The greening of slip areas and erosion areas through the use of site-adapted species was also part of Weinzierl's work, pointing the way to problems that are more relevant than ever a hundred years later. The First World War ended these successful approaches.

After the Second World War, the usual seed production of landraces came to a standstill. After successfully breeding varieties for field fodder production, an extensive program for breeding grasses and legumes for use in seed mixtures for permanent grassland began in Gumpenstein 15 years ago. Furthermore, a program was started to produce seeds of alpine and subalpine ecotypes for erosion control and landscaping.

As a result of these efforts, a cocksfoot variety has already been brought onto the market that sets new standards, especially in terms of quality. Other varieties of golden oats, English ryegrass and bastard ryegrass, comb grass, red bentgrass and horn clover are already largely used in quality seed mixtures. Furthermore, in recent years a spectrum of 18 subalpine and alpine grasses, legumes and herbs have been selected that are used for revegetation in high altitudes.

An important part of the work was supporting and advising the seed producers. In three centers, mainly Gumpensteiner varieties are propagated on an area of ​​more than 600 hectares, with a sharp increase in the number of propagation areas. The production of site-appropriate ecotypes is already being carried out on more than 80 hectares, and the seeds are used in special seed mixtures. HBLFA Raumberg-Gumpenstein varieties are used exclusively in ÖAG quality mixtures. These ÖAG mixtures are a quality standard under private law, developed in collaboration by the HBLFA Raumberg-Gumpenstein with research, trade and practice. Already 40% of the total tonnage for grassland is sold by 4 different seed companies in this quality.
