Efeito do pastejo na composição e na diversidade florística durante o pousio em El-Tarf, Argélia

Palavras-chave: asteraceae, fitomassa herbácea, intensidade de pastejo, riqueza florística, nitrogênio total

Resumo

Na região de El-Tarf, localizada no nordeste da Argélia, as terras em pousio são frequentemente utilizadas como pastagens para rebanhos de ovelhas, onde ficam o dia todo com uma carga significativa de pastoreio. Estudos limitados conduzidos para avaliar os efeitos do pastoreio têm produzido resultados variados e às vezes contraditórios, destacando assim a necessidade de dados locais confiáveis. O estudo tem como objetivo avaliar o impacto do pastoreio na riqueza florística, diversidade, produção e composição química das terras em pousio na região de El-Tarf (nordeste da Argélia). As medições foram realizadas durante o período de vegetação ótimo de março a junho ao longo de um período de 2 anos (2019 e 2020). O desenho experimental incluiu um único fator: intensidade de pastoreio (sem pastoreio, pastoreio moderado e pastoreio intenso). Os resultados indicaram que o pastoreio reduziu a riqueza florística e a diversidade (Diversidade Máxima, Índice de Shannon e Weaver, Índice de Equidade), mas não teve efeito na cobertura. A terra em pousio não pastada é mais rica, hospedando 23 espécies herbáceas distribuídas entre 8 famílias botânicas, sendo as mais representadas as Asteraceae (39 %), seguidas pelas Poaceae (26 %). As Fabaceae, por outro lado, exibem uma representação mais modesta, representando apenas 13 %. O pastoreio também diminuiu significativamente a biomassa e a fitomassa herbácea total acima do solo, com melhorias observadas em condições não pastadas, registrando valores de 3,80 t.MS.ha-1 e 1,77 t.MS.ha-1, respectivamente. Além disso, o pastoreio teve um impacto significativo na composição química, com os valores mais altos registrados para pastoreio moderado, alcançando 14, 7 % para o conteúdo total de nitrogênio e 11, 66 % para o conteúdo mineral.
