Introduction
Ourselves Abinaya .G , Divya kamatchi .S , and Haridharani .J.B from Masters of landscape Architecture 2nd year students from Dr.M.G.R Educational and research institute , Chennai . All of us are from different cities and different colleges in our Undergraduation that is Bachelor of Architecture course.
As a student of landscape architecture we know the importance of a forest . Especially in the urban areas. Our college location is near by the banks of the cooum river in a busy urban area. We witness the condition of the river banks in our regular basis which can be utilized for both ecological and social wellbeing . So we came across this Archiol Tiny forest competition 2023, we wanted to use this opportunity to treat the river banks with dense forest.
Design Concept
The idea was to treat the banks of river cooum. Knowing the historical value of the cooum river we wanted to rejuvenate the cooum river and enhance the Ecological value . We created Tropical evergreen forest which helps to increase the carbon sequestration level as well as pollution level of water . Selection of Plant and Tree species was our first priority . Using the non destructive method of Computation of carbon storage we selected native tropical evergreen species of Chennai city which could survive on river banks . In designing we categorised the site into three zone namely Zone A – Undisturbed Zone , Zone B - Managed zone , Zone C - Active recreation zone . The Tiny forest canopy layers of the selected species were enhanced in the design like Canopy layer , Sub Canopy layer , Under storey layer , shrub layer and forest floor .
We created a balanced amphibian ecosystem developed along the Aquatic and terrestrial area. The main goal was to cleanse the environment through proposing plant species with higher carbon sequestration level as well as higher survival rates in the river banks . This will provide significant oxygen supply and shelter for animals and birds . It will prevent the soil erosion and uphold the fertility of the soil also enhances the local bio diversity.
As we mentioned before , our college is located near the cooum river bank. Cooum Once known as ‘Thames of South India’, the highly polluted and toxic Cooum river flows through several areas of the Chennai city. The narrow, slow and meandering 65 km long Cooum river, once a freshwater source, originates in a village of the same name in neighbouring Tiruvalluvar district and ends in the city. It almost bisects the city. At present the river faces a number of problems like excessive use of water for irrigation upstream, inadequate sewage collection, industrial pollution, encroachments along the banks and closure of the river mouth due to littoral drift.
Challenges : We selected trees and plants species native to Chennai cityany . In past , when Chennai faced many disaster like Vardha cyclone . Mandous cyclone , Gaja cyclone etc. Many native trees survives all these disaster when compared to invasive species .
Ecological Relevance
The design focuses on increasing the ecological value by increasing the bio diversity value of the space. Natural food chain will be maintained. Selection of species was highly prioritized for planning a tiny forest. Native species which has a higher carbon sequestration value was selected.
Tiny forests are designed to be highly biodiverse, with a wide variety of native tree and shrub species planted in close proximity. This creates a rich habitat for a wide range of wildlife, including birds, insects, mammals, and amphibians. Tiny forests absorb carbon dioxide from the atmosphere, which helps to mitigate climate change. They also provide shade, which can help to cool urban areas and reduce the energy demand for air conditioning.
Tiny forests provide a number of other benefits to the planet, including: Reducing air pollution ,Improving water quality , Preventing soil erosion ,Providing recreational and educational opportunities for people
Sustainable Integration
Native plants are adapted to the local climate and soil conditions, and they are more likely to survive and thrive. They also provide food and habitat for native wildlife. Plant a variety of tree and shrub species will create a more diverse and resilient forest. Organic mulch helps to retain moisture and suppress weeds. It also breaks down over time to improve the soil. Water conservation is important, especially in areas with limited water resources. Tiny forests can provide a variety of benefits to people, such as improved air quality, reduced stress levels, and opportunities for recreation and education.

We get to know about this competition from our college as they have given it as an academic design project. Our sincere thanks to our university for showing such an opportunity and special thanks to our professors for their support and guidance.
This is our pleasure to work under this topic and I think this is such a important thing to be discussed in various platform and raise up the importance of ecological balance and the cycle and the circulations has to get notified and get followed to maintain healthy ecosystem.
Design Concept
This site was selected as it already has a proposal for tiny forest. A diverse mix of native plant species is carefully selected to replicate the layering found in natural forests, including canopy, understory, shrub, and ground cover layers. Native species are chosen to support local wildlife, pollinators, and beneficial insects while requiring minimal maintenance.
The chosen plant species are not only aesthetically pleasing but also provide food, shelter, and nesting sites for birds, insects, and other wildlife. The diversity of plant species encourages a range of animals to inhabit the area, contributing to the overall ecosystem health. Miyawaki method has been used as it is one of the most effective tree planting methods for creating forest cover quickly on degraded land. Native trees such as Neem, Pongamia, Bamboo, Arjun, Banyan, and Peepal will help achieve the above goals.
It provides a habitat for various plant and animal species, helping conserve biodiversity. They absorb carbon dioxide, acting as carbon sinks, which helps mitigate climate change. It improves local air quality by filtering pollutants and can assist with water purification by reducing runoff and erosion.
A well-designed tiny forest contributes to maintaining ecological balance on our planet Earth. Tiny forests provide a habitat for various plant and animal species, helping conserve biodiversity even in urban areas.
Selecting the right mix of native plants and trees that will thrive and support local biodiversity is crucial but can be complex. Limited space in urban environments can be a challenge, requiring innovative design to maximize the benefits of a small area.
Ecological Relevance
If we have to live in an environment means it has to get balanced to build a strong ecosystem, it is a stable cycle that has to continue to maintain a balancing environment and living. They offer valuable ecosystem services, such as providing food and habitat for pollinators, supporting soil health, and offering recreational opportunities.
Biodiversity : Species were selected based on a diverse selection of plant species that provides food and habitat for various insects, birds, small mammals and reptiles.
Climate change : Selected trees can absorb carbon dioxide during photosynthesis, helping to reduce greenhouse gas levels in the atmosphere will helps in mitigating climate change.
Overall health : Air purifying plants also selected which will filter pollutants from the air, leading to cleaner and healthier urban environments.
Sustainable Integration
Sustainable design principles such as native plant selection that are adapted to the local environment, as they typically require less water and maintenance. Promoting biodiversity by including a variety of plant species and creating habitats for local wildlife.
Lake near to the site is a prominent element and bringing the lake water to the forest offers several ecological, aesthetic and recreational benefits using bioremediation. Creating specific habitats like birdhouses, bat boxes, or insect hotels to promote biodiversity within the tiny forest.
Design Development
We classified tiny forest into various zones - Aquatic zone, Riparian zone, Lowland forest, Woodland forest, Upland forest, Grassland.
Creating a lake in a forest can offer numerous ecological, aesthetic and recreational benefits. Bioremediation, it is the process of using living organisms, such as plants, bacteria, and fungi to clean up and restore contaminated environments, including lakes in forests.
Miyawaki method has been used, accelerates forest development by constructing soil, utilising native plant diversity, growing healthy saplings, and planting them close together. In this method multi-layered saplings are planted close to each other. This blocks sunlight from reaching the ground and prevents weeds from growing, thus keeping the soil moist. The close cropping further ensures that the plants receive sunlight only from the top thus enabling them only to grow upwards than sideways. Growing the saplings close also ensures space for more trees to be planted.
Community Impact
Biodiversity Enhancement: A tiny forest can serve as a biodiversity hotspot, providing habitat and food sources for local wildlife. This can enhance the local ecosystem and educate the community about the importance of preserving biodiversity.
Community Green Space: Tiny forests can become valuable green spaces for communities, offering a place for recreation, relaxation, and social interaction. These spaces can improve mental well-being and quality of life for residents.
