The study was conducted at
Gashaka Gumti National Park to assess the land cover changes of Gashaka Gumti
National Park within 21 years
window (1991 to 2011) using satellite imageries. Results showed that in 1991,
2001 and 2011, Guinea Savannah covered 41% (2762.01 km2), 38%
(2565.01 km2) and 36% (2449.23 km2) of the land area
respectively. Derived Savannah covered 31% (2086.85 km2), 33%
(2185.41 km2) and 31% (2072.39 km2) respectively in the
stated years. Montane Forest covered 12% (775.28 km2), 12% (822.02 km2)
and 14% (941.11 km2) respectively in the years under consideration.
For Gallery Forest, 16%, 17% and 19% were recorded for the stated years
respectively. This indicated that Guinea Savannah decreased by 7.13% (﹣197 km2),
Derived Savanna, Montane Forest and Gallery Forest increased by 4.72% ( 98.56 km2), 6.03%
( 46.74 km2)
and 4.67% ( 51.7 km2)
respectively between 1991 and 2011. Between 2001 and 2011, Guinea Savanna and
Derived savanna decreased by 4.51% (﹣115.78 km2) and 5.17% (﹣113.02 km2),
respectively, while Montane and Gallery forests increased by 14.49% ( 119.09 km2)
and 9.47% ( 109.71 km2) respectively. The changes recorded were considered
marginal. Similarly, the temperature and rainfall dynamics established in the
study were not of such magnitude that could negatively impact on the landcover
classes.
