Many organizations focus on a wide variety of climate and related environmental causes. In Working with Other Organizations and Allies we explore how to engage and partner with other organizations in a respectful, understanding and productive way.
Join CCL leaders to listen to ideas and examples from throughout the country of what chapters are doing to build these essential connections as well as understanding how to best interface with local groups of national green organizations.

Threat to trout. Useful for speaking to Trout Unlimited members and conservative fishermen.
PRESS RELEASE
International Scientists Report Global Imperilment of Trout and Call for Action to Reverse Declines
May, 2019 – Granada, Spain
Nearly three quarters of the planet’s trout species are at imperiled and at risk of extinction, scientists say.
Scientists from more than 25 nations, and across 5 continents gathered last week in Granada, Spain, to report on the global status and threats to trout, Â (www.salmonidsymposium.es), one of the most culturally, economically, and ecologically important groups of freshwater fishes worldwide.
“Of the 124 known species of native trout from 52 countries across the Northern Hemisphere, 73% are threatened with global extinction, and this trend is expected to accelerate massively in the years ahead, according to lead study author Clint Muhlfeld.
These cold-water specialists provide recreation and food to millions of people and are excellent indictors of freshwater health. “Despite their importance as societal icons and as indicators of biodiversity, many of the world’s trout species and are in peril on a global scale,” said Javier Lobon-Cervia of the National Museum of Natural Science - Madrid and Convener of this conference.
Human destruction of habitats, overfishing, pollution, dams, and global warming all contribute to their decline and imperiled status, with important consequences for freshwater ecosystems and human well-being.
 “Trout and inland salmonids live in some of the highest quality cold-water habitats in the Northern Hemispheres. Unfortunately, we are systematically losing these places and the species they support. We need to identify and protect a network of these places as a heritage legacy for future generations,” says Dr. Jack Williams, Emeritus Senior Scientist for Trout Unlimited.
In addition, massive and wide-scale hatchery propagation and stocking not only have failed to reverse these global declines, but may very well be intensifying the declines by altering the capacity of local populations to adapt and overcome challenges from human-altered environments.Â
“Throughout the history of propagation and stocking, we’ve learned that we have become very good at producing fish. We are also pretty good at producing fisheries. But, hatcheries and stocking are not especially good at recovering or protecting ecosystems important for trout,” said John Epifanio, a US-based conservation geneticist.
Moreover, the emerging challenges resulting from global climate change is widely and rapidly altering temperature and precipitation regimes, greatly threatening those ecosystems occupied by native trout and their relatives.
Attendees at the Conference call upon the global community of scientists, anglers, governments, businesses, and civil-society to undertake a series of actions to address the root causes leading to imperilment of river ecosystems; and further, to avoid half-measures such as reliance on stocking of hatchery trout and the active transfer of species outside their native ranges. We join the broader scientific community of scientists calling on governments and societies to address the looming crises from global climate changes.
