Dwarf Bulrush Conservation Project

Little big dwarf!
The dwarf bulrush (Typha minima) is a typical pioneer species of alpine floodplains and prefers to settle in freshly created backwaters with silty-sand deposits. These areas  are always found away  from the main channel. 

River engineering over  the last 100 years has caused the decline of this species in Europe and  they are now even included  in the red list as being acutely endangered. Today the remaining populations in the Alps are mostly isolated and in some parts their numbers have already fallen well below the critical population size. Which is  why assisting measures are required to secure the survival of the dwarf bulrush.
Incidentally, the  Tiroler Lech Nature Park is home for the largest dwarf bulrush population in the Alps.

For many years now  a species conservation programme for  endangered plant species has been carried out in the Tiroler Lech Nature Park:


  1. examination of the population situation and an endangerment analysis for the dwarf bulrush in North Tirol;
  2. strengthening  this subpopulation within the Nature 2000 area with suitable biotope development measures and  establishing  a breeding  pool from which indigenous plants (achenes, seedlings) can be taken for the Lech and other Tirolean rivers to enforce rewilding measures in the future.
  3. biotope conservation and development of recent subpopulations
  4. installing a preservation culture in the Botanical Gardens in Innsbruck  to save  genetic material and for resettlement measures
  5. replanting  seedlings and freshly harvested achenes to accompany rehabilitation measures  in the Tiroler Lech Nature Park
  6. efficiency checks on f the resettlement attempts
  7. development of targets for conserving the species and its habitat in the long term


This species conservation project is scientifically prepared and monitored  by Prof. Dr. Norbert Müller from the  Fachhochschule Erfurt, a specialist in field landscape grooming and biotope development, and also by Prof. Mag. Dr. Konrad Pagitz from the University of Innsbruck.
