The urban population has grown sharply driven by the rural exodus and the expansion of capitalist relations in the countryside. The term "green area" with respect to accessible urban spaces that relate to health, recreation and provide interaction between human activities and the environment. The concept of "park" is related to a green area for recreation and leisure of the population. In this context stands out from the Parque da Escola Superior de Agricultura "Luiz de Queiroz", commonly known as ESALQ Park, located on the campus of the University of São Paulo, Piracicaba, SP. Formed by a range of native and exotic plant species used in courses at ESALQ for purposes of research and teaching activities, directly contributes to easing the regional microclimate, with its 50.000m² representing 5.15% of the green areas of the city. Designed by landscape architect Arsenio Puttemans, was deployed in 1907 which were planted the first distributed in syndicated massive trees. Floristic studies was enhanced by the establishment of native shrub and tree species not originally used in landscape design, which entered the park through the dispersion of a remnant forest training plateau or semideciduous seasonal forest. Studies of Systematic Botany provide numerous benefits to the description of the vegetative and reproductive characters, for identification of tree species. Techniques already in Wood Anatomy seek in the wood anatomical characters, devices that allow us to correctly identify the tree species, providing the basis for indicating those with potential for timber use. Previous floristic studies showed the presence of about 250 tree species in the Park ESALQ, with different botanical families presence of economic interest. Thus, based on these previous studies, this study aims to select 120 most representative tree species at the site, being listed species with timber potential of landscape interest, medical interest, the introduced exotic, endangered, among other categories in order to provide knowledge on the species richness of the Park. Will be collected terminal branches containing plant material (leaves and seeds) and, when available, material reproductive (flowers and fruits), and samples of non-destructive wood of branches being processed according to specific standard literature. After identifying the species, herbarium specimens with plant material and prepared specimens with samples of wood for microscopic analysis will be mounted. After the description, two keys will be developed to enable the identification of trees in the field, based on dendrological and anatomical characters of wood. Following will evaluate the phytosanitary conditions of tree specimens, following parameters: (i) evaluation of the specimens as healthy or disease and / or pest; (ii) the intensity of the attack, mild when no damage to the force and function of the tree; average, when there is little commitment to the force; and heavy, when high commitment to the vigor of the plant occurred; and (iii) relating to the types of pruning, through visible signs of pruning the tree individual, classifying them according to the available literature. Anyway, records with botanical illustrations and images obtained from plant material and records with macro and microscopic images of the wood, to assist in the visualization and identification of tree species in the field will be developed. It is expected that the results obtained serve as reference literature in future plans for sustainable management of the site, in order to support and disseminate the knowledge and the preservation of this important biological, landscape, historical and cultural patrimony of Brazil.
