Parks are considered one of the main areas that provide ecosystem benefits for urban centers, characterized by the diversity of species found, performing a landscape and/or social function and contributing to the environmental quality of cities. Therefore, the study aims to inventory the afforestation of the Maria Anita Amazonas Macdowell Municipal Park qualitatively and quantitatively, providing support for the management of green areas in the municipality of Camaragibe – PE. To this end, an arboreal-shrub inventory was carried out, carried out quantitatively, evaluating quantitative parameters, including: number of individuals, species, total height and circumference at breast height. The qualitative diagnosis was carried out by evaluating the following parameters: phytosanitary conditions, mechanical injuries, conditions of the root system and general condition of the individual. In addition, the soil cover classification was carried out and the vegetation cover indices for the municipal park were calculated. 92 individuals were found among trees and palm trees, distributed in 11 botanical families and 13 species. It was observed that 37% of the individuals are less than 3 m tall and 59.78% dbh between 3.7 and 18.6 cm, indicating that they are young individuals from a recent planting. The quality of the park's afforestation is considered good, as 95.65% of individuals are in good physical condition without presenting problems that compromise their development. The presence of anthills was observed in 31.52% of the individuals, only 4.35% had superficial roots. Regarding mechanical injuries, 33.70% of individuals had some type of pruning. The park has an area of 18,602.28 m2, of which 10.68% is tree coverage, 61.29% permeable coverage and 28.03% pavement coverage. In relation to the total green area index (0.126 m2 hab.-1), vegetation cover index (0.013 m2 hab.-1) and percentage of vegetation cover (10.68%), the values found for the park were much lower considered satisfactory. Therefore, it is recommended to implement public policies to raise environmental awareness and plant new individuals, so that the best environmental conditions can be offered to the population in the future.
Estudo comparativo entre os sistemas de drenagem convencional e sustentável para um loteamento no município de Gravatá - PE

As a result of disorderly population growth, increased deforestation and pollution in recent years, cities are experiencing the great challenge of dealing with rain runoff problems. Due to the soil waterproofing, problems such as flooding and inundation resulting from natural events are increasingly frequent, and in addition to it, the lack of planning in cities. To solve this problem, it is necessary to use urban drainage elements that act efficiently in the capture and adequate conduction of rainwater, reducing the negative impacts on the population and the environment. In this context, the present study made a comparative analisys between conventional and sustainable drainage systems for a subdivision in Gravatá-PE. The conventional drainage system was dimensioned with the use of gutters, storm drains, manholes, detention reservoir and culverts. The sustainable drainage system, on the other hand, was designed with partial replacement of waterproofed coatings with green areas, use of interlocked pavements, hollow blocks, infiltration trenches and a detention reservoir with a permeable bed. The results showed that the increase in green area, in addition to providing environmental comfort, also contributed to the reduction of surface runoff, reducing the risk of floods and waterlogging. Besides, by providing greater infiltration of water into the soil, sustainable drainage showed savings in the use of devices. Therefore, the study showed that the adoption of sustainable measures, from the conception to the execution of the projects, can be the solution to the current problems faced regarding urban drainage.
