• Survey and observe birds. You'll check nest boxes set up by the researchers throughout the mountains, and learn to identify birds by their songs.
  • Track biodiversity. On your long-hike days, you will take note of all the plants and animals you see and monitor camera traps set up by the researchers.
  • Monitor small mammals. Keep an eye on the health of vole, mouse, and shrew populations by capturing them, collects measurements, and safely releasing them.
  • Survey bats. On some evenings, you will walk paths and count all the bats you see or detect with special sensors.
  • Assess vegetation. In preset research plots, you will measure trees and record the timing of natural events like fruiting and flowering.

In the high slopes of the French Pyrenees, as in other mountain regions, climate change has already begun to alter the landscape. Some species are moving to higher latitudes, and some have begun to decline. The ways humans use the land also causes shifts in the natural order of things, but little research has been done on how people have impacted this particular place. Questions of how climate change and human encroachment continue to alter this alpine world need answers as local organizations work towards sustainable solutions.

Trip Description

While trekking through this striking landscape, you’ll be among the first to search for these answers. Not much is known about the amazing biodiversity of the forests and alpine meadows, and your team will help identify the key species in the ecosystem and how they are changing. You will weigh and measure small mammals, find tawny owls and other bird species by spotting their nests and listening for their songs, observe bumblebees as they visit flowering plants, and detect bats. These tasks will help researchers find out how animals are faring, and how to best manage for key species such as the brown bear. The research will also help determine when natural events, like plant flowering and pollination, are occurring. Understanding the timing of such processes can help scientists learn if species’ life cycles are becoming out of synch with each other, which could have serious consequences for the health of this ecosystem.


Daily Life in the Field

Our days in this stunning environment will vary. Sometimes you’ll work at a research site close to home, and on other days you'll walk amidst the mountains at high elevations. Throughout the expedition, you'll see much of the countryside, from wooded mountainsides to quiet valleys and open pastures. You will help:


Monitor small mammals. Keep an eye on the health of vole, mouse, and shrew populations by capturing them, collecting measurements, and safely releasing them.


Track biodiversity. In each of the 12 sampling stations, you will take note of all the plants and animals you see, check some of the more than 100 nest boxes for birds and owls installed, and monitor camera traps set up by the researchers.


Follow daily growth of tree species (Pinus uncinata) along the elevational gradient using high-tech equipment.


Survey endangered vegetation of the currently disappearing natural snowbeds, and study how artificial snow is affecting the accompanying vegetation.


In the late afternoon, the team will return to the hotel to rest, record data, and identify photos of animals taken by camera traps. Evenings will include a communal dinner and time to rest, see some local sites, or learn more about the research.


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