Reserve, Tristania conferta, Aleurites Fordii, Acacia confusa, Cunninghamia sinensis, Pithecolobium Saman, Cinnamomum Camphora, Ginkgo biloba, Celtis sinensis and Glyptostrobus heterophyllus.
The planting of roadside trees for shade and decorative purposes was maintained and extended during the year; a large number of trees were killed or damaged by the gale of August 20th and could not be replaced before the end of the year; the force of the gale did most damage between Castle Peak and Sheung Shui, where many fine specimens of Melaleuca Leucadendron were destroyed.
Trees Felled.-Increased motor traffic necessitated the removal of a number of large shade trees from the sides of the motor roads.
Other felling was carried out in connection with the development of building sites, the formation of dairy farms and the leasing of the necessary grass-growing areas adjoining the farms, extensions of cemeteries, and work in connection with reservoir catchment areas.
Miscellaneous Planting.-Planting of shade and flowering trees, shrubs, and creepers was carried on in a large number of otherwise unused small open spaces in all parts of the Colony.
Undergrowth Clearing.-Anti-malarial clearing has now been extended to Tai Po district, where systematic removal of undergrowth is carried out in the vicinity of houses and public buildings twice annually.
During the year, the total areas cleared in connection with anti-malarial measures totalled 8,905,835 square feet; for other purposes, such as surveys, training of nullahs, and other public improvements, the areas cleared amounted to 2,642,305 square feet.
Insect Pests.-Pine Tree Caterpillars (Eutricha punctata) appeared in the Pine plantations in many parts of the Colony in March and were in evidence at the end of the year; serious damage was done to Pine trees during the month of June. Collection and burying of the caterpillars were commenced when there was no longer any hope of weather conditions destroying the pest; the total amount collected and destroyed in all parts of the Colony was 14,637 pounds.
Protection from fire.-A total of 30 hill and plantation fires occurred during the year; no serious damage was done to any Government plantation, but large numbers of wild trees on the slopes of Tai Mo Shan were destroyed. Little or no assistance in dealing with fires was given by village people living within short distances of the burnt areas; most of the fires appeared to be due to the careless dropping of lighted tobacco or matches.
