Introduction

TerraBio includes standardized indicators to compare performance between and across different interventions. This informs on not just performance of a management practice to achieve their desired outcomes, but also enables comparison and learning from activities in an effort to continue to refine management decisions and prioritize investments with large impacts… These indicators include land cover and land use indicators such as number of hectares directly restored due to intervention practices, biodiversity indicators such as change in key species groups at investment site, and landscape integrity indicators with the number of hectares conserved showing increases in key species.

TerraBio indicators are aligned and respond to ABF Key Performance Indicators (Table 1).

Remote Sensing Indicators Reporting Units

We calculate the four remote sensing based metrics across different geographic regions. Some are reported at the farm level, while others are reported by land use. Table 1 lists the indicators, metrics, reporting units and measurement units for each of the remote sensing derived metrics.

Table 2. Summary of reporting details for each remote sensing based metric

ABF KPI	TerraBio metric	reporting unit	measurement units
CO2 e Reduction	Carbon Sequestration - Emission Reductions	farm boundary and by land use	tons CO2 equivalent removed, normalized by area
Improved Biophysical Conditions	Regenerated/Restored Area	within intervention sites and farm total	Total ha
Landscape Conservation	Conserved Forest Area	farm boundary, excluding intervention	Total ha
Habitat Protection	Change in Patch Connectivity	farm boundary	percent area change per class

Biodiversity Indicators Reporting Units

We calculate three biodivreisty metrics.

ABF KPI	TerraBio metric	reporting unit	measurement units
Improved Species Presence	Effective Species Richness	farm boundary and by land use	number of species
	paired-site species composition comparisons	farm boundary	unitless value (0-1)
	description of species assemblage	farm boundary	total hectares

Unpacking the Geographic Reporting Units

The land uses we include in the design of TerraBio include:

1. Reference: Conserved forested area characterized by native trees.
2. Counterfactual: Practice followed if no intervention. E.g. pasture land, soy plantation.
3. Intervention Type(s) [Not all deals will have each of these land uses]:
   1. The agroforestry system or reforestation sites (the business implementation).
   2. Regeneration site: Any area left for regeneration/natural succession or managed restoration.
4. Undesignated: Note, not all areas in a farm will fall under these categories. We refer to this area in the farm that is not included as an intervention, reference or counterfactual as undesignated.

• Farm boundary(ies): Includes the farm boundaries under the deal. It usually encompasses all the other land uses, but it can happen that one land use is not within the farm boundaries.

Below we include some images to illustrate what these different reporting geographies could look like for a deal.
