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.</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">ISI:000239465100004</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 069RETimes Cited: 2Cited Reference Count: 36Cited References: *DEP NAT RES MIN, 2003, LAND COV CHANG QUEEN *DEP NAT RES, 2000, LAND COV CHANG QUEEN *STAT ENV ADV COUN, 1996, AUSTR STAT ENV 1996 ASH AJ, 1998, J AGR SCI 2, V131, P211 BOULTER SL, 2000, NATIVE VEGETATION MA BRAAK CJF, 1998, CANOCO 4 SOFTWARE CA BURROWS WH, 1988, NATIVE PASTURES QUEE, P72 BURROWS WH, 1990, AGR SCI, V3, P19 BURROWS WH, 2002, TROP GRASSLANDS, V36, P202 DAEHLER CC, 1998, PAC SCI, V52, P220 FAIRFAX RJ, 2000, BIOL CONSERV, V94, P11 GRAHAM TWG, 1981, AUSTR J EXPT AGR ANI, V21, P109 GRAHAM TWG, 1985, P 15 INT GRASSL C KY, P640 HECTOR A, 1999, SCIENCE, V286, P1123 HENDERSON PA, 1998, SPECIES DIVERSITY RI ISBELL RF, 2002, AUSTR SOIL CLASSIFIC JACKSON J, 1998, AGROFOREST SYST, V40, P159 JACKSON J, 2001, AUST J AGR RES, V52, P377 JONES CE, 1996, NEW ZEAL J AGR RES, V39, P449 KAUR K, 2005, RANGELAND J, V27, P143 KENT M, 1992, VEGETATION DESCRIPTI LAWRENCE PA, 1988, C WORKSH SERIES, P23 MCINTYRE S, 2001, AUSTRAL ECOL, V26, P233 MCINTYRE S, 2003, J APPL ECOL, V40, P445 ROBBINS GB, 1984, THESIS U QUEENSLAND ROBBINS GB, 1985, P 15 INT GRASSL C, P1000 SANGHA K, 2003, THESIS CENTRAL QUEEN SANGHA KK, 2005, AUST J SOIL RES, V43, P51, DOI 10.1071/SR03152 SANGHA KK, 2006, J TROP ECOL 2, V22, P177, DOI 10.1017/S0266467405003020 SCANLAN JC, 1990, AUST J ECOL, V15, P191 SCANLAN JC, 2002, RANGELAND J, V24, P56 TILMAN D, 1996, NATURE, V379, P718 TILMAN D, 1997, SCIENCE, V277, P1300 VANCE ED, 1987, SOIL BIOL BIOCHEM, V19, P703 WIEGERT RG, 1964, ECOLOGY, V45, P49 WILSON JR, 1986, TROP GRASSLANDS, V20, P134Kaur, Kamaljit Midmore, David J.
