Research Arboretum Großpösna

What is an Arboretum?

Arboretum: is derived from the Latin word "arbor" (Latin for tree.) or "Arbustum" (Latin for tree planting.) so the term Arboretum very aptly describes, what is behind it: a tree or woody plant collection for study purposes. The arboretum serves two functions: science and environmental education. The arboretum provides the unique opportunity to investigate diversity effects of 100 woody species in one single area under the same environmental conditions. And it also allows the perception of morphological, anatomical and physiological differences between various species for pupils, students and other interested persons.

The full area of the ResearchArboretum is fenced but open for visitors and can be reached through a path from the Botanical Garden Großpösna. Formerly the 2.5ha were extensively used cropland but later included in the Botanical Garden where it was used as Officinal-Garden (still recognizable during flowering season of highly diverse herbaceous plants). Mean annual temperature is 9.8°C and mean annual precipitation is 556.9 mm, main wind direction is southwest. The Arboretum is designed for 100 woody species. The selection of species was carried out according to their ecological and economic value for European forests. The Arboretum was funded by University of Leipzig, the EU-Project FunDivEurope (Seventh Framework Program) and the German Center for Integrative Biodiversity Research Halle-Jena-Leipzig iDiv.

Planting and care of trees is mainly done by the gardeners of the Botanical Garden of the University of Leipzig.

Arboretum

  • long term plantation (established 2012-2014)
  • 100 tree species with 5 individuals in 5 blocks
  • random position of species within the block
  • distance of 5.8m between and within the rows
  • mowing the lawn 2x / year,
  • watering during prolonged drought in the initial phase

Plantation

  • short term plantation (established 2012)
  • for destructive measurements and partly as a "reserve"
  • 78 tree species
  • random position of species
  • distance of 1.0m between and within the rows
  • water-permeable foils to exclude additional grassland competition

Projects using the Plantation

  • PhD thesis Benjamin Dechant (UFZ)
  • Bachelor thesis Anja Wieprecht: "Comparative analysis of morphological and chemical bud traits of tree saplings relevant to assess palatability of saplings for mammalian herbivores"
  • PhD thesis Bettina Ohse: Project FunBrowse
