Por padrão savetreescarrega titleseco que não é compatível com amsart.
Carregue-o com a sections=normalopção, então titlesecnão será carregado.
\documentclass{amsart}
\usepackage[sections=normal]{savetrees}
\usepackage{kantlipsum}
\begin{document}
\section{foo}
\kant[1-3]
\section{baz}
\kant[4-6]
\end{document}
Por outro lado, você obtém essencialmente o mesmo layout sem savetrees:
\documentclass{amsart}
\usepackage{kantlipsum}
\addtolength{\textwidth}{170pt}
\addtolength{\textheight}{140pt}
\calclayout
\begin{document}
\section{foo}
\kant[1-3]
\section{baz}
\kant[4-6]
\end{document}
