浙江省有害植物种类、特点及防治

在多年调查的基础上,列出了浙江省有分布的90种有害植物名录,包括外来有害植物和土著有害植物。对有害植物进行了危害程度分类,并就严重危害种类和潜在威胁种类作了重点介绍。分析了浙江有害植物的特点,认为原产美洲的菊科Compositae与禾草类植物、水生植物及草质藤本植物极易造成严重危害。提出了治理有害植物的建议,特别强调对土著有害植物和阔叶丰花草Borreria latifolia,北美刺龙葵Solanum carolinense等潜在威胁种类应引起足够的重视。表1参39

Experimental assessment of release methods for the re-establishment of a red-listed galliform, the grey partridge (Perdix perdix)

Large-scale declines of grey partridges (Perdix perdix) since the 1980s have led to local extinctions in the species’ range. As part of a UK recovery programme, we aimed to identify the best methods of re-establishing grey partridges through releasing in areas of extinction where a suitable environment has been restored. In East Anglia and southern England we followed the fates and breeding success of radio-tagged (one site per region) and colour-ringed birds (12 sites per region) of individuals released using five different techniques. The average resighting rate after the first 6 months post-release was 20% for bantam-reared and artificially-reared fostered young, 7% for unfostered young, 10% for full-grown birds in autumn-released coveys and 9% for spring-released adults. For birds that survived the first 6 months, the percentage resighted after a second 6-month period averaged 35%. Across both regions, 65% of grey partridge losses were due to predation of which 58% were killed by mammalian predators and 37% by raptors. Of birds still alive during the breeding season, 88% established their breeding territory within 1.5 km of the release location. There were no detectable differences in breeding success between release methods, but the proportion of females with broods among released birds was a third lower than among wild birds. We recommend re-establishing grey partridges by first releasing autumn coveys, followed by fostering. However, where wild birds are still present, the conservation focus should be on habitat improvements and predation control.
