Drones used to repopulate forests

A recent strategy to repopulate forests uses drones to plant seeds at a safer and faster way than humans can. In different parts of the world, organisations are using drones to restore forests damaged by wildfires and other consequences of climate change.

This short video summaries what is taking place in the United States and the process which takes place. This company’s website gives a more detailed look into how they operate.

In the UK, organisations are using drone planting techniques in order to solve the issue of Ash dieback. Ash dieback is common in most parts of Europe and is a fungal disease which often spreads from tree to tree. Therefore, the seed spreading drone program aims to help repopulate forests with healthier trees.

One UK tech company, Dendra, is aiming to plant 500 billion trees by 2060. This idea could help restore forests which are being lost to deforestation due to organisations profiteering from the newly cleared land, for example the destruction of the Amazon rainforest.

In Myanmar people are tweaking the technology to plant mangrove trees along coastal areas and places hard to reach on foot. This new innovative design looks promising as not only are the drones used to plant trees at much higher rates and in places hard to reach, they are also used to help scan sections of woodland and provide information on specific areas of forests.

Deforestation: causes, impacts and solutions

‘In 2015, an estimated 50 percent of the planet’s wild forests had gone. And the destruction of forests has continued since. If the trend is not stopped, we will only have 10 percent of the world’s original forests left by 2030’ ­www.theworldcounts.com

A private corporation or government may want to deforest an area for agriculture, grazing or urban development. It is mostly a concern with countries in tropical regions like Brazil or Indonesia where rainforests rich in biodiversity are being lost at a rapid rate. Before looking at the causes of deforestation, it is important to distinguish between the agents and the causes:


‘The agents of deforestation are those slash and burn farmers, commercial farmers, ranchers, loggers, firewood collectors, infra-structure developers and others who are cutting down the forests. Causes of deforestation are the forces that motivate the agents to clear the forests’Deforestation: Causes, Effects and Control Strategies

To go in to detail about each cause would make this post several pages long, therefore I will provide a list of direct causes which can be looked at by following the link provided.


Some of the direct causes of deforestation (as referenced on page 7 in the article) are:

  • Expansion of farm land
  • Timber plantations
  • Logging
  • Overgrazing
  • Fires
  • Mining
  • Urbanisation
  • Air pollution
  • War
  • Tourism

In relation to the direct causes, this demonstrates that deforestation can be caused for various reasons in many different ways. However, the impacts this can have on local communities and internationally is mostly concerning.

The impact of deforestation increases global warming which has a collateral impact on the Earth and all its inhabitants.


‘Forests have a big influence on rainfall patterns, water and soil quality and flood prevention too. Millions of people rely directly on forests as their home or for making a living. But the risks from deforestation go even wider. Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming’WWF

Not to mention the vast amount of habitat and species loss to many plant and animals which are exclusive to certain rainforests and ecosystems which are then destroyed.


Therefore, when looking into solutions to deforestation there are many different approaches corporations or nations can adopt. Greenpeace offer an array of different solutions such as:

⦁ Corporations operating with ‘zero deforestation’ policies

⦁ Supporting Indigenous communities

⦁ Promoting sustainable lifestyle

⦁ Changing the politics

In summary, we must remember that when thinking about ways to solve deforestation it will often entail a multilateral solution. As it has already been established that:


‘Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation’www.earthobservatory.nasa.gov


Therefore, it is evident that there needs to be more cooperation with nations like Indonesia or Brazil, as they have some of the largest rainforests, to prevent the increase rate of illegal deforestation and rapid decline in forest and species loss.

Sustainable forest management and adaptation to climate change

Sustainable forest management can be defined as ‘outcomes that are socially just, ecologically sound and economically viable – the three pillars of sustainability‘. Each pillar is needed in order for a forests to thrive, if one of these pillars is missing a forest cannot be protected.

Depending on the type of forest that is being managed, such as a rainforest or a boreal forest, the management of that forest will vary. Management needs to be specific to the type of ecosystem that the forest resides, tailor to the legal framework and socio-cultural aspects depending on what nation the forest is found in. Although, there are objective requirements that all forests should include.

Climate change can present many uncertainties when managing forests, therefore a forest should be adapting to promote resilience against the threat of droughts, damage from pests, diseases and wild fire. One way this can be achieved is by practicing silviculture, which consists of controlling the structure and dynamics of a forest. In managing a forest one needs to take an adaptive approach as the climate is constantly changing. Additionally, aside from climate change other influences may include timber prices, land use change and recreational use. There are often extreme conditions one may have to plan for as well, such as extreme drought or rainfall, these are conditions that may need individual and adaptive plans for these issues.

‘Adaptive management is an iterative process in which it is important to test new systems and ideas and judge how these perform under extreme climatic conditions’ – Climate change: impacts and adaptation in England’s woodlands

It is important to focus on why and how a forest needs to be managed but also on the adaptive measures that need to be facilitated in order to prevent these issues from destroying forests.

Current research suggest that the adaptation of forests must be tailored to local communities. This is important as adaptations strategies vary among geographical location and the type of forest present.

Some strategies involve planting drought-resistant trees to provide food security and reduce erosion. Other strategies invest in forest genetic research and breeding programmes. This improves forestry growth rates and resilience to disease. Alternatively, focusing on restoring biodiversity can increase the resilience of an ecosystem and restore habitat loss.

Local adaptation methods may involve maintaining the quality of water surrounding a forest. In dry regions, sourcing scarce water sources can help maintain a forest by providing healthy sustenance. Another local strategy may be encouraging the increase of rare species of a certain tree to make the population more abundant. This can help particularly if that certain species is a valuable asset to the local community. However, local strategies has its limitations as local information is rarely documented and often preserved for a few members of the community. Also, a globalised market can impact the infrastructure of a local self-sufficient rural community.

In summary, adapting forests for climate change cannot be solved with one over-arching solution. Each forest, depending on region, will need to have specific adaptation strategies specific to that region. As climate change is a complex issue with unpredictable outcomes, adapting for a worst case scenario may be as complex as the issue itself. Therefore, in order to enable sustainable strategies which maintain the health of a forest, it is important to plan and put systems in place to better enable these adaptive strategies.

The forefront of climate change research

Disclaimer: I am in no way sponsored or endorsed by any of these organisations, I am just trying to spread the awareness of information on climate change.

Recent research on climate change taken from credible sources outline what current research is focused on. Some studies I have already written about in my previous posts so they will not be included within this thread. The aim of this is to give people an idea of what direction climate change research is currently heading:

Side note: an interesting podcast mini-series from the University of Oxford on climate change and its research models, economic consequences and the issues surrounding the solutions. A great listen if you do not have the time to read.

Hopefully this helps broaden the awareness on current climate change issues and at the very least provides informative sources for you to refer to when needed.
