MUNOZ FLORES, H. Jesús et al. Areas with potential for commercial timber plantations of Pinus pseudostrobus Lindl. and Pinus greggii Engelm. in Michoacán. Rev. mex. de cienc. forestales [online]. 2011, vol.2, n.5, pp.29-44. ISSN 2007-1132.

The establishment of forest plantations is an alternative for recovering degraded land, reducing erosion rates and securing supplies for the forest industry. Various species of conifers and broadleaves have been used in plantations in Michoacán State, México. Experience shows low survival and poor growth due to various factors such as lack of purpose, unsuitable species, inappropriate stocking and insufficient of silvicultural treatments. The aim of this study was to determine the potential areas for commercial forest plantations of Pinus pseudostrobus and P. greggii in the State of Michoacán. Areas were identified using IDRISI 32, and ArcView software. Screening variables include: land use, soil type, mean annual temperature, annual precipitation, elevation, and slope. Products obtained were field verified. Potential areas for commercial forest plantation establishment are: for P. pseudostrobus 234.766 ha (0-15% slope), and 99.760 ha (15-30% slope); for P. greggii 253.626 ha (0-15% slope), and 108.365 ha (15-30% slope). Potential areas identified through GIS stand a better chance to reach survival and good growth goals.
