Drought, ozone (O₃), and nitrogen deposition (N) alter foliar pigments and tree crown structure that may be remotely detectable. Remote sensing tools are needed that pre-emptively identify trees susceptible to environmental stresses could inform forest managers in advance of tree mortality risk. Jeffrey pine, a component of the economically important and widespread western yellow pine in North America was investigated in the southern Sierra Nevada. Transpiration of mature trees differed by 20% between microsites with adequate (mesic (M)) vs. limited (xeric (X)) water availability as described in a previous study. In this study, in-the-crown morphological traits (needle chlorosis, …

In December of 2012, the President’s Council of Advisors on Science & Technology (PCAST) issued a report to the President on Agricultural Preparedness and the Agriculture Research Enterprise. The PCAST report recognizes the long-term history of public investment in agricultural research. The report also recognized significant private investment into agricultural research. Significantly, the report is adamant that the agricultural research enterprise is not prepared to meet the challenges of the 21st century. The report cited two reasons:

1. too little competitive research and
2. an imbalance of research priorities between private and public funding sources.

This report addresses the latter issue.
