Status of Acer trautvetteri conservation in Europe
Maple (Acer) as a group has undergone many radiations into different species, with many within the group being very similar genetically (Grimm, Denk, and Hemleben, 2007). Research supports the distinction of red-bud maple from other maple species, at least morphologically, despite its genetic similarity to other maple species such as Heldreich’s maple (Acer heldreichii) and velvet maple (Acer velutinum Boiss.) (Grimm, Denk, and Hemleben, 2007). This genetic similarity suggests historical reticulation/horizontal gene flow among related taxa within Eurasia (Grimm, Denk, and Hemleben, 2007), although the restricted native range of the species would be expected to have affected its genetic structuring and differentiation (Yilmaz, 2007).
There have been no studies specifically on molecular markers or the genetic diversity of red-bud maple. General studies of the genetics of maple that include red-bud maple indicate it has a standard chromosome number and ploidy level typical for maples and a genome size within the lower to mid-range for maples (Renner et al., 2008). These factors can affect genetic diversity and differentiation and ecological adaptability of the species but are not direct measures of genetic diversity per se. Thus, further research on the genetic diversity of red-bud maple is needed.

N/A
The bibliographic review was conducted by James Chaplin of the EUFORGEN Secretariat in August 2025.
There are no clear, dedicated population-genetics studies specifically on red-bud maple in the mainstream literature. This lack of data makes it difficult to determine whether the species’ genetic diversity is under threat from genetic erosion, reduced connectivity, or population isolation. Without such information, it is not possible to assess the severity of threats to its genetic diversity.
Given the lack of studies, further research is needed before it can be determined what management strategies may be needed to conserve the genetic diversity of red-bud maple. Any future conservation actions would need to be informed by baseline genetic diversity and population structure data.
