to Venman Bushland National Park, and the Eprapah Scout environment training centre. In April 2013, the Redland City Council illegally cleared vegetation from public land on the foreshores of Moreton Bay. The council has been required by the State Government to restore the cleared vegetation and install signage about the restoration. Trees felled included many sheoaks. The city's koala population has declined significantly in recent years. In 2010, it was estimated that only 2,000 koalas remained, a 65% decline since 1999. Figures from a count in 2012 have not yet been released by the Queensland Government. The Redland City-based Koala Action Group has warned that: "Rampant expansion of urban areas will lead to the loss of the koala populations that are vital to the long-term survival of the species." The city boundaries include internationally significant coastal wetlands within the Moreton Bay Ramsar site. Tidal flats, mangroves and seagrass beds provide important habitats for fish, crustaceans, and: large numbers of the nationally threatened green turtle and the loggerhead turtle the internationally vulnerable dugong, a large sea mammal from the order Sirenia which also includes manatee species 43 species of shorebirds, including 30 migratory bird species listed by international migratory bird conservation agreements, such as the vulnerable eastern curlew and the grey-tailed tattler, that use this area in their journey through the East Asian–Australasian Flyway. Freshwater systems in the Redlands catchment do not meet set ecosystem health values, according to the Healthy Waterways Report Cards for both 2013 and 2014. Fire ants have been detected in a number of Redland City suburbs, with Sheldon and Mount Cotton being assessed by BioSecurity Queensland as high-risk, and requiring treatment by ground teams. Transport Queensland Rail operates the Cleveland railway line, which connects the Redlands with Brisbane as part of its City network. The line runs parallel with the Brisbane River to its south, passing through Brisbane's Cannon Hill and Wynnum, before crossing Tingalpa Creek to enter Redland City. Northern suburbs of the city are serviced by five stations: Thorneside, Birkdale, Wellington Point, Ormiston, and Cleveland, where the line terminates. The TransLink (South East Queensland) bus network is prevalent in the Redlands. Bus stations at Capalaba and Victoria Point feature regular city-bound and outbound connections, with direct services to Carindale, Eight Mile Plains, Loganholme, and the Brisbane CBD during peak hour. Upon pending completion, the Eastern Busway is expected to terminate at Capalaba bus station.
