This paper examines how humans shape landscapes through design and restoration, reflecting changing values over time. These values, often unstated, influence how landscapes are planned and managed. Current concerns such as biodiversity and climate resilience represent just one phase in an ongoing cycle of evolving values in landscape design. By understanding and reflecting on these values, practitioners can consciously choose which ones to prioritize in their projects. This approach empowers designers and ecologists to address current challenges effectively and adapt to future environmental changes and societal needs.

At Glenthorne, we tested a method to restore native grasslands using soil solarisation, originally developed for horticulture and now applied in ecological restoration. This involves covering moist soil with clear plastic during summer to eradicate weed seeds. Our findings, published in Soil Research (doi:10.1071/SR23168), revealed that sunlight intensity, measured by the UV index, has a greater impact than ambient temperature on increasing soil temperature—a critical factor for successful solarisation. This understanding allows land managers to optimize treatments by scheduling based on predictable sunlight intensity, which varies predictably over months to years. This contrasts with ambient temperature, influenced by daily weather changes. This insight promises to enhance the effectiveness of native grassland restoration efforts at Glenthorne and similar sites.
