Noosa Catchment

The Noosa River Catchment, with an area of some 784 sq. km., is consisted of six major sub-catchments, from north to south:

  • Teewah Creek Catchment
  • Upper Noosa River Catchment
  • Lake Cootharaba - Kin Kin Creek Catchment (pictured here)
  • Lake Cooroibah Catchment
  • Lower Noosa River Catchment
  • Lake Weyba Catchment

Field Data Collection: Video Recording

Maps and data will be prepared from raw data collected by NICA community volunteers.

Community volunteers video the shoreline from a boat running parallel to the coastline approximately 25 m from the shore using a Sony Handycam. A GPS will be used to record latitude and longitude every 3 seconds. Both the GPS and Handycam are set to the exact same time. Noosa inland aerial view Aerial view of the inland Noosa River system.

During videoing, volunteers will be required to make voice notes on their personal observations, such as bird life and anecdotal stories relevant to the estuary or coastline. Field notes, including start times, weather conditions and tides were recorded in an observer diary. The digital still camera was used to record action shots and establish photo-point monitoring sites for future reference. Upon completion, the video, GPS track, still photos and observer diaries are sent to the MangroveWatch Hub for analysis.

Video Analysis

At the Hub, videos are analysed by post-graduate student volunteers. Each video was assessed as a continuous point intercept transect of the shoreline. Video of the shoreline is reduced to 1 second frame .jpg image files. The time of the video and GPS is used to match each frame to a specific GPS location. Each frame that matches a GPS position is used as a point along the transect. Specific environmental health features are recorded for each image point.

Criteria for Assessment

The SVAM is used to assess the following parameters;

  • Habitat Features
  • Shoreline Habitat Type.
  • Mangrove Vegetation height and density.
  • Mangrove Dominant Species.
  • Mangrove Condition – Dieback extent and frequency.
  • Fallen Tree frequency.
  • Physical Damage (Natural and Human related)
  • Physical Features
  • Bank Substrate
  • Bank Condition
  • Bank Slope
  • Walls and Hardened banks
  • Built Structures.

Report Card

Data collected from the video analysis is used to generate a condition score for the Noosa River estuary and shoreline. The condition score grades the overall bank habitat condition of the shoreline and relates to vegetation biomass, vegetation condition, bank erosion, slope and bank modification. Bank habitat condition is graded as Excellent, Very Good, Good, Requiring Improvement, Poor and Very Poor. Condition Scores are mapped using ArcGIS 9.3 and will be presented as a publically available estuary report card – See Burnett River exemplar Report Card.

Community Volunteers

A key feature of MangroveWatch is its close partnership between community volunteers and scientists from the James Cook University’s Mangrove Hub. Together they are systematically recording basic data as video and still imagery for assessments of estuarine habitat health.

Armed with expert support, training and advice, MangroveWatch volunteers in key regions are actively contributing to the monitoring of local estuaries and shorelines. An important goal in this phase of the program is to develop a network of like minded groups with the aim of producing public documents that describe important issues affecting local estuaries and mangroves, and their overall health.

Donations & Sponsorships

MangroveWatch Ltd is a registered charitable company in Australia. To achieve its goals and those of community participants, the program relies on funding and sponsorships to keep things going.

Donations and Sponsorships will be acknowledged on this site.

We need support for:

  • Community volunteers for small vessel hire and fuel
  • Field kits - costing up to $AUD3,000 each
  • Promotional items and awards such as T-Shirts and hats
  • Website maintenance
  • Computers and support for shoreline assessments by the Mangrove Hub
