(I) Physical CharacteristicsHulu Gombak Forest ReserveThe Hulu Gombak Forest Reserve is located on the north side of the Kuala Lumpur-Bentong road at Mile 22. The road forms one boundary of the reserve, the Selangor-Pahang State boundary and Compartment 21 of the reserve the third. The topography is rough, mostly steep hillsides and narrow valley bottoms.Sungai Gombak, as main river, traverse the north part with tributaries such as Sungai Rumput, Sungai Pisang, Sungai Gapis and Sungai Tiang. Forest on terrain between 305 -610 m asl. The highest point is Gunung Bunga Buah (1,430 m asl). Areas below 152 m asl is developed. On the southern part, smaller rivers such as Sungai Seleh, Sungai Pemulas and Sungai Songlai are tributaries of Sungai Kelang which flows into the Klang Gates reservoir. The highest point in this section is Bukit Repin (1,341 m asl). The area is generally between 152 - 457 m asl. The forest reserve lies on granite and limestone overlaid by Quarternary alluvium and is covered in red-yellow ultisol soil. Klang Gates Wildlife SanctuaryThe Klang Gates Ridge is a massive quartzite vein which runs east of Kuala Lumpur in a west north-west to west direction from Sungai Batu to the Ampang Hills. The ridge is about six miles in length. Sheer cliffs, free of vegetation, rise above the surrounding forest, in some places with a rock face about 120 m high, in other places it is divided by wind gaps. The ridge top is a jagged knife edge, in some places only a few feet wide, with precipitous drops on either side. The highest point is 280 m asl. Lowland dipterocarp forest surrounds the ridge.(II) Climatic ConditionsThroughout the year, rainfall averages about 50 mm per week with heavier rains in November and December. The valley experiences dry season between January-February. Temperature averages about 21oC annually (McClure, 1974).
