North Temperate Lakes LTER Northern Highland Lake District Coarse Woody Debris Docks|湖泊生态系统数据集|生态研究数据集

Coarse woody debris (CWD) is an important, but often neglected, component of lake
ecosystems. It is ecologically valuable because it creates littoral habitat
complexity but it is susceptible to manipulation by riparian process, in particular
removal by property owners. The objective of this study is to determine the spatial
scales at which human and environmental factors contribute to coarse woody debris
input and output dynamics. Coarse woody debris, boat docks, and riparian trees (with
the potential of becoming CWD) around the five lakes of the NTL-LTER site (Trout
Lake, Allequash Lake (north basin), Sparkling Lake, Crystal Lake, and Big
Muskellunge Lake) were measured in 1996 and 1997. Boat docks were located on all 5
lakes. Docks were verified in 1997 using digital orthophotos. GPS positions were
adjusted to coincide with the photos. Many of the docks were photographed with a
digital camera.
