COVID’s Pendulum
By Trevor Smith
Goodbye 2020 and good riddance!!! Though we are not out of the woods yet, I couldn’t help but feel a weight lifted as the ball fell at the stroke of midnight. 2020 started like any other year, with hope and possibility. The anticipation of a new season combined with knowing how crazy things would be in spring felt like I was on a rollercoaster about to hit that big drop. All I could do was hold on as the world rushed past. Little did we know that drop would be less like a rollercoaster and more akin to Niagara Falls.
Update: Plastic Pots Used in the Green Industry
By Marie Chieppo
In 2019, the Association of Professional Landscape Designers (APLD) sustainability committee asked me to research and write about plastic horticultural pots use and disposal methods. Because plastic is so easy to use, billions of plastic pots were being produced without a blueprint for what would happen as demand increased. Unfortunately, we’ve produced so much plastic that we can’t possibly recycle it all.
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!!
Five Things I Learned This Year
By Cathy Weston
Back in my professional working days, I relished the quiet time around the holidays. I went into the office and used the time to clean and organize files, make a priority list of the next year’s goals, and start my year-end review. Now, as an ecological gardener, I do something similar. I develop next year’s planting projects and reflect on what I have learned on the journey to ecological gardening.

Mitigating the Effects of Climate Change On Grassland Butterflies
By Angela Laws
Declining biodiversity has been making its way into the news more and more as researchers continue to record losses in plant and animal populations. Insects are no exception, and several recent studies that use long-term data sets show a marked reduction in insect abundance. A variety of factors contribute to these insect declines, including the loss of habitat, pesticides, invasive species, and, increasingly, climate change.
Green Stormwater Infrastructure
By Anna Shipp
Our current economic downturn caused by COVID-19 and ongoing social and climate crisis demands a transformational change in everything from business practices to public policy, including how we approach stormwater management. In rebuilding our economy, the government must prioritize green stormwater infrastructure because it’s a tool that fosters job growth, public health, community well-being, and resiliency.
