- Observation The Numidian cypress persists in only three small, fragmented forests covering a total of 64.33 ha.
- Observation Bou Abdallah soil had higher clay content than the other sites.
- Observation Dir Satou soil had the highest levels of nitrogen, organic carbon and Olsen P among the sites.
- Observation Dir Satou soil had the highest levels of available Mn and Mo among the sites.
- Observation The climate at the sites shows a clear warming trend.
- Observation The climate shows pronounced summer droughts.
- Observation Trees showed widespread damages.
- Mechanism The tree damages are attributed to intensive grazing, tree cutting, drought-related crown dieback, and pest and pathogen attacks.

- Observation Natural regeneration was limited.
- Observation The fungal pathogen Seiridium cardinale, the cause of cypress canker, was detected on C. numidica for the first time.
- Recommendation Urgent monitoring and management of Seiridium cardinale is needed.
