**2.3 EH1 planting density study**

Study 3, an intensively managed 8+ ha demonstration planted in May 2011 on sandy former citrus beds at two planting densities (**Table 1**) was monitored through December 2017. Stand-level whole-stem green weight equations [19] used periodic data through 81 months to model growth scenarios at the original two planting densities and an intermediate density of 1,794 trees/ha assuming original and two coppice rotations for each density, with the two coppices growing at 90% and 80% of the original planting. EH1 stem wood carbon content was assumed to be 25% of stem green weight, and 78% of total carbon sequestration was in stem wood.
