B.  aA guide to the grasses of Xieng Khouang Province, Lao PDR and some notes on ecology of grazing lands in the province.  aSt. Lucia: CSIROc1998  a89p.  a(CSIRO. Genetic Resources Communication, 28).  aFrom an agro-ecological perpective, four zones are recognised in Xieng Khouang province, these being the plain of jars, the pine tree zone, the Upland zone and the Valley zone. The first three present opportunities for livestock development. Representative soils these three zones were analysed and a collection made of grasses occurring naturally in the three zone. A total of 68 species were collected and identified. Ilustrations and desciptions of these species are provided, together with a simple key their identification and notes on their ecology and use as forage. Opportunities for the future development of grazing lands in the province are briefly discussed.  aecology  agrasslands  agrazing  apastures  aCapim  aPastagem  aPastejo  aGraminea forrajeira1 aPHIMPHACHANHVONGSOD, V.1 aNAVAHA, S.1 aKORDNAVONG, P.1 aVELDKAMP, J.1 aSIMON, B.
