posted on 2025-03-16, 00:35 authored by Nobuhiro Akashi

The flowering levels of the dwarf bamboo Sasa sect. Sasa were surveyed along major roads by Integrated Grid Square of Japan (so-called 2nd mesh, 5 min. along latitude, 7 min. 30 sec. along longitude, ca. 10 km square) to determine the area of mass flowering in Hokkaido, northern Japan in 2022 and 2023.

Categories

0: No flowering were found

1: Small flowering areas were slightly found

2: Flowering patches were occasionally found

3: Approximately half of Sasa sect. Sasa were in flowering

4: Most of Sasa sect. Sasa were in flowering

9: Sasa sect. Sasa were not found

Null: Not surveyed

Files

CSV file (Sasa2022-2023.csv) includes Mesh ID and data for 2022 and 2023.

GeoPackage file (Sasa2022-2023.gpkg) was created with 2nd mesh grid (Biodiversity Center of Japan, Ministry of the Environment). Coordinate Reference System is WGS84 (EPSG: 4326).
