Around the world, ecosystems are collapsing as trees are logged and forests disappear. Large-scale reforestation efforts aim to reverse this decline—but how successful are they? 


ÃÀ¼§ÉçÇø Participants hike through the forest to the research site (C) Mary RoweThe Serra dos Órgãos mountain range of Rio de Janeiro State is a striking landscape of spectacular ridges, valleys, and lowlands, stretching from magnificent mountain summits to mangrove forests on the coast. Nestled in these lowlands, the Reserva Ecológica de Guapiaçu (REGUA) is a biodiversity hotspot teeming with life—including at least 60 mammal species such as the elusive southern woolly spider monkey, powerful pumas, majestic tapirs, and social capybaras.

Yet this extraordinary ecosystem is under immense pressure. Only 15% of the original forest remains, much of it fragmented and disconnected. In response, conservationists, NGOs, and the Brazilian government have launched large-scale reforestation efforts to restore this critical habitat. But for these efforts to succeed, they must be guided by sound scientific data to ensure they support the species and ecological functions of the forest.

On this project, you will investigate small, medium, and large mammals in REGUA, from the common southern four-eyed opossum to the rarely seen puma. Using both live traps for small to medium animals and camera traps for larger animals, you will collect information about how the mammals of the reserve are responding to reforestation efforts. This project will actively contribute data to the management plan of REGUA and produce technical reports for reforestation decision-makers. Beyond research, you’ll get hands-on with conservation by helping to grow native seedlings—and may even plant them in the forest yourself.

HOW WILL YOU HELP

When you arrive, the researchers will conduct an orientation and inform you about the areas you will be studying. Fieldwork includes some of the following tasks:

.

A participant helps ÃÀ¼§ÉçÇø lead scientist, Dr. Muanis install a camera trap on a tree (C) Mary Rowe
Conduct mammal surveys

You will install camera and live traps, check the traps, assist staff in processing small mammals, collect and clean traps, and enter the data collected.

CONDUCT REFORESTATION ACTIVITIES

You will aid in reforesting the Atlantic Forest area by participating in various nursery tasks. You may harvest seeds from the forest, process seeds, prepare soil bags, organize the nursery by species, de-weed seedlings, or plant tree seedlings (specific tasks are season—and weather-dependent).

MEASURE THE SUCCESS OF REFORESTATION

(The following activities can only happen during the dry season on July teams). You will mark trees and plots on reforestation banks, take field measurements of trees and their conditions, including stand density canopy coverage, and assess tree growth rates. 

Field conditions and research needs can lead to changes in the itinerary and activities. We appreciate your cooperation and understanding.

After being picked up at the airport and driven to REGUA with my teammates, I was introduced to the room where I would be sleeping.  I was very nervous that I would be waking up to spiders, scorpions, and/or other insects/animals during this trip.  The accommodations were clean and no problems occurred during my stay.  The food was excellent and prepared fresh for every meal.  The weather (winter in Rio) was great - 70-80F during the day and into the 50s at night.  The staff was amazing. Each day, we would wake up, eat breakfast, take the truck (20 minutes) to the study sight, and check the humane traps for any small mammals that we may have caught.  If caught, the lead scientist and/or field assistant would restrain the animal while measurements were taken and the data was written down.  The health of the animals was always at the forefront and they were handled and released very safely.  In the afternoons we would either hike and learn about the forest or help with the preparation/growth of saplings to be used in reforestation.  There was time each day to sit by the water and watch the waterfalls.  We took a 2-hour hike to an incredible waterfall, Swallow's waterfall, that looked like a scene right out of Jurassic Park.  We learned about the history of REGUA and went over the data from the research.  In addition, there was time to birdwatch, see capybaras, marmosets, and sloths, and hike the conservancy.  The scenery is stunning.  A trip that I would recommend to anyone - even if you are worried about spiders and scorpions.

I was very excited to be returning to Brazil for a second ÃÀ¼§ÉçÇø project and “Wildlife and reforestation of Brazil, was all that I’d hoped, from the warm reception we received from our hosts, to the brilliant birding that greeted us every day, to the nonchalant tapir that ambled by on a morning walk, to the delicious local food and the astounding beauty of the area. The project staff was passionate about the local wildlife and it was heartening to see the care with which the monitored wildlife was treated. If a staff member felt an animal was overly stressed by the trap, it was released immediately and all animals were returned to exactly where they were trapped for release. The Atlantic Forest has shrunk so much over the years, so I feel very encouraged by the visible progress that has been made in taking back this land for the forest and its creatures.

I've been on quite a few ÃÀ¼§ÉçÇø expeditions over the years, and I must say this one ranks as one of the best. Brazil was a new experience for me, and I found the Atlantic Rain Forest to be a mystical place. Just a handful of miles outside of Rio de Janeiro, the expedition camp facility is insulated from the rest of the world. It is a peaceful retreat that offers good food and lodging. Surrounded by the lush vegetation of the Atlantic coastal range. We spent our working days trekking the forested trails searching for the small mammals that inhabit this region. Manoel, our expedition's Principle Investigator, patiently answered our questions and pointed out the exotic Flora and Fauna during our morning research surveys. Later in the day, we were back at the lodge, taking part in the efforts to reforest the recently cleared areas for farming. This effort was particularly satisfying when you saw how much of the landscape had been restored to its natural state through the efforts of these individuals. Nightly dinners allowed us to meet and exchange tales of our daily wonderings with other researchers and guests. Truly a rewarding experience that gives you the feeling that your efforts are making a difference.

Why are we replanting the Atlantic Forest?

The Atlantic Forest, Brazil's second-largest rainforest behind the Amazon Rainforest, is today just 10% of its original size, but hopefully, that’s changing…
