Pictorical language of Pablo S. Herrero is linked to the code of plant forms. Trees and forests, both murals and paper, are the vehicle to show the relationship between the dynamic and the static, individual and community, sustainability and resistance. His activity as a muralist, usually at off-center and marginal spaces, take the suburbs as a paradigm of the rejection that the city causes to large parts of itself. On the other hand, focuses his work also in rural areas. He has developed projects in public space in Spain, Portugal, France, Italy, Slovakia, Poland, Norway, U.S.A., Uruguay, Argentina and Cuba.
