菜の花とよく似た花をさかせるハルザキヤマガラシは要注意外来生物に指定されています。
4月28日、樽川堤防（木島平村）と千曲川堤防（飯山市）においてハルザキヤマガラシの駆除活動が行われました。これは本校生徒会がよびかけたもので、本校生徒、飯山高校生徒、一般の方を合わせて５０名を超える賛同者が集いました。
参加者は、晴天のもと額に汗しながらハルザキヤマガラシを一本ずつ抜き取り、袋に入れ駆除しました。今回の取り組みは“一人の百歩より百人の一歩”というSDGsの考え方にそったもので、地道ではあるけれどゴール（＝地域の生態系を守る）にむかう一歩といえるでしょう。
Haruzaki Yamagarashi, which produces flowers similar to rapeseed, is designated as an invasive alien species that requires special attention.
On April 28th, a weeding activity was conducted along the banks of the Tarugawa River in Kijimadaira Village and the Chikuma River in Iiyama City. Supported by our school's student council, this activity gathered more than 50 participants, including students from Norin High School, Iiyama High School, and local community members.
With the sun shining and sweat on their foreheads, the participants pulled up Haruzaki yamagarashi flowers one by one, placed them in garbage bags, and cleaned up the area. This steady, hands-on effort is in line with the SDGs concept that “a hundred steps by one person is more valuable than a hundred steps by one person.” It is a meaningful step toward protecting our local ecosystem.
