Finding suitable tree species that not only grow well on nutrient poor soils but are also safe financial investments is one of the major obstacles to successful reforestation efforts in the tropics. Our study compared the financial viability and growth of valuable timber species in monocultures and mixtures on infertile soils. Our work shows the extraordinary growth in volume and value of  Dalbergia retusa  and  Terminalia amazonia  while underscoring the poor financial viability of  Tectona grandis  and  Pachira quinata , all commonly planted timber species in Panama and much of Central and South America. Using Bayesian statistics, our predictions show that  T. amazonia  monocultures could reach nearly 200 m 3  ha −1  of merchantable volume after 30 years compared to the ~ 40 m 3  ha −1  that  T. grandis  could accumulate in the same time frame. While  D. retusa  monocultures did not have the highest predicted merchantable volumes of all the species, it did have the highest predicted net present value (NPV), with a predicted mean NPV of &gt; US$97,000 ha −1 , quadrupling the species with the next highest monoculture’s NPV,  T. amazonia  monocultures (~ US$20,000 ha −1 ). Our work emphasizes that reforestation can be financially viable on low nutrient soils, even in the absence of fertilization or other silvicultural manipulations, if species selection and site are carefully considered and matched.
