Riverina Plains Important Bird Area
The Riverina Plains Important Bird Area comprises some 10,668 km2 of agricultural grassland in the Riverina region of New South Wales, Australia. Much of the site lies roughly between Hay, Jerilderie and Hanwood, straddling, but with most of it lying south of, the Murrumbidgee River. It adjoins the Murrumbidgee Red Gums IBA. Birds The site has been identified by BirdLife International as an Important Bird Area (IBA) because it contains most of the habitat suitable for plains-wanderers in the Riverina. It also has good populations of other grassland birds, including brown songlarks, Australian pipits, banded lapwings and singing bushlarks, as well as the arid biome restricted inland dotterel The inland dotterel (''Peltohyas australis'') is an endemic bird of the arid Australian interior. It forms loose flocks in sparsely vegetated gibber plain and claypans in the day where it loafs in the shade and eats shoots of shrubs. It is most o ....BirdLife International. (2011). ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plains-wanderer
The plains-wanderer (''Pedionomus torquatus'') is a bird, the only representative of family Pedionomidae and genus ''Pedionomus''. It is endemic to Australia. The majority of the remaining population is found in the Riverina region of New South Wales. Description The plains-wanderer is a quail-like ground bird, measuring 15–19 cm. It is such an atypical bird that it is placed in an entire family of its own, Pedionomidae. The adult male is light brown above, with fawn-white underparts with black crescents. The adult female is substantially larger than the male, and has a distinctive white-spotted black collar. They have excellent camouflage, and will first hide at any disturbance. If approached too closely, they will run rather than fly, at which they are very poor. Females lay four eggs, which the male then incubates. Taxonomy It was formerly believed to be related to the buttonquails and thus placed in the gamebird order Galliformes or with the cranes and rail ...

Inland Dotterel
The inland dotterel (''Peltohyas australis'') is an endemic bird of the arid Australian interior. It forms loose flocks in sparsely vegetated gibber plain and claypans in the day where it loafs in the shade and eats shoots of shrubs. It is most often encountered at night when it forages on roads for insects. The relative remoteness of its habitat means that it is not well studied. The most detailed observations of the species were made by the South African arid-zone ornithology specialist Gordon Maclean in the 1970s. Alternate English names include Australian plover, inland plover, desert plover and prairie plover. Description The inland dotterel is a medium-sized plover with a distinctive cryptic plumage. Males and females are similarly sized: in length, a wingspan of a weight of , and a short bill . It is unlikely to be confused with any other species when found in its normal habitat. Its upperparts are a rich sandy buff, mottled with dark brown. The black band across the cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Singing Bushlark
Horsfield's bush lark (''Mirafra javanica'') is a species of lark which inhabits grassland throughout most of Australia and much of Southeast Asia. It is named for American naturalist Thomas Horsfield. Taxonomy and systematics The Horsfield's bush lark is one of 90 species of larks of the rather large and fairly diverse family, Alaudidae. They are small to medium-small passerines, usually with rather drab, brownish plumage. Predominantly an Old World family, the species are distributed widely across Europe, Africa, Asia and the Indian subcontinent but Horsfield's bush lark is the only species occurring naturally in Wallacea, New Guinea and Australia. The alternate shortened name "bush-lark" can also refer to many of the other species in the genus '' Mirafra''. The alternate name of "cinnamon bush lark" is also an alternate name for the flappet lark, and the alternate name of "singing bush lark" more commonly refers to the species of the same name, ''Mirafra cantillans''.

Banded Lapwing
The banded lapwing (''Vanellus tricolor'') is a small to medium-sized shorebird, found in small parties or large flocks on bare ground in open grasslands, agricultural land and open savannah. It is native to Australia and in the past considered as a game bird for hunting. Population estimate is 25 000 - 1 000 000. Other names include banded, black-breasted, brown flock and plain plover. Taxonomy Lapwings belong to the family Charadriidae (plovers) and sub-family Vanellinae. Biochemical evidence suggests that plovers are holophyletic, meaning that all modern plovers, and no other taxa, share the same common ancestor. It has been suggested that most plovers originated from the Southern Hemisphere and evolved under arid and semi-arid conditions. There are 25 extant species of lapwings. Africa has the most species of lapwings, while North America has none. Australia has two native species, the masked lapwing and the banded lapwing. The masked lapwing is split into ''Vanellus mile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Pipit
The Australian pipit (''Anthus australis'') is a fairly small passerine bird of open country in Australia and New Guinea. It belongs to the pipit genus ''Anthus'' in the family Motacillidae. It was formerly lumped together with the Richard's, African, Mountain and Paddyfield pipits in a single species: Richard's pipit, ''Anthus novaeseelandiae''.Many authors split the Australasian pipit further into two species: Australian pipit (''Anthus australis'') in Australia and New Guinea. Description It is a slender bird, 16 to 19 cm long, and weighs about 40 grams. The plumage is pale brown above with dark streaks. The underparts are pale with streaks on the breast. There is a pale stripe over the eye and dark malar and moustachial stripes. The long tail has white outer-feathers and is often wagged up and down. The legs are long and pinkish-brown while the bill is slender and brownish. It has a sparrow-like ''chirruping'' call and a drawn-out ''tswee'' call. Ecology It is ...

Brown Songlark
The brown songlark (''Cincloramphus cruralis''), also Australian songlark, is a small passerine bird found throughout much of Australia. A member of the family Locustellidae, this species is notable for sexual size dimorphism, among the most pronounced in any bird. It is a moderate-sized bird of nondescript plumage; the female brownish above and paler below, the larger male a darker brown. Taxonomy The brown songlark was described by Nicholas Aylward Vigors and Thomas Horsfield as ''Megalurus cruralis'' in 1827. John Gould placed it in the genus ''Cincloramphus'' in 1843, describing it as ''C. cantatoris''. However, the specific name of the former authors took priority. Along with most Old World Warblers, this species was formerly placed in Sylviidae sensu lato, but molecular phylogenetic studies demonstrated that this broad grouping is not a cohesive evolutionary lineage and warbler species were assigned to various families. An alternative generic name ''Cinclorhamphus'' is deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riverina
The Riverina is an agricultural region of south-western New South Wales, Australia. The Riverina is distinguished from other Australian regions by the combination of flat plains, warm to hot climate and an ample supply of water for irrigation. This combination has allowed the Riverina to develop into one of the most productive and agriculturally diverse areas of Australia. Bordered on the south by the state of Victoria and on the east by the Great Dividing Range, the Riverina covers those areas of New South Wales in the Murray and Murrumbidgee drainage zones to their confluence in the west. Home to Aboriginal groups including the Wiradjuri people for over 40,000 years, the Riverina was colonised by Europeans in the mid-19th century as a pastoral region providing beef and wool to markets in Australia and beyond. In the 20th century, the development of major irrigation areas in the Murray and Murrumbidgee valleys has led to the introduction of crops such as rice and wine grap ...
