This article describes how land settlement policies over a period of 100 years and shrub regeneration in parts of the poplar box (Eucalyptus populnea) lands in New South Wales have had and will continue to have a major influence on the economics of grazing properties in the region. Choise of animals offers few options, but there are many methods of improving productivity which may be applicable to a particular property; their feasibility is being tested in a pilot rehabilitation scheme which is described.

Eucalyptus Populnea

Eucalyptus populnea Eucalj'ptus populnea (poplar or bimble box) can be controlled by ringbarking, mechanical pulling and by direct chemical appiication; fire alone has little effect. The initial ringbarking usually kills only a small percentage of trees, but repeated removal of the coppice growth leads to a complete kill. Mechanical pulling under favourable soil moisture conditions can remove many of the fignotubers from the ground and Little regrowth occurs, but in dry soils the trees break off at or near ground level and profuse re- growth occurs from the broken stumps. Chemical injection treatment, using the picloram compounds or 2,4,5-T, is probably the most economical method and high percentage kills can be obtained under all seasonal conditions. Of the shrub associates of poplar box, Eremophila mitchellii can be effectively controlled by basal stem sprays of 1.0% butyl 2,4,5-T in diesel distillate, whilst shrubs such as Cassia nemophila, C. artemisioides and Acacia deanei have been shown to be suscep- tible to fie under suitable fuel loads. Other important shrub species have reacted in varying degrees to both chemical and fue treat- ment.

Eucalyptus Populnea

Information on soil changes under various forms of land use in poplar box (Eucalyptus populnea) lands on solodic soils is summarized and generalizations on the effects of management practices on the soil resource are made. The implications of the results for land use are considered and problems seen as requiring further research are outlined. Crazing by domestic livestock results in soil compaction which, through decreasing the infiltration rates, causes an increase in the surface run-off of water. These effects are enhanced by the killing of trees, and the associated changes in soil water content profiles are accompanied by changes in the distribution of soluble soil salts. Scalds develop in some areas. Tnese deleterious changes are reversed where there is shrub growth and livestock are excluded. The reasons for the development and persistence of scalds require further elucidation. In particular, the conditions requited for the recruitment of grass and shrub species, and the relative importance of the various pathways for salt movement in these systems, should be defined.

The germinable soil seed bank of a grassy Eucalyptus populnea F.Muell, open woodland was investigated in relationship to distance from water (away from a bore-drain) on North Yancho Station, near Bollon in southern semi-arid Queensland. The germinable soil seed bank was both diverse and abundant, 69 taxa of seedlings being identified to species and 2 more to genus. A mean density of 13 207 ± 4160 seeds m-2 was recorded, with over 80% of the seed being from the annual forbs Crassula sieberana (Schultes & J.H.Shultes) Druce, Wahlenbergia tumidifructa P.J.Smith and Dysphania gomulifera (Nees) Paul G.Wilson. Most common species showed spatial variation in their germinable seed density with relation to distance from water, resembling the patterns previously reported by other authors for standing vegetation under stocking pressure gradients.

The diet of feral goats was recorded by direct observation in a shrub-dominated Eucalyptus populnea woodland between Nyngan and Bourke, N.S.W., on 7 sampling occasions over 2 years. Different nutritional opportunities were provided by the effects of rainfall on 4 contrasting grazing treatments. The goats foraged evenly over the paddocks and encountered most foods with the same frequency as they occurred. With unlimited quantities of forage available the goats spent 63% of their time grazing and only 28% browsing. Most browsing took place under dry conditions when pasture quality was low. When forage was in short supply the goats accepted some shrubs not normally eaten, and these plants died; other woody plants were consumed erratically or not at all. Acacia aneura was the only woody plant which was both palatable and resilient to goat browsing. Goats mostly ate the same plant species as sheep and with the same preference, but tended to eat more browse and less forbs than sheep in dry times. The browse consumed was principally the same as consumed by sheep, demonstrating sequential competition for dry-season fodder. Goats demonstrated a potential for overgrazing in dry times, indicating that stocking rates must be adjusted at such times to avoid pastures becoming extinct.

Land clearing in Queensland is often practised to enhance pasture production, and hence, increase financial returns from beef production. The benefits of clearing have been quantified in terms of short-term gains in pasture yield but have not adequately accounted for possible medium- or longer-term impediments that may be attributed to clearing. Therefore, impacts of clearing and the subsequent sowing of exotic grasses such as Cenchrus ciliaris L. on pasture composition and production were studied. To achieve this, paired sites were selected representing cleared and uncleared pastures across three different times since clearing (i.e. 5, 11–13 and 33 years since clearing) for the three dominant tree communities of central Queensland (i.e. Eucalyptus populnea F.Muell. (poplar box), E. melanophloia F.Muell. (silver-leaved ironbark) and Acacia harpophylla F.Muell. ex. Benth. (brigalow)). The results demonstrated that species diversity declined with clearing and sowing of exotic pastures. Species diversity and pasture production were negatively related. Although pasture yield was 2–3 times greater 13 years after clearing of E. populnea and A. harpohylla, the gains in pasture yield were not consistent over time, yields being only 1.5 times greater after 33 years of clearing. In E. melanophloia, an increase in the yield of only 1.5–1.8 times occurred 5 years after clearing compared with uncleared pastures, whereas 33 years after clearing, yield was 3/4 of that in uncleared pastures. The initial gains in pasture yield were accompanied by a loss of plant diversity that may affect ecosystem functions such as nutrient cycling or soil mineralisation, and the longer-term production gains.

Experiments at Talwood, south-western Queensland, showed that mechanical penetration of the bark at the base of the trunk and simultaneous injection with 2,4,5-T effectively killed mature single stemmed trees of Eucalyptus populnea (Bimble or Poplar Box). The method gave similar results in autumn, spring, and summer. The butyl and butoxy ethanol esters were seemingly equal in effect, and emulsions in water gave results comparable with solutions in diesel distillate. All injections were made into cuts two inches wide and one inch apart, with an average of 7.5 C.C. being injected into each cut. All concentrations of 2,4,5-T (1, 2.5, and 4 per cent active ingredient) gave good results, but the higher rates produced high percentage kills more consistently than the 1 per cent level. The addition of 0-phthalic acid to the water and of its dimethyl ester to the oil based treatments appeared to increase the rapidity of action but did not increase the percentage of trees killed at the lower concentrations. Picloram (Tordon 22K), applied in January 1964, killed all trees treated with both 0.5 and 1 per cent concentrations. This compound is being tested at lower concentrations and fewer injections per unit circumference.
