Seih Sou

Seih Sou or Seikh Su (Σέιχ Σου, from Turkish: Şeyh Su, meaning the Sheikh's Water), also known as Kedrinos Lofos (Greek: Κέδρινος Λόφος, Cedar Hill), is a hilltop forest just to the north and northeast of the city of Thessaloniki, Greece, that rises to the west of Mount Chortiatis.

Around 80 types of birds frequent the forest, chief among them the short-toed snake eagle, the common cuckoo, nightingales, the rock partridge, owls, and the song thrush.

The southwestern portion of the forest was originally called Chilia Dentra (Greek: Χίλια Δέντρα), or Thousand Trees, as it was one of the parts that was spared deforestation during the Ottoman period.

[citation needed] It was during the Ottoman period that the area received the name شهیح‬ سو, or Şeyh Su in the modern Turkish alphabet, meaning the Sheikh's Water.

The name Kedrinos Lofos (Greek: Κεδρηνός Λόφος), or Cedar Hill, was also given in 1987 when a local author, Georgios Vafopoulos, suggested it in Thessaloniki's city council.

Originally, the area was an oak (primarily Quercus pubescens) forest that was the source of all the rivers that ran through the city of Thessaloniki and ultimately emptied into the Thermaic Gulf.
