General aims of the SALVERE - Project
• Practical contribution to realize the 2010-target by utilization of species-rich grasslands
as donor sites for regional seed mixtures
• Use of the harvested seed mixtures in restoration of species-poor grasslands and in
establishment of new species-rich grasslands on former arable land, road embankments,
ski slopes, in mined sites, and for compensation measures
• Quantification of the seed potential on donor sites and analysis of harvested seed
mixtures concerning species composition and number of germinable seeds
• Transfer of knowledge into practice during workshops and field trips, and by drafting of a
practical handbook for seed harvest and ecological restoration of species-rich grasslands
• Recommendations for an European quality standard for „wild“ seed mixtures

The methods
on-site threshing & green hay
On-site threshing
• Mowing and immediate threshing (“on-site”) of the material with a
thresher.
• Application rate depends on seed content and degree of purification of
threshing material and varies between 5 and 20 g /m².
Use of a large thresher in Italy
(C. DalBuono, 7/2009)
Threshing with small machine in Poland
( A. Krakowińska, 8/2009)
Presented methods
• Harvesting between June and July enhances transfer of grasses.
• Harvesting between August and September promotes herbaceous species.
• Donor site register facilitates the selection of suitable sites (example: www.spenderflaechenkataster.de)
Mowing with tractor in Slovakia
(M. Kizekova, 7/2009)
Green hay
• Mowing of species-rich communities and collection of the seed-rich
fresh cuttings with machines or by hand.
• Ratio donor : receptor site depends on biomass production and seed
content of donor site (varies between 3:1 and 1:2).
• Green hay enhances the water supply, reduces erosion and offers safe
sites for germination and establishment.

9 repetitions per method
Amount of harvested material from 1 m² donor site:

- green hay: 583,7 g per m² (SD ± 113,8)
After 3 weeks: 21 March 2010
Greenhouse and laboratory experiments
Greenhouse experiments – results after 4 months
→ for both methods, number
of germinated species is
similar
→ content of germinable seeds
is slightly higher in on-site
threshing material
→ target species comprise
approx. 90 % of germinated
species

First Conclusions

Harvest with thresher /Poland
First conclusions
• Harvesting of species-rich grasslands is an effective way to
obtain regional seed mixtures for restoration and re-vegetation
• Species-richness of donor sites increases restoration success
• On-site threshing and green hay are suitable harvesting
methods and the harvested material is rich in number and seeds
of target species
• Whereas green hay is easier to harvest (tractor with rotary
mower and loader wagon), material from on-site threshing is
bulk reduced and can be stored more easily - after drying - for
later use
