Why Plant Trees

Discover the silent superheroes of nature and their incredible impact on climate change and biodiversity.

Why Plant Trees?

In a world grappling with environmental challenges and changes, the simple act of planting trees has emerged as a powerful solution to combating climate change, preserving biodiversity, contributing to sustainable economic growth and enhancing human well-being. Trees are nature's silent superheroes. They work 24/7 to improve air quality, protect water sources, and provide habitats for native wildlife, all while offering countless benefits to humanity. This blog will explore and discuss the benefits of tree planting and finish by giving you some tips on getting the most environmental benefits out of your trees.

The Climate Warriors 

Trees are the warriors that battle against climate change. Did you know that a mature tree can absorb around 10kg of carbon dioxide each year and release approximately 117kg of oxygen? Trees’ ability to photosynthesise allows them to absorb carbon dioxide, a harmful greenhouse gas contributing to global warming. Trees are carbon sinks that are able to mitigate human impact on the environment through their carbon absorption. Furthermore, they regulate temperatures, conserve energy by providing shade and reduce the need for excessive heating and cooling. According to One Tree Planted, trees can reduce ambient temperatures by up to 8° Celsius in cities, making them a valuable asset in combating the urban heat island effect. We can create a greener and cooler environment by planting trees, reducing our carbon footprint and fostering a more sustainable future. 

Guardians of Biodiversity

Trees are not mere bystanders in the web of life but the guardians of biodiversity. Trees provide a habitat for over 80% of the world's terrestrial biodiversity, according to One Tree Planted. A single tree can support hundreds of species, ranging from birds and animals to insects and fungi. Planting a diverse range of tree species means we can create vital habitats that support billions of organisms and enhance their chance of survival and proliferation. The presence of trees ensures that forest creatures have a place to forage, sleep and breed, all of which preserves regional biodiversity and maintains the delicate balance of unique ecosystems. By engaging in biodiversity planting initiatives, we can protect, support and restore natural habitats to create an interconnected network that allows for the diversity of wildlife and the preservation of endangered species.

Environmental Resilience 

Trees are a vital component in environmental resilience. The UN Food and Agriculture Association claims that a full-grown tree is able to obstruct more than 15,000 litres of water each year. Their complex root systems act as natural filters that can reduce soil erosion and prevent pollutants from entering important freshwater bodies. Absorbing excess water helps to mitigate risks of flooding and landslides, which have become more prominent as an effect of climate change. Moreover, trees play a vital role in nutrient cycling, promoting healthy soil and supporting the growth of other plant species.

Health and Well-being

Trees are renowned for enhancing both our physical and mental well-being. Numerous studies have shown that spending time outdoors, specifically around trees, reduces stress and anxiety and improves our overall mental health and mood. Nature has a kind of calming effect that promotes relaxation and forms a sense of connection to the natural world. Trees are also essential in air purification by filtering out pollutants and thus provide us with cleaner air to breathe. In addition, their shade reduces harsh sun rays, which minimises the risk of sun damage and heat-related illnesses. Whether it is a stroll through a forest, a picnic under a tree, or simply enjoying the serenity of a tree-filled garden, trees have a profound impact on our well-being.

Sustainable Economic Growth 

Forests provide jobs to over 1.6 billion people globally, claims One Tree Planted, making them essential for economic growth. The forestry sector offers diverse employment opportunities, from forest management and timber harvesting to ecotourism and research. Moreover, forests contribute significantly to the global economy by supplying timber and forest products for the construction, furniture manufacturing, and paper production industries. The economic value of forests extends beyond traditional industries, as they serve as a rich source of medicinal plants, contributing to the development of pharmaceutical products. Need more proof of their economic impact? A blog by the Arbor Day Foundation states that studies have shown that if you have trees in your garden, your home’s value increases by up to 15%. With their significant contributions to all areas of the economy, forests are invaluable resources that deserve our attention and conservation efforts.

Tips For Planting Trees

Have we convinced you yet? If you’re interested in planting trees but want to avoid all the admin and heavy labour, you can fund trees via one of our subscription plans. If you want to take a more hands-on approach, here are some planting tips to get the most out of your trees:

1. Plan your site:

  • Clearly define your goals and objectives for the project.
  • Explore funding options available to support your endeavour.
  • Identify existing vegetation or seed sources that can be protected and enhanced.
  • Consider staging your project over multiple years for easier maintenance.

2. Choose the right trees for your location:

  • Seek guidance from local councils, nurseries, and neighbouring areas.
  • Take into account environmental factors like soil type, terrain, and climate conditions.
  • Here’s a resource for native trees you could plant. 

3. Ecosource your native trees:

  • Opt for seedlings grown from locally collected seeds for better survival and growth rates.
  • Inquire about sourcing seedlings from your supplier to ensure they are eco-sourced.

4. Plant a mix of species at different times:

  • Begin with hardy nursery species like flaxes, cabbage trees, and manuka.
  • Once established, introduce secondary species such as matai and rimu.
  • The existing seedlings provide protection for slower-growing forest species.

5. Link in with other planting projects:

  • Connect with local councils to explore catchment groups in your area.
  • Collaborate with neighbours to join efforts and expand planting areas.
  • Look for local planting programs or initiatives that you can participate in.

6. Get planting advice and help:

  • Check out our very own Native Bird Dictionary for guidance on attracting native birds.  
  • Refer to the Department of Conservation for information on bird-friendly plants and their seasonal availability.

7. Consider trees for instream ecology:

  • Plant trees along waterways to improve water quality and provide habitats for eels and native fish.
  • Ensure shading restricts aquatic plant and algae growth and maintains suitable water temperatures.
  • Create an essential food source for aquatic animal life.


Amid our world's drastic environmental challenges, tree planting emerges as a thread of hope, intertwining the realms of climate change mitigation, biodiversity conservation, human well-being and sustainable economic growth. The remarkable power of trees to clean our air, protect our ecosystems, and provide countless benefits is truly amazing. By supporting tree-planting initiatives, whether that be funding trees or planting them yourselves,  each of us can make a tangible and lasting impact on the world around us.
