Wetland Condition Assessment

Ecological condition assessments are used to track and report on the ecological trajectory of areas over time in response to management interventions such as environmental watering or natural events such as drought or flood.

Examples of wetland condition assessments carried out by Rakali Ecological Consulting include:

Index of Wetland Condition Assessments (2009 and 2010/11)Billabong-Wetland-Aggregate,-zone-1,-Tahbilk
[Client: Department of Sustainability and Environment]

A rapid-assessment method that measures the condition of natural, non-marine influenced wetlands in Victoria. Damien Cook was involved in the project management of approximately 300 wetlands across six catchment management regions, between 2009 and 2011.


Kerang Ramsar and other significant wetlands monitoring project (2014)
[Client: North Central Catchment Management Authority]Lake-Kelly-Samphire-Shrubland_4633

For this project wetland condition assessments and vegetation surveys were conducted at 19 wetlands around the Kerang region. Specifically the objectives of this project were to conduct Index of Wetland Condition biota assessments at 16 of these wetlands (7 of which were re-assessments), conduct baseline vegetation surveys at nine of the wetlands and establish permanent vegetation monitoring quadrats at eight of the wetlands. Pre-existing quadrats were resampled at three wetlands; McDonalds and Hird Swamps which had been dry when the quadrats were established and which were resampled because vegetation diversity had improved significantly due to flooding, and on the western edge of Third Marsh, where grazing exclusion plots had been established by Parks Victoria in 2008.


Wetland and Terrestrial Vegetation Condition Monitoring: Kerang Wetlands, Richardsons Lagoon and Leaghur State Park (2012)  [Client: North Central Catchment Management Authority]Black-Box-Wetland,-flooded-ps

Flora and fauna survey, EVC mapping, weed mapping, IWC and tree health assessments were carried out at these wetlands. Provided recommendations on vegetation and hydrological management of each wetland.



Vegetation surveys and condition assessments of Tang Tang and Red Gum Swamps and Lake Lyndger and Wandella (2014) [Client: North Central CMA]Tang-Tang,-Red-Gum-Swamp-Plains-Grassy-Wetland-Complex_1Tang-Tang

Many wetlands in North Central Victoria have had their hydrology altered, which has for some resulted in massive Red Gum death and loss of understorey plant species.  Loss of vegetation frequently means a loss or reduction in animals that rely on them.  The aim of this study was to monitor the plants and animals that persist at these wetlands, map the ecological vegetation classes (EVC’s), map distribution and species of weeds, measure the Index of Wetland Condition (IWC) and tree health.  This information was used to provide recommendations on vegetation, fauna and hydrological management of each wetland.


Vegetation surveys and condition assessments of Lake Meran (2014)
[Client: North Central Catchment Management Authority]Intermittent-Swampy-Woodland,-Swai-swai-and-Lotu-cren,-Lake-Meran

Flora and fauna survey, EVC mapping, weed mapping and IWC. Providing recommendations on vegetation, fauna and hydrological management of each wetland. Vegetation Quadrat Data Collection Project 2010/11 (2011) Two-hundred and ninety-eight vegetation quadrat surveys were undertaken throughout the Central East region of Victoria between April and June 2011. Detailed floristic and site data was routinely collected in poorly known or under-sampled vegetation types in remotely located Quadrat sites – predetermined by the DSE.

Wetland and terrestrial vegetation survey and condition assessment at First, Second and Third Reedy Lakes, Little Lake Charm, Scott’s Creek and Racecourse Lake (2013) [Client: North Central CMA]Intermittent-Swampy-Woodland,-drowned-and-Third-Reedy-Swamp

Rakali Ecological Consulting Pty Ltd was engaged by the North Central Catchment Management Authority on behalf of the G-MW Connections Project to assess the ecological values of six wetlands and surrounding lands in the Kerang Lakes Ramsar Site. These wetlands are currently subject to an investigation that is exploring the possibility of their removal from the irrigation conveyance system of the Torrumbarry Irrigation System (TIS). This would restore a more natural hydrological regime and lead to water savings throughout the catchment.

Lower and Mid Goulburn River Wetland Assessments (2011/2012)
[Client: Goulburn Broken Catchment Management Authority]

A study of wetland flora and fauna along the Goulburn River, including IWC assessments for the Goulburn Broken Catchment Management Authority.
