在深水灣谷的海邊馬兜鈴群落現時尚未受到逼切的威脅，但由於該物種容易受到發展工程影響，任何在深水灣谷範圍以內或附近的發展計劃都有可能對當中的群落構成威脅。
The existing population of A. thwaitesii at the Site is not subject to immediate threat. However, as the species is vulnerable to development imapct, any development proposal within and in the vicinity of the Site may pose threats to the population in the valley.
