Using remote sensing data within an optimal spatiotemporal model for invasive plant management: the case of Ailanthus altissima in the Alta Murgia National Park.

We tackle the problem of coupling a spatiotemporal model for simulating the spread and control of an invasive alien species with data coming from image processing and expert knowledge. In this study, we implement a spatially explicit optimal control model based on a reaction-diffusion equation which includes an Holling II type functional response term for modeling the density control rate. The model takes into account the budget constraint related to the control program and searches for the optimal effort allocation for the minimization of the invasive alien species density. Remote sensing and expert knowledge have been assimilated in the model to estimate the initial species distribution and its habitat suitability, empirically extracted by a land cover map of the study area. The approach has been applied to the plant species Ailanthus altissima (Mill.) Swingle within the Alta Murgia National Park. This area is one of the Natura 2000 sites under the study of the ongoing National Biodiversity Future Center (NBFC) funded by the Italian National Recovery and Resilience Plan (NRRP), and pilot site of the finished H2020 project ECOPOTENTIAL, which aimed at the integration of modeling tools and Earth Observations for a sustainable management of protected areas. Both the initial density map and the land cover map have been generated by using very high resolution satellite images and validated by means of ground truth data provided by the EU Life Alta Murgia Project (LIFE12 BIO/IT/000213), a project aimed at the eradication of A. altissima in the Alta Murgia National Park.

Illegal Solid-Waste Dumping in a Low-Income Neighbourhood in South Africa: Prevalence and Perceptions.

Illegal solid-waste dumping (ISWD) is prevalent globally with adverse social and environmental impacts, particularly in poor communities. Understanding the extent, practices and perceptions of ISWD is needed to inform interventions. Using GIS techniques and household surveys, this study examined the prevalence of dumpsites, and perceptions of ISWD in a low-income neighbourhood of Komani, South Africa. A total of 120 dumpsites were encountered in green spaces, empty residential plots and street edges, suggesting illegal dumping of solid waste is widespread. More than half of the respondents (58%) disposed of household waste in undesignated sites or burnt it, attributing this to the non-collection of waste. Potential interventions suggested were largely technical, including regular collection of waste, and the provision of bins and plastic bags. The paper suggests approaches to addressing sustainable solid-waste management should consider the views of local communities, who are principal stakeholders in the solid-waste production and management mix.

Changes in Residential Greenspace and Birth Outcomes among Siblings: Differences by Maternal Race.

Growing research investigates the perinatal health benefits of greenspace in a mother's prenatal environment. However, evidence of associations between residential greenspace and birth outcomes remains mixed, limiting the relevance this work holds for urban policy and greening interventions. Past research relies predominantly on cross-sectional designs that are vulnerable to residential selection bias, and rarely tests effect modification by maternal race/ethnicity, which may contribute to heterogeneous findings. This study uses a rigorous, longitudinal sibling comparison design and maternal fixed effect analyses to test whether increases in maternal exposure to residential greenspace between pregnancies precede improved birth outcomes among non-Hispanic (NH) white (n = 247,285) and Black (n = 54,995) mothers (mean age = 28 years) who had at least two consecutive live births in California between 2005 and 2015. Results show that increases in residential greenspace correspond with higher birthweight (coef. = 75.49, 95% CI: 23.48, 127.50) among Black, but not white (coef. = -0.51, 95% CI: -22.90, 21.90), infants. Additional analyses suggest that prior evidence of perinatal benefits associated with residential greenspace among white mothers may arise from residential selection; no such bias is observed for Black mothers. Taken together, these findings support urban greening initiatives in historically under-resourced neighborhoods. Efforts to evenly distribute residential greenspace may reduce persistent racial disparities in birth outcomes, an important step towards promoting health equity across the life course.

The change of green space well-being during rapid urbanization: A case study in Jinan, China, 2006-2018.

With the rapid advancement of urbanization, the green space well-being (GSWB) of developing countries faces drastic changes and is increasingly threatened. Green and residential spaces are the core elements of GSWB; however, we know very little about the interaction and combination of the two in terms of their effect on GSWB. This study identified the spatiotemporal features of GSWB and critically examined how patterns of residential-green combinations affect GSWB. Based on land-use data for Jinan from 2006 to 2018, and using the spatial measurement tool GeoDa, we found that both green and residential space have increased significantly in central Jinan. At the macro level, the spatial correlation between the two decreased significantly; meanwhile, at the micro level, there are obvious differences in time and geography. This led to differences in the distribution of GSWB between regions with high value and those with low value. We revealed that the development, preservation, and demolition of residential and green spaces influence changes in GSWB. The positive effects on GSWB come from (1) mountain park development policy in built-up areas, (2) theme park development policy in new urban areas, and (3) urban renewal and demolition policy. The negative effects on GSWB come from (1) issues remaining from prior extensive urban development, (2) the replacement of central areas driven by urban branding, and (3) the lack of supervision of nearby facilities for new housing development. To better understand changes in GSWB, it is necessary to consider its internal residential-green spatial collaboration and propose targeted response strategies. This can help to better safeguard the quality of human settlements in the process of urbanization in developing countries.

Green space in hospital built environment. A literature review about therapeutic gardens in acute care healthcare settings before Covid-19.

Background and aim Hospital facilities are one of the most stressful environments and there is evidence that during Covid-19 having outdoor and green spaces helped medical staff and nurses to decrease the stress and anxiety level. Nevertheless, knowledge about the type of green space is limited. The aim of the study is to systematize the existing scientific literature on the topic in a specific time period.     Methods Scopus, Pubmed, and Cochrane library databases have been explored in a systematic way. Following the Prysma diagram 25 studies have been included. Descriptive statistics and content analysis have been performed to highlight green typologies, users and functional area involved, spatial focus, relationship between users and space and vegetation typology. The different topics have been clustered according to Kellert's biophilic framework.     Results Articles reviewed included studies from the 2000 to 2020. The selection led to the analysis of 25 documents; it was significant to understand the major areas of application (pediatrics, ma-ternity, oncology, hospitalization, etc) and forms of green (images, furniture, healing gardens, vegetable gardens, etc).   Conclusions The present review highlight the main characteristics of green space in hospital built environment with specific focus on pre-pandemic situation.

Collections of small urban parks consistently support higher species richness but not higher phylogenetic or functional diversity.

When prioritizing regions for conservation protection, decisions are often based on the principle that a single large reserve should support more species than several small reserves of the same total area (SLOSS). This principle remains a central paradigm in conservation planning despite conflicting empirical evidence and methodological concerns. In urban areas where small parks tend to dominate and policies to promote biodiversity are becoming increasingly popular, determining the most appropriate prioritization method is critical. Here, we document the role of SLOSS in defining the seasonal diversity of birds in 475 parks in 21 US cities. Collections of small parks were consistently associated with higher species richness, spatial turnover and rarity. Collections of both small and large parks were associated with higher phylogenetic and functional diversity whose patterns varied across seasons and cities. Thus, collections of small parks are a reliable source of species richness driven by higher spatial turnover and rarity, whereas collections of both small and large parks contain the potential to support higher phylogenetic and functional diversity. The presence of strong intra-annual and geographical variation emphasizes the need for regional prioritization strategies, where multiple diversity metrics are examined across parks and seasons.

Cloudy or sunny? Effects of different environmental types of urban green spaces on public physiological and psychological health under two weather conditions.

Numerous studies have demonstrated that urban green spaces (UGSs) benefit human health, but few have focused on the influence of weather on environmental restorativeness. This study assessed how different weather conditions and environments affect human health. We exposed 50 participants to different UGS environments under cloudy and sunny conditions and collected physiological, psychological and aesthetic preference data. The result showed that the physical and mental benefits of UGSs were stronger on sunny days (pulse: [t = 2.169, p < 0.05]; positive affect: [Z = -10.299, p < 0.001]; perceived restortiveness: [Z = -3.224, p < 0.01]). The spaces with exposed sky had greater physiological restorativeness on sunny days; the spaces with calm water had greater emotional restorativeness on cloudy days, and natural spaces with less sky exposure had greater perceived restoration in both weather conditions. The spaces with water and less sky exposure promoted psychophysiological restoration in both weather conditions. This study demonstrates that weather significantly influences the restorative potential of UGSs, and there are also restorative variations in different green space environments under two weather conditions. In future UGS planning practices, it would be advisable to select appropriate environmental types and features based on the climatic characteristics of different regions. For instance, in areas with frequent overcast conditions, incorporating serene water bodies could be advantageous, while regions with predominantly sunny weather should encompass spaces with expansive sky views. By conducting comprehensive research on restoration environments that take weather conditions into account, new insights and nature-based solutions can be provided for creating healthy human habitats in the context of global climate change.

Ecological monitoring of urban thermal field variance index and determining the surface urban heat island effects in Lahore, Pakistan.

Lahore is the second major metropolitan city in Pakistan in terms of urban population and built-up area, making the city a more ideal place to form the surface urban heat island (SUHI) effects. In the last two decades, the considerable land-use conversion from a natural surface (vegetation) and permeable (waterbody) surface into an impervious (built-up area) surface has lead to an increase in land surface temperature (LST) in Lahore. The human thermal comfort (HTC) of the residents is also impacted by the higher LST. The present study uses multi-temporal Landsat (5&8) satellite imageries to examine the ecological and thermal conditions of Lahore between 2000 and 2020. The ecological and thermal conditions of Lahore are assessed by calculating the urban heat islands and UTFVI (urban thermal field variance index), based on LST data which quantitatively assessed the UHI effect and the quality of human life. The outcomes establish that the urban built-up area has increased by 18%, while urban vegetation, vacant land, and waterbody decreased by 13%, 4%, and 0.04%, respectively. In the last 20 years, the mean LST of the study region has risen by about 3.67 °C. The UHI intensity map shows intensification and a rise in surface temperature variation from 4.5 °C (2000) to 5.9 °C (2020). Furthermore, the finding shows that the ecological and thermal conditions are worse in construction sites, transition zones, and urban areas in comparison to nearby rural areas. The lower UTFVI was observed in dense vegetation cover areas while a hot spot of higher UTFVI was predominantly observed in the areas of transition zones and built-up area expansion. Those areas with higher hot spots are more vulnerable to the urban heat island effect. The main conclusions of this study are essential for educating city officials and urban planners in developing a sustainable urban land development plan to reduce urban heat island effects by investing in open green spaces for urban areas of cities.

Quantifying the landscape changes within and outside the Dachigam National Park, Kashmir Himalaya, India using observations and models.

Protected areas are the cornerstone of biodiversity and serve as a haven for biodiversity conservation. However, due to immense anthropic pressures and ongoing changes in climate, the protected reserves are under immense threat. Human interference through land system changes is a major precusor of fragmentation of landscapes resulting in the decline of Himalayan biodiversity. In this context, this research assessed land use land cover changes (LULCCs) and fragmentation within and outside the Dachigam National Park (DNP) using remote sensing data, GIS-based models and ground truth over the past 55 years (1965-2020). Landscape Fragmentation Tool (LFT) helped to compute edge effect, patchiness, perforation and core areas. The Land Change Modeller (LCM) of IDRISI TerrSet was used for simulating the future LULC for the years 2030, 2050, 2700 and 2100. The analysis of LULCCs showed that built-up and aquatic vegetation expanded by 326% and 174%, respectively in the vicinity of the DNP. The area under agriculture, scrub and pasture decreased primarily due to intensified land use activities. Within the DNP, the area under forest cover declined by 7%. A substantial decrease was observed in the core zone both within (39%) and outside (30%) the DNP indicative of fragmentation of natural habitats. LCM analysis projected 10% increase in the built-up extents besides forests, shrublands and pastures. This knowledge generated in this study shall form an important baseline for understanding and characterising the human-wildlife relationship, initiating long-term ecological research (LTER) on naturally vegetated and aquatic ecosystems (primarily Dal Lake) of the region.

Greenspace as Workplace: Benefits, Challenges and Essentialities in the Physical Environment.

There is a scarcity of knowledge regarding the potential benefits of human-nature contact within the context of working life. Even more limited is the research that focuses on working outdoors and the setting in which it takes place. This study aimed to obtain insight into key aspects of the physical environment relevant for the experienced benefits and challenges of workers exploring office work outdoors. We conducted interviews with key informants as well as photo registration and mapping of the different green spaces in the environments of six small or medium-sized workplaces. The information gathered was used as background knowledge for exploratory qualitative interviews, which were conducted while walking in natural settings chosen by the interviewees. With a landscape architectural perspective and an inductive approach, we explored employees' experiences of bringing office work outdoors. The following themes emerged: 'Simplicity,' 'Safeness', 'Comfort', and 'Contact with Nature' were experienced as key aspects in relation to the physical environment, whereas 'Sociality', 'Well-being', and 'Functioning' stood out as the main benefits and, 'Digital dependency' and 'Illegitimacy' as challenges to overcome. Based on the identification of potential benefits and their prerequisites, we propose implications for practice and research that can be useful when focusing on bringing office work outdoors.

Green Spaces as Healthy Places: Correlates of Urban Green Space Use in Singapore.

During the COVID-19 pandemic, when stress levels were heightened and social connections were threatened, a spike in green space visits was observed. Drawing upon the value-belief-norm (VBN) theory, which explains the influence of personal values and world view on perceived obligations to the environment and to action, relevant correlates were examined in relation to people's psychological wellbeing in a bid to better elucidate this phenomenon. We aimed to explore the associations amongst a number of protective factors for psychological wellbeing and to examine the applicability of the VBN theory to wellbeing rather than environmental behaviour. Our research aim was to understand some of the correlates of the use of urban green spaces in Singapore during COVID-19. In total, 268 adult residents of Singapore completed an online survey measuring proximity/frequency of visits to green space, value orientations, nature connectedness, social connectedness, religious belief, spirituality and psychological wellbeing, along with sociodemographic variables such as age and gender. As predicted by the VBN theory, biospheric value orientation and spirituality were positively associated with nature connectedness. The nature connectedness association with psychological wellbeing was completely mediated by spirituality. Frequency of visits to nature was also positively associated with nature connectedness. Neither proximity to nature nor social connectedness were associated with nature connectedness. An altruistic value orientation was associated only with religious belief. Our results indicate that during uncertain times, people are drawing on either social or nature connections as coping mechanisms to fulfil psychological needs and enhance psychological wellbeing. Spirituality mediates this pathway for nature connectedness but not for social connectedness.

Proposing Development of Community-based Physical Activity Park for Elderly Population of Pakistan.

Physical inactivity is known to be as performing less than 150 minutes of moderate- to vigorous-intensity physical activity per week. It poses a substantial risk for not only non-communicable, chronic diseases such as stroke, diabetes etc. but also contributes to the global mortality. Evidence suggests that the usual urban green environment is sturdily related to several health paybacks to the elderly population, which includes not only decreased cardiovascular mortality, Type 2 Diabetes risk, but overall improved physical, emotional, and mental health. It also invokes physical activity for community involvement, natural green curative sensory effect, spiritual boost, and leisure recreation to the elderly. Additionally, parks serve to perform activities like exercise, gardening, brisk walk or simply meditation in the natural environment. Unfortunately, in Pakistan, the urban green spaces like parks are scarce. Most people do not have access to well-designed parks. People over the age of 50 and above seem to be most affected by this deficiency. There is a need for specially designed parks that can address the challenges faced by elderly people while exercising. This study summarises the available evidence for designing special open area space in parks for the elderly population across Pakistan and highlights the need for further work to alleviate the global sickness of physical sedentariness among the elderly. Key Words: Older adults, Parks, Physical activity, Physical inactivity.

Connotation of urban ecological quality and the construction of its core index system.

Urban ecological quality is a necessary attribute for a healthy urban ecological state. In the period of urban development from large-scale incremental construction to stock improvement and quality transformation and incremental structural adjustment, there are many gaps between urban ecological quality construction and the requirements of the new stage. There is an urgent need to understand and integrate multiple needs, and construct an indicator system to promote the balance between supply and demand of ecological resources and efficient use to enhance urban ecological quality. We used the analysis methods of CiteSpace literature analysis, relevant policy collation and questionnaire survey to systematically sort out the key points of concern and differences in understanding among the three perspectives of science, government, and the public. The results showed that all the three perspectives, i.e., science, government, and public, were more concerned with indicators related to urban green space, gray infrastructure, and policy control. The concerns of science and public addressed indicators related to urban green space the most, while government being most concerned with indicators related to gray infrastructure. Based on those findings, we developed a core urban ecological quality index system with a total of 25 indicators, covering 10 major types of urban green space, environmental quality, gray infrastructure, and so on.

Study on the equity of urban green space: Origin, progress, and enlightenment.

Urban green space equity focuses on whether different social groups can equally share the well-being from green space, which is an important issue in the realm of environmental justice. We systematically introduced the origin and development of green space equity, explored its multidimensional progress in conceptual connotation, measurement methodology, phenomenon, mechanism, and regulation, and proposed the enlightenment for deepening the related studies. The green space equity originated from environmental social movement and environmental justice studies, and experienced multilevel evolution in topic constriction and theoretical interpretation. Although the connotation of green space equity was interpreted from various perspectives, its core idea was distributional equality. There was a frequently-used framework for measurement methodology of green space equity, whose spatial scale issue was critical. Due to the differences of characteristics, developmental stages, and institutional backgrounds between Chinese and Western cities, the phenomena and driving mechanisms of green space equity were different. The regulation strategies of green space equity could be summarized into three types, including green distributional equitable strategy, social recognitional justice strategy, and procedural justice orientated strategy. Future studies should deepen the research from the hierarchical logics for practice management, the fine-scale measurement methodology, the interpretation of mechanism for green space inequity in Chinese context, and simulation of differentiated regulation strategies. Social development endows green space equity with more practical tasks and theoretical logics, which is urgent to clarify the research progress to support the future research.

Perceptions of the health risk from hot days and the cooling effect of urban green spaces: a case study in Xi'an, China.

Background: Hot days are one of the typical threats to human health and sustainable cities. The exploration of residents' perceptions of thermal environment and its mitigation measures will support the health risk prevention. Methods: A survey with a combination of closed-ended and open-ended questions was conducted in July 2021 among 13 urban parks in Xi'an City, China. With the help of ANOVA and ordinal logistic regression, this study investigated the influencing factors both on residents' health risk perception of hot days and their perception of the effect of urban ecological landscape on reducing the thermal risk. The relationship between health risk perception and residents' needs of urban ecological construction was also explored. Results: According to 325 valid questionnaires, the male-female ratio of respondents was found to be 1:0.87, young people aged 18-29 (26.46%), the retirees (27.08%) and the ones with undergraduate education (33.23%) were, relatively, the largest groups. The results show that 92.31% of the respondents believed that their daily lives were under the influence of hot days. Housing types, occupation, cooling equipment at work, and outdoor working hours all had a significant impact on their high temperature perceptions. The proportion of respondents who were under a huge health risk and sought medical treatment due to hot days was 30.16% and 44.92%, respectively. Women were 18.52 and 2.33 times more likely to suffer health threats and experience discomforts than men. Furthermore, 73.23% of the respondents believed that the urban ecological landscapes in Xi'an had an enhanced cooling effect in recent years. Compared with the morphological characteristics, residents' recognition of the restriction of landscape's area on its cooling effect was higher, and the residence duration showed a significant influence. Conclusion: The cooling effect of green spaces and water effectively resisted urban thermal threats, and residents' needs of the urban ecological landscapes was associated with their health risk perceptions of hot days. In the future, it is necessary to promote the early warning of hot days, meanwhile, the optimization of landscape patterns of green infrastructures should be implemented in urban planning for the purposes of residents' health risk prevention.

Construction and planning application of blue-green ecological network in Ruzhou City based on morphological spatial pattern analysis (MSPA).

Land space planning is an important way to realize the construction of ecological civilization. It is important to improve the ecological service capacity of urban blue-green space during land space planning and combine it with planning strategies. With Ruzhou City from Henan Province as the research area, we constructed the current blue-green ecological network by morphological spatial pattern analysis (MSPA), connectivity analysis and minimum cumulative resistance model, and explored the application of corridor construction in land spatial planning. The results showed that there were seven first-level core patches, which were mainly distributed in the mountain forest space in the southwest and northeast of the city and the belt ecological space formed by Ruhe River in the middle. There were nine second-level core patches. A total of 256 ecological corridors and 135 ecological nodes were screened out. Most of the corridors crossed Ruhe River, so we should focus on protecting Ruhe River and its surrounding environment, providing temporary habitat for biological migration from north to south, improving the stability of overall ecological network, and concerning the restoration of the corridor breakpoints on the west and south sides of the city. It could guide the division of urban development boundaries, and provide scientific basis for the functional orientation and classified management and control of corridors from the perspective of planning.

What is known about what works in community-involved decision-making relating to urban green and blue spaces? A realist review protocol.

BACKGROUND: There is now a relatively well-established evidence base suggesting that greener living environments and time spent in urban green and blue spaces (UGBS) can be beneficial for human health and wellbeing. However, benefits are not universal and there remain widespread social inequalities in access to such resources and experiences, particularly along axes of class, race, ethnicity, age and disability, and in relation to efforts to increase the availability and accessibility of such spaces. These injustices often relate to distributive, procedural and recognition-based processes. There is growing interest in how to ensure that efforts to increase access to or use of UGBS (whether through infrastructural or social programmes) result in equitable outcomes whilst minimising potential for exacerbating existing inequalities and injustices. Community engagement is considered an important step towards more inclusive UGBS decision-making, from planning and design to management and maintenance processes. It is thought to contribute to better and more widely trusted decisions, enhanced democracy, community satisfaction, civic interest and feelings of green space ownership, and greater longevity of UGBS projects. However, uneven representation and barriers to participation can create imbalances and undermine these benefits. METHODS: An iterative, multi-stage realist-inspired review will be conducted to ask what works, in what context and in what ways relating to the meaningful involvement of communities in UGBS decision-making, focusing on the skills, capacities and capabilities of different stakeholders and the role of contexts and processes. 'Effectiveness' (or what works) will be understood as a multifaceted outcome, encompassing both the processes and results of community engagement efforts. Following a scoping stage to identify initial programme theory, inclusion/exclusion criteria and derive search terms, relevant databases and grey literature will be searched to identify interdisciplinary literature in two phases. The first phase will be used to further develop programme theories, which will be articulated as 'if then' statements. The second phase searches will be used to identify sources to further explore and evidence the programme and formal theory. We will assess all includable evidence for conceptual richness, prioritising more conceptually rich sources if needed. DISCUSSION: The realist synthesis will explore the key context, mechanism and outcome configurations that appear to explain if and how different approaches to community-involved UGBS decision-making are or are not effective. We will consider factors such as different conceptualisations of community, and if and how they have been involved in UGBS decision-making; the types of tools and approaches used; and the socio-cultural and political or governance structures within which decision-making takes place.

Support for management actions to protect night sky quality: Insights from visitors to state and national park units in the U.S.

Light pollution is a global phenomenon where anthropogenic light sources continue to grow unabated, affecting both social and ecological systems. This is leaving parks and protected areas as some of the last vestiges of naturally dark environments for protecting views of the night sky. Yet, even parks and protected areas have outdoor lighting. Alternative lighting practices are needed to reduce or prevent light pollution from within parks. However, making parks darker may not be desirable for some visitors if they believe it will reduce navigability, safety, or restrict how they recreate (e.g., requiring the use of red-light flashlights after dark and before dawn). How visitors will respond to alternative lighting practices that park managers can implement is still unknown. We used an on-site intercept survey at nine state and national park units in Utah, U.S., to investigate nighttime visitors' support or opposition to management actions to protect night sky quality and their interest in learning about topics related to night skies. Further, this study also segmented visitors into two groups: those 'dependent' on the dark sky as a resource and those whose activities did not depend on a dark sky. Defining what a 'dark sky dependent' visitor is, which has yet to be done in the literature, is a fundamental step to furthering night sky research and management efforts. Across nine parks and protected areas, 62% of nighttime visitors participated in dark sky dependent activities. Findings indicate broad support for management actions designed to improve night sky quality, with between 74% and 89% of all visitors supporting seven different management actions. There was stronger support from dark sky dependent visitors for some elements of alternative lighting practices, but there was still strong support for those who do not participate in dark sky dependent outdoor recreation. Additionally, between 57% and 75% of visitors were interested in learning more about topics related to night skies. This research indicates most visitors would welcome actions to preserve the quality of the rapidly dwindling naturally dark experiences offered by parks and protected areas.

How to transform urban institutional green spaces into Ancillary Botanic Gardens to expand informal botanical learning opportunities in cities.

Since many cities lack botanical gardens, we introduced the concept of Ancillary Botanic Gardens (ABG), which builds on the premise that organizations can expand informal botanical learning by adding a secondary function to their institutional green spaces. This study guides the application of the ABG concept in various spatial and functional contexts by offering practical and interpretive tools to organizations who are less used to working with nature but are interested in mitigating urban residents' detachment from nature. Online maps of 220 botanic gardens were reviewed to define types of plant collections and produce an exhaustive list of physical botanic garden elements. The collected information was developed into an ABG field checklist that was tested on three case studies in Lebanon and then used to develop guidelines for ABG establishment. The guidelines and checklist are meant to empower and guide organizations interested in establishing an ABG.
