Espacialização da Algaroba (Prosopis juliflora) no Distrito Alto dos Coelhos, Água Branca - AL

Abstract

The algaroba P. juliflora is an exotic species and has a higher incidence in countries in the North of South America, arrived in the Northeast of Brazil around 1942 with the first seedling planted in Serra Talhada - PE. The objective of this work was to understand how the algaroba arrived in distrito alto dos Coelhos, Água Branca – AL, evaluating its spatialization in 3 different environments, making a comparison with another area of conserved Caatinga (environment 4) with 1, 91 ha. For the quantitative survey of the algaroba, a delimitation of 3 areas was made with Google Earth, as described: environment 1 (Riacho) with 0.10 ha, environment 2 (Canal do Sertão) 0.82 ha and in environment 3 (Vila Zuleiro) 3, 41 ha. All individuals of the genus P. juliflora were counted in these areas and 86 algarobas were recorded in environment 1 with AD= 890 ind/ha, 392 in environment 2 with AD= 478 ind/ha, and in environment 3, 56 algarobas with AD= 16 ind/ha were added. Thus, a marked dominance of the algaroba was identified in these areas, which in turn was caused by anthropization in overlap of agriculture and pasture, and its significant increase was due to the following facilitating means: water availability, animal feed and deforestation.
