The Beauty of Blue Carbon

By Hilary Stevens

Coastal wetlands are a valuable component of our landscape for many reasons. They provide habitat to many species that are important for fisheries and recreation. They reduce wave energy and help mitigate coastal flooding.  It turns out that they also help control the rise of greenhouse gases in the atmosphere by trapping carbon dioxide in plants and in soils.

Climate Change and Invasive Species

By Carrie Brown-Lima

Invasive species are on the rise as trade and travel accelerate the introduction and spread of new species in a way never seen before. Simultaneously, our climate is changing at an unprecedented rate resulting in climate extremes. While these two phenomena are each daunting challenge to biodiversity, their impacts can act synergistically and present additional hurdles for conservation and sustainability.

The Four Laws of Ecology

By Barry Draycott

Last year I found a copy of The Closing Circle, Nature, Man & Technology by ecologist Barry Commoner. I started rereading it and was stunned to find in the first chapter, even before he states the Four Laws of Ecology, Commoner discusses the fundamental interaction of nutrients, humus, soil microbes, plant health, and climate! What is amazing is the book was published in 1971!!

Tools to Help Landscape Professionals Tackle Climate Change: An Ongoing Challenge

by Amanda Sloan

Many landscape professionals realize they are in a unique position both to notice changes to the local environment resulting from greenhouse gas emissions and to propose and enact creative solutions to counteract those changes. In 2018, ELA began discussion at the board level about what kinds of practical tools could be developed and promulgated to help landscape professionals transition to methods that do not cause greenhouse gas emissions. Subsequently, the ELA’s Carbon Working Group was formed and is looking for input.

Managing Forests as a Natural Climate Solution: Understanding the Contributions of Heterogeneous Landscapes

by Ian A. Smith and Lucy R. Hutyra Constraining the global average temperature rise to below the targeted 2°C (3.6°F) will require both a reduction in greenhouse gas emission rates and natural climate solutions through land stewardship practices that remove greenhouse gases from the atmosphere (1). Forest management is at the heart of many natural…

Keep Carbon in the Ground

A Scientific Exploration of Climate Change and Soil Health by Dr. Kristen DeAngelis Soils rich in carbon are healthy soils, but climate change and poor management practices threaten to degrade soil carbon stores and in turn, degrade soils. In this article, I’ll present a brief overview of the current scientific understanding of why keeping carbon…
