In the Amazonian heartland of Meta, Colombia, Forestbase is leading an ecosystem conservation and restoration project across 85,463.21 hectares. This includes 6,453 hectares of degraded and deforested land designated for active restoration. Our initiative is focused on protecting and reviving these vital landscapes, supporting biodiversity, and strengthening climate resilience in one of the world’s most ecologically important regions.
As part of our commitment to science-based planning and effective ecosystem recovery, our team conducted a comprehensive environmental baseline assessment. This essential first step involved a detailed analysis of soil composition, water quality, and vegetation structure to develop a clear ecological profile of the landscape.
The soil analysis revealed key information about nutrient availability, organic matter content, and erosion risks. These insights help us prioritize areas for intervention, choose suitable species, and apply restoration techniques that respond to local conditions.
The vegetation study helped map existing tree diversity, identify important seed sources, and select species that are well adapted to the region’s environmental conditions.
The water assessment provided data on pH levels and nutrient composition, allowing us to ensure a reliable and high-quality water supply to support nursery development and tree growth. This is crucial for cultivating a resilient source of native saplings.
With this knowledge, we are able to make informed, site-specific decisions that reduce environmental risks, improve survival rates, and support long-term ecosystem recovery. This baseline will also serve as a reference point in our monitoring framework, helping us track progress in forest regeneration, biodiversity, and soil health over time.
A strong environmental assessment is not just a starting point. It is the foundation for building a thriving, self-sustaining forest that delivers environmental, social, and economic value for years to come.
1. Soil Sampling: Building the Foundation for Forest Recovery
Healthy soil is essential for the success of any reforestation effort. To better understand the growing conditions across our project area, the Forestbase team conducted systematic soil sampling across multiple zones. The objective was to evaluate soil fertility, organic matter levels, and physical structure to determine suitability for tree growth and long-term forest health.
Samples were analyzed at the Soil and Water Laboratory of Jorge Tadeo Lozano University in Bogotá. The lab tested for key physicochemical properties, including pH, electrical conductivity, cation exchange capacity, organic matter, mineral nitrogen, phosphorus, and essential macro- and micronutrients.
Methodology highlights:
- Samples were collected in a zigzag pattern to ensure a representative profile of each site.
- Sampling depth reached 20 cm, targeting the root-active zone of most tree species.
- Parameters such as salinity, erosion risk, pH, and moisture retention were assessed.
These findings inform our soil preparation strategies, such as whether to apply nutrient amendments or implement erosion control techniques, helping to create optimal conditions for seedling survival and forest restoration.
2. Vegetation Characterization: Mapping Biodiversity and Guiding Species Selection
Meta’s forests host a rich array of native plant and tree species that are vital for carbon capture, soil stabilization, and local biodiversity. To assess the current state of vegetation and identify priority species for propagation, we conducted a detailed forest inventory.
Using standardized 0.1-hectare plots, randomly distributed across the project area, we recorded species composition and key dendrometric variables.
So far, 14 plots have been surveyed, and 78 native species have been identified across 32 botanical families. The most dominant tree species recorded are Virola sebifera and Oenocarpus bataua, a long-living tree that can grow up to 30 m and a long-living palm typical in the Amazon. From these 79 species, 10 species are eventually shortlisted based on certain ecological characteristics.
Key steps included:
- Identifying tree species through local taxonomy and ecological knowledge.
- Measuring diameter at breast height (DBH), total height, and canopy structure.
- Mapping seed sources to support natural regeneration efforts.
This information helps us prioritize native species with high ecological value and potential economic benefit, laying the groundwork for a resilient and biodiverse forest ecosystem.
Water Sampling: Securing a Sustainable Water Source
Water is a critical resource in any tropical forest ecosystem, especially when planning nurseries and large-scale planting. During our fieldwork, we collected water samples from local streams and rivers to evaluate quality and suitability for reforestation activities.
The analysis focused on pH levels, total dissolved solids, and the presence of contaminants such as heavy metals or agricultural runoff.
The results help us to:
- Understand the impact of nearby land use, such as agriculture or industrial activity, on local water bodies.
- Identify safe and reliable sources of water for irrigation.
- Design effective water conservation strategies to support both nursery development and long-term forest growth.
Using Data to Drive Reforestation Success
The findings from this fieldwork will guide our next steps, including:
- Developing site-specific planting plans tailored to soil and water conditions.
- Establishing a forest nursery to propagate native species for large-scale restoration.
- Monitoring ecosystem recovery over time using data-driven benchmarks.
Our commitment to scientific rigor and local engagement ensures that this project will not only restore forests but also create sustainable livelihoods for local communities.
This environmental assessment marks a crucial step toward scaling reforestation in Meta. As we move forward, Forestbase will continue leveraging scientific research, community collaboration, and cutting-edge monitoring techniques to drive impactful climate action.
