BPT diagram for long and short GRB hosts and GRB sites from the literature compared to SDSS galaxies (grey dots) and the two SF regions in the host of GRB 100418A (stars). The redshift of the hosts is colour-coded in the plotted symbols. Emission line fluxes used are taken from Christensen et al. (2008), Berger (2009), Han et al. (2010), Levesque et al. (2010), Perley et al. (2012), Schulze et al. (2014), Thöne et al. (2014), Krühler et al. (2015), Stanway et al. (2015), Vergani et al. (2017), Izzo et al. (2017).
