Before plantation of exoticspecies in vast areas , they must be tested in small regions . In this research , it was surveyed ecological effects of A trip lexcanescens . Other researches were done on A trip lex canescence by other Iranian researchers ( Table １ ) . Present study surveyssome ecological effects in A trip lex canescens in land reclamation . There are different opinions about A . canescens positive andnegative effects on the planted areas environment and vegetation . Some studies dedicate that A . canescens planting has lead topositive results in the degraded rangelands , while , others refer to its negative results . Table １ shows desirable and undesirableresults of A . canescens planting in Iranian rangelands .Table 1 E f f ects o f A . canescens p lanting on soil and vegetation p roperties .Source of data Study area Summary of resultsKhalkhali ( １９９７ ) Shahryar and Gonbad‐e‐KavoosCover percentage has decreased in planted area compared to control area ; Higher diversity inplanted area ; Low nutrition levels in planted areaNaseri ( １９９６ ) Jupar‐Kerman Great number of brushes in control area ; More production in control area ; Smaller coverpercentage in planted areaT here was no difference between pH and EC in two areas ; OM decreases in planted areaNaseri ( １９９８ ) Kabutarkhan‐Rafsanjan Relatively equal number of brushes per area unit in both areas ; More production in controlarea ; Larger cover percentage in control area ; T he same diversity on both areasNo different between N , P . , K , Na , pH , EC , OM , clay and sand two areasAbbarik‐Gonabad Smaller density and cover percentage in planted areaNo difference between PH and EC in two areas ; OM decreases in control areaAbbas‐Abad Mashhad A decrease was observed in mentioned species density and cover percentage in planted area ;Increase of H ultemia persica was considerable in planted areaChah Norooz‐NeishabourDecrease of S tip a lassiginana density in planted areaChalak Haghighi( ２０００ )Kazeroon‐e‐Fars Presence of class I species has decreased in planted area due to favor created microclimate ;Increase of ％ OM in planted areaHenteh ( ２００２ ) Aghzi Gang Zarand Vegetation properties showed bet ter condition in planted area ; N , P , K , pH , EC ,％ OM ,pH , EC and K have higher levels in planted area compared to control areaResults and discussion Regarding Table １ results , it is clear that A . canescens and A . lenti f ormis planting contain both positiveand negative effects on soil and vegetation characteristics of the planted areas . The kind of effects ( positive and negative) ismainly influenced by planted area conditions and management . Cutting the aerial tissues ( sources of salinity in A trip lex ) aslivestock forage and animal grazing in a season with the least leave and seed falling ( which increase soil salinity ) are the twofavor practices that management should apply in order to prevent soil salinity due to A trip lex planting .To reduce animals illness due to A trip lex grazing , suitable grazing season observance using supplementaries and intercroppingis necessary . Chisci et al (２００１ ) states that cultivating A trip lex with legumes produces high quality forage . Totally , a goodmanagement is needed to cultivate A . canescens in degraded rangelands in arid and semi arid environment in order to get idealresults . This species can be referred as a pioneer species which approves the condition of planted area , sequently can be used inreclamation of degraded ranges or arid environments .ReferenceChalak Haghighi S .M . , ( ２０００ ) .
