Christina Carrero conducts threat assessments of tree species around the world for the International Union for Conservation of Nature (IUCN) Red List. Threat assessments are focussed in oak diversity hotspots, primarily Mexico/Central America and Asia, as well as on the trees of the US. Through literature reviews and information gathered from expert sources, species are assessed to categorize their threat of extinction, then are assigned conservation recommendations appropriate for their needs. Coordination with conservation organizations based in Central America and Southeast Asia allows these recommendations to be put into place.
These projects are in collaboration with the Global Trees Assessment initiative, led by Botanical Gardens Conservation International (BGCI) and IUCN. The goal of this initiative is to assess all of the world’s tree species for threat status by the year 2020.
Christina also assists in evaluating applications for ArbNet’s Arboretum Accreditation Program. ArbNet’s accreditation program, a collaboration between the Morton Arboretum, BGCI, the Global Trees Campaign, and the American Public Gardens Association, is the only international accreditation standard for arboreta.
In Sue’s role as ArbNet Coordinator she works with the arboretum community worldwide developing communication channels and facilitating information exchange, collaboration, and dialogue. Sue also coordinates the ArbNet Arboretum Accreditation Program that focuses on quality, standards, and thresholds providing guidelines, models, expertise, and inspiration so that the entire arboretum network is stronger, more connected, and together is advancing the quality and capacity of tree-focused gardens.

Dr. Alvarez-Clare’s research focuses on understanding the links between the carbon and nutrient cycles and how resource availability can influence biological processes, plant functional traits, and biodiversity preservation. As an ecosystem ecologist with a background in tree ecophysiology and biogeochemistry, she combines long-term monitoring, manipulative experiments, and innovative analytical techniques to examine patterns, processes, and mechanisms that will advance our understanding of how changes in the resources required by trees will affect plant-soil-microbial feedbacks. Most of her work has been conducted in tropical forests but as the Center for Tree Science Academic Mentor, Dr. Alvarez-Clare has the opportunity to actively work with CTS Undergraduate Research Fellows and other students involved with CTS and learn about temperate ecosystems both in a natural and urban context.
In addition to being the academic mentor for undergraduate research at the Center for Tree Science, Silvia Alvarez-Clare is a guest researcher at Argonne National Laboratory. Her research in tropical ecosystems ecology has been funded by The National Science Foundation’s Doctoral Dissertation Enhancement Grant (DDEG) and Postdoctoral Research Fellowship in Biology (PRFB), and her work published in top tier journals such as Ecology Letters and Ecology. Alvarez-Clare is the co-leader of a local group that supports Women in Science and is part of the Tree Board for North Central College.
