Pilot project
helps scientists, managers, and conservationists pro-actively prepare for a
changing climate
Researchers
have successfully piloted a process that enables natural resource managers to
take action to conserve particular wildlife, plants and ecosystems as climate
changes.
The Adaptation
for Conservation Targets (ACT) framework is a practical approach to assessing
how future changes in air and water temperatures, precipitation, stream flows,
snowpack, and other environmental conditions might affect natural resources.
ACT enables scientists and managers to work hand-in-hand to consider how management actions
may need to be adjusted to address those impacts.
"As
acceptance of the importance of climate change in influencing conservation and
naturalresource management increases, ACT can help
practitioners connect the dots and integrate climate change into their
decisions," said WCS Conservation Scientist, Dr. Molly Cross. "Most
importantly, the ACT process allows practitioners to move beyond just talking
about impacts to address the 'What do we do about it?' question."
The ACT
framework was tested during a series of workshops at four southwestern United
States landscapes (see map) that brought together 109 natural resource
managers, scientists, and conservation practitioners from 44 local, state,
tribal and federal agencies and organizations. The workshops were
organized by the Southwest Climate Change Initiative, representing The Nature
Conservancy (TNC), the Wildlife Conservation Society (WCS), Climate Assessment
for the Southwest (CLIMAS), the Western Water Assessment, the U.S. Forest
Service, and the National
Center for Atmospheric
Research.
One example
comes from the Bear River basin in Utah ,
where workshop participants looked at how warmer air and water temperatures and
decreased summer stream flow might affect native Bonneville cutthroat trout
habitat and populations. The group strategized that restoring the ability of
fish to move between the main stem of the Bear River
and cooler tributaries, protecting cold-water habitat, and lowering the depth
of outflow from reservoirs to reduce downstream water temperatures could help
maintain or increase trout population numbers as climate changes.
Participants
in another workshop considered the impacts of reduced snow-pack and greater
variability in precipitation on stream flows in the Jemez
Mountains of New Mexico . To maintain sufficient water in
the system and support aquatic species and riparian vegetation, attendees
identified options such as restoring beaver to streams, building artificial
structures to increase the storage of water in floodplains, and thinning the
density of trees in nearby forests to maximize snowpack retention.
"The ACT
process helps workshop participants move beyond the paralysis many feel when
tackling what is a new or even intimidating topic by creating a step-by-step
process for considering climate change that draws on familiar conservation
planning tools," Cross said. "By combining traditional conservation
planning with an assessment of climate change impacts that considers multiple
future scenarios, ACT helps practitioners lay out how conservation goals and
actions may need to be modified to account for climate change."
The results
will help land managers as well as people. "Climate change impacts
livelihoods and threatens the water supplies of many of our communities,"
says Terry Sullivan, The Nature Conservancy's New Mexico state director. "We hope
that this tool will be utilized to help make decisions which will lead to
healthy and sustainable watersheds, and ultimately sustain water supplies for
farms and cities."
ACT workshops
have been used to launch climate change planning at 11 locations in the United States for more than 15
wildlife, plant, and ecosystem targets (for details seehttp://www.wcsnorthamerica.org/ConservationChallenges/ClimateChange/ClimateChangeAdaptationPlanning.aspx).
Feedback given by workshop attendees indicates that the ACT approach was
successful in increasing participants' capacity to address climate change in
their conservation work.
"We need
to see more practitioners applying approaches like ACT if biological diversity
and ecosystem services are to be maintained in a rapidly changing world,"
Cross added.
Results from
the workshops are published in the February 2013 volume of the journal
Conservation Biology (available at http://onlinelibrary.wiley.com/doi/10.1111/j.1523-1739.2012.01954.x/pdf).
