Qualitative & Quantitative Analysis of Adult Arboreal Individuals from the Afforestation in the Municipality of Várzea, Paraíba, Brazil

Abstract

Aims: Perform a qualiquantitative analysis of adult arboreal individuals in urban roads in the municipality of Várzea, Paraíba, Brazil.
 Study Design: Census inventory.
 Place and Duration of Study: Várzea Municipality, Paraíba, Brazil from March to April 2018.
 Methodology: The qualitative and quantitative census inventory of adult shrubs-tree individuals was carried out in the urban roads of the municipality, the level of inclusion of the individuals was circumference at breast height (CBH) of (1.30 m) was ≥ 6 cm. Common name of the species was recorded, CBH measurements, height of the first bifurcation and total and physical conditions that were classified as good, regular, bad and dead. The data were tabulated, processed and presented in tables and graphs.
 Results: A total of 429 individuals were recorded on public roads distributed in 20 species. Azadirachta indica A. Juss and Ficus benjamina L. had the highest number of individuals.
 85% of the species were exotic and 15% were native. 12 species offered direct nutritional benefit to man and local fauna as they were fruit trees. The physical conditions of the individuals were 55.94% good, 40.33% regular, 3.73% poor, however, 47.50% of individuals had some type of conflict. 41.72% of individuals were concentrated in the diametric class of 15-21 cm. 54.78% of individuals had height of the first bifurcation greater than 200 cm and 62% of the individuals medium size.
 Conclusion: The afforestation of the municipality was satisfactory in relation to plant health. Attention needs to be paid to the diversity of native species and the injuries caused to vegetation. The height of the first fork was adequate. The trees were medium sized. It is suggested that studies of perception of afforestation be carried out in the municipality.
