Bladder Saltbush Regeneration, 1970, 1983 and 1987. VIS_ID 4119, 4120, and 4121

This study reviews the distribution of healthy bladder saltbush on the Riverine Plain of south-east Australia towards the end of 1986, as well as the characteristics of regeneration following the saltbush dieback of 1977-83. The area of bladder saltbush increased by 53 percent, from 0.53 to 0.81 million ha, in the period 1983-86. A further 0.32 million ha, which previously supported saltbush, failed to regenerate. Variations in the pattern and progress of regeneration were closely related to variations in soil type and the effects of pre- and post-dieback grazing. Although the cause of dieback remains unknown, it would appear that much of the decline in the distribution of bladder saltbush could be attributed to post-dieback mismanagement of affected stands.\r\nThe dataset consists of the report and one map showing bladder saltbush regeneration 1987.\r\nThis dataset is related to the Bladder Saltbush Dieback dataset.

本研究回顾了1986年末澳大利亚东南部河滨平原上健康膀胱滨藜（bladder saltbush）的分布状况，以及1977-1983年膀胱滨藜衰亡事件后的植被更新特征。1983至1986年间，膀胱滨藜的分布面积增幅达53%，从0.53百万公顷增至0.81百万公顷；另有0.32百万公顷曾为膀胱滨藜适生区的区域未能完成自然更新。植被更新的格局与进程差异，与土壤类型变异、衰亡前后的放牧干扰均密切相关。尽管目前膀胱滨藜衰亡的成因仍未明确，但现有分析显示，膀胱滨藜分布范围大幅缩减的很大一部分原因，可归因于衰亡事件发生后对受影响斑块的不当管理。
本数据集包含该研究报告，以及一张展示1987年膀胱滨藜更新状况的专题地图。
