- Hanna Resvoll-Holmsen
Hanna Maria Resvoll-Holmsen (née Resvoll) (
September 11 ,1873 inVågå ,Oppland –March 13 ,1943 inOslo ) was a Norwegianbotanist – a female pioneer in Norwegiannatural history education andnature conservation together with her sister,Thekla Resvoll . She was first married to Hans Dieset (divorced 1901), then from 1909 to state geologist Gunnar Holmsen (1880-1976), brother of her sister’s husband.Hanna Resvoll-Holmsen suffered much from illness in her childhood and school attention after her 12th year was sporadic. She took high school exam 1902, at which time she had also an unhappy marriage behind her. She studied
natural history at the Royal Frederik’s University in Kristiania and graduated inbotany in 1910. From 1921, she was docent inplant geography at the same university, a position she held until her retirement in 1938.Hanna Resvoll-Holmsen participated as a
botanist in theSvalbard expedition in 1907 lead by the oceanographer Prince Albert. The next year she went toSvalbard alone mainly to takephotograph s, partly in colour. These photographs constitute a uniqueearly documentation ofSvalbard ’s nature. Her botanical observations were first published as "Observations botaniques" inMonaco , later in Norwegian as "Svalbards Flora" (1927) – the firstflora of this archipelago.Using
Christen C. Raunkiær ’s quantitative methods [Shimwell, D.W. (1971) The Description and Classification of Vegetation. Sidgwick & Jackson, London.] , she made a large vegetation survey of Norwegianalpine vegetation , published as "Om Fjeldvegetationen i det Østenfjeldske Norge" (On the mountain vegetation in Norway east of the Scandes; 1920). She was particularly interested in thesubalpine birch forests. She published an essay "Om betydningen av det uensartede i våre skoger" (On the significance of heterogeneity in forests), which made plead for the conservation of natural mountain forest and criticized its replacement byspruce plantations. This pamphlet caused much animosity against her among foresters.Together with the geologist Adolf Hoel, she was behind the first designation of a conservation area in
Svalbard . She was a strong advocate for nature conservation in the Norwegian mountains. She is known in Norwegian conservation circles as the country’s first "green stocking".elected scientific works
