A framework for ecological restoration cost accounting across context and scale
Bibliographic record
Abstract
Restoration programs that can deliver implementation outcomes across large-scales are critical to achieving global conservation targets such as Target 2 of the Kunming-Montreal Global Biodiversity Framework. Yet, limited funding poses a strong barrier to the achievement of these ambitious goals, suggesting the adoption of emerging technologies capable of delivering cost-effective solutions to restoration at scale may be required. To date, there has been limited reporting of restoration implementation costs at scales that are meaningful for decision making, hindering the capacity for evidence-based comparisons of existing and emerging restoration methods. Here, we demonstrate the application of a detailed, framework that addresses the shortcomings of previous frameworks by matching the costs of conservation actions to their outcomes across multiple scales. We estimate the financial costs of two planting methods from the perspective of a restoration practitioner comparing an established method (tubestock planting) to an emerging method (drone seeding: seed pelleting and delivery via drones), across five spatial scales (1, 10, 100, 500, and 1,000 hectares). Using data from a hypothetical case-study, we show that both methods exhibit economies of scale (decrease in the cost per hectare to action with increase in scale); however, the economies of scale were greater for drone seeding. Our framework allows for transparent cost accounting of project implementation, to guide practitioners and policy makers when budgeting and reporting costs for future projects. Users of this framework can also explore if and how context influences the costs of restoration to maximise the delivery of cost-efficient restoration at scale.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
