We're losing our forests

Mature & old-growth forests in the Pacific Northwest capture and store more carbon than the Amazon rainforest.

They also support an amazing diversity of unique plant and animal species and provide important ecological services like water purification, climate regulation and flood and erosion control.

These same forests are under increasing threat from climate change, urban sprawl and public & private logging practices.

Resource use needs to be balanced with conservation, and everyone needs to be involved in holding our decision-makers accountable.

What does the research say?

We fund a number of researchers at Oregon State University and the University of Oregon who are looking at mature and old-growth forests as natural climate solutions through the lens of biodiversity, air and water quality, fire ecology and carbon storage. They are clear; preserving large tracts of mature and old-growth forests is critical in the battle against climate change and biodiversity loss.

This has profound implications on long-term forest management and we need to make our federal and state representatives are acting in the interest of current and future generations.

What we're doing

Worthy Environmental is working to document the complicated value of mature trees with the goal of changing how they are managed in natural and urban ecosystems. Through supporting research in carbon storage, climate change, biodiversity values and habitat quality, we're helping quantify the benefits that mature trees have for people and the planet.

We also interpret the findings of these studies for the general public and our legislators. The disconnect between academia and these two groups often results in misguided laws and public confusion. Making this information accessible is critical to creating change.

Become educated on the issues happening in your own community, state, region, country or world.

Contact your local representatives and express your feelings about forest health, global climate change and the effect of logging on our public and private lands.

Support efforts to plant trees and other vegetation to regenerate some of the ecological functions lost through logging, ranching and other "management" activities.

Support our work through donations, volunteering and shared SOCIAL MEDIA posts.
