Habitat and Ecology
Pinus maximinoi is a species with a wide ecological amplitude, occurring from wet subtropical forest, where it is a gap pioneer, well up into the cooler cloud forests on high mountains in Mesoamerica. In Mexico it also occupies drier sites as a constituent of pine or oak-pine forest or woodland. Its altitudinal range is great: (450-)600-2,800 m, with an optimum at 900-1,800 m a.s.l. In the NW of its range the species occurs between 1,500-2,800 m. It occurs on a variety of soils under various climatic conditions; in Mesoamerica annual precipitation ranges from ca. 900-2,500 mm, with the wettest conditions on the Atlantic and Pacific slopes of the mountains. Under these conditions it occurs frequently with Pinus tecunumanii and Liquidambar styraciflua, at lower altitudes with P. oocarpa. In secondary broad-leaved forest other pines may join: P. devoniana, P. pseudostrobus, and pine woodland may prevail under a regime of grazing or burning, with the undergrowth dominated by grasses or the fern Pteridium aquilinum. In Central Mexico, it grows at the higher sites with Abies religiosa, P. ayacahuite, P. patula, P. pseudostrobus, P. douglasiana, and often Quercus in mixed pine or oak-pine forest, where precipitation is more moderate but the seasonal temperature range greater, with some frosts occurring in winter.
