Want to Save the World from your Backyard?

Thought you might.

Here’s how.

One word (sounds like two) : Hedgerows

Hedgerows are nature’s secret little multitool.

Our ancestors knew this and learned to use hedgerows to work with the land and craft their ideal landscape.

Historical uses of hedgerows range from insanely effective natural fencing to pointed targeted change of air currents. Once you’ve decided to use hedgerows in lieu of more mechanical landscape features, you have officially become a force of nature. It’s like having nature give you a big thumbs up as you change the landscape to meet your needs.

Why would you need a hedgerow though? What can hedgerows do for you that grass can’t?

First, Google, please define “emergent properties” :

“In philosophy, systems theory, science, and art, emergence is the condition of an entity having properties its parts do not have, due to interactions among the parts. Emergence plays a central role in theories of integrative levels and of complex systems.” - Wikipedia

Or, straight to it, emergent properties belong to a group of separate parts creating something together which none of them could create on its own. More importantly, there’s a special something to what the parts do as a group. An almost lifelike something, like what happens when a group of cells turn into a human, when the tomatoes tastes like the sun and the soil, when the satellites synchronize with the angular momentum of the Earth. This is when dreams become reality. And this is what we’re looking for when we approach anything in our landscapes.

The only way we can mediate our impact on nature is to work with it.

This is how we change the world.

Hedgerows hit the magic number in terms of ecological functions ; According to the Jadrniceks who authored The Bio-Integrated Farm, when a single component of the system fills at least 7 functions for the system, the system will produce the emergent property, and become resilient to most disturbances. Hedgerows, at minimum, fulfill 10 ecological functions by default.

  • Hedgerows change air currents - Hedgerows make warm spots cooler, block strong winds, and change the amount of sunlight reaching the soil. They alter the topography the air currents roll over through the landscapes, the same way rocks alter the currents in a flowing stream.  

Functions :

  1. Change air currents and dynamics

  2. Create and maintain microclimates / microhabitats

  3. Improve air quality (by the nature of plants)

  • Hedgerows provide food and harborage for beneficial wildlife. When hedgerows are intended for integrated pest management, they are designed to shelter and feed the predators of common plant pests all year long - meaning highly reduced amounts of insecticide use. With the insects come the rest of the food web and suddenly there’s a whole ecosystem in your backyard. With that hedgerows become a wildlife corridor:

“A wildlife corridor is a link of wildlife habitat, generally native vegetation, which joins two or more larger areas of similar wildlife habitat. Corridors are critical for the maintenance of ecological processes including allowing for the movement of animals and the continuation of viable populations.” - Environment.NSW.Gov

On the small scale that means bees and pollinators can move and feed freely from point A to point B with your hedgerow in between. On bigger scales the results are large animal migrations through the Back Forty (which can open up huge income opportunities for hunting permits on private lands and have huge implications for ethical meat sourcing).

Functions :

4. Insectaries for pest predators

5. Pollinator food source for native pollinators.

6. Reliable food and nutrient exchange throughout the food web.

7. Wildlife corridor for critters to get to point B with reduced mortality rates.

8. Introduce new nutrients to the system from migrating animals.

9. Increased biodiversity.

  • Hedgerows play a vital role in nutrient cycling. During periods of erosion, a hedgerow located down slope will act as a soil catchment basin, and will deposit the otherwise “lost” nutrients into their roots and shoots for further ecological use. Over time the hedgerow catchment basin will change the entire topography, eventually turning slopes into terraces.

When on a slope, hedgerows act as a filter strip for incoming and outgoing water, helping to keep streams clean and salmon safe.

Certain plants bioremediate the soil by uptaking soil toxins, and can later be harvest and sent in as “ore”.

11. Soil nutrient cycling

12. Soil Remediation

13. Water filtration

These are just the benefits to nature that come along with having a hedgerow, mostly regardless of what you want the hedgerow to do.

Now what you get from the hedgerow will vary depending on your priorities. What are you looking for in a hedgerow? Do you need a natural fence for your animals, or marked out property lines? Do you want to harvest from your hedgerows, get some plums and mulberries maybe? Maybe you’d like money from the government for your hedgerow, the grants are pretty easy to get.

Hedgerows are a powerful tool to affect change in a biological way, and molding nature to work within your lifestyle can be as simple as plugging in cuttings from the trees next door.

We at EZBFG and Landscapes believe that there’s a plant for every problem. If you want to know the hedgerow that’s right for you, go ahead and take our Mission Code Name : Hedgerow quiz below and see how nature can help you. So quickly! Do something the future you will thank you for!

From all of us hear at EZ BioFriendly Gardens and Landscapes, may the rain clean your lungs, the falling leaves be music to your ears, and the air crisp with fall.
