'Behind The Garden Gate' is a documentary about homegrown biodiversity and the challenges that come with it.
In the 1970s Guus Lieberwerth and friends cleared a patch
of agricultural wasteland in order to take care of rare and
endangered plants and animals.
Now, 50 years later nature is thriving within a hidden paradise
just five minutes away from a city centre, but even closer to systemic pressures and land developers.
