This project explores the interactions between ecologies and materials, particularly focusing on decaying materials and continual construction processes. At Nordmarken on Laeso Island, home to the rare alcon blue butterfly, the butterfly’s survival depends on specific flowers and ants with strict habitat requirements. By mapping these life cycles, we identified opportunities to enhance the ecosystem through timed interactions. Utilizing 3D printing with biomaterials and monitoring their erosion, we aim to create a responsive habitat that adapts to these interspecies timings. Our design includes a two-layer system: a sacrificial layer of seaweed and a structural core of bark or chitin. The project integrates human intervention at the macro level and insect-like robots at the micro level to maintain and adapt the habitat, encouraging ecological thriving. Six vignettes illustrate the intervention's lifecycle, from planting to full bloom and eventual erosion, ensuring a sustainable cycle for future plantings.
