An immensely talented team of researchers has contributed to the data collected on CHEP lands since 1998. Some studies were one-time assessments—like the historical geography of the Guthrie-Bancroft parcel. Others, like the herpetological and bird inventories, occur annually.

Since its inception, the CHEP research project has steadily evolved. In 2007, CHEP established a weather station to record temperature, precipitation, and other basic atmospheric measurements. And in 2009, Marc Lapin began studying wildflower phenology (the chronology of the

appearance and growth of spring wildflowers). In this era of

accelerated climate change, these additions will provide information on the relationship between climate and cyclical biological phenomena.

Marc Lapin, project manager

Marc Lapin, CHEP project manager and ecologistWhen ecologist Marc Lapin attended Middlebury College, he took Professor Steve Young’s course in Introduction to Polar Environments. The course inspired him to visit Alaska, and like any good pilgrimage, that journey offered far-reaching revelations. “While backpacking in Denali National Park,” Marc says, “I realized that my life’s work would be in nature conservation. Ever since, I’ve devoted myself to that.”

That devotion led him to masters studies at the University of Michigan and doctoral studies at Cornell University. Since moving to Vermont in 1991, he’s worked closely with the Vermont Natural Heritage Program and The Nature Conservancy, and coordinates the Champlain Valley Clayplain Project. He has also come full circle, returning to Middlebury College to teach as an Associate in Science Instruction in Environmental Studies.

Marc has brought his passion for ecological mapping to his work as team leader for the Colby Hill Ecological Project. The opportunity to document long-term change in a typical Green Mountain landscape intrigued him. “The forest [monitored by CHEP] has been worked hard—plenty of it was cleared for pasture—but as it has returned and recovered, it shows the plant composition differences one would expect based on soils.”

The data of six years of field research reveal distinct assemblages of plants, insects, spiders, small mammals, and more within the 716-acre study area—differences caused by small changes in moisture, nutrients, and temperature. “That’s why I love ecological mapping,” he says. “Because I get to see and think about those differences and document them, even before I may know what their significance is.”

Pondering the legacy of CHEP, Marc says, “I hope that the legacy is a long, long period of learning about the land and its family of organisms. It will reveal many mysteries to us over the decades. Ecologists of the future will be thankful for the data we are collecting and the permanent sampling plots that will show how the forest is changing.”

Susan Morse

Sue Morse, CHEP wildlife habitat researcherCoast to coast and from British Columbia to Mexico, Susan Morse is highly regarded as an expert in carnivore tracking and natural history. She has been an active participant in Western Forest Carnivores Committee meetings and is a founding member of the Northeast Carnivore Conservation Working Group. Her research has focused on cougar, bobcat, black bear, and Canada lynx. She has given workshops on wild felids and other carnivores to a wide range of audiences, from the general public to wildlife experts.

Sue founded and serves as Program Director for Keeping Track, an organization devoted to training professional biologists and citizen scientists alike in wildlife monitoring skills. Keeping Track's mission is to empower multiple stakeholders to use their knowledge to detect, record and monitor the status of wildlife and wildlife habitat in their communities. Data collected by Keeping Track teams has influenced the conservation of over 30,000 acres of habitat in twelve states and Quebec.

Barry and Warren King

Jeffrey Collins, Mark Ward, and Susan Young

After countless hours sorting and classifying thousands of specimens, CHEP researchers Mark Ward, Jeffrey Collins, and Susan Young released their final report on surface-active terrestrial invertebrates on CHEP-monitored lands. Between 1999 and 2002, the bug team collected 11,990 specimens in 107 subsamples. The collected invertebrates represented seven phylogenic classes and 22 orders. Researchers identified 5,761 specimens to the family level, accounting for 101 invertebrate families.

Of the nearly 12,000 invertebrates collected, 6,073 were mites (order: Acarina). The orders with next highest number of specimens were the springtails (Collembola) and the beetles (Coleoptera). The order Coleoptera was represented by the largest number of families (22).

What is the upshot of all these numbers in layman's terms? As Ward, Collins, and Young state in their report, Terrestrial invertebrates are low on the food chain and thus respond more rapidly to subtle environmental changes than vertebrates. In small preserves, invertebrates offer a way of monitoring ecological integrity that may not be feasible with relatively small vertebrate populations.

The baseline data on invertebrates present on CHEP lands—which are typical of much of the landscape in this part of the western Green Mountains—can help scientists track the region's ecological health.
