Status of Acer lobelii conservation in Europe
There is little research on Lobel's maple and almost no published empirical data currently exists specifically on the species’ population genetics. What research does exist suggests a high degree of polymorphism and that most genetic variation occurring within populations rather than between them (Guarino et al., 2008). Much of the genetic knowledge on Lobel's maple is inferred from studies on other Acer species. Lobel's maple is clearly genetically distinguished from Norway maple (Acer platanoides) and Miyabe maple (Acer miyabei) (Grim and Denk, 2014)
Lobel's maple pollen is wind dispersed and seeds are dispersed by wind or animal activity. This facilitates connectivity among subpopulations, promotes high within-population diversity, and lowers interpopulation differentiation in the absence of geographically isolated populations (Guarino et al., 2008).
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2025.
Typically, other Acer species in fragmented habitats display moderate to low differentiation among populations (Guarino et al., 2008). Given Lobel's maple’s small range of fragmented habitats it might be expected that the species has undergone some reduction in gene flow among isolated clusters, leading to subtle genetic structuring (Guarino et al., 2008). However, this fragmentation and isolation have not been to a degree sufficient to cause severe inbreeding or loss of diversity, despite a weak to moderate genetic structuring of the species where isolated populations exist (Guarino et al., 2008).
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2025.
Due to its limited range and habitat threats, conservation of the species is needed. However, a lack of research makes it unclear what management of the species would be beneficial. Therefore, further research on the species and its genetics is required.
