Guangzhou University Stormwater Management Guidence Handbook
With the expansion of urban land in Guangzhou, forest land is becoming less and less. Human habitats are expanding, while wildlife habitats are decreasing. Many native species have disappeared. In 2010, the Guangzhou Municipal Government tried to introduce extinct native animals. The red-bellied squirrel briefly appeared in the city, but with little success. This design establishes a "patch-matrix-corridor" system. Therefore, the green patches in the main urban area of Guangzhou can be connected, and wild animals can freely travel and live in the city. 02
Urban Rewilding: Saving Red-bellied Squirrels
The design explains that under the combined effects of weather changes and urban development, urban flooding in Guangzhou will become more and more serious. As a region where walking is the main mode of transportation, Guangzhou University faces more urgent flooding problems. This design hopes to improve the rainwater management system of universities in Guangzhou, propose solutions for each module, and create a standardized flood response manual.
Reconnecting the Riverside Industrial Rust Belt
As the last remaining power plant in Guangdong Province, Guangzhou Xicun Power Plant is also the earliest power plant built in Guangdong Province, and has a high value of protection. This design aims to revitalize the public space of the power plant, connect it with the surrounding industrial rust belt, and set up a waterfront slow-moving system, so that the old power plant can continue to generate electricity for the community today.
Memory of Seeds: From the World to Paris
The Paris Botanical Garden in France has been collecting plants from all over the world since the 17th century and storing them in the garden. These seeds have come to this land through deserts, rainforests, and oceans, and have taken root and sprouted here. This design aims to commemorate the long history of storing and collecting plants in the French Botanical Garden.

In the next 30 years, under the normal development scenario, the hazard (HR) and vulnerability (VLR) of urban waterlogging will increase sharply.
Under different scenarios, urban development has a greater impact on urban waterlogging than climate change. Urban development has a significant impact on urban waterlogging risk because rapid urban development can lead to drastic changes in land use and landscape surface characteristics. Urban development has a greater impact on waterlogging

Loss Of Wildlife Habitat Due To Urban Expansion Location
Urbanization: Habitat Loss and Biodiversity Decline
The land-use changes in an urban fabric tends to fragment forested and other types of habitat, and to convert extensive areas into isolated islands within predominant urban environments. The concern is that these remnant environments are often islands, disconnected from the rural landscape and from each other by the expanding city. And so, where they remain isolated and small, the chances ofmaintaining high wildlife diversity, particularly animals, are relatively small.
Urbanization not only causes us to lose our habitat…

Phase 2: Excessive Urbanization
I'm back ! I can live in the White Mountains and some parks now, although there's very little I can do in the city ...... I'm a native of Guangzhou. Many years ago, I would often appear on the city streets. There are fewer and fewer large green spaces in the city. We have to move to the northern forest.
Phase 1: Balanced Development
Before 1990,
and
Around 2000, Guangzhou experienced a huge urban expansion. The economy and technology of Guangzhou developed rapidly, but at the same time, forests and other green areas were also encroached upon, and wild animals gradually disappeared in the urban area.
Phase 3: Wildlife Into the City Program
In 2011, Guangzhou officially launched the "Wild Animals into the City" plan and established six demonstration sites. The introduced wild animals include squirrels, hares, pheasants, red-collared green parrots, red-headed pochards, spot-billed ducks, herons, egrets, night herons, etc.
Poor Forest Quality
Most of the existing forests are artificial forests, with few natural secondary forests. The forests have a single tree species and poor quality.
Low Planting Diverse
Most of the green spaces in cities are artificially planted in regular patterns, lacking diversity and randomness, which leads to a reduction in biodiversity.
Due to the continuous expansion of the city, the green space in the city has been fragmented, forming small isolated islands with no connection. Fragmented
Future: Symbiosis
By moderately rewilding the over-urbanized city, Guangzhou will become a wilderness urban garden where humans and animals coexist, allowing wild animals to survive and reproduce in the city just like humans.
Guangzhou had less urban land,
the living space for wild animals and humans could be kept in a balanced state.
Squirrels like to live on plants belonging to Fagaceae, Taxaceae, Pinaceae, but most of the Fagaceae plants in Guangdong are endangered.

Habitat for Red-bellied Tree Squirrel
or down slopes when threatened, thus avoiding predation by predators.
Red-bellied squirrels like to live in mixed needleleaved and broad-leaved forests and evergreen broadleaved forests.
Squirrels generally feed on fruits, flowers and leaves. When building nests or in seasons when food is scarce, they will gnaw on tree bark to survive.

“Matrix"- Forest Area
Step 1: Stochastic Thinning
A large part of the original forest is artificial forest, with dense and single tree species, which is not conducive to the development of diverse habitats. Randomly cut down or burn some old or dead trees. The tree density needs to be reduced to 1,000-1,200 trees per hectare.
Step 2: Land Cover Remediation
Soil is an important component of forest ecosystems, and its quality and health directly affect the stability of the ecosystem. Improving soil can effectively promote the recovery and stability of the ecosystem. The application of soil improvement measures in forest ecosystem restoration includes soil and shrub improvement.
Step 3: Complex Community Construction
With sufficient free space and a good soil foundation, the forest is replanted with multiple species and at multiple levels, making it a diverse and complex ecosystem. The diversity of plant species is the basis of animal species diversity. Forests are the main habitat of red-bellied squirrels.
The trees will randomly reduced by two method: artificial felling and simulated wildfires. And the felled wood will not be hauled away but will remain on site as organic mulch.
Soil covering is a simple and effective method of soil improvement. By covering the soil surface and adding the biochar, it can effectively maintain soil moisture and nutrients, improve the ecological environmental suitability of the soil.
Biodiversity is very important in natural habitats. The diversity of habitats is achieved through two methods: multi-level and multispecies replanting. Trees of different ages, levels and species will greatly increase habitat diversity.
Step 1: Micro-Topography Design
Topographic change is the main causality to spatial heterogeneity. The macroscale terrain design would help regulate the evolution and distribution. Enriching the topographic relief helps create diverse niches, providing suitable growth conditions for various plant communities.
Steep slope
“Patch"- City Park
Step 2: Quasi-Nature Design
The ‘blank - planting’ mosaic complex should be established, which is not only conducive to community self-design, but also limits the growing space of migratory species and promotes the formation of clusters of autochthonous plants.
Plant space: assembly of needle-leaf tree species
Step 3: Self-Design
In urban parks, most landscape waste, such as fallen leaves, dead wood, and piles of rubble, will be removed regularly, but they are good shelters for wild animals. In corners of parks where human activity is low, try to minimize disturbance to the environment and keep the landscape waste to allow the self-design.
Of
food supplement Assembly Of Needle-
Artificially (low intervention) or naturally (animal self-design) discarded branches and stumps are combined into animal nests to prevent animals from gnawing on the bark to build nests. Leaving landscape debris (dead leaves, rock piles, bushes) in place creates a natural shelter for wildlife to avoid predators and navigate the park.
Nature Rivers
Rivers are important corridors in cities. Breaking down artificial rivers and returning them to nature can not only increase the beauty of the city, but also increase the richness of species.
“Corridor"- Urban Space
Nature Ways Nature Highways
Most of the city's streets are heavily artificial and lack plant layers. Multi-layered, multi-species streets can increase species richness and provide these creatures with shelter, nesting, feeding, and migration possibilities.
The elevated space in the city is often overlooked. The space under the elevated road is relatively far away from the interference of people and is an important passage space in the city.
Abandoned industrial sites separate the riverside roads
Most of Guangzhou’s industrial heritage sites are located on both sides of the Pearl River. Due to the large amount of activity space and beautiful riverside waterscape, most of the industrial heritage sites with far-reaching influence and commemorative value have been revitalized into public leisure spaces and connected into belts.

Through the Rainforest
In 1800, the Parisian Jardin des Plantes began collecting rainforest plants, sparking curiosity about the lush, vibrant world hidden beneath the canopy of dense tropical forests. Imagine a rainforest scene teeming with life and color, with the sky often obscured by intertwining foliage, and only a ray of sunlight able to penetrate, creating dazzling beams of light on the forest floor. Biodiversity is at its peak here, with towering trees home to countless species and ferns unfurling their delicate leaves. With its intricate web of life and indomitable vitality, the rainforest captivated botanists at the famous Parisian gardens two centuries ago, inspiring people to understand and protect the wonders of this amazing ecosystem.
Across the Desert
In 1799, the Parisian Jardin des Plantes began collecting desert plants, sparking interest in the arid landscapes these exotic species thrive in. Imagine a vast, unforgiving desert, where the sun relentlessly bakes the dunes, staining them in shimmering shades of gold and amber. The air is dry, with the faint scent of distant sagebrush and the earthy smell of arid soil. Here, life persists, with cacti and succulents displaying their remarkable adaptability—thick fleshy leaves that store precious water, spines that deter thirsty predators, and bright flowers that bloom during the brief rainy season. The horizon stretches endlessly, punctuated by the occasional solitary silhouette of a Joshua tree or the rugged contours of a rocky outcrop. In this harsh yet fascinating environment, every plant and creature tells a story of resilience and survival.
Over the Ocean
In 1767, the Paris Botanical Garden began collecting Oceania plants, and the luxuriance of various plants in the rugged and beautiful island and coastal landscapes is fascinating. Oceania has landscapes of mangrove swamps, rainforests, sclerophyllous forests, showcasing the plant diversity of archipelagic habitats. The horizon is dotted with the outlines of distant islands, and the lush greenery contrasts with the blue of the ocean. For hundreds of years, the botanical research of the Paris Botanical Garden has not only celebrated the terrestrial wonders of Oceania, but also hinted at the wider charm of its marine environment, where life flourishes in a symphony of beauty and interdependence.
