ItemNo Preview AvailableToward Interspecies Art and Design Prosthetic Habitat-Structures in Human-Owl Cultures(MIT PRESS, 2022-08-01)Abstract Urbanization severely reduces opportunities for nonhuman habitation and undermines nonhuman subjectivities, aesthetic experiences, behaviors, traditions, and cultures. In response, humans need to reimagine cities as places for interspecies cohabitation. In this article, a team of architects and ecologists demonstrates that such reimagination depends on the cultural behaviors of multiple species. The authors illustrate the implications of this dependence by designing and discussing nesting structures for the powerful owl (Ninox strenua). The project shows that prosthetic habitats can serve as useful provocation for thinking about interspecies cultures. The authors use this work to propose productive avenues for further research.

The cavities that occur in these trees provide shelter and nesting sites for many species but can take centuries to develop. Artificial cavities, including nest boxes and carved logs, offer an increasingly important conservation response. However, current methods of designing, manufacturing and deploying such habitats have constraints that limit innovation, feasibility and effectiveness. In response, this article aims to provide new and broadly useable methods that can improve the design of habitat structures for cavity‐dependent animals. To address the shortcomings of existing methods, we develop an approach that uses computer‐aided design techniques of generative and parametric modelling to produce structures that satisfy stakeholder needs, computer‐aided manufacturing techniques of 3D printing and augmented‐reality assembly to build functional prototypes, and computer‐assisted techniques of laser scanning and data‐driven design to support installation, monitoring and iterative improvement of designs. We demonstrate this approach through a case‐study project that designs and instals habitat structures for the powerful owlNinox strenua, a cavity‐dependent and threatened bird. Through a comparison with existing methods, our pilot study shows that computer‐aided design and manufacturing can provide novel and useful approaches to develop artificial habitat‐structures. Computer‐aided design finds geometries that approximate the complex characteristics of natural tree cavities and automatically produces new versions to suit diverse sites or species. Computer‐aided manufacturing integrates materials that match the performance of naturally occurring habitat structures and facilitates the assembly of complex geometries by non‐experts. Computer‐assisted techniques produce precisely fitting and easy‐to‐instal designs, which support gradual improvement through ongoing prototyping and evaluation. These capabilities highlight how advanced design techniques can improve aspects of artificial habitat‐structures through geometric innovation, novel construction techniques and iterative exploration. Significantly, computational approaches can result in designs that can perform well, are easy to construct and instal and are applicable in many situations. Our reusable workflow can aid in the tasks of practical conservation and support ecological research by effectively negotiating the needs of both humans and target species.

ItemNo Preview AvailableInterspecies Cultures and Future Design(V&R unipress, 2022-04-11)This article introduces the notion of interspecies cultures and highlights its consequences for the ethics and practice of design. This discussion is critical because anthropogenic activities reduce the abundance, richness, and diversity of human and nonhuman cultures. Design that aims to address these issues will depend on interspecies cultures that support the flourishing of all organisms. Combining research in architecture and urban ecology, we focus on the design of urban habitat-structures. Design of such structures presents practical, theoretical, and ethical challenges. In response, we seek to align design to advancing knowledge of nonhuman cultures and more-than-human justice. We present interspecies design as an approach that incorporates human and nonhuman cultural knowledge in the management of future habitats. We ask: what is an ethically justifiable and practically plausible theoretical framework for interspecies design? Our central hypothesis is that the capabilities approach to justice can establish goals and evaluative practices for interspecies design. To test this hypothesis, we refer to an ongoing research project that aims to help the powerful owl (Ninox strenua) thrive in Australian cities. To establish possible goals for future interspecies design, we discuss powerful-owl capabilities in past, present, and possible future situations. We then consider the broader relevance of the capabilities approach by examining human-owl cultures in other settings, globally. Our case-study indicates that: 1) owl capabilities offer a useful baseline for future design; 2) cities diminish many owl capabilities but present opportunities for new cultural expressions; and 3) more ambitious design aspirations can support owl wellbeing in cities. The results demonstrate the capabilities approach can inform interspecies design processes, establish more equitable design goals, and set clearer criteria for success. These findings have important implications for researchers and built-environment practitioners who share the goal of supporting multispecies cohabitation in cities.

ItemAn Artificial Intelligence Agent That Synthesises Visual Abstractions of Natural Forms to Support the Design of Human-Made Habitat Structures(Frontiers Media SA, 2022-03-17)Biodiversity is in a state of global collapse. Among the main drivers of this crisis is habitat degradation that destroys living spaces for animals, birds, and other species. Design and provision of human-made replacements for natural habitat structures can alleviate this situation. Can emerging knowledge in ecology, design, and artificial intelligence (AI) help? Current strategies to resolve this issue include designing objects that reproduce known features of natural forms. For instance, conservation practitioners seek to mimic the function of rapidly disappearing large old trees by augmenting utility poles with perch structures. Other approaches to restoring degraded ecosystems employ computational tools to capture information about natural forms and use such data to monitor remediation activities. At present, human-made replacements of habitat structures cannot reproduce significant features of complex natural forms while supporting efficient construction at large scales. We propose an AI agent that can synthesise simplified but ecologically meaningful representations of 3D forms that we define as visual abstractions. Previous research used AI to synthesise visual abstractions of 2D images. However, current applications of such techniques neither extend to 3D data nor engage with biological conservation or ecocentric design. This article investigates the potential of AI to support the design of artificial habitat structures and expand the scope of computation in this domain from data analysis to design synthesis. Our case study considers possible replacements of natural trees. The application implements a novel AI agent that designs by placing three-dimensional cubes – or voxels – in the digital space. The AI agent autonomously assesses the quality of the resulting visual abstractions by comparing them with three-dimensional representations of natural trees. We evaluate the forms produced by the AI agent by measuring relative complexity and features that are meaningful for arboreal wildlife. In conclusion, our study demonstrates that AI can generate design suggestions that are aligned with the preferences of arboreal wildlife and can support the development of artificial habitat structures. The bio-informed approach presented in this article can be useful in many situations where incomplete knowledge about complex natural forms can constrain the design and performance of human-made artefacts.
