In building a house on his own property, defendant severed roots of a large pine tree that was partly on defendant’s property and partly on plaintiff’s. Following Scholes v. Lambirth Trucking Co. (2020) 8 Cal.5th 1094, this decision holds that plaintiff can recover only single damages for killing the pine tree. The injury to the tree occurred from severing roots on defendant’s own property and not from any trespass onto plaintiff’s property. And even if a technical trespass to the tree itself, it was not the sort of timber trespass addressed by Civil Code 3346 and CCP 733, which provide for double or treble damages. The trial court also erred in calculating the single damages. The expert evidence on valuing the tree used the “trunk formula method” which calculates a non-depreciated value for the tree and then reduces that value by type of tree, condition and location. The trial court wrongly used the non-depreciated value ($73,000) which failed to take into account the actual characteristics of the particular tree that was killed. The $37,000 depreciated value should have been used instead.
