Owen Complex Fauna Monitoring 2018 EXECUTIVE SUMMARY The fauna monitoring program at the Mt Owen Complex was modified in 2017, to account for the requirements for fauna surveys to be conducted in several new biodiversity offset areas. As a consequence, the fauna monitoring schedule for surveys in 2018 was brought forward in 2017, to account for both the new biodiversity offsets and the Mt Owen Complex. Therefore, in 2018, no comprehensive fauna monitoring surveys at the 9 sites were conducted in the Mt Owen Complex. Rather, the works in 2018 comprised: specific threatened fauna species surveys (winter bird census for Swift Parrot, Regent Honeyeater), an initial frog survey in February 2018 for the endangered Green & Golden Bell Frog, and habitat improvement works. Climatic conditions experienced in 2018 remained very dry with below average rainfall recorded (405mm compared to the 2002-2018 average of 649mm). Several rainfall events were recorded in 2018, but comprised occurred on a limited number of days per month, resulting in extended periods of dry weather. No rainfall events were significant to restore or fill any water bodies at the Mt Owen Complex, resulting in most water bodies being dry since mid 2017. An initial frog survey was conducted in early February 2018. Many water bodies that comprise monitoring sites for frogs were dry, and remained so during 2018. No further monitoring surveys were conducted in 2018 due to absence of water and no presence of active frogs. In 2018, despite most of the works targeting habitat restoration, one new species was detected, the Banded Lapwing. This species is typically associated with drier inland habitats, but many observations of this species were recorded in the Hunter Valley in 2018. Their presence in the Hunter Valley is attributed to the dry conditions inland. The cumulative total for bird species at the Mt Owen Complex is 171 species. No presence of the nationally threatened Swift Parrot and Regent
