Modelling approach. Woody plant encroachment is a natural process that can be observed on a global scale. However, it is difficult to account for the complex and nonlinear ways in which it can alter the physical and biogeochemical properties of ecosystems, and in the absence of long-term monitoring there is no standardised approach that models can use to quantify the process. To date, the majority of the models have tended to be based on a reduced set of models (Takagi et al. 2008 54 ; Moss 2014; Moss 2014; Steen and Montanes 2016; Svinth and Walker 2017). These include a detailed analysis of the Moss (2014) 54 model and the Steen and Montanes (2016) 55 tree cover model. However, they have tended to focus on vegetation dynamics but not the impact that this has on the sub-surface. A commonly used simplified model in conjunction with remotely sensed data is Ritchie et al. (2010) 56 . Ritchie et al. (2010) 57 modelled woody encroachment in central Australia for a 40-year period (from 1980 to 2100) using a coarse scale GIS model. Ritchie et al. (2010) 58 considered two land use scenarios where the landscape transitioned over the period as woodland cover increased: (i) 30-50% and (ii) 50-80%. For both scenarios they found that both NPP and mean annual temperature increased. As a result of the increase in temperature, NPP in (i) increased by 20% by 2100 and by 50% in (ii).
