[2] The nearby Tel Poleg archaeological site was excavated, revealing a fortified city of the Middle Bronze Age.

The original opening in the kurkar ridge was made in the Bronze Age, and reopened during the Roman period.

The opening was cleared again in 1935, and the stream's current course was set in the area east of the kurkar ridge.

[6] The marsh, known by the Arabs as Birkat Ramadan, remained south of Tel Yitzhak as late as 1945, and was a popular hunting location with abundant wildfowl.

[9] Flora in the reserve includes a coastal variety of Boxthorn, Ephedra aphylla, Calicotome villosa, the endemic Rumex rothschildianus, Iris atropurpurea, Lupin, and Tulipa agenensis sharonensis.
