URBAN ARBORIZATION IN BLOCKS OF DIFFERENT BUILDING PATTERNS IN JATAI CITY

The study aimed to comparatively evaluate the quality and quantity of tree planting in the urban perimeter of Jatai city, Brazilian central region. To make comparisons possible, a georeferenced map of all blocks in the city was used. These were partitioned into three categories by the building parameters, denominated 1. high/medium, 2. simple and 3. precarious patterns. For each category the urban arborization of 60 blocks, randomly selected on the map, independent of the quarter was evaluated. The survey detected 114 different species and 1953 trees, distributed into 1853 exotic and 100 native species. Oiti (Licania tomentosa) was the more common species used in arborization, with 31% of all trees surveyed. The tree average number was significantly higher in high/medium and simple patterns than the precarious pattern. When considering the sidewalk position, the high/medium pattern showed the greatest adjustments in planting. Medium and small tree weight species and palm trees were more abundant in high/medium patterns. This study showed evident differences in urban arborization between categories compared to the streets of the Jatai city. Thus, the results can allow and technically instruct the prefecture, as well as the entire population of this city about forms of better planting, choices of appropriate seedlings and maintenance until maturity.
