Enhancing Pollinator Populations in Restored Prairie Habitats 2007 Accomplishments
... Restoring native habitats, such as tallgrass prairie, requires more than plants; reconstruction of a complete ecosystem requires all the elements, including pollinators. Without proper pollinators, many native wildflowers will fail to reproduce. Restoring pollinator populations requires providing mo ...

Banksia brownii
Banksia brownii, commonly known as Feather-leaved Banksia or Brown's Banksia, is a species of shrub that grows in southwest Western Australia. An attractive plant with fine feathery leaves and large red-brown flower spikes, it usually grows as an upright bush around two metres (7 ft) high, but can also occur as a small tree or a low spreading shrub. First collected in 1829 and published the following year, it is placed in Banksia subgenus Banksia, section Oncostylis, series Spicigerae. There are two genetically distinct forms.B. brownii occurs naturally only in two population clusters between Albany and the Stirling Range in southwest Western Australia. In the Stirling Range it occurs among heath on rocky mountain slopes; further south it occurs among Jarrah woodland in shallow nutrient-poor sand. It is rare and endangered in its natural habitat, with all major populations currently threatened by Phytophthora cinnamomi dieback, a disease to which the species is highly susceptible. Other threats include loss of habitat, commercial exploitation and changes to the fire regime.Highly valued by Australia's horticultural and cut flower industries, B. brownii is widely cultivated in areas not exposed to dieback. It prefers a sheltered position in soil with good drainage, and must be provided with some moisture over summer.
