Environmental Monitoring
At the heart of Project Twin Streams is a desire to improve the quality of our streams. To ensure we are making progress, Project Twin Streams carries out two strands of environmental monitoring: Pressure-State-Response (PSR) monitoring and Ecological Surveys.
PSR Monitoring
The Pressure-State-Response (PSR) model recognises that human activities such as residential growth put pressure on the environment, affecting the quality and quantity of natural resources. It provides a framework to gauge the cause and effects of environmental problems so that remedial steps can be taken.

Ecological Surveys
Ecological surveys use biological indictors such as the presence of birds, bats, lizards, geckos and insects together with fruiting and flowering phenology, vegetation structure and composition and animal pests to measure environmental conditions.
In addition, a number of community groups carry out Wai Care monitoring which means that they monitor and report stream water quality on a regular basis. The environmental monitoring campaign that began in 2003 has some noted improvements in certain locations.

Evaluation Framework
A formative evaluation was carried out on the initial phase of Project Twin Streams from 2003 to 2007. The evaluation framework used and the resulting evaluation report capture progress in that initial phase. Together these documented a clear platform from which to assess and plan the journey of Project Twin Streams as it evolves.

Sustainable Communities
Sustainable Communities was a three year project (part of Sustainable Cities) that ran from 2004 to June 2007. Project Twin Streams was selected as one of two demonstration projects. It provided additional resources which allowed Project Twin Streams to progress the social, economic and cultural outcomes of the project.
