The botanical garden at the Institute of Nature and Environmental Technology at Kanazawa University, has a fresh-water reservoir. Several endangered species such as Hydrocharis dubia have been identified in this reservoir. Flora and vegetation surveys were carried out from October 2021 to May 2022. As a result, 53 vascular plants were described, including 7 which were designated as endangered species in Ishikawa Prefecture. More than half of the water surface of the reservoir was covered with floating-leaf plants (H. dubia), and the presence of submerged plants such as Hydrilla verticillata and Ceratophyllum demersum was confirmed under the water surface. Moreover, some invasive alien species such as Solidago altissima were observed in places where soil was deposited. |
