当学会は、これまで、中流（２００６年度・福生）、下流（２００８年度・川崎）、上流（２０１０年度・奥多摩）と、各流域での開催を積み重ねてきた。第４回目となる今回は、テーマを中心とした開催趣旨に切り替え、「生きものおよび生きもの環境から、望ましい河川環境を考える」というテーマのもと、中流域の日野市で、２０１３年１月１３日（日）に、都立日野高校を会場に、開催した。参加者は、発表者や実行委員も含め、これまでの学会でも最も多い、１２０名に及んだ。

午前中の２名の記念講演、午後の９名による一般発表が中心であり、内容的にも、昆虫、植物、野鳥、魚、地質と幅広い分野の研究成果や話題提供が行われた。（添付のレジメ集参照）

また、他には、プレイベントも開催され、最寄りの駅から学会会場までの、地元野鳥保護団体による早朝探鳥会も開催された。また、休憩時間には、浅川の竹で作ったリコーダー演奏・製作教室が行われたり、研究発表のパネルや標本等の展示、生きもの写真展なども、終日行われた。

This Society has held meetings at the midstream basin (Fussa in FY 2006), downstream basin (Kawasaki in FY 2008), and upstream basin (Okutama in FY 2010). This fourth meeting was held at the Hino Tokyo Metropolitan High School in Hino City of the midstream basin on January 13, 2013 (Sunday), with the theme “Studying a desirable river environment from the viewpoint of living creatures and their living environment.” There were up to 120 participants, including presenters and the executive committee members, which was the largest number of participants for the Society.

The focus of the conference was commemorative lectures given by two presenters in the morning and the general presentations by nine presenters in the afternoon. Their presentations covered research results from a wide variety of fields including insects, plants, wild birds, fish, and geology, and provided various ideas for discussion. (See the attached summary of presentations.)

In addition, pre-events were held, such as the local wild bird conservation groups holding an early morning bird watching event in the area between the nearest train station and the conference venue. There were also workshops on making and playing recorders made from bamboo from the Asakawa River during the breaks, and exhibits of specimens and panels of presentations and photos of living creatures throughout the day.
