Long Term Intervention Monitoring (LTIM) Project - Stream Metabolism & Water Quality

The Stream Metabolism and Water Quality Basin Matter seeks to evaluate the influence of Commonwealth environmental water on two key ecological processes—primary production and decomposition—which have a profound effect on ecosystem character and condition. \r\n\r\nThe CEWO’s LTIM Project examined the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and assisted the CEWO to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation was focused in seven Selected Areas: the Junction of the Warrego and Darling rivers, Gwydir river system, Lachlan river system, Murrumbidgee river system, Edward/Kolety-Wakool river system, Goulburn River and Lower Murray River. These areas will continue to be monitored through the CEWO’s Monitoring, Evaluation and Research (MER) Program. \r\n\r\nData collected by monitoring at Selected Areas is used to evaluate local outcomes from watering and also contributed to the analysis and evaluation of Basin Plan objectives.\r\n\r\nStream metabolism data was collected over the duration of the LTIM Project from 2014-15 to 2018-19 in six Selected Areas* (Edward/Kolety-Wakool, Lachlan, Goulburn, Murrumbidgee, Warrego-Darling and Lower Murray).\r\n\r\n*Stream metabolism is not a Category 1 indicator in the Gwydir Selected Area.\r\n\r\nPlease refer to the Murray-Darling Basin LTIM Project: 2018-19 Basin-scale evaluation of Commonwealth environmental water – Stream Metabolism and Water Quality Report for the detailed method on data used for evaluation. \r\n\r\n###Acknowledgement\r\n\r\nThe Commonwealth Environmental Water Office acknowledge the First Nations peoples as the Traditional Owners and Custodians of the lands, waterways and skies of the Murray-Darling Basin. We thank them for their knowledge and science and respect their continuing connection to culture and Country and the values reflected in these data.\r\n\r\n

本数据集为河流代谢与水质流域项目（Stream Metabolism and Water Quality Basin Matter），旨在评估联邦环境水对两类关键生态过程——初级生产与有机质分解——的影响，二者对生态系统的特征与状态均具有深远作用。

联邦环境水办公室（Commonwealth Environmental Water Office, CEWO）牵头实施的LTIM项目，旨在评估联邦环境水对2012年流域计划（Basin Plan）环境目标的贡献，并协助CEWO论证环境效益、自适应管理所持环境水资源。本次监测与评估工作聚焦七个选定区域（Selected Areas）：沃雷戈河与达令河汇流区、吉德河（Gwydir）水系、拉克兰河（Lachlan）水系、默伦比奇河（Murrumbidgee）水系、爱德华/科莱蒂-瓦库尔河（Edward/Kolety-Wakool）水系、古尔本河（Goulburn River）及下默里河（Lower Murray River）。上述区域将通过CEWO的监测、评估与研究（Monitoring, Evaluation and Research, MER）项目持续开展监测。

在选定区域采集的监测数据，既可用于评估环境补水的本地环境效益，也可为流域计划目标的分析与评估提供支撑。

本LTIM项目实施周期为2014-15财年至2018-19财年，期间在六个选定区域*中采集了河流代谢数据，覆盖区域包括爱德华/科莱蒂-瓦库尔河、拉克兰河、古尔本河、默伦比奇河、沃雷戈-达令河及下默里河。

*注：吉德河选定区域内，河流代谢不属于一级监测指标。
