Sustainable Phoenix Ponds

Saving natural habitats is hot on everyone’s mind these days. Riparian habitats are the rarest type of habitat in North America. The plants and micro-organisms found in riparian areas and natural wetlands are extremely efficient at removing excess nutrients from storm water and runoff. Unfortunately, man’s increased use of commercial fertilizers creates run-off extremely high in nutrients such as nitrogen and phosphorus, which poses a major threat to the delicate ecosystems of our natural waterways. As a result of this, as well as excess traffic and use, 95% of the West’s best filtering habitats have been degraded to at least some extent.
Phoenix Ponds with Wetlands Replenish Disappearing Natural Wetlands
What exactly makes a wetland such a good filter, even for a backyard pond? Wetlands are giant sponges. They protect ponds, lakes, rivers, streams, and aquifers by filtering out wastes and nutrients entering from storm water and runoff. Scientific studies have found that many common species of aquatic plants have the ability to uptake toxins directly from the water, thus scrubbing it clean again. This can even be accomplished in a backyard pond!
Thinking of aquatic plants as the kidneys of the earth, it follows then that a constructed wetland filter would be an excellent approach to cleaning up an existing problem pond, as well as an outstanding way ensure that a backyard pond has plenty of filtration from the start, while providing a lush, beautiful setting.
Wetlands are Nature's Filter
Clarity is one of the easiest and fastest ways to diagnose water quality in a backyard pond. Large loads of sediment and debris can have a serious impact on the aquatic life that a body of water can support. Wetlands, both in nature and constructed for backyard pond filtration, do a tremendous job of reducing sediment and debris, improving clarity within the pond. Natural wetlands are able to remove sediment by slowing the velocity of storm water, causing the sediment and debris to drop out of suspension. To see this concept in action, visit Regents of Scottsdale Apartment Complex, 15555 N. Frank Lloyd Wright Parkway, Scottsdale, Arizona. This riparian ecosystem that spans the center of the complex accepts runoff from the surrounding parking lots. Over the past six years of this system’s existence, the maintenance required has been quarterly bacteria and enzyme applications, along with monthly thinning of aquatic plants from within the streams
Phoenix Ponds Thrive with Wetlands!
A constructed wetland filter of proportionate size can help provide crystal clear water in almost any backyard pond. We’ve all seen the chemically treated, generally blue-dyed, bodies of water that adorn many golf courses, apartment complexes, and HOA common areas. Furthermore, backyard ponds with a lot of large fish require a filtration system sufficient to keep up with the wastes these fish produce.
On another note, many people have “green thumbs” and are attracted to the types of plants that can be grown in a backyard pond. Installing a wetland filter off to the side of a backyard pond will provide the perfect planting bed for a variety of aquatic plants, while allowing the garden owner to keep the pond surface area open for viewing.
Wildlife Appreciates Phoenix Ecosystem Ponds
In addition to being a superb filter system, placed appropriately, the permanent and accessible organic water in a backyard pond is a boon to birds, both native and migratory. 80% of desert wildlife lives within sight of a riparian corridor. However, we have been damming and pumping our riparian areas out of existence here in Arizona. Constructed wetlands, and organically maintained backyard ponds, may be the best bet for the survival of many species of native and migratory bird life. In terms of economics, Arizona is a top ten birding destination on every birder’s list, and birding is a $2.5 billion a year tourism industry. Arizona’s share of this money in is huge! Adding a constructed wetland filter to a backyard pond not only adds a truly “green” element in every sense of the word, but provides a safe oasis to native and migratory birds, whether in the open desert, on a golf course, or in someone’s back yard.
