Essay On Deforestation And Reforestation

[Liliane Hubright]

Deforestationrefers to the removal of forest or stands of trees. The trees may be used for construction, or wood and paper, or they may simply be removed so that the land can be used for other purposes, including agricultural activities or urbanization. Reforestation is the growth of new forests, either without human influence by simply restricting human activity, or by the human re-planting of trees. Humans have engaged in deforestation for thousands of years, but industrialization over the last 300 years, and especially over the last 70 years, has led to extensive deforestation. In some parts of the world land use change has also led to substantial reforestation.

Reforestation is the act of restoring trees in an area where their population has been reduced due to either natural causes or human intervention. Reforestation after a wildfire by intentionally planting new trees or encouraging the natural recovery of degraded forests are just some examples of reforestation.

The best reforestation practices recommend immediate planting once a forest is cut down or destroyed. Thus, tree-felling companies are to restore the balance by planting new trees after logging, according to governmental regulations in many countries.

The UN New York Declaration of 2014 obliged countries to reduce deforestation twice by 2020 and halt it by 2030 What is the New York Declaration on Forests? Forest Declaration Platform.. However, its annual rate almost doubled instead.

It takes around 10 years for soil richness to return after deforestation and 25 years for the whole structure and function of forests to be restored. However, it usually takes 120 years for biodiversity to fully recover. Benefits Of Reforestation Ecosystems can better withstand future stresses from things like climate change and wildfires when they have been reforested. The most significant benefits that can be gained via reforestation are as follows.

Photosynthesis explains another advantage of reforestation since plants not only absorb carbon but also release oxygen, maintaining the balance. For this reason, forests are known as the lungs of our planet. Correspondingly, the more forests we have, the purer the air we breathe. Also, reforestation is efficient in preventing dust storms, adding to air purity.

Woods fascinate with their ecosystem variety, and one of the richest communities is found in tropical forests. In particular, Amazon rainforests count thousands of tree species and 50,000 other plants, apart from abundant fauna.

The World Resources Institute ranked tropical primary forest losses in 2019 as the third-largest in the 21st century Weisse, M., Goldman, E. (2020, June 2). We Lost a Football Pitch of Primary Rainforest Every 6 Seconds in 2019. World Resources Institute.. In this regard, rainforest restoration is an ultimately significant task nowadays. It combats rare species extinction, both in the kingdom of plants and the kingdom of animals.

Trees store rainwater by absorbing it with their leaves and roots. At the same time, they also release moisture into the atmosphere via transpiration and increase humidity. This way, forests stabilize the air temperature in the nearby locality. They also help to maintain sufficient water levels in local water bodies. Since trees retain moisture and reduce runoff, reforestation also improves water quality and infiltration.

Trees not only absorb moisture but also make a barrier for water flow during floods or downpours. Thus, they slow down the speed of currents and improve water absorption. By impeding floods, reforestation mitigates damage and losses.

Planting takes place in two ways: either naturally or artificially. The natural reforestation process relies on the rooting of seeds and sprouts from nearby trees without human assistance. Yet, natural reforestation is insufficient and should be supported by other techniques when tree replacement involves the participation of people.

Reforestation is a routine operation for designated forest farms. Their optimal approach combines reforestation and deforestation when forests are cut in a way that helps establish new ones. The idea is to turn the end into the beginning whenever possible.

Both of them are used throughout the USA. The choice depends on whether the species can grow in shelter or not and the climatic peculiarities of the region. This is how deforestation gives rise to new tree stands when the remaining mature trees promote new generations. They provide seeds, wildlife habitat, shelter from excessive sunlight or wind, etc.

The area size in group cuts differs by width and can reach two heights of mature trees. The width depends on the amount of light the species requires. Spruce, fir, maple, hemlock, and red cedar can tolerate shade and will do with a smaller opening. Oaks, loblolly pine, and Douglas fir need more light and, correspondingly, more space. The group selection covers the whole forest tract.

The single-tree reforestation technique chooses separate trees of all sizes and cuts them evenly through the patch. Since the opening is too narrow, the method is suitable only for shade-tolerant species (e.g., hemlock, sugar maple). It also applies to frosty or dry areas.

Clear-cutting is the complete removal of mature overstory trees to let new trees grow. However, some trees may be preserved as shelter for wildlife or riparian buffers. This is a popular reforestation method to regenerate aspen, yellow poplar, white birch, Douglas fir, red and white oak, jack pine, etc.

This practice extends beyond the mere selection of tree species and delves into the realm of environmental ethics. While considering which tree species to plant, one inevitably ponders the underlying purpose of the reforestation efforts. For preserving biological diversity, it is important to use local, native species and ensure that your reforestation strategies are in line with the local ecosystem.

The faster rate of decomposition seen in non-native plants compared to native ones often results in increased CO2 emissions. This shows how important it is to pick the right tree species. Any business serious about reducing its carbon footprint should conduct a study of tree species suitable for the local environment and plant only them.

Newly planted trees absorb almost no carbon. So, the beneficial impact of reforestation on the environment, such as lower carbon dioxide levels in the air, may not be seen for 20 to 30 years. Here, the strategy of reducing the deforestation of older trees, which absorb far more carbon dioxide, overcomes the program of replanting. However, given the current state of affairs and the actual consequences of deforestation, the optimum course of action is a mix of anti-deforestation efforts and intentional reforestation.

Positive reforestation effects are more obvious with proper forest management. So, first, it is important to develop a reforestation plan depending on your purpose (restoration after illegal deforestation, harvesting, wildfires, etc.). With different reforestation purposes, the best trees for planting will be different, too. There is no universal answer to which species to choose since some are the most carbon-absorbing while others are the fastest-growing.

Another discussion point is whether or not reforestation can restore the ecosystem of the previous forest. Here, it depends on the species again. A single tree type will create a monoculture forest, while multiple species will enhance biodiversity. Monoculture forests are more susceptible to tree diseases and other unfavorable conditions, while polyculture forests have more chances to survive. Besides, clear cuts or prescribed fires prove to be an efficient means to speed up natural restoration and ecosystem diversification.

Reforestation management and monitoring are easier with remote sensing, especially in hard-to-reach places. With the satellite-based EOSDA Forest Monitoring solution, you can monitor reforestation progress, receive timely notice if things go wrong, and react accordingly. Low- and medium-resolution remote sensing can detect the changes after 1-2 years of tree planting, while high-resolution remote sensing can provide information much earlier.

EOSDA Forest Monitoring uses satellite-based vegetation indices to track the condition of newly planted forests. It helps locate regions with unhealthy canopies, allowing foresters to take prompt corrective action to preserve tree life there.

The NDMI index serves to assess the level of water stress. This indicator can be used to determine if there is a shortage or an abundance of water. Leveraging processed satellite images from EOSDA Forest Monitoring, forest managers can examine expansive forest areas and pinpoint trouble spots for developing more targeted tree protection strategies.

Using satellite imagery, our technology can pinpoint the exact location of reforestation inside a specific area of interest (AOI) or across any larger area. We have the technological know-how and the satellites (both free and for a price) to detect reforestation, including the Sentinel-2 optical satellite, the Sentinel-1 radar satellite, and our very own EOS SAT-1, to accommodate any budget.

The importance of reforestation is explained by the role trees play on our planet. New forests help prevent soil erosion or desertification; they are important to protect buildings and fields from winds. Trees along river banks or shorelines fortify and stabilize the coastal area. Woods are natural habitats for unique species that, in some cases, cannot be found anywhere else. This is why it is important not only to regenerate the degraded or destroyed areas but also to plant new ones to refresh the tree cover.
