Answer seems to either poison, kill and disable and best to prevent reproduction of the acacias predators.
Seems to clearly have adverse effects on both sexes of ruminants and thier ability to reproduce. Maybe not specificly DMT but related compounds the plant may not be seeking a dirct effect but that of loading the animals system with the metabolites of DMT.
Fortunately at least some acacia species don't seem harmful in moderation eating a stomach full daily another thing though, even Mimosa Hostilis is clearly Teratogenic causing multiheaded cattle.
Well heck your offspring might be able to smoke 2 pipes.
Seems that DMT is produced primarilly underground in the protective bark of the roots.
It would seem it would seem to have antifungal, antibacterial, and insect worm nematode related protections maybe its being produced wholesale underground and is displaced into the upper bark and stems as a defence mechanism.

Effect of dietary phenolic amines on testicular function and luteinizing hormone secretion in male angora goats
Many agriculturally important shrubs of the genus Acacia can contain high concentrations of sympathomimetic phenolic amines. These compounds, which are thought to represent plant chemical defenses against herbivory, can affect different physiological processes of higher animals if they enter into the systemic circulation (Smith, 1977; Evans et al., 1979; Forbes et al., 1995). The sympathomimetic phenolic amines present in A. berlandieri have been implicated in the development of a toxic condition in sheep and goats when this shrub is consumed for extended periods (Camp et al., 1964). Parenteral administration of phenolic amines present in A. berlandieri and A. rigidula impairs reproductive function of female goats (Forbes et al., 1993) and heifers (Carpenter et al., 1994) and suppresses LH release after GnRH administration in wethers (Forbes et al., 1994). Further research is required to determine the occurrence of subtoxic effects in domestic ruminants that regularly consume vegetation with high concentrations of phenolic amines. In the present study, male Angora goats were allowed to graze on a range site dominated by A. berlandieri and A. rigidula to test the hypothesis that consumption of these plants does not affect testicular characteristics or function or systemic LH concentrations.
The results of this study indicate that consumption of phenolic amine-containing vegetation may affect the function of the pituitary-gonadal axis in domestic
goats, as has been suggested in recent studies involving parenteral administration of some of the phenolic amines present in A. berlandieri and A. rigidula (Forbes et al., 1993, 1994; Carpenter et al.,1994).
In terms of testicular characteristics and function, the increase in testosterone secretion by the testes, which normally occurs in male goats as the breeding
season advances (Muduuli et al., 1979; Ritar, 1991; Pe?rez and Mateos, 1995), was clearly suppressed in the PA bucks.
Acute parenteral administration of some of the phenolic amines present in A. berlandieri and A. rigidula inhibited GnRH-stimulated LH secretion in wethers (Forbes et al., 1994).
Increased LH concentrations and augmented LH response to GnRH observed on d 75 in the PA bucks was probably a consequence of reduced negative feedback of testosterone because testosterone was lower in the animals consuming A. berlandieri and A. rigidula. Over the long term, PA males seemed to have a diminished testicular responsiveness to LH. This was reflected during the pre-GnRH period by decreased plasma testosterone despite increased LH and a lack of correlation between plasma concentrations of LH and testosterone. This reduced testicular responsiveness to LH was also evident during the GnRH-stimulated period, as reflected by a decreased testosterone response to GnRH-induced LH release. A possible direct or indirect effect of phenolic amines on testicular function, the latter mediated through their ability to stimulate cortisol secretion (Forbes et al.,1994), may have influenced testicular responsiveness to LH because cortisol has been demonstrated to affect LH-stimulated testicular steroidogenesis (references in Vera-Avila et al., 1996).
Results of the discriminatory analysis indicated that serum testosterone, change in SC, and serum T3 and T4 were the response variables most correlated with treatment when considered independently (independent R2) , and with the exception of T4, when considered in a complete model including all of the other variables (partial R2) . Serum testosterone, serum T3, and change in SC provided most of the discriminatory power (ASCC = .60) that could be achieved by including all variables in the model (ASCC = .64). Thus, according to this analysis, diminished serum testosterone and SC and increased serum T3 concentrations most accurately characterized the differences between PA and CO bucks.
