Table 4. Comparing Haiti forest cover estimates based on satellite data with previous studies on the period 1972–2015.

We compared our estimates of forest cover with the estimates from seven previous studies. Forest cover areas are provided in percentage.

Sources	Location	Forest cover (%)	Methods	Agency	Date	Forest definition
Lanly (1982)	Tropics (include Haiti)	1.73	Landsat 1 & 2	FAO	1972 & 1978	Broadleaved woody vegetation with more than 10% canopy cover.
Ortiz-Chour, Davis & Pugliese (2000)	Tropics (include Haiti)	3.2	Compilation of National Statistics.	FAO	2000	Woody vegetation with >10% crown cover including plantation; excludes trees for agricultural production.
Food and Agriculture Organization of the United Nations (2010)	Global Forest	4	National forest inventories compiled by the FAO	FAO	2010	Woody vegetation with >10% of tree crown cover >5-m tall. Closed forests with tree crown coverage >60%.
Álvarez-Berríos et al. (2013)	Great Antilles	8	MODIS Vegetation Index image; random forest classifier	NA	2000 & 2010	Trees and shrubs with >80% cover.
Hansen et al. (2013)	Global Forest	16.17	Wall to wall 30 m resolution Landsat images.	University of Maryland	2013	>25% canopy (2013), >5 m height, tree cover.
Churches et al. (2014)	Haiti	29.4 & 32.4	Modified normalization method using pseudo-invariant polygons, Landsat 5 image classification.	NA	2010	Vegetation greater than 5 m in height with a canopy cover of ≥10%. Includes mangroves. Exclude fruit plantations.
Hedges et al. (2018)	Haiti	0.32	Landsat 5, 7 & 8	N /A	1984–2016	Old growth with closed forest cover canopy (≥70% tree cover) with little to no human intervention.
This study	Haiti	26.4 & 21.3	Wall to wall 30 m resolution Landsat images using GEE	NA	2000 & 2015	Dominant tree cover class with moderate canopy (≥10%; 80% or more cells in the training polygons are trees).
