Avian community assemblage and vegetation association in emergent marsh at Arkansas Post

Background: Throughout the United States we have seen a trend of wetland habitat loss. This
trend has been particularly pronounced in Arkansas where much of the wetland habitat complex
has been impacted by agricultural and timber practices. With this loss we have also seen
associated decline in the wildlife populations that rely on these types of habitats. The King Rail
is a wetland species that rely on a complex of emergent vegetation broken by open water that has
seen significant decline due to the loss of this habitat type. Due to these losses and the decline of
the species it is especially important to not only be able to track population trends, but it is
imperative to target sites which have high potential for occurrence of these species for protection
and management. Historically this is a species that is not well captured under normal bird survey
protocol which leaves a gap in current understanding of population levels. We propose that by
utilizing Audio Recording Units in conjunction with marsh bird monitoring protocols that this
gap can be minimized to give a better understanding of true population trends.
