  Tussock - Wikipedia, the free encyclopedia
Tussock may refer to a clump of a grass or the tuft of hairs on certain moths.
Also a matt of decaying roots and vegetation floating on a lake or pond.
In New Zealand tussock refers to a plant that is usually found in the harsh areas of the country, such as mountains.

 Methods for restoration of depleted tussock grasslands
Tussocks can also be established by dividing vigorously tussocks into clumps of 10+ tillers, planted in a nursery for a year and then transplanting.
He concluded that snow tussock species may not therefore have inherently poor seed set, as has sometimes been assumed, but despite their seasonal irregularity of flowering, seed production is always at risk of heavy attack by insects with very closely adapted host-specific biology.
On the basis of the classification that tussocks were species of slow growth habit (Moore 1956), O’Connor (1963) was not surprised by the lack of growth responses of snow tussock to fertiliser (nitrogen phosphorus, potassium and sulphur).

In Tussocks last show of the season she went to ring 1, where she jumped over a metre for the first time in competition.
At the first show she won the novice dressage test which was run as a separate class, and placed third overall in the combined dressage/jumping phase.
Tussock also went to the CD Dressage Spring Show and scored 58.89 for her novice test, placing her in the top third of the class, and was placed 4th in one of her Prelim tests.

 Terrestrial Ecoregions -- Cantebury-Otago tussock grasslands (AA0801)
Canterbury and Otago lie on the eastern side of the Southern Alps in the South Island of New Zealand; Canterbury to the north, and Otago to the south, divided by the Hawkdun Range and the Mackenzie Basin.
Tussock grasslands are threatened by exotic conifers, such as the lodgepole pine (Pinus contorta), while dryland environments are invaded by broom (Cytisus scoparius) and sweet briar (Rosa rubiginosa).
The Cantebury-Otago Tussock Savannas extend from the foothills of the Southern Alps to the east coast of the South Island, incorporating ecological regions and districts as defined by the New Zealand Department of Conservation (1987).

 Forest Health - Doublas Fir Tussock Moth - WSU - NRS EXT
They hatch as tiny, fl-headed caterpillars and finish as larvae about 1" in length, with four distinct tufts of white hair with red tips in the middle of the back, two "horns" of hair in front, and two tufts at the end of the abdomen, one of which may be reddish.
Tussock moths are favored by stands of high density, a high percentage of true fir and Douglas-fir, or many trees with a large crown diameter.
Defoliation by tussock moths is itself a predisposing factor for bark beetle infestation, particularly fir engraver and Douglas-fir beetle.

 DPIWE - Serrated Tussock WMP   (Site not responding. Last check: 2007-10-13)
Serrated tussock is a Weed of National Significance because of its potential to infest large areas of agricultural land across Australia and because it is hard to control.
These include practicing integrated serrated tussock control in pastures or crops likely to be harvested for sale or distribution, careful inspection of the product prior to sale or distribution and forgoing the sale and distribution of produce grown in areas where serrated tussock control has not been undertaken successfully.
For example, a group of Zone B landholders attempting to implement a serrated tussock management plan for their local area may report new occurrences of serrated tussock on municipal roads passing through their area, in order that these be targetted for control.

 Serrated tussock (Nassella trichotoma) - Weeds of National Significance - Weed Management Guide   (Site not responding. Last check: 2007-10-13)
Serrated tussock is a perennial grass that reproduces from seed.
Serrated tussock seedlings are usually outcompeted by other plants, but become competitive under conditions of drought or overstocking when more favourable pasture species are consumed by stock, leaving the less palatable serrated tussock.
Serrated tussock can germinate in response to rain at any time so it is vital to keep good pasture cover (at least 80%) and avoid overgrazing to prevent the weed taking hold.

 Tussock Moth Bulletin
In urban areas the tussock moth primarily is a pest of blue spruce, where it commonly causes top kill and sometimes even whole-tree mortality if not controlled.
Young tussock moth caterpillars are flish with very long body hairs, becoming ornamented with brightly colored tufts of hair as they grow larger.
Perhaps the artificial nature of these urban "forests," and the associated stresses on the trees, allows the tussock moth to survive at higher levels than is usually possible in the forest environment.

In urban areas the tussock moth primarily is a pest of Colorado blue spruce, where it commonly causes top kill and sometimes even whole-tree mortality if not controlled.

 Tussock Skink 
Male Tussock Skinks are smaller than females, having a maximum head and body length of 51 mm compared to the females at 58 mm.
Tussock skinks are remarkably well adapted to living amongst tussocks, moving their elongate bodies sinuously to disappear rapidly at the first sign of danger.
Male Tussock skinks are thought to live for up to four years, although females may live for as long as seven years.

 Tussock Moth Caterpillars in Florida
Tussock moth caterpillars are occasionally abundant and widespread in northcentral Florida.
Caterpillars of the whitemarked tussock moth, Orgyia leucostigma, are similar looking but are distinguished by their lighter body color and yellow spots.
These young caterpillars are easily recognized as tussock moths by the short "hair pencils" just behind the head, the tussocks beginning to form on the first abdominal segments, the sparse hairs along the body, and the brightly colored glands on the dorsum of abdominal segments 6 and 7.

 Broad-leaved snow tussock
Tussocks may be smaller with narrow leaves, where soil fertility is reduced or at higher altitudes.
Open tussock grasslands on sunny faces are associated with the common tussock grassland species, whilst Aciphylla colensoi, golden spaniard (Aciphylla aurea), mountain cotton daisy, Anisotome filifolia, Pterostylis australis orchids, and short tussock species are associated with mid-altitude semi intact grasslands on shadier faces.
Those broad-leaved snow tussock grasslands found in wetter locations, on, or to the west of the Main Divide are less likely to have been modified by human activities, although some have been depleted as a result of browsing by feral animals, such as hares and deer.

 DPIWE - Serrated Tussock
Serrated tussock is a perennial, tussock forming grass with a deep, fibrous root system, similar in general appearance to several of our native tussocks.
Because, at first glance, serrated tussock is so similar to other tussock grasses, it is frequently overlooked until it begins to flower, at which time it is most readily distinguishable.
Seed of serrated tussock is unlike the seed of any of the other tussock grasses with which it is likely to be confused (see illustration).

 Whitemarked tussock moth, MU Extension
Whitemarked tussock moth caterpillars (Orgyia leucostigma) are present from May to October.
Arising laterally on each side of the first thoracic segment (which is red) is a group (or pencil) of long fl hairs that point forward past the red head.
These hairs, often in a densely clumped "tussock" or a small or elongated brush (called a pencil) are found arising in specific locations, patterns and colors; they can be stinging or irritating (urticating) when handled or touched by people with sensitive skin.

Burning is still a practice being used in the management of copper tussock grassland in all of the zones of this study except Fiordland.
Some of the burnt tussocks were fenced to exclude hares from grazing the tussock regrowth.
Compared with unburnt tussocks there is no major increase in the rate of leaf elongation in the year after fire.

Permanently marked height-frequency vegetation monitoring sites in the Bain, Rock and Pillar, Lauder, and Eyre conservation areas, established at or about the time of their formal protection, were resampled after intervals of 5-6 years.
Removal of grazing by domestic stock aids recovery of the dominant tussock species, as indicated by data from monitoring tall- and short-tussock grasslands.
As the height and canopy cover of the tall tussock increased, there was a corresponding, although variable, decline in the diversity and biomass of native and naturalised inter-tussock plant species at most sites.
