The primary aim of this study was toinvestigate the annual water consumption of an individual Anatolian black pine[Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe] growing in Belgrad Forest,İstanbul. The sample tree was 56 years old, measuring a height of 17 m and adiameter at breast height of 40 cm. The study was conducted over a period of 1year from January 1, 2016, to January 1, 2017. The minimum and maximum airtemperatures were −11°C and 32°C, respectively. The precipitation during thisperiod was recorded as 1,083 mm. Tree water consumption measurements werecarried out using the tissue heat balance method. Results showed that wateruptake of the tree varied between 0.007 and 71.54 kg day−1, while the averagedaily and annual water consumptions of the tree were about 27.06 and 9,851 kg,respectively. The daily water consumption varied between 59 kg in July and 3.37kg in January. These values can be considered as guidance for an effectivemanagement of forested watersheds in terms of both water quality and waterproduction.
