1. INTRODUCTION

1.3 Structure of this Document

Succeeding this introductory section, the remainder of this Report is presented as follows:

n Section 2 details the monitoring results, including the key maintenance activities conducted this reporting month;

n Section 3 presents the succeeding post-transplantation monitoring schedule; and

n Section 4 summarizes the findings of the post-transplantation monitoring and way forward.

2. MONITORING RESULTS

Following the transplantation works on 10 November 2022, the 1^st post-transplantation monitoring and audit was carried out on 24 November 2022 to check the condition of the transplanted plant individuals.

2.1 Condition of the Transplanted Individuals

2.1.1 The transplanted individuals, i.e., two nos. of saplings of the Incense Tree Aquilaria sinensis, one cluster of Lamb of Tartary Cibotium barometz, and about 19 clusters of Bottlebrush Orchid Goodyera procera were generally in fair to good condition. The Lamb of Tartary, however, exhibited discoloration and wilting of leaves. Albeit strict compliance of the transplantation works and post-transplantation maintenance to the approved Transplantation Proposal, transplanted individuals would require time to adapt and establish in the new environment/substrate of the receptor site. Hence, signs of leaf discoloration and/or wilting, dehydration, and even die-off are expected. Thus, succeeding post-transplantation maintenance and monitoring and audit are crucial to assess the progress of recovery and establishment of transplanted individuals in the receptor site.

2.1.2 The numbers, measurements, and health conditions of the transplanted plant species of conservation importance during the current monitoring period are shown in Appendix A.

2.1.3 The photographic records of the transplanted plant species of conservation importance during the current monitoring period are shown in Appendix B.

2.2 Key Maintenance Activities Conducted in The Reporting Month

2.2.1 The key maintenance activities carried out for the current reporting month are the following:

n Daily watering of the Incense Tree saplings and Lamb of Tartary at least for the first week of post-transplantation works and reduced to 2-3 times per week during the succeeding week. The watering dates were 11-17 Nov for the first week after transplantation and 21 Nov and 23 Nov for the succeeding week.

n Once a week watering of Bottlebrush Orchid. The watering dates were 11 Nov, 17 Nov, and 24 Nov.

n Manual removal of weeds when observed during watering activities; and

n Checking of insect attacks and/or fungal infestation during watering activities.

n Prevention of human disturbance by fencing off area around the two Incense Tree saplings Aquilaria sinensis.

2.3 Recommendation on Post-Transplantation Maintenance

Immediately after the monitoring and audit activity, the following post-transplantation maintenance was discussed with the Contractor for their prompt implementation:

n The watering frequency for the two saplings of Incense Tree should be increased to 3-4 times a week.

n The watering frequency of the cluster of Lamb of Tartary should be reduced to once a week.

n The watering frequency for all 19 clusters of Bottlebrush Orchid should remain the same. During watering activities, the surrounding weeds and decaying leaves should be removed.

3. POST-TRANSPLANTATION MONITORING SCHEDULE

3.1.1 As per Section 10.3 and Table 10.1 of the EM&A Manual, the survival and growth of the transplanted species will be monitored by a qualified ecologist or botanist at least twice a month during the first three months after transplantation and once a month in the following nine months.

3.1.2 As only one monitoring activity will be conducted in November, the forthcoming monitoring and audit activities will be conducted twice a month for December, January and February. Then, the monitoring activities will be conducted monthly until October 2023.

3.1.3 The need for any further monitoring will be reviewed and determined according to the monitoring results of the 12-month monitoring.

4. SUMMARY AND CONCLUSION

The health of the transplanted individuals of Incense Tree and Bottlebrush Orchid ranged from fair to good condition. Minor health issues such as diebacks were observed on the two Incense Tree saplings but overall, these two saplings were still under fair health conditions. Moreover, some clusters of Bottlebrush Orchid manifested mild health issues such as slightly chlorotic and wilted leaves, but their health conditions were still fair overall. The transplanted cluster of Lamb of Tartary, however, seemed to exhibit poor health condition as some of its leaves were showing discoloration and have already wilted. It is recommended that more attention should be focused on the post-transplantation maintenance of the Lamb of Tartary.
