The basic goal in the conservation of vegetation is to rescue
and display all the extant vestiges of the camp. Exceptionally
salient aspects include maintaining the special arrangement of
trees that was used to camouflage the mass killing facilities,
in the form of green rows and groups of trees, and even woods.
The conservation of vegetation at the site involves work
including • care for trees and bushes, including historically
valuable trees • care for grassy areas • weed removal. In total,
the boundaries of the Museum include an area of 191 hectares
9724 m², of which 171 hectares 6146m² comprise the Birkenau
site, and 20 hectares 3588m² the Auschwitz I site. The great
extent of the grounds means that work is carried out by both
Museum employees and outside companies.
