Water residence time of ridge-top trees was studied using the deuterium tracer technique combined with sap flow in 2012. Trees were injected with deuterium tracer and the tracer was measured in leaf condensate on subsequent days. Leaves were sampled regularly by climbing trees and 50 foot tall scaffolding.2012年，研究者们采用氘同位素示踪技术与树液流量相结合的方法，对山顶脊树木的水停留时间进行了研究。树木被注入氘同位素示踪剂，随后数日对其叶片凝结水中的示踪剂进行测量。研究者通过攀爬树木及使用50英尺高的脚手架，定期采集叶片样本。
