Abstract
Since the foundation of the Swiss National Park (SNP) in 1914, various
long-term projects on botanical research have been conducted there, the
most significant of which comprises a network of more than 160 permanent
vegetation plots. Most of this network was established between 1917 and
1945, and has been maintained by Josias Braun-Blanquet (1917—1938),
Balthasar Stüssi (1939—1992) as well as Bertil Krüsi,
Martin Schütz and Helena Grämiger (since 1993). The permanent
plots are located in alpine swards, sub-alpine pastures, forests, and
several special sites. To complement them, permanent plots for lichens
(maintained 1923—1956) and bryophytes (since 1954), as well as forest
plots (since 1926, 1978 and 1996) have been established. Further long-term
observation projects concern the study of factors affecting vegetation
(with/without grazing ungulates, changes in stream flow) and of special
sites (burnt areas, seeded road verges, avalanche paths).
