Observation Period

ABSTRACT Diurnal raptors were counted during their southward migration in autumn of 2019 at Kenting National Park, southern Taiwan, an important hawkwatch site along the East-Asian Oceanic Flyway. Observations were conducted from 1 September to 31 October 2019 in the morning hours, but the observation period was extended to 1400 H whenever large numbers of raptors passed the site before noon. A total of 329,559 individuals of 14 migratory raptor species was recorded. The Chinese Sparrowhawk (Accipiter soloensis) and Gray-faced Buzzard (Butastur indicus) made up 78.3% (257,971 birds) and 21.6% (71,045 birds) of the total, respectively. The number of Chinese Sparrowhawks increased significantly when we extended the survey duration from 1200 H to 1400 H (paired t-test, t = 2.44, P = 0.04), but the number of Gray-faced Buzzards did not (t = 1.94, P = 0.09). Thus, Chinese Sparrowhawks may continue passing the site en route to the Philippine Islands in the afternoon hours, whereas Gray-faced Buzzards usually stop migrating in early afternoon, at least under certain conditions. How prevailing wind conditions along the East-Asian Oceanic Flyway in autumn shape the different migratory strategies of these two hawk species requires further study.

The Impact

The hydrodynamic and water quality models (the Delft3D model) were established based on the measured data and the estimated pollution discharges from Dinh Vu industrial zones to Nam Trieu estuary. With seven separate simulation scenarios, the results show that in case of increased wastewater with the control of pollution discharge (water and concentration), the impact of pollution is only limited to a small area around the discharge point. Their influences on water quality in other areas in Nam Trieu estuary are quite small. Meanwhile, in case of environmental risk, a strongly increasing pollution load would cause the significantly increasing pollutant concentration in this area, they have almost exceeded the value in the National Technical Regulation on surface water quality (QCVN 10-MT:2015/BTNMT), such as NH4, COD, and BOD. Dissolved oxygen in the water would also decrease significantly. The spatial influence extends from the discharge point to Nam Trieu estuary, inside Cam, Bach Dang rivers, and Cat Hai coastal area.

Chemical Water

Silt loads in the Olifants and Sabie river systems inside the Kruger National Park, were monitored by collecting water samples every consecutive week for a period of 20 months. The variation in silt concentration, changes in selected physico-chemical water quality variables and fish mortalities during flushing (i.e. release of silt, by sluicing) of the Phalaborwa Barrage, were also monitored. The Olifants River inside the Kruger National Park carried high silt loads in summer; in the dry season the suspensoid load was greatly reduced. A similar pattern was observed in the Sabie River, but the silt loads were generally lower. It was apparent that silt loads released from the Phalaborwa Barrage led to large variations in the natural silt loads of the Olifants River. These increased amounts of silt (25 000 mg/1 to >70 000 mg/1) caused drastic reductions in the dissolved oxygen concentration of the water, ranging from >6 mg/1 to 0 mg/1. Depending on the severity and duration of the flushing, fish succumb to such silt loads. These findings, as well as published information, indicate that the management strategy of flushing to improve storage capacity is ecological unacceptable. It is therefore suggested that the use of the Phalaborwa Barrage as a future reservoir should be critically re-evaluated.

The Impact

In order to investigate the impact of the 1988 fires on the chemistry and water quality of shallow ground water in Yellowstone National Park, a two­year program of sampling and analysis was begun in August, 1989. Samples from ground-water wells for which pre-fire chemical data could be obtained were selected for this study. Although it may have been anticipated that the surface waters would show some effects of fire, in terms of increased sedimentation and the addition of ash-laden runoff, the effects of the fires on ground water are less predictable. The purpose of this investigation is to determine the character and extent of these effects.

The objective of this research is to provide a detailed analysis and assessment of the impact of the 1988 forest fires on the chemistry and water quality of shallow ground water in Yellowstone National Park. Specific objectives for the first five months of this study (August through December, 1989) included: (1) review of existing data on the chemistry of ground water at selected sites in Yellowstone National Park, (2) selection of suitable sampling sites and initial rounds of sample collection and analysis, (3) continued literature search for comparable or complimentary studies, (4) establishment of professional contacts within the park, other universities, and within the U.S. Geological Survey.

This paper presents the results of field work conducted between 1994 and 1996 to establish the occurrence, and population, breeding and conservation status of bats in and around Kenting National Park, southern Taiwan. Of the 20 bat species that occur in Taiwan, Kenting National Park and its vicinity harbour eight species; three are endemic to Taiwan and two are endemic subspecies. Six of the eight species roost in natural caves and man-made tunnels. Two species of forest bats were captured during mist-netting. The most predominant species were the horseshoe bat Rhinolophus monoceros and the common bent-winged bat Miniopterus schreibersii. The major threat for the cave-dwelling bats around Kenting is the closure of cave entrances by farmers. Recommendations are given for conserving the bats and their habitats in Taiwan.
