Providence and Research

Conservation of genetic diversity and protection of the genetic ressources in the forests of Bavaria are the principle targets of the ASP. The genetic diversity is the basis for adaptability and survival of our tree species under changing environmental conditions. It is the crucial factor for stability and yield of forest ecosystems.

Forest ecosystems are exposed to numerous human influences. Parcelling out and destruction of habitats, changes and stress on the environment, dislocation of populations as well as forest management itself influence the genetic networks and subsequently the forest ecosystem. Long term influences on the genetic structures and their development in space and time in the forest are focussed by the applied research of ASP.

Modern methods of investigation like DNA - and Isozyme analyses allow for a closer look into the composition of the hereditary make up of forest trees and tree populations, genetic inventories and longterm monitoring in the forests of Bavaria.

ASP is tending a net of field trials throughout Bavaria on which various species and provenances are studied for their suitability under different climatic and edaphic conditions.

Regenerative ressources are gaining importance in the light of the limited supply of fossil fuels. Thus research also concentrates on fast growing tree species for energy forests. Poplars and willows are tested in field trials, suitable clones are selected and managed in clone banks.

ASP also concentrates on securing the identity of forest reproductive material and provenance recommnedations for forest owners which are both indispensable for sustainable forest management. This work includes the long term conservation of seed lots of selected stands in the Bavarian Forest Gene Bank and the supervision of Seed Orchard Programme.

Commercialisation of forest reproductive material is governed by the Federal Law on Forest Reproductive Material. The reinforcement for Bavaria has been assigned to the ASP.

Assignments to ASP

Overall target: sustainable management of forest genetic ressources in Bavaria

Applied research in forst genetics

ASP carries out research on behalf of the Bavarian State Ministry of Agriculture and Forests and cooperates in national and international projects.
  • Inventories of the genetic variation of tree species and resulting provenance recommendations for Bavaria
  • Genetic investigations determining species and provenance
  • Studies on the effects of silviculure on the genetic composition of tree populations
  • Provenance and progeny trials
  • Tests of introduced species regarding their suitability for Bavaria
  • Clonal tests on fast growing species
  • Genetic monitoring
  • Cheques of the identity of forest reproductive material

"Designated Authority for Forest Reproductive Material in Bavaria"

As of 01.July 2006 ASP has been assigned "Designated Authority in Bavaria" according to the Law on Forest Reproductive Material. The task involves:
  • Selection and registration of basic material
  • Operating the National Register for Basic Material - Bavaria ( ca. 75,000 ha)
  • Inspection of registered seed and nursery companies
  • Controll the trade of forest reproductive material
  • Develop provenance recommendations

Conservation of forest genetic ressources in Bavaria

  • Seed orchard programme
  • Forest gene bank
  • Regeneration of rare and endangered species of trees and shrubs
  • Selection of forest gene reserves

Transfer of knowledge

In addition to the above mentioned activities transfer of the resulting knowledge has high priority. The transfer is achieved by formal courses for universities and technical institutes , training of international stipends and extension for practicing foresters and local school classes.


Within the frame of its assignments ASP cooperates with other research institutions and is member in various bodies dealing with forest gene conservation and forest reproductive material, both, national and international.

Services and Consulting

  • Forest seed testing
  • Genetic plausibility cheques for controls
  • Energy forests and introduced species

ASP's Birthday

After the rediscovery of Gregor Mendel's hereditary laws by Tschermak and de Vries in 1900 the subsequently booming knowledge in genetics was soon recognized by foresters. Yet, it was not before the Mid Fifties, that Professor Rohmeder could head the first Institute of Forest Genetics and Forest Tree Breeding at the University of Munich.

In order to warrant the timely and comprehensive implementation of genetic findings in practical forestry the Bavarian State Institution for Forest Seeding and Planting was founded in Teisendorf in 1964. The state owned seed extraction plants and nurseries at Laufen and Bindlach were incorporated as operational arms.

1991 an isozyme lab was added. In 1997 the seed testing lab was incorporated and in 2002 a DNA lab completed the set of instruments.

Following the Forest Reform in Bavaria in 2005 the operational parts were shifted to the newly established Bavarian State Forests - BaySF, while the duties of the "Designated Authority for Forest Reproductive Material" were concentrated at the ASP.
