Abstract
This study assessed the abundance and mean
volume of coarse woody debris (CWD), comprising fallen logs, stumps, and snags,
across six woodland types within the Yankari Game Reserve, Nigeria. Data were
collected on frequency and estimated volumes (m³/ha) of each component at
specific georeferenced locations. Results indicated marked variation in CWD
distribution among sites. The highest total volume of CWD was recorded in
Annogeissus woodland (110.24 m³/ha), driven primarily by the abundance of large
fallen logs, while Detarium woodland also showed relatively high accumulation
(58.16 m³/ha). In contrast, the Gaji River Complex exhibited the lowest CWD
volume (32.44 m³/ha), despite recording the highest frequency of fallen logs.
Stumps and snags generally contributed negligibly to overall volume across
sites, with values ranging between 0.06 and 0.17 m³/ha. These findings
highlight spatial heterogeneity in CWD distribution, suggesting differences in
woodland structure, disturbance regimes, and decomposition dynamics. Such
variations have ecological implications for carbon storage, nutrient cycling,
and habitat availability within the reserve’s woodland ecosystems.
