“…Table 3 compares mean woody debris volumes and surface areas from this study with those from other New Zealand studies of woody debris in native forests and pine plantations. Woody debris volumes in this study were similar to those found in streams of mature and 15-year-old pine plantations and older native forests (Evans et al 1993b;Quinn et al 1997;Collier et al 1998) (NB. Evans measured all woody debris >2.5 cm).…”

“…Evans measured all woody debris >2.5 cm). The young (10-year-old ) native and pine plantation streams had mean woody debris volumes which were much lower than the volumes in this study (Evans et al 1993b).…”

“…LWD also accounted for most of the woody debris in the pine plantation and native streams of Quinn et al (1997). Evans et al (1993b) found that LWD contributed to c. 50% of wood surface areas in the ancient native forests. However, SWD contributed to most of the woody debris in the 120-year-old forest.…”

“…Woody debris volumes and surface areas in the pine plantation streams of New Zealand have been compared with streams of similar size and order in the temperate native forests of New Zealand (Evans et al 1993b;Quinn et al 1997;Collier et al 1998) and the temperate forests of North America (Harmon et al 1986;Carlson et al 1990;Robison & Beschta 1990). Woody debris volumes and surface areas include all material >1 cm in diameter, LWD volumes, and surface areas include all material >10cm.…”

“…Little data is available on the amount and distribution of woody debris in pine plantation streams, particularly in the small first-to third-order streams, where woody debris has the most influence on stream dynamics (Harmon et al 1986;Sedell et al 1988;Bilby & Ward 1989). Woody debris characteristics have been measured by: Evans et al ( 1993b) in two streams in 10-year-old pine plantations; Quinn et al (1997), in three streams of 15-year-old pine plantations; and Collier et al (1998) in three streams in mature and recently harvested pine plantations in New Zealand.…”

To assess the impact of harvesting on woody debris volumes in streams, a method was required with sufficient precision to provide meaningful evaluation and comparison of pre-and postharvest levels of woody debris. Before harvest, woody debris volumes were measured in 24 first-to third-order stream sites in New Zealand's mature pine plantations (22-34 years of age). An adaptation of the Van Wagner line intersect method was used to measure the small woody debris 1-9 cm in diameter (SWD). All large woody debris 10 cm in diameter (LWD) was measured for diameter and length. Woody debris volumes in the stream channel ranged from 2 to 345 m 3 ha -1 , averaging 112 m 3 ha -1 (±34, 95% confidence interval (CI)). Woody debris surface areas averaged 2883 m 2 ha -1 (±688), range 220-6769 m 2 ha -1 . Most of the woody debris volume (87%) was composed of LWD. Sixty-seven percent of the woody debris volume was located above the stream, the remainder was lying in-stream or on the floodplain. Woody debris volumes in streams of mature pine plantations in New Zealand were similar to woody debris volumes in streams of temperate native forests in New Zealand and North America. These sites will be remeasured after harvest to identify any changes in woody debris characteristics. M98014

Large wood is an important physical component of woodland rivers and significantly influences river morphology. It is also a key component of stream ecosystems. However, large wood is also a source of risk for human activities as it may damage infrastructure, block river channels, and induce flooding. Therefore, the analysis and quantification of large wood and its mobility are crucial for understanding and managing wood in rivers. As the amount of large-wood-related studies by researchers, river managers, and stakeholders increases, documentation of commonly used and newly available techniques and their effectiveness has also become increasingly relevant as well. Important data and knowledge have been obtained from the application of very different approaches and have generated a significant body of valuable information representative of different environments. This review brings a comprehensive qualitative and quantitative summary of recent advances regarding the different processes involved in large wood dynamics in fluvial systems including wood budgeting and wood mechanics. First, some key definitions and concepts are introduced. Second, advances in quantifying large wood dynamics are reviewed; in particular, how measurements and modeling can be combined to integrate our understanding of how large wood moves through and is retained within river systems. Throughout, we present a quantitative and integrated meta-analysis compiled from different studies and geographical regions. Finally, we conclude by highlighting areas of particular research importance and their likely future trajectories, and we consider a particularly underresearched area so as to stress the future challenges for large wood research.
