Basic information on mangroves in Tan Tau Village
According to the Study Report on the Biodiversity of Natural Mangroves in Tantou, Nansha, Guangzhou, according to studies such as marine geology and sporopollenology, there were historically large and dense mangroves distributed in the Nansha District, but due to long-term sea enclosures, polder farming, and urbanization, the natural mangroves have been almost destroyed. A study by Li Mei (2009) on the diversity of wetlands in Nansha, Guangzhou, found that only 63 h? of mangroves were found in Nansha District, and most of them were planted forests. At present, the surviving patches of natural mangroves in Tantou Village are rare in Guangzhou.
The mangroves in Tantou Village are mainly distributed in Caochuan Village, and the existing natural mangroves cover an area of 30000?, accounting for more than 70% of the existing natural mangroves in Guangzhou, and two old trees of Kandelia obovate, which are more than 100 years old, have been found. So the mangroves in Tantou Village have important conservation and scientific research value.
Policy Context
During the "14th Five-Year Plan" period, the Guangzhou Municipal Government attaches great importance to the construction of marine ecological civilization and the protection of mangroves resources, expecting to accelerate the pace of construction of marine ecological civilization in Guangzhou by increasing the comprehensive improvement of the ecological environment of the near-shore sea area in Nansha District and the effective management of the marine ecological environment. By 2025, Guangdong will create 5,500 hectares of mangroves and restore 2,500 hectares of existing mangroves, and the "Guangdong Province Mangroves Protection and Restoration Special Action Plan Implementation Plan" arranges for Guangzhou Nansha District to create 43 hectares of mangroves and restore 160 hectares of mangroves.
As Tantou Village already has patches of natural mangroves, it has not been included in the scope of the creation and restoration in recent years, but the mangrove restoration and protection activities in the area are of great significance and are currently managed by the local street office.
The Blue Carbon Initiative
In 2021, the Association participated in the mangroves status survey and assessment project in Nansha District, Guangzhou, and has a deep understanding of the status of mangroves in Nansha District.

? Main problems and needs
Main problems
(1) The natural mangrove species are relatively homogeneous, making it difficult to give full play to their ecological functions.
(2) Some plants (Mikania micrantha, fish vine, Sonneratia apetala Buchanan-Hamilton) encroach on the living space of mangroves, which easily makes other plants stop growing or even die, affecting the diversity of this ecosystem.
(3) The surrounding residents have insufficient ecological significance and awareness of mangroves, weak protection consciousness, and the survival environment of mangroves is still threatened in their daily life activities.
(4) The public generally has insufficient knowledge of mangroves, limited knowledge of the ecological functions and environmental benefits of mangroves, unclear responsibilities for their related protection, confused management, lack of scientific development and management planning for the existing mangroves, and even more so for the mangroves polder and indiscriminate occupation causing artificial destruction, so that the mangroves ecosystem is threatened.
Needs
(1) Scientific replanting of some mangrove trees according to the growth of mangroves in this area to enrich mangrove species and improve ecological benefits.
(2) Continuously clean up invasive tree species/those that pose a threat to the growth of other tree species to effectively improve the diversity of this ecosystem.
(3) To establish a voluntary protection group for the natural mangroves in Tantou Village with the residents of the community and public welfare organizations so that the natural mangroves in the area can be effectively protected in the long term.
(4) Relying on the voluntary protection group, we will enhance the awareness and protection of mangroves among the surrounding residents and the public through online and offline mangroves ecosystem science, protection awareness training, and nature education activities.

? Proposed activities to achieve the objectives
Activity 1
Mangroves replanting
1. Collaborate closely to establish an expert mangrove replanting team and form a team of trained and qualified volunteers.
2. Confirm the planting area, prepare mangroves seedlings and related planting tools, confirm the planting time according to the weather conditions and confirm with advance notice.
3. Carry out mangrove replanting activities in the field.
4. Follow-up monitoring and maintenance of replanted mangrove trees by professionally trained personnel.
Activity 2
Mangroves protection volunteer group building
1. Design a planning plan for the running mechanism of the volunteer group.
2. Communicate the plan with the local street office and, get support, issue the corresponding certificate.
3. Recruit corresponding volunteers in the local community, mainly for: parent-child families, retired elderly (under 70 years old), and primary and secondary school students.
4. Recruit corresponding volunteers in Guangzhou city to join. The main recruitment targets are parent-child families, college students, and mangrove experts.
Activity 3
Based on the series of activities of the Mangroves Protection Volunteer Group
1. Mangroves ecosystem science popularization micro-lesson development, mother volunteer instructor training.
2.Mangroves ecosystem knowledge popularization activities: online knowledge contest on 7.26 International Day of Mangroves Ecosystem Protection.
3. Mangrove growth environment litter cleanup activities: June 5 World Environment Day / June 8 World Oceans Day.
4. Practical activities of mangrove nature education.
5.Special exhibition of mangrove science.
Activity 4.
Assessment of natural mangroves carbon stocks in Tan Tau Village
1. Carry out relevant research and assessment work.
2. Form the corresponding report materials.
Activity 5. End of the year, summing up the commendation meeting

Conference preparation.
Summarize the work carried out in this project cycle.
Recognition of contributing groups and individuals.


? Anticipated results
The replanting of about 300 mangrove trees of 100cm will improve, to some extent, its uneven distribution and simple community structure in order to protect the coastal zone and marine ecosystem. In addition, the public's practical participation in the replanting of mangroves plays an important role in raising their conservation awareness and practical ability, and in this way, forms a driving and demonstration effect to boost the conservation awareness of mangrove ecosystems.

Obtain support from the street office and local civil affairs system to form a stable mangroves protection volunteer group with a core staff of 50 and a total number of volunteers of 300 or less, which will operate stably during the project cycle.

Through a series of mangroves-themed activities to raise public awareness of mangroves awareness and protection, it is expected to reach more than 50,000 people.

Investigate the carbon stock situation of natural mangroves and form a report.
The research association will take the lead and invite government management, experts and scholars, participants, and representatives of local residents to participate in the conference to summarize the relevant work and commend the contributing groups and individuals in order to promote the spirit of volunteer dedication.
