Abstract: Tree shade is the main element of the thermal comfort for grazing animals. The definition of the quality shadows is an important factor for rural producer decision making. The current experiment evaluated the thermal quality of some arboreal species using climatic data and animal thermal comfort indexes. The species studied were: Pera glabrata Baill (Sapateiro), Copaifera langsdorffii Desf (Copaiba), Platycyamus regnellii Benth. (Pau Pereira), Anadenanthera mocrocarpa Brenan (Angico), and Enterolobium contortissiliquum Morong (Orelha de Porco). They were recorded and analyzed at 12:00 PM, 2:00 PM, and 4:00 PM. The registered climate data were dry-bulb temperature, wet-bulb temperature, wind speed, relative humidity, black globe temperature, light intensity, and thermal comfort indexes, such as BGHI and RTL, during the seasons of year. The randomized blocks design was used for statistical analysis with Tukey's multiple comparison tests (1%). The arboreal species that provided the best thermal quality of shadow, with a higher reduction on the thermal heat load were the following: Anadenanthera mocrocarpa Brenan, Platycyamus regnellii Benth, Copaifera langsdorffii Desf, Enterolobium contortissiliquum Morong and Pera glabrata Baill. The phenotypic characteristics to each studied species had a fundamental influence on the shadow quality.
