Garden Mulch Helps Waterways

Posted on by .

Garden Mulch Helps Waterways if enough people use it. Much of the dirt in our waterways is due to storm water picking up chemicals and debris. Many of these items result in damage to rivers, streams,catchments and oceans. We sense that this causes pollution and depletes marine life, and we see it clearly in times of flood, but it only takes a shower.

 When it is raining heavily, rainwater flows over the lawns and gardens picking up debris,pesticides, fertilizers, oil and many other harmful substances. These are subsequently dumped into the streams, bays and rivers. Read more

Storm water poses a serious challenge to many communities. Unchecked, it will run off from your roof or the driveway and onto the streets. From there it moves into the drainage system and finally into the waterways. Rain Gardens can help.

In principal there is nothing wrong with how municipal storm water systems are intended to work. However, as the water flows over the various surfaces, it picks up a lot of litter and chemicals. These also end up in the lakes, rivers and streams where they can cause serious harm to biodiversity. Another big problem with Storm water, is that it is extremely powerful. Read more

Can frogs measure water healthCan frogs measure water health?  According to National Geographic the answer is Yes.

Frogs act as biosensors and help us in detecting polluted water

Frogs produce an unmistakable croaking sound that is associated with their mating behavior. There is a natural frog croaking sound that occurs when the environment, (water), is not affected by any toxins. However, scientists have discovered that this sound changes according to the level of pollution in the river. So clearly in their own way frogs measure water health.

How environmental factors impact the croaking of the frog

The condition of our lakes and rivers, especially close to population centers, is often impacted by a variety of factors. There is often industrial effluent  released into the river Added to this is a large amount of human waste that finds it’s into the water ecosystem. A lot of the substances in the water are going to affect the hormonal balance of animals. Not only humans using the ecosystem but also of the aquatic life such as frogs. In fact the effect is particularly pronounced on the smaller animals. Read more

Hunting Fish on WaterAccording to Wikipedia Hydrobiology is “The science of life, and life processes in Water”

Part of the broader studies of our Ecology, Hydrobiology looks at the the health of living , water based organisms in both flowing and still water, and includes studies in Economic Biology, morphology, taxonomy,Industrial Biology and others.

For us the significant feature is that all these studies focus on the health of the aquatic creatures, which in turn rely on the health of the water itself.  This study ties in closely with both sewerage management and water purification, as well as management of Rivers, Lakes water catchments etc Read more
