Over the past five years, the global forest carbon sector has faced a significant integrity crisis. High-profile projects have been criticized for overstating deforestation threats, leading to "phantom credits" that don’t represent genuine climate mitigation. At Tesera Systems, we believe the solution requires localized precision. We are excited to share our latest white paper on Locally Grounded Forest Carbon (LGFC), a framework designed to shift forest carbon from subjective estimation to scientific certainty.

Our LGFC solutionbridges the gap between global scale and local precision. We achieve this by fusing Planet’s daily 3-meter nominal resolution satellite monitoring with localized, machine-learning-driven precision. We put LGFC to the test at the Taiga Forest Carbon Project in Ontario, Canada, covering approximately 201,000 acres. Tesera delivered a High Resolution Forest Inventory over this project area, providing us with a robust benchmark.

The results were surprising:
* Unadjusted Planet Data: Estimated the carbon stock at 2.8 million Mg, representing only 70% of the actual carbon present.
* LGFC Estimate: Delivered an estimate of 4.3 million Mg, aligning more closely with our high-resolution ground inventory.
* This difference of about 1.5 million Mg of carbon would fundamentally change the estimated feasibility and financial impact of such a project.

Ready to ground your carbon project in scientific truth? Tesera is looking to collaborate with organizations interested in incorporating their current plot networks into the LGFC framework. Let’s work together to make "digital MRV" the new standard for excellence..

Enhanced Forest Inventories for Habitat Mapping: A Case Study in the Sierra Nevada Mountains of California

In this manuscript, we present an Enhanced Forest Inventory (EFI) and demonstrate its utility for high-resolution wildlife habitat mapping. The project area covers 270,000 acres of the Eldorado National Forest in California's Sierra Nevada.

By integrating 118 ground-truth Forest Inventory and Analysis (FIA) plots with multi-modal remote sensing data (LiDAR, aerial photography, and Sentinel-2 satellite imagery), we developed predictive models for key forest attributes. Our methodology employed a two-tier segmentation approach, partitioning the landscape into approximately 575,000 reporting units with an average size of 0.5 acre to capture forest heterogeneity.

Our analysis identified 25,630 acres of nesting and 26,622 acres of foraging habitat for the owl, and 25,636 acres of likely habitat for the fisher based on structural requirements like large-diameter trees and high canopy closure. The results demonstrate that EFIs provide a critical bridge between forestry and conservation ecology, offering forest managers a spatially explicit tool to monitor ecosystem health and manage vulnerable species in complex environments.

Hyperspectral Tree Species Detection - Large Scale Mapping of Mixed Wood Forests for Species Identification and Basal Area Estimation

Tesera partnered with Wyvern to study the impact of using hyperspectral imaging for precision silviculture. Wyvernʼs hyperspectral imaging offers a powerful, scalable tool for managing and inventorying large-scale mixed wood forests. Unlike traditional multispectral imagery, hyperspectral data captures many narrow spectral bands, revealing subtle biochemical and physiological differences between tree species. This enables accurate species identification and basal area estimation, which is critical for sustainable forest management, biodiversity monitoring and carbon stock assessment.

This study focused on a mixed wood forest area north of Sault Ste Marie, Ontario. Wyvernʼs Dragonette-002 captured high-resolution 5 m GSD 31-band hyperspectral imagery over the area in early July, 2025. The image was processed using ENVIʼs Quick Atmospheric Correction (QUAC), converting it to surface reflectance. A large variety of spectral indices were then calculated from Wyvernʼs wide spectral band range.

A Predictive Accuracy Comparison of HRIS vs. Conventional Ground Plot-based Forest Inventory

Over multiple projects and diverse forest conditions, HRIS is more accurate (than a conventional ground plot-based inventory) providing significant increases in predictive accuracy (RMSE). We conducted RMSE comparisons for inventory projects in both natural forest conditions and managed forest conditions (plantations). Across several forest attributes, HRIS provides substantial accuracy improvements over diverse forest conditions.
