31. Undergrowth Clearing. In all parts of the Colony, the total area cleared in connection with anti-malarial work was 3,764,605 square feet; other areas cleared in connection with the formation of catchments, reservoirs, roads, buildings and general public improvements amounted to 8,620,695 square feet.
32. Preservation of Local Flora. Many of the uncommon flowering plants on the Island have been greatly reduced in number and are now in danger of being completely destroyed, chiefly owing to the extensive development of outlying areas of land which is being carried on. Other causes are the depredations of plant hawkers, medicinal herb collectors and thoughtless flower pickers. Ferns have also suffered, notably Asplenium Nidus, which was, until a few years ago, numerous on rocks in many nullahs, and has now almost entirely disappeared.
33. In order to prevent the threatened destruction, a commencement was made with the scheme of removal; 363 plants of the terrestrial Orchid Plantanthera Susannae, Lindl. and 686 of Iris speculatrix, Hance, were lifted in various parts of the Island and replanted in suitable spots in Mount Collinson Prohibited Area, where, it is hoped, they will be allowed to remain undisturbed.
34. Lantana Destruction. Both local species of this plant, which flourish in the poorest of soil, are rapidly increasing in all parts of the Colony. Large areas were cleared of the plants during the year.
35. The Entomologist, Board of Commissioners of Agriculture and Forestry, Territory of Hawaii, kindly supplied this Department with a consignment of the Lantana Seed Fly and the Lantana Plume Moth. Both insects are Lantana parasites, the former attacks and destroys the unripe seed and the latter destroys the unopened flower buds. The insects were liberated on July 21st in suitable spots. So far there is no evidence as to whether they have survived.
AGRICULTURE ETC.
36. Fan Ling Experimental Garden - Cajanus indicus, grown as a shade plant, did not give sufficient protection to the plots of Citrus and Avocado Pear (Persea gratissima) in the recently formed extension; both were lifted and replanted in the old portion of the garden; the Avocado Pears were shaded by planting alternately with Bananas and soon commenced to make rapid growth. A plot of foreign vegetables, all of which can be raised and harvested during the season when land is not required for Padi, was grown for demonstration purposes and for exhibition at the New Territories Agricultural Show.
