The PPGF also has experimental areas within the university campus of Irati, comprising Pinus spp. and Eucalyptus spp. plantations, which have been used to support practical classes and research development.
The infrastructure of the National Forest (Flona de Irati) is noteworthy, which is an important conservation unit managed by ICMBio – Chico Mendes Institute for Biodiversity and Conservation. The Program has an important partnership with Flona de Irati for the use of that space for practical classes, technical visits, and mainly for conducting research. The national forest is located 15 km from the University Campus, with a total area of 3,495 hectares, of which 1,308.71 hectares are planted forests and 1,272.90 hectares are Araucaria Native Forest (Mixed Rain Forest). It is an incomparable space for research, as in addition to having Pinus and Araucaria plantations, it also has an important fragment of Mixed Rain Forest (FOM). The Program has an important experiment in this fragment where it has been monitoring the dynamics of the FOM since 2002 with 25 permanent plots of one hectare each, totaling 25 hectares, completing in this year of 2020, 18 years of monitoring of almost 15 thousand trees existing in the sample area. Another set of 10 permanent plots were installed in another nearby area in 2005 with a similar methodology, but in this case this area has been monitored for 15 years in order to assess the natural regeneration under a Araucaria angustifolia plantation from the 1940s, also evaluated every three years, where spontaneous regeneration occurs which looks like a native forest. These permanent plots have been responsible for several completed and ongoing studies, mainly in the area of forest management, but also involving other areas with the participation of Professors and Potsgraduate students, which has enabled several dissertations and theses to be developed with national and international publications. It should be noted that the Program also has 26 permanent plots in the Três Barras National Forest, Santa Catarina state, which follows the same methodology as the Flona de Irati, and in this case involves more than 18 thousand trees which have been monitored since 2004.
