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 Reduce the Ecological Footprint of Wind Turbines

Wind power is the second most widely used renewable energy source in the U.S., just behind hydropower. Unlike solar, wind power creates little to no pollution and requires very little maintenance. However, it has one significant problem — a detrimental effect on wildlife and the local ecosystem.

Industrial wind farms wreak havoc on bird and bat populations, plus they pose an ecological disturbance to the land. While the energy generation is incredibly sustainable, the influence turbines have on local wildlife populations adds controversy to the success of this energy source.

The future implementation of wind as a leading source of energy will depend on our ability to reduce its ecological footprint. Employing best practices that work to minimize adverse effects on local habitats will play an integral role in the construction of new farms.

Analyze Data

Determining the exact impact of wind turbines on wildlife is hard to discern. The number of birds and bats killed from direct contact is only one variable. The long-term effects on food chain supplies, population and habitats are hard to quantify. The first step in reducing the environmental impact is determining where the influence is greatest.

Research estimates that in North America alone, wind turbines kill an estimated 140,000 to 328,000 birds each year. This statistic does include other flying creatures, like bats, whose populations have been significantly affected by wind farms.

Bats are essential to the function of our ecosystem and food system. In 2015, the American Wind Energy Association (AWEA) added guidelines about the voluntary process of halting turbines at lower speeds during periods of the night when these animals are most active. These efforts may reduce deaths by up to 30%, though research demonstrates an extra delay could potentially increase that number to 90%.

Land Use Planning

Close attention to site selection and preparation may curtail the consequences of wind farms on the surrounding environment. Construction is a major ecosystem disruptor, as installing transmission lines and removing soil can hurt plants and animals in the vicinity. Experts encourage many wind companies to engage in erosion control practices, which includes re-establishing native vegetation and other restoration techniques.

Wind farms are generally criticized by their inflexibility when it comes to site location. Compared to solar panels, which can be installed on buildings and utilized across a diverse array of environments, wind farms are more limited. One benefit, however, is that people can establish these turbines on abandoned industrial land. The ability to re-purpose previously degraded land with a renewable energy source is a victory for wildlife and humans alike.

If the wind is too strong, wind turbines can’t operate safely and must shut down.

A final consideration when it comes to reducing ecological impact includes preventative measures, such as monitoring a habitat before construction. By tracking the environment before breaking ground, builders can better determine the best location for the farm.

Innovative Technology

As wind power becomes a cost-effective and energy-efficient option, advanced technology will lessen the impact of turbines on wildlife. According to U.S Energy Information Administration, the wind industry is collaborating with the U.S government to find optimization solutions.

Several ways exist in which wind farms can reduce their impact on local habitats and take preventative steps affecting animal and bird populations. One example includes Ultrasonic Acoustic Deterrents (UADs), which emit a loud noise that deters bats but is incomprehensible to the human ear.

Other solutions include painting wind turbines purple or shining ultraviolet lights on the structures to alert migratory species. Some manufacturing companies plan to make innovations in how to construct these structures. Changes include alterations to the blade surfaces and more sound-absorbent materials.

A Comprehensive Approach

The cost of wind power has dropped almost 50% in the last four years. With an increased incentive to invest in renewables, experts predict the number of wind farms around the world to grow rapidly in the next decade.

Wind power has many benefits, one of which being that, unlike solar, return on investment for the production and installation of turbines is five to eight months, with each structure designed to produce for at least twenty years. With an increase in implementation, the ecological impact is unavoidable. As a result, the focus will be on reducing the footprint of wind turbines, rather than decreasing their utilization as an energy source.
