Deforestation · 2001–2025
Which has lost more forest, Mandeville or May Pen?
Mandeville has lost more: about 1,840 ha of forest within 10 km of its center from 2001 to 2025, against 1,280 ha around May Pen. 1,840 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2005, with 371 ha lost.
Worst year: 2005, with 227 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Mandeville vs May Pen: your questions answered
Is Mandeville cleaner than May Pen?
On air quality they are level right now: both read 53 on the US EPA index. Air quality changes through the day, so this can separate within hours. Over the past 6 days, on modeled daily averages, Mandeville averaged AQI 41 against 45, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Mandeville and May Pen today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Mandeville reads AQI 53 and May Pen reads AQI 53.

Which has more trees, Mandeville or May Pen?
May Pen has more tree cover: 46.9% of the land within 2 km of its center against 45.0% around Mandeville, or about 147,341 trees against 141,372. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Mandeville and May Pen need?
Mandeville needs about 0 more to reach its canopy target of 30%, and May Pen about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Why can two places 29 km apart read differently?
Air changes over short distances with traffic, industry, wind and hills, and each reading comes from the nearest ground stations or, where there are none, from a regional model. A gap of a few points between neighbors is within normal variation, while a gap that crosses an EPA band is worth noticing.
Are Mandeville and May Pen measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings are model estimates, with no ground station close enough to either. Nothing is adjusted for population, city limits or climate.
How often does the Mandeville vs May Pen comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 10, 2026 and Sep 15, 2026), and the forest figures are published yearly.
