The leaves on the left side had brown margins, the leaves on the right side were green. 10/07/03 In 2010 the side difference was visible already on 3 July. Southwards (left) visual contact to phone masts Ludwigstr. 2 (275 m) und Ludwigstr. 25 (190 m). Phone mast Heiliggrabstr. 15 (280 m) westwards was hidden behind trees at that time. 12/05/30 13/08/05 12/05/30 970 µW/m² 130 µW/m² Measurement on Measurement on the left side in the right side in a height of 3 m a height of 3 m Measurements on 30 May 2012 standing at the top of a ladder: south side 970 µW/m² (0.60 V/m), north side130 µW/m² (0.22 V/m). On 5 Aug. 2013 the maple had already lost leaves on the left side. 3 Maple, Hauptsmoorstr. 26a (2008-2012) 56 08/06/08 12/05/30 680 µW/m² 80 µW/m² On 8 June 2008 it was noticed, that the northern side of a group of maples (on the right) was damaged. It was the side facing the mobile phone antennas situated on the building. Side beams of the sector antennas reach the maples. View from the west In May 2012 the damage had increased on the left side. The right side showed no damage. 12/05/30 12/05/30 680 µW/m² 80 µW/m² On 30 May 2012 measurements were carried out with the EMF-broadband analyzer HF 59B (27 MHz – 3300 MHz), UBB27_G3, from Gigahertz Solutions (measurement of the sum, peak values of power flux density in µW/m²). Value left side: 680 µW/m², value right side: 80µW/m². This difference can be explained by attenuation within the tree. A part of the RF-EMF is absorbed from the leaves, a part is reflected, scattered and diffracted. 4 Maple, Berliner Ring (2013-2015) 234 13/05/13 View from the east On 13 May 2013 crown transparency was observed in the upper left section.

Leaves on the left side were brown. 15/06/04 2100 µW/m² 290 µW/m² On 4 June 15 the damage had increased. Measurements were carried out on 14 June 2015. 5 Maple at the Cathedral square (2010-2011) 150a Postcard: View from St. Martin to the Cathedral, the New Residence, Altenburg and the maple 150 10/08/10 11/08/02 2300 µW/m² Since 2008 early browning on the eastside.

Birch with crown tranparency in the background. 15/07/30 290 µW/m² 3600 µW/m² On 30 July 2015 dead branches on the south side had been cut. The birch had already lost leaves. The phone mast had been enlarged (12 antennas). Measurements with the help of a telescopic rod. 16/07/01 On 1 July 2016 the dead birch had been felled.

The measurements were done with the help of a telescopic rod. 10 Maple, Hallstadt, cemetery (2008-2016) 642 08/06/27 142 m View from the southeast On 27 June 2008 dead branches were observed on the left side of the maple.
