Drummond Nature Reserve
The Drummond Nature Reserve is an A class nature reserve 10 kilometres west of Bolgart, Western Australia. Named after the botanist James Drummond, the reserve has 439 species of vascular plants within its boundaries, including two rare and seven priority species. History In 1993 the land was purchased by the Mundaring district office of the Department of Conservation and Land Management and gazetted as an A class reserve. Prior to purchasing the land was uncleared freehold grazing land. Despite this use the land was in excellent condition, though evidence of grazing impact was visible in part of the eastern area of the reserve. The reserve was named after botanist James Drummond who lived in nearby Toodyay. Between 1841 and 1844 Drummond explored and collected specimens in the area which were part of his second collection. Topography and vegetation The Drummond Nature Reserve is constructed with a series of lateritic hills with spillway deposits plus a small outcrop of bedr ...

Acacia
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from '' Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent. There are 2 small stipules at the base of the leaf, but sometimes fall off as the leaf matures. The flowers are borne in spik ...

Eucalyptus
''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'' and ''Angophora'', they are commonly known as eucalypts or "gum trees". Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil Gland (botany), glands. The sepals and petals are fused to form a "cap" or Operculum (botany), operculum over the stamens, hence the name from Greek ''eû'' ("well") and ''kaluptós'' ("covered"). The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Many eucalypt species have adapted to wildfire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocotyle
''Hydrocotyle'', also called floating pennywort, water pennywort, Indian pennywort, dollar weed, marsh penny, thick-leaved pennywort and white rot, is a genus of prostrate, perennial aquatic or semi-aquatic plants formerly classified in the family Apiaceae, now in the family Araliaceae. Description Water pennyworts, ''Hydrocotyles'', are very common. They have long creeping stems that often form dense mats, often in and near ponds, lakes, rivers, and marshes, and some species in coastal areas by the sea. ;Leaves: Simple, with small leafy outgrowth at the base, kidney shaped to round. Leaf edges are scalloped.

Comesperma
''Comesperma'' is a genus of shrubs, herbs and lianas in the family Polygalaceae. The genus is endemic to Australia. It was defined by the French botanist Jacques Labillardière in his 1806 work ''Novae Hollandiae Plantarum Specimen''. The genus name is derived from the Ancient Greek words ''come'' ("hair") and ''sperma'' ("seed"), and relates to the seeds bearing tufts of hair. The genus is distributed over southern Australia, particularly in the southwest of Western Australia, where 19 species are found. 24 species have been described. The genus was classified in the tribe Polygaleae by Swiss botanist Robert Hippolyte Chodat in 1896. It was also considered a section of the genus '' Bredemeyera'' by van Steenis in 1968. This was not adopted widely, and a cladistic study based on morphology published in 1993 suggested they remain as separate genera. This analysis placed ''Comersperma'' basal to a group comprising the genera ''Polygala'', '' Monnina'' subg. ''Monninopsis'', '' N ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium The Western Australian Herbarium is the state Herbarium, situated in Perth, the capital of Western Australia. It houses a collection of more than 845,000 dried specimens of plants, algae, bryophytes (mosses, liverworts and hornworts), lichens, fu .... The herbarium's journal, '' Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have n ...

Eleocharis
''Eleocharis'' is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (''heleios''), meaning "marsh dweller," and χάρις (''charis''), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of ''Eleocharis'' species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation (in the tropical Andes). The genus itself is relatively easy to recognize; all ''Eleocharis'' species have photosynthetic stems but no green leaves (the leaves have been reduced to sheaths surrounding the base of the stems). Many species are robust, rhizomatously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trithuria
''Trithuria'' is a genus of small ephemeral aquatic herb that represent the only members of the family Hydatellaceae found in India, Australia, and New Zealand. Almost all described species of ''Trithuria'' are found in Australia, with the exception of ''T. inconspicua'' and ''T. konkanensis'', from New Zealand and India respectively.Dmitry D. Sokoloff, Margarita V. Remizowa, Terry D. Macfarlane, and Paula J.

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Dieback
Forest dieback (also "", a German loan word, ) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, and more. These episodes can have disastrous consequences such as reduced resiliency of the ecosystem, disappearing important symbiotic relationships and thresholds. Some tipping points for major climate change forecast in the next century are directly related to forest diebacks. Definition Forest dieback refers to the phenomenon of a stand of trees losing health and dying without an obvious cause. This condition is also known as forest decline, forest damage, canopy level dieback, and stand level dieback. This usually affects individual species of trees, but can also affect multiple species. Dieback is an episodic event and may take on many locations and shapes. It can be along the perimeter, at specific elevations, or dispersed throughout the forest ecosystem. Forest dieback present ...
