Population justification: The number of Albert's Lyrebirds (1,700-8,300 mature individuals) is calculated as the product of the territory size (9 ha) applied to three independent measures of the area of occupancy (in Stewart et al. 2021), assuming each 2x2 km square within its range (using data from eBird 2020 and BirdLife Australia 2020) represents 1 km2 of suitable habitat. The population is possibly larger as many areas have not been surveyed; consequently, the best estimate (8,100 mature individuals) is placed at the higher end of the population size range. Small isolated subpopulations at Blackwall Range (possibly ten birds; Bower 1997) and Mt Tamborine (23 pairs; Nielsen 2010) continue to persist (BirdLife Australia 2020, eBird 2021) although isolated for well over 50 years.
Trend justification: Earlier sustained declines due to forestry in what is now Whian Whian Conservation Area have ceased and the population is thought to be stable. Some birds died in major fires in 2019–2020 but, based on initial assumptions about mortality at different severity classes (severity low: 10%; medium: 30%; high: 80%; very high: 100%) and maps of fire severity, the total killed was an estimated 6% of the total population with estimates ranging from 4%–8% depending on the fire-related mortality assumptions adopted (G. Ehmke, S.T. Garnett unpublished). In the absence of additional threats, the population is not thought to be undergoing a continuing decline.
