13 March 2019. Monday night at the landscape department and Henri Bava from the much praised office Agence Ter is lecturing, providing a fascinating exposé of their work and aim for enhanced responsivity between human and non-human agency. Theirs is an ‘agency’ that tries to consider territoriality, the powers played out by different actors, working through , stratifying rather than layering, that is with the relationship between qualitative and nourishing strata, rather than with structural accumulation. I am caught by Bava’s reference to trees and their functioning already in the Baroque garden as stratifiers, as temporal indicators, as boundary mediators, and hence, as political agents. And I am thinking along my own political ecological aesthetic lines. Trees are not innocent, not neutral. But they are not obedient either.
