A survey of avifauna and vegetation communities in Hadejia-Nguru Wetlands, Nigeria

Abstract

An understanding of the ecological relationship between birds and vegetation is important for management and conservation of any wetland ecosystem. Despite the significant importance of the Hadejia-Nguru Ramsar site and an Important Bird Area, little is kn relationship between bird and vegetation communities. Bird diversity and density were examined and compared between Protected Areas (PAs) and Unprotected Areas (UPAs) with attention to vegetation diversity and density. Data were co were surveyed (seven in PAs and seven in UPAs), and point count method was employed. In total, 42, 255 bird individuals, 148 species, 23 orders, and 50 families were identified. Two global species namely, European Turtle Dove (Streptopelia turtur) and Pallid harrier (Circus macrourus) were also recorded. Results showed that neither vegetation diversity nor density correlated with bird diversity nor density in both PAs and UPAs influence the bird diversity and density in both areas. PAs and UPAs of the Hadejia rich in avifaunal species, thus management of these areas will preserve large species diver Increase public awareness in the wetland on the importance of conserving birds and vegetation, as they play a vital role in the ecosystem is strongly recommended. The results presented here provide an overview of the relationship between bird and veg an important input for better understanding of its conservation.

Detection of clade 2.3.4.4 highly pathogenic avian influenza H5 viruses in healthy wild birds in the Hadeji‐Nguru wetland, Nigeria 2022

“…It is one of Nigeria's major wetlands, covering an area of about 3500 km 2 with an altitude of 152–305 m above sea level and a depth of about 1.6–1.7 m. The annual rainfall ranges between 200 and 600 mm, from late May to September. The mean minimum temperature ranges from 12°C in December to January, reaching a maximum of 40°C in April 5,28 . These wetlands are drained by two major rivers, the Hadejia and the Jama'are, which flow and converge into Lake Chad (Figure 1).…”

Impact of Typha Grass on Biodiversity Loss of Hadejia-Nguru Wetland Located between Jigawa and Yobe States of Nigeria: A Review

“…The invasion of Typha grass has led to the vulnerability and endangering of some native vegetation such as Acacia spp. (Ringim et al, 2017). et al, 2006).…”

“…Vegetation such as Acacia spp. are threatened due to the Typha invasion and are important roosting sites for the vulnerable European turtle dove (Ringim et al, 2017).…”

“…Consequently, this may decline the abundance of economically valuable species, in particular those used for food, fodder and/or medicinal plants and loss of local genetic resources thus, genetic diversity (Lynn, 2005). More so, primary production may increase or decrease if plant invader leads to a shift in the major vegetation type of a wetlands area (Ringim et al, 2017). However, most invasive plants increase net primary productivity as in the case with giant reed (Arundo donax), and other Typha spp.…”
