Forest gained and lost, 2000–2020
- Forest in 2000
- 9,980 acres (4,040 ha)
- Forest in 2020
- 11,400 acres (4,600 ha)
- Overall change
- +1,380 acres (558 ha)more forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around McKinney grew from about 9,980 acres (4,040 hectares) to 11,400 acres (4,600 hectares), a net gain of about 1,380 acres (558 hectares) (+14%). New forest grew on about 1,790 acres (725 hectares), while 415 acres (168 hectares) were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.
