Ecological Evaluation of Abandoned Agricultural Land
Criteria Abandoned Agricultural Land
 

Naturalness

Man-made habitat abandoned for natural succession.

Size

One of the main habitat types in the Study Area within the Hong Kong boundary, with an overall size of approximately 82.5 ha.

Diversity

Moderate floral and low to moderate faunal diversity.

Rarity

No plant species of conservation interest. Bird species of conservation interest included Common Buzzard (Buteo buteo) flying above; Savanna Nightjar (Caprimulgus affinis) calling; Greater Coucal (Centropus sinensis) perching; Lesser Coucal (Centropus bengalensis) perching; Chinese Pond Heron (Ardeola bacchus) foraging; White-breasted Waterhen (Amaurornis phoenicurus) perching.

Re-creatability

Habitat characteristics and species composition are easy to re-create and may take 1 to 2 years to mature.

Fragmentation

Interspersed with cultivated land but mainly linked. Low fragmentation

Ecological Linkage

Not functionally linked to any very highly valued habitat in close proximity.

Potential Value

Low.

Nursery /Breeding Ground

None

Age

Young (<10 years)

Abundance/ Richness of Wildlife

Low abundance / richness of fauna

Overall Ecological Value

Low to moderate
