstrated its hybridogenic origin (= N. cavanillesii × N. miniatus [= N. serotinus auct.]). On the other hand, the greatest specialist and monograph of the genus has most recently claimed its autonomy as an independent species, as N. piifontianus. This species is endemic to the Iberian Peninsula, present in Alto Alentejo (Portugal), Sevilla and Cadiz (Spain), and in the eastern part of the Baetic Mountains, between Alicante and Valencia. However, if treated as an independent species, it would be an endemism exclusively restricted to the Valencian Community. Seven natural populations have been monitored, whose census data oscillate annually. The latest census contains 1634 plants. Since 2010, five translocation experiences have been carried out in Alicante province. A total amount of 8,970 plants were translocated and a survival rate of 28,4% (2,545 plants) was observed in the latest census. The newly created populations increase the number of known locations of the species in the Valencian Community and considerably expand their distribution range along the territory.

Cotoneaster granatensis (Rosaceae) is an endangered species in the Valencian Community with two natural populations known and 37 wild plants located in Alicante province. The strategy applied for conservation of this species comprises three steps in a cyclical method: in situ (first step) - ex situ - in situ (second step). Current conservation status for this species has been evaluated as a part of the first step in situ actions. Ex situ conservation activities consisted of germplasm conservation on seed banks, creation and maintenance of collections of livings plants and production of new plants in order to develop reintroductions (in situ actions: second step) in natural populations. The seed germination is a complex issue, but an effective protocol has been established reaching values over 60% of germination. The plant propagation by cuttings has not been successful. In situ actions such as reducing the threat of herbivory has been also essential to enhance natural populations. The initial results on plantations in the natural habitat show high survival rates of specimens.

In order to preserve endangered plant populations and recover their evolutionary potential and ecological behavior, some restoration measures generally involve the reinforcement of the population size in existing natural populations or the reintroduction of new populations. Genetic monitoring of both natural and restored populations can provide an assessment of restoration protocol success in establishing populations that maintain levels of genetic diversity similar to those in natural populations. The highly threatened Spanish species Silene hifacensis (Caryophyllaceae) has only three natural reduced mainland populations in the Iberian Peninsula, following decline and extinction that occurred during the late 20th century. Preterit restoration strategies were essentially based on the implantation of new populations and reinforcement of certain existing populations using transplants mostly cultivated in greenhouses. In the present contribution, levels and patterns of genetic variability within natural and restored populations of Silene hifacensis were assessed using the molecular technique AFLP. Our results pointed out significant genetic diversity differences across the three existing natural populations though their population fragmentation and progressive loss of individuals have not had an impact on the global genetic diversity of this species. For restored populations, their levels of genetic diversity were similar and even higher than in natural populations. As a result, the past restoration protocols were successful in capturing similar and even higher levels of genetic diversity than those observed within natural pools. However, inbreeding processes have been detected for two restored populations. Finally, the main source of plant material for the long-time restored transplants appears to be the natural population of Cova de les Cendres. This study demonstrates, once again, how genetic markers are useful tools to be taken in consideration for endangered plant species conservation plans. Work was supported by the project CONSELLERIATERRITORIO4-06i (Conselleria de Territori i Habitage, Generalitat Valenciana).

The establishment of seed orchards has allowed obtaining a great deal of germoplasm of Silene hifacensis, an endangered endemic Ibero-Balearic species. In four years, 3.958.531 seeds have been collected in our four seed orchards from a total of 570 plants/year per average, including all genetic variability from natural populations of this species in Alicante province (Illot of Mona, the Pessebret, Cova de les Cendres, Morro de Toix).
