Leveraging remote sensing and crowd-sourced biodiversity data for enhanced plant functional trait mapping
This research introduces a novel multiresolution approach to map plant functional traits (SLA, LNC, LPC) and their higher-order moments globally at 1-km resolution. It combines optical remote sensing, crowd-sourced biodiversity records (GBIF), and plant trait databases (TRY). The methodology improves upon traditional methods by integrating PFT fractional information and adaptive sampling, addressing biases and spatial heterogeneity. While plot-level agreement with sPlotOpen is modest due to scale mismatches, the top-of-canopy weighted mean (TWM) approach, aligned with optical sensor sensitivity, shows improved performance (R² up to 0.38, relative RMSE 11-15%). The resulting maps provide crucial, spatially explicit trait distributions, enhancing ecological modeling and understanding of ecosystem functioning, biodiversity patterns, and responses to global environmental changes.
Executive Impact
This innovative approach provides highly detailed global maps of plant functional traits, moving beyond simple averages to include crucial higher-order moments like standard deviation, skewness, and kurtosis. This level of detail is critical for advancing Earth system models, improving predictions of vegetation carbon stocks and fluxes, and enabling more nuanced representations of ecosystem responses to climate change. By addressing data sparsity and sampling biases through integrated remote sensing and crowd-sourcing, it offers a scalable solution for understanding functional diversity, supporting targeted conservation efforts, and guiding future sampling strategies.

Trait Mapping Innovation
This research pioneers a multiresolution approach that integrates optical remote sensing, crowd-sourced biodiversity records (GBIF), and plant trait databases (TRY) to generate high-resolution, spatially explicit maps of plant functional traits (SLA, LNC, LPC) and their higher-order moments (standard deviation, skewness, kurtosis) at a 1-km resolution. This methodology moves beyond traditional plant functional types (PFTs) by characterizing full trait distributions, providing a more nuanced understanding of vegetation diversity and ecosystem processes.
Addressing Data Biases
A key innovation is the integration of PFT fractional information and an adaptive sampling strategy to correct for significant sampling biases inherent in crowd-sourced data. By modeling spatially explicit fractional PFT distributions and adaptively determining optimal sampling quadrat sizes, the method mitigates issues of uneven observation coverage, bias towards accessible regions, and underrepresentation of certain ecosystems. This enhances the representativeness and spatial detail of the trait maps.
Ecological & Predictive Value
The generated maps provide unprecedented detail for understanding biodiversity patterns, ecosystem functioning, and trait-mediated coexistence. By quantifying higher-order moments beyond simple means, the research enables a more accurate representation of plant functional diversity in Earth System Models (ESMs) and Dynamic Global Vegetation Models (DGVMs). Benchmarking against sPlotOpen data, particularly with a top-of-canopy weighted mean (TWM) comparator, demonstrates improved agreement consistent with optical sensor sensitivity, enhancing the utility for assessing global environmental changes and ecosystem resilience.
