“…The ten most common plant species determined by the ranking technique of Scott & Maunsell (1974) A frequently used road runs along the northern side of the block, and a number of occasionally used station tracks cross the block. Water troughs were situated in the north-west and north-east corners; there are no natural streams or seepage areas.…”

Flocks of merino wethers or ewes varying in size from 20 to 2200 were observed from dawn until dusk for 77 days over three summers on an 850 ha block of undeveloped, semi-arid Festuca novae-zelandiae tussock grassland with an altitudinal range of 60 m.Group location, size, and activity were recorded at half-hourly intervals together with associated weather. Sheep dispersed at dawn, grazed during the morning (about 80% at anyone time), rested during the middle of the day (standing, lying, or in shade groups; total about 60%) and then grazed again in the late afternoon (about 80% grazing). Activities engaged in were determined principally by time of day and temperature. Grazing reached a maximum at 1O-15°C, and numbers lying increased with temperature. Shade group formation increased rapidly above a threshold of about 15°C, particularly under sunny conditions. Sheep showed a preference for the higher terraces. Groups formed during the morning grazing period, but were irregular in composition and showed no territorial behaviour. Sheep tended to graze into the wind, more so at higher temperatures and wind speeds. Drinking was rarely observed. The proportion of the block grazed in a day depended on flock size, being about 15% per day for a flock of 20 to about 60% per day for a flock of 1600. Grazing of small areas of developed pasture appeared to be a chance occurrence.

“…While the low legume content is a feature of New Zealand hill pastures (Suckling 1966), the indigenous tussock grasslands of the South Island are almost devoid of legumes and consequently are low producing in their natural state (Leamy et al 1974;McLeod 1974). Better legumes are therefore important to improve the naturally low soil N status (Scott & Maunsell 1974) and to directly transfer N to grasses and thus increase total forage production.…”

The roles of legumes in achieving sustainable farming on Longslip Station, Omarama - past, present, and future

The role of legumes for increasing pasture production and quality to ensure the long-term sustainability prospects for a high country sheep and cattle farm, with reference to options, impediments and future directions. The currently available pasture legumes have serious shortcomings in the face of drought, low soil fertility, aluminium toxicity and competition from Hieracium species. I describe a vegetation study in the Caucasian mountains in the search for more persistent, diverse, aluminium-tolerant and fertiliser-efficient pasture species. Keywords: caucasian clover, high country, Hieracium, oversowing and topdressing, sheep, sustainability, Trifolium repens, Trifolium trichocephalum

“…In a survey of grasslands in Canterbury Province, New Zealand, Connor & MacRae (1969) classified H. radicata as a 'widespread tussock grassland species'; it has a high frequency of occurrence (in 60-100% of all sampled sites) in fescue-tussock grassland (a short-tussock grassland where Festuca novae-zelandiae is the physiognomic dominant, along with Agropyron scabrum, Agrostis capillaris, Anthoxanthum odoratum and Poa colensoi), red-tussock grassland (a tall-tussock grassland where Chionochloa rubra predominates) and snow-tussock grasslands (a tall-tussock grassland dominated by Chionochloa flavescens and C. rigida), ranging from sea level to 1400 m. Connor & MacRae (1969), Grace & Scott (1974), Scott & Maunsell (1974), and Struik (1967) provide extensive lists of associated species in tussock grasslands of New Zealand. radicata was first recorded for New Zealand in 1864 by J. D. Hooker.…”

“…The shoots of H. radicata are eaten by a number of animals, both domesticated and wild, for example, sheep (Grace & Scott 1974;Scott & Maunsell 1974), pigs (Guthrie-Smith 1969), snowshoe hares (Radwan & Campbell 1968), slugs (Healy 1962), birds and ants (Disp. P1.).…”

Herbaceous perennial growing from hard, thickened, overwintering base (caudex); fibrous-rooted, but often with several enlarged roots, and appearing tap-rooted; leaves in a basal rosette, hispid with simple hairs, oblanceolate, toothed or pinnatifid, 3-25 cm long and 0.5-7 cm wide; stems 15-60 cm tall, usually several from each rosette, erect or ascending, usually forking, enlarged below the heads and bearing many small scale-like bracts, possessing a 'milky' latex; capitula 20-30(-40) mm wide, usually 6-9, terminating the branches; florets yellow, ligulate monoclinous and bisexual, the ligules surpassing the involucre and about 4 times as long as wide, the outer ones greenish or grey-violet beneath; involucre 18-25 mm high at anthesis, cylindricalcampanulate, up to about 25 mm in fruit, its bracts imbricate, dull green, glabrous or hispid; fruit an achene (Fig. 2(d)), orange or brown, body of the achene usually 4-7 mm long, from a little longer to more often much shorter than the slender beak, the prominent nerves and the lower part of the beak muricate; pappus plumose with two rows of hairs, those in outer row shorter and commonly merely barbellate.Considerable variability has been reported for H. radicata. European workers have recognized several subspecies, varieties and forms (Hegi Fl. ed.
