The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region is considered to be part of the western outskirts of the Greater Sydney area. The region borders on Sydney's main metropolitan area, its foothills starting about 50 kilometres (31 mi) west of centre of the state capital, close to Penrith. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. As defined in 1970, the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin.
The Wollemi National Park is a protected national park and wilderness area that is located in the Central West and Hunter region of New South Wales, in eastern Australia. The 501,703-hectare (1,239,740-acre) park, the second largest national park in New South Wales, contains the 361,113-hectare (892,330-acre) Wollemi Wilderness – the largest such wilderness area in Australia – and is situated approximately 130 kilometres (81 mi) northwest of Sydney.
Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations. 25% of Australia is managed for conservation.
The Springbrook National Park is a protected national park that is located in the Gold Coast hinterland of Queensland, Australia. The 6,197-hectare (15,310-acre) park is situated on the McPherson Range, near Springbrook, approximately 100 kilometres (62 mi) south of Brisbane. The park is part of the Shield Volcano Group of the UNESCO World Heritage–listed Gondwana Rainforests of Australia.
A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, specicide, widespread violence or intentional culling. Such events can reduce the variation in the gene pool of a population; thereafter, a smaller population, with a smaller genetic diversity, remains to pass on genes to future generations of offspring. Genetic diversity remains lower, increasing only when gene flow from another population occurs or very slowly increasing with time as random mutations occur. This results in a reduction in the robustness of the population and in its ability to adapt to and survive selecting environmental changes, such as climate change or a shift in available resources. Alternatively, if survivors of the bottleneck are the individuals with the greatest genetic fitness, the frequency of the fitter genes within the gene pool is increased, while the pool itself is reduced.
Wollemia is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents only one of three living genera in the family, alongside Araucaria and Agathis. The genus only has a single known species, Wollemia nobilis, which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges 150 km (93 mi) north-west of Sydney. The genus is named after the National Park.
The year 1994 in science and technology involved many significant events, listed below.
The Colo River, a perennial stream that is part of the Hawkesbury-Nepean catchment, is located in the Central Tablelands of New South Wales, Australia.
The Wollemi Creek, a partly perennial stream of the Hawkesbury-Nepean catchment, is located in the Central Tablelands and Blue Mountains regions of New South Wales, Australia.
A slot canyon is a long, narrow channel or drainageway with sheer rock walls that are typically eroded into either sandstone or other sedimentary rock. A slot canyon has depth-to-width ratios that typically exceed 10:1 over most of its length and can approach 100:1. The term is especially used in the semiarid southwestern United States and particularly the Colorado Plateau. Slot canyons are subject to flash flooding and commonly contain unique ecological communities that are distinct from the adjacent, drier uplands. Some slot canyons can measure less than 1 metre (3 ft) across at the top but drop more than 30 metres (100 ft) to the floor of the canyon.
The Humboldt Botanical Garden is a 44.5 acres botanical garden located south of Eureka, California, United States. The Garden is near the South Bay portion of Humboldt Bay on the north side of the College of the Redwoods. Grading and site preparation began in August 2003. Featuring views of Humboldt Bay and the Pacific Ocean, the garden opened in 2006, with more development completed by 2008.

The Australian Botanic Garden Mount Annan is a 416-hectare (1,030-acre) botanical garden located in a hilly area of the southwestern Sydney suburb of Mount Annan, between Campbelltown and Camden, New South Wales. It is the largest botanical garden in Australia, specializing in native plants, with a collection of over 4000 species. Officially opened in 1988, it was known as Mount Annan Botanic Garden, until 2011.

The National Arboretum Canberra is a 250-hectare (620-acre) arboretum in Canberra, the national capital of Australia, created after the area was burned out as a result of the Christmas 2001 and 2003 Canberra bushfires: The Himalayan Cedar forest lost about one third of its trees, and the commercial Radiata Pine plantation was burned out, allowing the arboretum to be created.
