Spatial patterns and species coexistence in mixed Abies marocana-Cedrus atlantica forest in Talassemtane National Park

•N Africa mixed Moroccan fir-Atlas cedar forests are relevant biodiversity hotspots.•Tree spatial patterns suggest dynamic stability in these forests arisen by:•(i) Niche-segregation processes among the two species, and.•(ii) Facilitative effects from initial cedar colonization to late-successional fir stands.•Adaptive management based on cedar establishment may promote fir conservation.
