Page scope

Novosibirsk Oblast (growing region) is a Growing Region: a named region that sits above Growing Areas and below the regional complex and gene pool. It covers Novosibirsk Oblast in south-western Siberia: the wild hemp found there and the hemp sown as a crop. The oblast as an administrative unit is the subject of Novosibirsk Oblast.

Why the region is on the map

• The government of Novosibirsk Oblast reported 771.5 hectares of wild hemp found in 2018 and named the six districts with the largest areas: Krasnozersky, Kuibyshevsky, Kargatsky, Kolyvansky, Suzunsky and Toguchinsky (press release of 4 June 2019, from the anti-drug commission of 3 June).
• Earlier oblast figures: more than 40,200 hectares of wild hemp in 2003 (NGS, 4 September 2003) and 577.9 hectares found in the first three months of Operation Mak in 2011 (Academ.Info, 7 September 2011).
• Hemp was grown as a crop in the oblast in 2017 (Omsk Biocluster, 30 October 2017), and hemp growers there use varieties of the Federal Scientific Centre for Bast Crops (Serkov and co-authors, 2024).
• Zykova (2019), of the Central Siberian Botanical Garden, counts hemp among the 34 alien plants that have become invasive in the oblast. Her checklist records it from most of the oblast's districts, with sheets in the garden's herbarium from twelve of them.
• An undated label from the Baraba describes weedy hemp whose stems the local people used for fibre and whose seed they used for oil (MW0062832).

The name

The sources report hemp by the oblast and by its districts, so the region takes the oblast's name. The Baraba is named by one herbarium label only. The words "(growing region)" in the title keep it apart from the page on the oblast itself.

Growing status

The status is Active. The oblast's figures for wild hemp run from 2003 to 2018, and hemp was grown as a crop in 2017. Zykova (2019) records hemp as an invasive weed in most of the oblast's districts. No source says that hemp has stopped growing in the oblast.

How the border is drawn

• The border is a proxy drawn on the whole of Novosibirsk Oblast (OpenStreetMap relation 140294), about 178,000 km², because the government's figures are for the oblast and its districts. Encyclopædia Britannica gives the area as 178,200 km².
• The infobox point (55.28, 79.77) is the centre of the shape.
• The border is not drawn from accession or news points.
• Since October 2026 the map line leaves out ground above 4,000 m (SRTM elevation) and land that ESA WorldCover 2021 maps as bare or sparse vegetation, permanent snow and ice, or open water at its outer edge only, and leaves out lakes of 500 km² or more. Along the oblast's boundary that ground comes to less than half of one per cent of the land, so the line keeps to the boundary; Lake Chany with Malye Chany, about 1,800 km², stays outside it. The Ob and the Novosibirsk reservoir on it are inside the line, which encloses about 176,100 km².

Accessions

Köhler & Nilsson 78 (1971), from dry grassland in the forest-steppe at Lozhok, Iskitimsky District, lies inside the border. Its label does not say the plant was sown, so it is not attached to the region; it is described on the page.

Where the sources disagree

The area of wild hemp reported for the oblast was more than 40,200 hectares in 2003, 577.9 hectares in 2011 and 771.5 hectares in 2018. The sources do not say how each figure was counted, and the page gives each with its year and source and does not compare them.

Open questions

• Whether the Baraba is a growing tract of its own is not settled. One undated label names it; the other sources, Zykova (2019) among them, report hemp by district, and none names the Baraba as a place where hemp grows.
• The 2018 release names six districts with the largest areas but gives no figure for each.
