What is Revegetation and Why is it Important?

Revegetation is a vital step in facilitating a successful soil restoration in disturbed lands. It can occur naturally through plant succession and colonization or accelerated human-driven land changes meant to repair damage caused by severe events like floods, wildfire, or mining. The original technique involved applying fertilizer and seeds to vulnerable lands.

For those unfamiliar with revegetation, you’ll want to review its benefits to prevent soil erosion successfully, reduce wind erosion, and boost soil’s ability to soak up water that runs off the surface. Without employing revegetation-based erosion control strategies, plant communities and delicate habitats may sustain avoidable damage.

Benefits of revegetation

Unlike the normal tree planting process, revegetation requires pre-planning activities like land designing. In the designing phase, you’ll outline which type of plants to use in specific areas and perform soil compatibility studies. Proper environmental and landscape analysis are the key to successful revegetation. Proper planning ensures that you allocate money and resources wisely and fare a better chance of achieving your goals and earning a profit.

Some native plants can only grow in specific areas, so it’s essential to identify which plant types can endure your region’s climate. Homeowners complete the revegetation process for various reasons, including its ability to benefit governments, private individuals, communities, and companies, alike.

Soil erosion control

Revegetation is crucial, as the risk of erosion damage increases when the land is bare or contains little vegetation cover. Plants offer a protective barrier and prevent soil erosion by slowing down water runoff and encouraging more water to seep into the ground. Additionally, the roots hold the soil intact while protecting the plant itself from powerful rushing water that can wash it away. This plant life also assists in stabilizing slopes and embankments, lowering the terrain’s susceptibility to landslides.

Trees, grass, crop residue, and plants offer ultimate soil coverage and intercept all falling raindrops, acting as the most effective soil erosion control measure. Mulch provides additional protection from wind and rain before the newly-planted seeds take root while minimizing soil moisture loss during prolonged dry periods.

Mulching is crucial in halting destructive erosion and establishing vegetation in places with severe exposure to natural and human-driven erosion. Experts advise utilizing hydromulching in such conditions. The absence of windbreakers like crop residue, trees, and shrubs leads to more soil displacement, thus increasing erosion and abrasion.

Conservation

One of the primary roles of revegetation is to connect lost patches of natural habitat. It serves as a crucial tool in areas that have suffered extensive natural vegetation clearances like urban environments. Research shows that revegetation can facilitate the restoration of significant urban bird populations by connecting the existing habitat with new patches, enhancing bird species diversity.

Developing large habitat patches is an effective method of increasing bird abundance. Therefore, revegetation plans should carefully consider how to connect the new vegetation patches with the existing habitats for the sanctity of bird populations. Revegetating agricultural zones, in specific, can encourage breeding.

For the most part, revegetation favors thriving and common species of birds over declining, rare types. Despite its favoritism, revegetation provides a home to millions of species like small mammals, insects, and birds, when successful.

Soil fertility restoration

Activities like mining lead to extensive topsoil damages as reinstatement, stripping, and stockpiling causes soil degradation. This damage occurs through accelerated soil erosion, soil structure loss, soil PH reduction, organic matter depletion, compaction, reduced microbial activity, and heavy metal accumulation. Topsoil management is essential for restoring fertility and minimizing nutrient losses.

Revegetation via forest vegetation restores soil fertility by improving the capacity to exchange cations, organic matter, and available nutrients while sustaining biological activities and improving physical conditions.

This method is beneficial, but it takes prolonged periods to regenerate the soil to its original state. Some of the ideal trees for revegetating mined lands are grasses, legumes, trees, and herbs N-fixing species. The favorable tree species are Leucaena, Acacia, and other acid-tolerant legume trees, which provide the soils with substantial organic matter.

Pollution reduction

Revegetation and reforestation play a significant role in minimizing pollution. The net carbon release from deforestation was estimated at 1-2 billion tonnes in 1980 and between 1.5- 3 billion in 1989. There’s enough evidence to verify a significant increase in deforestation since 1980 in multiple tropical areas. Revegetation offers a long term solution to sequestering carbon (IV) oxide because as trees mature, they eliminate Carbon (IV) oxide, thus slowing down carbon buildup in the atmosphere.

Beautifies the landscape

Besides purifying the air by filtering pollutants and harmful dust and gifting human beings with life-supporting oxygen, vegetation also makes the environment beautiful. Revegetating bare land makes it attractive, restores its appearance, and can even boost its value.

If you notice your yard is looking dull or lifeless, vegetation can add color to a property’s outdoor living spaces. For example, trees bear beautiful flowers, magnificent leaves, and fruits, which can sprinkle vibrant accent colors throughout your back and front yard.

It would be best to seek an expert before embarking on your revegetation project, as it can be a meticulous process. A revegetation expert will offer expert insight and advice on how to proceed.

How to Improve the Quality of Your Soil

Soil is important, whether you’re growing prize winning roses, landscape shrubs or your own fruit trees. All need to be in the right type of soil to get the nutrient they need. Even beginners can improve the quality of the soil in the garden. All you need to do is follow these simple steps:

  1. Add Compost

Compost is not just for preparing the beds in the spring. Compost can be placed into your raised beds in the fall and improve their conditions over the winter. Because they will be sitting over the beds all winter, this doesn’t even have to be completely broken down compost either. A lot of the process will happen right there on the bed.

You can even use this method as a practical way of getting rid of all the waste you pick up from your garden in the fall. Just spread this over the bed and cover with mulch. The mulch protects the soil and the nutrients in the compost.

  1. Use Soil Amendments

Different soil amendments can be added to your soil to make it more suitable to your purposes. Choosing which soil amendment to use with your sol will be a matter of matching the proper solution to the problem you are facing. For example, there are amendment for increasing the nutritional content of your soil and others for improving the soil’s texture also known as tilth. For example, if your notice that the water is draining away too fast, you can add an amendment that allows you to soak up the moisture and the reverse is also true.

You can adjust the conditions of the soil to your exact needs with the right soil amendment. This could be compost or other rich matter that absorbs moisture or an amendment like greensand that allows water to drain away more easily.

Here are some common soil amendments that you can consider using for your garden as needed:

  • vermiculite (worm castings)
  • compost
  • greensand (or green sand)
  • grass clippings
  • cornmeal
  • alfalfa meal
  • straw
  • kelp meal
  1. Plant a Cover Crop

When you are thinking about improving soil quality, don’t forget the power of cover crops. This is not just an idea for large scale agricultural weed suppression. They are also a major benefit for backyard gardeners as well.

Cover crops are especially good for treating the soil as they provide oxygenation and improved nutrient availability. Alfalfa with its very deep root system pulls nutrients upwards from the lower levels of soil and make these more available in planting season. Then a couple weeks before you begin planting, this cover crop will be tilled back into the soil, increasing its organic composition and nutrient content.

This can also be used to improve the levels of nitrogen in the soil when using legumes as a cover crop. Fava beans, crimson clover and alfalfa are all good examples of nitrogen high crop covers. If you will not be growing anything particular over the growing season, you may consider a cover crop that protect and aerate your beds. (Pro tip: cherry trees are a great choice for the beginner backyard orchardist and benefit greatly from good soil).

  1. Try Lasagna Gardening

Also called sheet composting or “No-Till” gardening is another good way to improve your gardens soil quality and a perfect way to begin your raised beds and continue them. As you notice the quality levels of soil in your bed begin dropping down, you will keep adding new layers like lasagna which begins improving the quality of your soil from the top to the bottom. After the end of each growing season new layers are added.

For more information about your garden and the process of sheet composting, check out this article on the lasagna gardening method beginner’s guide. But there is one thing you will need to consider when using the lasagna method of composting. If you will be renovating your raised beds with the sheet composting method, you will need to wait a full 6-months before planting as you will need them to fully break down.

So this method will be best suited to those garden working with rotating beds or those gardeners who only plant one season. The following link included here will give some pointers on how this can be changed about and planting can be done sooner. Basically, if you would like to begin planting sooner, you will need to spread out a layer of compost and or healthy topsoil –– roughly 2 or 3 inches thick. You can then begin planting directly through this top layer.

  1. Prepare Raised Beds for the Winter

Never forget the importance of using the end of the year garden season is your opportunity to improve the quality of your soil in a number of ways. This end of the year ritual is like “closing down the shop” till spring. But, if you live in a warmer area of the country this might not even be necessary.

Here are some things to do. First, cut the plants as opposed to pulling them from the soil. Cutting the plant will allow the roots to rot away and this will make your soil lighter and airy. Then you can spread some compost out on the soil and cover this with a layer of mulch, the compost will be feeding nutrients back to the soil while the mulch will protect the soil and keep the nutrients bound in.

You can also just plant a cover crop and call it a year. Be sure to check out our article on winter gardening for some more things to do in the cold months.

Top 5 Sustainable Gardening Ideas

There’s no question that there is quite a bit of buzz around organic and sustainable gardening along with permaculture. Everyone wants access to safe veggies, fruits and even eggs, which means that many of the older “Victorian” style practices of gardening and keeping animals and poultry are really making a comeback. There are more and more people practicing urban agriculture in backyards and vacant lots across the country.

If you are interested in joining this group of eco-conscious individuals, then be sure to implement the top sustainable gardening ideas found here.

1. Reduce the Size of Your Lawn

Rather than having your entire property covered in grass and plants, consider adding more hardscape fixtures as time passes. As you do this, you can minimize the upkeep, water, and other maintenance that your lawn needs. It will also minimize the tools that you need to care for your garden and make the use of smaller, more green hand tools, like the ones at Easy Digging, a viable option when it comes to caring for your lawn.

2. Gather Water On-Site

In the past, people would say that “rainwater does magic on plants.” This is a phrase that has some truth to it. There is nothing quite as effective as rainwater when it comes to encouraging your garden to grow. Rather than letting the water runoff your property before it can soak in, why not gather some and use it for your plants. This is a great way to reduce the amount of water that you have to use from public or drilled sources, thus helping with water conservation.

3. Create a Compost Pile

You can create your own compost pile by using non-meat kitchen scraps and other plant materials. When done properly, you can create rich black soil. Rather than putting grass clippings and leaves in your garbage, add them to your compost, too. If you don’t want to start this from scratch, you can purchase a “starter” compost pile and then add to it.

4. Mulch with the Materials You Have Available

You can mulch with the materials that are readily available to you, such as wood chips, pine needles, and leaves. These are going to help keep the soil moist while enriching it and minimizing the presence of weeds. Avoid using cypress much because this is usually made from grinding and harvesting younger trees which is not a sustainable gardening method.

5. Use Native Plants

Only use the plants that are native to your area. This is going to help ensure they can grow with little intervention from you.

Are You Using Sustainable Gardening Practices?

As you can see, there are several ways you can make your gardening efforts more sustainable and more eco-friendly. Consider implementing the tips here and see how your property can flourish while you are still doing something good for the planet. It’s a win-win situation that will help you save time, money, and effort while still having a beautiful lawn.
