The two houses in these photos are located just a couple doors down from one another. Both houses are right on the beach. They literally have the beach in their backyards! The owners of the home in the top photo have a typical lawn. The owners of the home in the bottom photo chose to leave the existing trees and shrubs in place rather than clear the lot.

These houses front onto a busy highway. The house with the trees gets a free privacy buffer and noise buffer. Interestingly enough, although the lawn obviously has a much lower volume of vegetation, the lawn people probably have to water their yard more than the tree people do. The tree people might not have to water at all! (Actually this lawn doesn’t look too extremely green, like those you see sometimes whose uncannily green color is maintained by massive inputs of water and fertilizer and weed-killer. It looks fairly low-maintenance as lawns go. Still, the trees win hands-down in terms of beauty and functionality!)

Another benefit: The trees to the west shield the house from the fierce afternoon sun, which probably means the tree people don’t need to spend as much money to cool their house as the lawn people do.

Smart people, those tree folks! So much else to do with their time other than maintain a clipped lawn. After all, the beach beckons! … Or the library, or the fishing pier, or the art museum …

They may or may not realize it, but the tree people aren’t just benefiting personally from their landscaping choices; they are also helping to reduce the load on the stormwater infrastructure and protect the land from wind and water erosion. And they are creating a cool moist microclimate which provides habitat for beneficial wildlife as well as making life more comfortable for humans.

A fine example of stacking functions, as we say in permaculture design.

In my town (and possibly yours too), we’ve got a water crisis. Sometimes our stormwater infrastructure is overloaded by flooding. Other times we’ve got drought. Interesting how everywhere I’ve lived, from deserts to rainy subtropical areas, the situation seems to be pretty much the same, alternating between these extremes.

If that’s not bad enough, our waterways here in Florida are polluted by toxic bacteria and algae which is killing the wildlife and even in some places making it difficult for humans to breathe.

Some of the best solutions to our big water woes are the simplest.

One, conservation. Quite simply, use less water and encourage others by your positive example. When friends and neighbors hear how low your water bill is, or see your pretty yard that requires no fuss because it’s all locally adapted, hardy, drought-tolerant plants, they will take notice.

Two, harvest rainwater. Rainwater harvesting is not just cisterns; it’s also doing things that help the soil hold onto water longer, and help trees and other plants sustain themselves through periods without rain so they don’t need constant daily watering. Examples include mulching (fallen leaves aren’t trash; they’re treasure!); adding compost to the soil; planting (or allowing to remain in place) coastal grasses and shrubs that help reduce runoff from a site; creating berms and swales to do the same. And of course, rainwater collection does include rainbarrels too.

Three, composting. Keep your kitchen scraps out of your trash, and compost them. If you currently use a garbage disposal, you can save a lot of water by composting instead of throwing food down the drain. Food scraps aren’t trash; they’re treasure! Even apartment-dwellers can compost; there are many compact units on the market designed for indoor use.

And, very important, urge your local government to implement all of the above on a city-wide or county-wide level. Many cities have composting programs already. New York City is one! Here’s a municipal compost bin at my cousin’s apartment complex.

Ask your city to institute low-mow or no-mow landscaping practices, such as retaining a buffer of wild vegetation along all waterfront areas, and transitioning to a more natural mix of vegetation in road medians.

My city is on the verge of requesting the state to have its allotment of water increased. And we’re about to embark on a fancy and expensive wastewater-treatment experiment. Unless we first do a lot more in the way of conservation, this is outrageous, morally bankrupt really. We could probably cut our usage almost in half without breaking a sweat! The simplest thing is always to cut back and use less. Costs nothing, and can even put quite a bit of money in our wallets, not to mention creating a kinder and more beautiful world.

I leave you with one of my favorite quotes:

“Although the problems of the world are increasingly complex, the solutions remain embarrassingly simple.” — Bill Mollison

Trees in a forest grow in guilds, rather than in isolation. Oftentimes their branches end up encircling one another or even intertwined. Here in Florida, a common sight is a palm tree growing up into the branches of an oak. This beautiful duo in my neighborhood offer a nice visual metaphor for human interdependency also.

So did the palm tree nurse the baby oak seedling, or was the palm tree seedling nursed by the tall leafy oak? I imagine the latter, as the oak tree looks to be of a stately age, and palm trees don’t offer much shade. But it could have been a different scenario entirely. These trees sit on an empty, mostly grass lot which at one time was probably densely forested with a much wider variety of tree and shrub species.

While googling for an answer (I haven’t found one yet), I stumbled on this article, A Miami Emblem Is Sacrificed for Shade, about how the city of Miami realized it needed to start planting oak trees again. (Truly, there should be no sacrifice required; it should not be an either-or. The palm tree growing within the branches of the oak offers a memorable reminder.)

The article was published back in 2006 but it caught my eye because my city seems to be cutting down a lot of oak trees, as well as palmettos and other native scrub, from public lands, leaving little except wide expanses of buzzcut turf grass and palm trees. A lot of homeowners seem to be doing this as well. It makes for a rather desolate, not to mention hot and relentlessly sun-scoured, landscape.

Botanical Nursing: From deserts to shorelines, nurse effects are receiving renewed attention: paper in BioScience journal. Fascinating overview of the various aspects of botanical nursing, and how the benefits tend to be mutual rather than one-sided. Key takeaway: “One plant’s reliance on another for its survival and growth has clear implications for conservation: Namely, saving a species dependent on nurse plants requires saving the nurse plants and endangerment of a nurse species endangers plants that depend on it.” Something for cities (and homeowners) to keep in mind as they remove seemingly “extraneous” or “undesirable” vegetation. Also: “Just as nurse plants are important to preservation, they can also be useful in restoration. … [W]ork on denuded ski runs in the Swiss Alps has focused on creating ‘safety islands’ — patches of diverse vegetation that provide numerous sites in which seedlings can safely establish.”
