Mohamed bin Zayed Species project number 180519099

Distribution and Red List Assessment of the restricted range endemic Jacobaea mouterdei (Asteraceae)

Mohamed bin Zayed Species Conservation (Project No. 180519099) - Mouterde's ragwort - Awarded $4,500 on November 01, 2018

Jacobaea mouterdei (Arènes) Greuter & B.Nord, previously Senecio mouterdei Arènes, is a steno-endemic (restricted range endemic) plant species of Mount Lebanon. It is known to occur exclusively in the mountains of the districts of Danniye and Akkar, in North Lebanon. The species belongs to the Asteraceae family (Composites).

The species was first collected and described in 1946. Since then, no collector ever reported the presence of this species anywhere in Lebanon, until 2009 when two collectors rediscovered the species in the same area. 


This project aims to collect data about this poorly known species:

-Extensive fieldwork to be carried out in the different branches of the “Valleys of Hell” and their surroundings to collect data about Jacobaea mouterdei. Exploration will allow to locate and georeference the individuals in the area. Spatial analysis will be performed with a Geographic Information Systems (GIS) to calculate the geographic range of the species . The goal is to clearly define and map the distribution of Jacobaea mouterdei. Data about the biology of the species, its natural habitats, population size and specific threats will also be collected

-The recent accurate data about its ecology, geographic distribution, population size, trends, and specific threats will allow to assess the vulnerability of the species and estimate its conservation status using the guidelines and criteria of the International Union for Conservation of Nature (IUCN).

-An action plan for the preservation of Jacobaea mouterdei should be developed and include a summary of all information available in order to propose conservation actions that could ensure the survival of the species, such as the identification of appropriate choices of potential sites for in-situ conservation.



The fieldwork took place from April to November 2019 (see report and draft of IUCN assessment of Jacobaea mouterdei attached).

This project received a co-funding from the Global Biodiversity Information Facility (GBIF) in April 2019 to allow the mobilization and publishing of the data collected (BIFA4_053).

Here a link to video that was made by Zoé Filloux about the fieldwork carried out in Lebanon during 2019 to survey Jacobaea mouterdei. The video was realised in October 2019:
