The website targets local authorities, volunteers, researchers, planners, developers, and non-government organisation.
It was launched on behalf of the Urban Regeneration & Greenspace Partnership, which promotes green-space initiatives and best practice.
Users can tap into green space projects and resources, best-practice guidance, case studies, evidence notes, toolkits and models.
A representative said the partnership aimed to identifying knowledge gaps and research priorities and develop a common research strategy across all stakeholders.
"We want to create a database and network of research, monitoring and evaluation covering local to national spatial scales." he said.
Partnership members include Forest Research and its parent, the Forestry Commission, Natural England, Defra and the Homes & Communities Agency.
