“…This Spanish region, located in the south of the Iberian Peninsula, covers 87,597 km 2 with 8.5 million inhabitants. Andalusia is a major biodiversity hotspot in the Mediterranean region (Estrada et al, 2011;López-López et al, 2011;Moreno Saiz, 2003). The floristic richness of vascular plants in Andalusia has been estimated as c. 4000 species, 436 of which are considered endemic.…”

“…As proposed by Moreno Saiz et al (2003), the systematics and chorology of rare plants should be reviewed periodically, especially of those posing taxonomic problems. Antirrhinum lopesianum certainly falls under this heading (Webb, 1972;Sainz Ollero & Hernández Bermejo, 1981).…”

Antirrhinum lopesianum Rothm. is a narrow endemic of the Lusitan Duriensean biogeographical sector (central western Spain and north-eastern Portugal). The species is listed as threatened in several Spanish documents, although it does not figure as such in any Portuguese document. This paper provides a detailed study of its distribution, estimates of the sizes of its populations, the threats it faces, and its current conservation status. The total number of individuals thought to exist is only 768, distributed along the valley of the River Duero on the Spanish -Portuguese border (562, 71.2%), and in the Portuguese Sabor River valley (206, 26.8%). The main threat to the species is loss of habitat: about one third of the Iberian populations can be considered threatened; one population containing 37.6% of all these plants (289) is severely threatened. To determine the Area of Occupancy and the Extent of Occurrence, an exhaustive bibliographical survey was carried out, and herbarium specimens deposited in several institutions were revised. It is, therefore, classifiable as Critically Endangered in Portugal and Endangered in Spain.

“…This wide scale survey produced a database of threatened plants in Spain. Among other conservation information, the number of occupied 1 9 1 km 2 UTM grid quadrats for each population was recorded, accounting for 2571 quadrats in total (Moreno Saiz et al 2003). We used those populations of plants to calculate species area of occupancy.…”

“…This will probably produce an increase in skewness for this inventory in the near future. Overestimation is related to the way Red Data surveys are conceptually conceived and Biodivers Conserv (2012) 21:1937-19511947 designed in high diversity areas under high human pressures as in the Spanish case (Moreno Saiz et al 2003). Botanists are highly focused on detecting as many of the smaller populations in an endangered flora as possible, often devoting less time to completely covering the potential habitat of the plant.…”

How plant inventories improve future monitoring

Plant inventories are at the heart of conservation efforts. Despite their obvious conservation values, properties of these datasets are poorly understood. We use plant databases from three different well-established inventories [rare plants in California (CA), Spanish threatened plants (SP) and the Proteaceae in South Africa (SA)] to explore the behavior of large data sets in facilitating the link between current field surveys and future standardized monitoring methods. We analyze area frequency curves of the species area size for each data set and for a series of extracted databases from each inventory. Our results show that all field surveys produced left-skewed frequency distributions. A lognormal distribution is better fitted by SA, followed by CA and finally by SP, which is least suited to a lognormal fit. Using the most threatened portion of the three floras, these general patterns still apply. Secondly, a minimum sample analysis indicates that precision increases according to sample size. Proportionally, CA data require less sampling effort than the Spanish pool and the latter require less than do SA in order to get a clear monitoring trend. Larger skewness values are related to inventories with wider scope. SA Proteas display the most skewed distribution. Skewness in California may be explained not only by the nature and scope of the inventory but also by the scale used for mapping. The Spanish database is also affected by surveyor bias towards the most endangered portion of the data set. Monitoring should take into account the original nature of each inventory. Particular inventory methods and scope may produce different outputs, constraining future monitoring programs. Key aspects are skewness and variation, and both combined could identify inventories in need of better data collection practices for more precise estimates of changes in biodiversity.
