What has happened to the mangroves in Tai O?

Climate change has intensified pest problems.

Global warming increases the likelihood of pest outbreaks. Hotter weather makes insects more active.

In 2023, the ‘White Bone Soil’ mangroves in Tai O were attacked by insects, with the trees showing signs of wilting. A large number of leaves were consumed by green caterpillars, which are believed to be moth larvae.

In 2012, the Avicennia marina at Mai Po also suffered from extensive damage due to moth larvae, resulting in widespread wilting.

Caterpillars covered the leaves.

A large number of mangrove leaves were consumed.

Global Mangrove Overview

According to reports from Wetlands International and global studies, since 1980, mangrove ecosystems have been severely impacted by development in mangrove areas, industrial pollution, agricultural runoff, and global climate change. Due to factors such as water pollution, climate change, rising sea levels, and excessive commercial fishing activities, the global area of mangroves has decreased by approximately 50%.

The situation of the mangroves in Tai O

A wetland area in Tai O, originally a derelict salt pan, was restored between 2005 and 2007. This restoration project was undertaken to compensate for the loss of mangroves due to the construction of the Hong Kong International Airport at Chek Lap Kok and the development of North Lantau. Various native mangrove species were replanted during this period.
This expanse of mangroves nurtures a diverse array of wetland animals, including crabs, mollusks, mudskippers, and water birds. Approximately fifty species of mangrove-dependent animals have been recorded in this area.

Value of Mangroves

Natural Barrier

Protecting Coastal Areas from Natural Disasters

Establishing Unique Coastal Ecosystems

Coastal ecosystems such as mangroves, salt marshes, and seagrass beds offer crucial habitats for a diverse range of marine and coastal species.

Improving Water Quality

Root Systems and Tree Trunks for Water Quality Improvement

Mitigating Global Climate Change

Carbon sequestration capabilities, which absorb and store large amounts of carbon, help mitigate global climate change.

Students and Elderly Residents Work Together at Designated Locations to Transplant Mangrove Seedlings
Students Regularly Visit the Designated Locations to Monitor Mangrove Growth and Report Their Findings to the Elderly Residents

Program Objectives

intergenerational harmony

By facilitating interactions between young people and the elderly, we can promote communication between the two generations. This allows elders to pass on traditional knowledge and accumulated social experiences to the younger generation, while young people bring fresh perspectives and new information to the elderly. This, in turn, deepens mutual understanding and recognition between the generations, helping to build a harmonious, inclusive, respectful, and integrated society.

leads students to Elderly Care Homes to Share Mangrove Planting Experiences

Provide students and the elderly with the opportunity to understand the ecological value and importance of mangroves, helping them grasp the concept of sustainable development. This fosters their awareness and concern for the natural environment, enabling both generations to work together in contributing to environmental conservation.

Community care

The plan is to have students engage with elderly residents in care homes, promoting intergenerational communication, enhancing community cohesion, and fostering a spirit of care and compassion.

Sustainable Development Goals

Event Highlights

On the day of the event, director Lu at Tin Ching Nursing Home provided strong support. Relevant experts taught the elderly how to plant mangrove seedlings, which were then placed within the nursing home for cultivation. At the appropriate time, these seedlings will be transplanted to the mangrove forest in Tai O.

After Dr. Cheng’s introduction and planting session, the elderly participants tried their hand at caring for the mangrove seedlings, adding enjoyment to their lives!
