Ecotherapy for Carers is a joint initiative by Villa Maria and the People & Parks Foundation and will run for four sessions in the Dandenong Ranges National Park from Thursday.

A 2006 report by the foundation found that participants in its Feel Blue Touch Green project experienced a calming effect and reduced daily stress levels from connecting with nature.

Studies indicate that while one in five people will experience depression, the risk of depression for a person caring for an unwell loved one can be higher.

Villa Maria's mental health resource consultant Jessica Taylor said difficulties facing carers included isolation, financial problems and the burden of care.

Ecotherapy for Carers will run for four two-hour sessions in the Dandenong Ranges national park, and will include learning about the history of the Dandenong Ranges, gardening, relaxation and meditation and art activities.

A nominal $5 fee for each session applies.
