However necessary it is, the protection of nature in a urban space can´t be imagined in terms of a pre-established schedule. Places of living that witness the spontaneous appearance of an urban fauna and flora as well as their development are unpredictable. They are vagabond spaces and as such, their existence is likewise temporary. This kind of protection of nature stands a chance of coming to light only if a rethinking of contemporary urbanism takes place that will lead to its replacement with a dialectic alternation between construction and decay process.
