Forests can be beautiful and calming. They provide homes to wildlife, and places for hikers to muddy their boots.
But more than that, they’re dynamic ecosystems that store carbon, clean our air, support biodiversity, and play a big role in counteracting climate change. However, managing forests sustainably is a challenging task that requires accurate data on forest health, growth patterns, and resource needs. This is where biomass monitoring comes into play, offering a data-driven approach to sustainable forestry.
Forestry is the management of forests, woodlands and tree-covered landscapes for a range of purposes, including;
Natural Forests: These are forests that have developed naturally over time without significant human intervention, such as primary or old-growth forests. Forestry in these contexts often involves conservation, biodiversity management, and sustainable use.
Plantation Forests: These are forests deliberately planted and managed by humans, often for timber production, carbon sequestration, or other economic purposes. Forestry practices here focus on planting, thinning, harvesting, and replanting.
Agroforestry: This involves integrating trees into agricultural landscapes, combining forestry with farming to improve productivity, soil health, and biodiversity.
Restoration Forestry: Focused on restoring degraded or deforested landscapes, reintroducing native tree species, and rebuilding ecosystems.

Sustainable forestry is about striking a balance between human resource needs and environmental health. Unlike traditional forestry practices, which often prioritize resource extraction, sustainable forestry focuses on long-term forest health. This approach preserves biodiversity, safeguards water resources, and supports the communities that depend on forests.
With practices that range from selective harvesting to controlled replanting, sustainable forestry aims to maintain a forest’s ecosystem services for generations.
At its core, sustainable forestry is about responsible stewardship. Forests cover 31% of the Earth’s land, store an estimated 296 gigatonnes of carbon, and are home to the majority of the world's terrestrial biodiversity. Forestry plantations are estimated to account for 7.35% of total global forests, equating to4.6% of total global biomass. They are invaluable for their role in carbon sequestration – a process where forests absorb and store carbon, effectively offsetting emissions from other sources. Sustainable forestry practices help ensure these carbon sinks remain robust and resilient.
In forestry, “biomass” refers to all organic material within the forest, including trees, plants, leaves, and even the soil. Biomass is a powerful carbon store – trees absorb CO₂ from the atmosphere, converting it into carbon-rich biomass through photosynthesis. Traditionally, biomass monitoring in forestry plantations is used as a metric for understanding the economic value of the wood.
For sustainable forestry, understanding biomass levels is essential as this stored carbon helps offset greenhouse gas emissions, making forests a critical ally in the fight against climate change. By knowing how much biomass a forest contains, managers can estimate the carbon it captures and make decisions that preserve or enhance its capacity for carbon storage. Biomass monitoring is an essential tool that provides this information. For plantations, this helps teams make informed choices about which trees to harvest, when to replant, and how to maximize growth potential in their forest. For natural ecosystems and restoration forestry, this assists in protecting ecosystems and ensuring health of the project.
Timber Harvesting as a Carbon Mitigation Strategy: Harvesting trees initially releases carbon, but this perspective overlooks the broader carbon dynamics. Sustainably harvested forests regrow and recapture carbon over time, creating a “closed loop.” Additionally, wood products derived from these forests continue to store carbon for years or even decades. Using wood instead of energy-intensive materials like steel further reduces emissions by avoiding fossil fuel use in manufacturing.
Substitution and Sustainable Wood Use: Substituting wood for fossil-fuel-intensive materials is an effective way to reduce emissions. For instance, wood products require less energy to produce than concrete or steel. Using wood as an energy source in place of coal also keeps fossil fuels in the ground, while biogenic carbon emissions from wood are offset by forest regrowth.
Biomass monitoring is increasingly being recognized as an essential component of sustainable forestry. With the aid of remote sensing technologies and data analysis tools like Birdi, forestry managers can now access accurate, timely information on forest conditions. This data-driven approach makes it easier to maintain sustainable practices that support forest health, biodiversity, and carbon sequestration.
As the world continues to focus on sustainability, biomass monitoring will likely become a standard practice in forestry. The information it provides allows for more informed decision-making, creating a path toward a future where forests are preserved, carbon storage is optimized, and resources are managed responsibly.
Sustainable forestry is essential to balancing resource needs with environmental preservation. By embracing biomass monitoring, forestry managers gain valuable insights into forest health, supporting practices that align with long-term sustainability goals. Whether it’s through analyzing canopy coverage, monitoring tree height, or tracking growth patterns, biomass monitoring empowers us to manage forests responsibly and ensure they continue to thrive.
