Scientific Name: Ampedus hjorti (Rye, 1905)

Assessment Information [top]

Red List Category & Criteria: Vulnerable A4c ver 3.1
Year Published: 2010
Date Assessed: 2009-06-05
Assessor(s): Pettersson, R., Hyvärinen, E., Munteanu, N., Istrate, P., Schlaghamersky, J. & Schmidl, J.
Reviewer(s): Alexander, K. & Nieto, A.
Justification:
European regional assessment: Listed as Vulnerable (VU A4c). The disappearance of old hollow oak trees across its range due to management or dying off and the prospective gap in the provision of old trees in the next 50 years severely reduces the habitat for this species. The Vulnerable assessment is precautionary based on the continuing decline of the only habitat available for this species.

EU 27 regional assessment: Listed as Vulnerable (VU A4c). The disappearance of old hollow oak trees across its range due to management or dying off and the prospective gap in the provision of old trees in the next 50 years severely reduces the habitat for this species. The Vulnerable assessment is precautionary based on the continuing decline of the only habitat available for this species.

Geographic Range [top]

Range Description:This species is recorded from Germany, Poland, Denmark, Sweden, Lithuania and Latvia (Laibner 2000). It has also been recorded in patchy distributions elsewhere across central, southern and northern Europe (Austria, Slovakia, Norway, Greece and Czech Republic). For many countries, records are missing but occurrence is probable (lack of data rather than lack of beetles). In Denmark it is distributed in Zealand and Lolland; only few localities in Jutland (National Environmental Research Institute 2007).
Countries occurrence:
Native:
Austria; Czech Republic; Denmark; Germany; Greece (Greece (mainland)); Hungary; Latvia; Lithuania; Norway; Poland; Slovakia; Sweden

Population [top]

Population:The species distribution is very scattered throughout its range as it uses mainly old hollow oak trees as habitat. It is inferred that the population trend is declining.

It is very rare in Hungary, being known from only three areas in the country; all populations are small, but it is not considered to be threatened in Hungary (O. Merkl pers. comm. 2009). In the Czech Republic it is known only from one area and in the Slovak Republic it is known from at least seven areas (Laibner 2000). In Sweden it is rare but it occurs mainly in protected areas.
Current Population Trend:Decreasing

Habitat and Ecology [top]

Habitat and Ecology:This is an obligate saproxylic species. This is a typical rot-hole dweller, developing in wood mould in cavities in trunks and stumps of old oaks Quercus in alluvial woodlands and deciduous vegetation, from foothills to highlands (Laibner 2000). In Hungary all records are from oak forests (O. Merkl pers. comm. 2009).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: Saproxylic Coleoptera tend to be popular with beetle collectors although trade is rarely an issue, the only exceptions being a few larger species of more dramatic form or colour.

Threats [top]

Major Threat(s):

The main overall threat is degradation or loss of habitat quality, especially old growth with hollow trees and loss of mega-tree continuity. Local populations can be eradicated with the removal of one hollow tree. This includes the cutting down of trees in parks or alleys or in old pastures.

Conservation Actions [top]

Conservation Actions: It is important to preserve big hollow oak trees. The species occurs in several protected areas (e.g., Hungary).
