État de la populationTexte officiel évaluation IUCNExpert

Alnus acuminata is a widespread montane species. It is more common in the higher elevations of Guatemala and Costa Rica than lower elevations of other Central American countries. However, no estimates on population size or trends are available.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Although a number of pests and pathogens are reported to affect this species, no significant threats are currently documented that would threaten this species across its whole range, neither are large threats predicted in the foreseeable future.

A stem borer (Scolytodes alni) has been reported to affect populations of Alnus acuminata in Costa Rica during the dry season which can cause serious damage to trees, but outbreaks are sporadic, mainly within plantations, and can be eliminated by burning infected material. The species is also susceptible to attack by defoliators (Nodonota irazuensis and Nodonota ca. parvula). Vertebrates such as Sciurus sp. may cause debarking and Sylvilagus brasiliensis may destroy seedlings. Fungi such as Fusarium sp. and Trichoderma sp. may damage seeds; Colletotrichum sp. and Phomopsis sp. may affect leaves; and Rosellinia sp. may affect stems and roots in mature trees. Harvesting from wild populations also occurs.
