Table 2 Allometric functions used to estimate tree AGB

Species	Function	R²	bd range (cm)	Source
Prosopis affinis	ln(AGB) = − 3.23 + 2.61*ln(bd)	0.97	5 < bd < 35	Sione et al. (2019)
Prosopis nigra	Lln(AGB) = − 2.86 + 2.60*ln(bd)	0.98	5 < bd < 40	Sione et al. (2020a)
Vachellia caven	ln(AGB) = − 3.70 + 2.83*ln(bd)	0.97	5 < bd < 25	Sione et al. (2020b)
Celtis ehrenbergiana	ln(AGB) = − 12.5 + 1.28*ln(CA)	0.68		Conti et al. (2013)
A. quebracho-blanco	AGB = 0.074 * bd^2.59 * e^−0.15	0.97	10 < bd < 60	Gaillard de Benítez et al. (2002)

AGB = aboveground biomass (kg), bd = basal diameter (0.3 m aboveground, cm), CA = crown area (cm²)
