Abstract
The emerging recognition of the importance of urban habitat and wildlife for increasing biodiversity, driven partly by responses to climate change and urbanization, presents critical opportunities for urban biodiversity conservation and species recovery. However, effectively communicating these benefits to the public and policymakers remains a challenge for scientists and landscape architects with public perceptions, often shaped by diverse socio-cultural factors, serving as obstacles for garnering support. Our research explores innovative communication strategies through an intersectional analysis of planning and design communications and theory in museology and presents a structured approach in the use of charismatic species within interpretive studies to enhance public empathy and the potential for action. This research offers a valuable foundation for planning and design professionals, guiding their efforts to promote urban wildlife habitat and bridge the gaps between scientific knowledge and public advocacy.

Abstract
In recent decades, academic and professional research has increased understanding of the importance of city and landscape planners engaging with social and environmental justice issues, including contemporary inequities inherent in the planning, distribution, use, and access of public green and open spaces. However, there is a gap between this research centering equity and the planning, development, and implementation rate demonstrated by public agencies. In this article, we examine examples of emerging practice in the public park and recreation sector to understand the strategies and approaches public agencies are taking to provide equitable park and recreation systems. Our research identifies and analyzes 17 examples of North American public park and open space management agencies using equity-based planning frameworks to prioritize park investment and resource distribution. Equity-focused resource analysis is distinct because while it assesses budget and project-based funding distributions, it further incorporates assessments of historical allocations to understand better areas of under-investment and the evolving needs of different communities. As economic inequities become more pronounced, local governments, and other public institutions providing services to populations, are important in helping communities navigate changes. Our findings support the ongoing advancement of equity-driven planning and implementation for public park and recreation agencies by providing practical information on existing approaches to redress the impact of unfair patterns of under-investment.

Abstract
It is widely acknowledged that the quality of greenway landscape resources enhances the visual appeal of people. While most studies have evaluated visual perception and preference, few have considered the relationship between the distribution of greenways in relation to the proximity of water bodies such as lakes and rivers. Such an investigation requires an in-depth analysis of how to plan and design greenways in order to better enhance people's willingness to access and utilize them. In this research we propose specific color brightness and contour visual attraction elements to further discuss the quality of greenway landscape resources in the rapidly urbanizing Lake Taihu region of China. Specifically, we utilize a common method in fractal theory analysis called counting box dimension to calculate and analyze the sample images. The method generates data on fractal dimension (FD) values of two elements; the optimal fractal dimension threshold range; the characteristics exhibited by the maximum and minimum fractal dimension values in the greenway landscape; and the relationship between the two visual attraction elements allowing us to derive distribution of the greenway and water bodies. The results reveal that greenway segments with high values of the visual attraction element of color brightness fractal dimension (FD) are significantly closer to the lake than those subject to high values of the visual attraction element. Some segments are even close to the lake surface, which is because the glare from the direct sunlight and the reflection from the lake surface superimposed on each other, so that the greenway near the lake surface is also affected by the brightness and shows the result of high color brightness values. However, the greenway segments with high values of contour element FD are clearly more influenced by plants and other landscape elements. This is due to the rich self-similarity of the plants themselves. Most of the greenway segments dominated by contour elements are distant from the lake surface. Both color brightness and contour elements are important indicators of the quality of the visual resources of the Lake Taihu Greenway landscape. This reveals that the determination of the sub-dimensional values of color brightness (1.7608, 1.9337) and contour (1.7230, 1.9006) visual attraction elements and the optimal threshold range (1.7608, 1.9006) can provide theoretical implications for the landscape planning and design of lake-ring type greenways and practical implications for assessing the quality of visual resources in greenway landscapes.

In 2021, the College of Built Environments launched the CBE Inspire Fund to “inspire” CBE research activities that are often underfunded, but for which a relatively small amount of support can be transformative. The Inspire Fund aims to support research where arts and humanities disciplines are centered, and community partners are engaged in substantive ways. Inspire Fund is also meant to support ‘seed’ projects, where a small investment in early research efforts may serve as a powerful lever for future…

Abstract
Urban overheating significantly affects people's physical and mental health. The addition of street trees is an essential, economical, and effective means by which to mitigate urban heat and optimize the overall thermal environment. Focusing on typical street canyon clusters in Harbin, China, landscape morphology was quantified by streetscape interface measurements (sky view factor, tree view factor, and building view factor). Through ENVI-met simulations, the correlation mechanism between streetscape interface measurements and thermal environment was evaluated, and optimization methods for assessing the thermal environment of urban streets were proposed. The results revealed: (1) The thermal environment optimization efficiency of general street canyon types was greatest when street tree spacing was 12 m. At present, the smaller spacing has not been simulated and may yield better thermal environment results. The average decrease in temperature (Ta), relative humidity (RH) and mean radiant temperature (MRT) was 0.78%, 2.23%, and 30.20%, respectively. (2) Specific street canyon types should adopt precise control strategies of streetscape interface according to their types to achieve the optimal balance between thermal environment optimization and cost. (3) Streetscape interface measurements and thermal environment indexes show quadratic correlation characteristics, and are critical points for further investigation. The conclusions are more specific than previous research findings, which are of great significance for decreasing the urban heat island effect at the block scale, improving residents' physical and mental health, and improving the urban environment quality.

Abstract
Urban nature is typically managed through top-down, bureaucratic, and expert-driven approaches that tend to rationalize and simplify the interactions between humans and their surroundings. In the last few decades, there has been a significant push in cultural geography and the design disciplines to develop a relational ontology of urban nature, a perspective that emphasizes the hybrid connections between humans and nonhumans, built and unbuilt, social and natural. This perspective offers new and exciting ways of conceptualizing urban nature but it has not produced alternatives to conventional governance. In other words, thinking differently about urban nature has yet to produce different ways of interacting with it. In this paper we argue that civic environmentalism can enact a relational ontology by engaging urban residents in processes of democratic deliberation and action in the reworking of urban nature. We illustrate this approach with a case study of a community-led project to construct a pedestrian trail along an urban creek in Seattle, Washington. The example demonstrates how the concept of civic environmentalism embraces a relational perspective of urban nature, while also producing generative forms of political action.

Abstract
The success of urban stream restoration is often measured through biophysical attributes, or the progress towards restoration of a notionally intact section of landscape. What remains understudied is how success can be defined across social, economic, as well as ecological parameters. This research offers a narrative approach for urban restoration research that serves as a chronotope for untangling the biophysical and sociocultural complexities of the contemporary urban environment. The framework of this approach is presented through a case study of a recent stream restoration project in Seattle, Washington. The findings highlight the need for urban stream restoration processes to be grounded within a sociocultural context that is interdependent with biophysical conditions, and recommends measures of project success to include community, educational and participatory goals.
