The Sky Oaks Field Station (California) is one of the longest-running FLUXNET, Ameriflux, and SpecNet research sites, heavily instrumented to be able to measure carbon, water and energy fluxes in two stands of chaparral, one 11 years of age and one over 100 years old. The 6 July 2003 Coyote wildfire destroyed all of the instrumentation at both sites. This proposal seeks funding to immediately replace a "tram system" for optical and thermal sampling that will allow for a quantitative assessment of the controls on carbon flux immediately after fire. In addition, funding will permit installation of a wireless sensor network and the ability to conduct spatially-explicit sampling of biomass, species composition, pigment composition, water status and carbon fluxes via respiration and photosynthesis. Recovery of vegetation is expected to be rapid, and immediate deployment of a tram system and of the wireless sensor network allows a unique opportunity to initiate a long-term study to evaluate controls on carbon, water, and energy flux in a chaparral ecosystem beginning soon after fire.

天空橡树野外站（加州）是运行时间最长的FLUXNET，Ameriflux和SpecNet研究站点之一，配备了大量仪器，能够测量两个查帕拉尔林分的碳，水和能量通量，一个11岁，一个超过100岁。 2003年7月6日，Coyote野火摧毁了两个站点的所有仪器。 该提案寻求资金，以立即取代光学和热取样的“电车系统”，以便在火灾后立即对碳通量的控制进行定量评估。此外，资金将允许安装一个无线传感器网络，并有能力对生物量、物种组成、色素组成、水状况和通过呼吸和光合作用的碳通量进行空间明确的采样。 植被的恢复预计将是迅速的，电车系统和无线传感器网络的立即部署允许一个独特的机会，开始一个长期的研究，以评估控制碳，水和能量通量在查帕拉尔生态系统火灾后不久开始。
