Management implementation within the model. The user-specified prevalence at which management began was varied systematically to take on values 0.001, 0.010, 0.100 and 1.00. S_Reserv and S_Recip reference the proportion of susceptible reservoir and recipient hosts, respectively; and I_Reserv and I_Recip refer to the proportion of infected reservoir hosts and recipient hosts, respectively. β is the transmission coefficient. N is the number of reservoir hosts per occupied cell and e_ij denotes the movement rate between the ith and jth cells. Throughout our simulations, we took a cell's neighbourhood to consist of all cells whose centroids were within three cell lengths of the target cell.

action	prevalence at which action begins	effect of action on system dynamics	action's spatial extent
biosecurity	user-specified	βIReservSRecip becomes δβIReservSRecip where δ∈(0, 1) is a multiplicative factor reducing β	neighbourhood of target cell
containment	user-specified	eij = 1/10 000 when i and j are not on the same side of the containment boundary	all cells
depopulation	user-specified	I reset to 0 when depopulation occurs	neighbourhood of target cell
prophylactic vaccination	n.a.	S reset to S(1 − ν), where ν ∝ N/cell, the host's density within a cell	all cells
retroactive vaccination	user-specified	S reset to S(1 − ν), where ν = 1/R0, the herd immunity rate	neighbourhood of target cell
selective removal	user-specified	IReserv is reset to 0, and SReserv is proportionally increased	neighbourhood of target cell
