We experience changes whose duration we note and measure as though they were all – or even anything. But we experience as well a continuing present which neither we nor the Mayas approach or depart from, a present which neither develops nor declines. It is there. The changes do not express it.

Abstract

At the end of 2019, Botanic Gardens Conservation International (BGCI) proposed a new initiative to protect trees: Global Conservation Consortia, each focused on a specific group of plants of special interest. To date, eight such Consortia have been created, coordinated by BGCI, with the one for oaks led by the Morton Arboretum.
