About PEP

Woodlands were largely destroyed in World War II. The Hong Kong government has invested a lot of resources in massive afforestation work to restore barren hillsides and eroded slopes. Most areas were seriously eroded and due to the relatively higher adaptability of exotic tree species, they were strategically chosen to plant as pioneer trees to help land rehabilitation and soil erosion control. Before the 80s, exotic tree species such as Acacia confusa, Lophostemon confertus, Pinus elliottii were widely planted in local afforestation projects.

 

Though exotic tree species have had good performance in controlling soil erosion in the past, these woodlands are now facing with many problems such as aging, lack of growing space, low habitat diversity and species biodiversity, etc. Some of these exotic tree communities are even exclusive in nature. It is difficult for other tree species to grow underneath by natural succession, making rather slow natural regeneration of native plants.

 

In order to enhance the ecological values of these plantations, the Agriculture, Fisheries and Conservation Department (AFCD) launched a programme named “Country Parks Plantation Enrichment Project (PEP)” in 2009. Major measures include thinning of aging exotic tree species (such as Acacia confusa, Melaleuca cajuputi and Eucalyptus, etc) planting of native tree seedlings and post-planting maintenance. The Green Earth has started participating in the project from Dec 2016 and gathering public efforts to build native tree woodland together. Through planting native tree seedlings in the existing woodlands, the project aims to increase biodiversity and ecological values of plantations in country parks.

Site 6

Vegetation was ruined by hillfire in 1999. Restoration plantation was carried out in 2000 to 2001. 20,000 seedlings were planted, in which around 35% were local species. After 17 years, Acacia confusa and Casuarina equisetifolia are now the dominant species in the woodland.

Site 7

It is located next to South East New Territory landfill. The government has established the woodland with mainly Acacia confusa as a natural barrier. Another public plantation project was carried out in 2004. 10,000 seedlings were planted in which 60% were local species. As constantly affected by sea breeze, exotic trees performed better than native species. Acacia confusa has therefore become the dominant species.

How to convert the woodlands?

1. Divide the woodland into many study quadrats

2. Strategically remove exotic tree species within the designated quadrats

3. Replace with native tree species

4. Annual growth check and tree-care maintenance (like weeding and adding fertilizer)

5. Conduct ecological survey regularly

 

The process will take at least 5 years.

 

Different from normal tree-planting activity, all PEP procedures are conducted in existing woodlands. It will be a new experience to most members of the public.
