“…Still, specific components of concern must be identified and continually updated to ensure that they are maintained through active management, if necessary, across the landscape and through time (Lautenschlager l996b, 1998). Franklin (1987) notes that although many sophisticated predictive models and general constructs exist, few have been tested against data (reality). The adaptive management literature suggests that management-related surprises should be expected; however, the history of forest management suggests that successes can also be expected.…”

“…Although we justify these studies by referring to other researchers using the same approach, we repeatedly fail to test management potentials and our predictive capabilities. As Franklin (1987) suggests, we conduct basic studies but rarely attempt the logical next step. In addition, although implementing extreme treatments may provide information about potential management limits, the focus on extreme rather than standard practices should be reconsidered.…”

“…Bolstered by heady success in the political action years of the 60s and 70s, ecologists seem ready and willing to move from their traditional realm of observational science to those where they have little or no expertise (Peters 1995). Yet, silviculturists were applying ecological principles centuries before "ecology" was coined Aune 1997, Smith et al 1997 have emerged as strong and charismatic voices for long-term research, e.g., Franklin (1989). Through their persistence, funds have been committed by the U.S. National Science Foundation for long-term ecological research (LTER) (Brenneman 1989).…”

Seed rain quantity and quality, 1984–1992, in a high altitude old‐growth spruce forest, northern Sweden

SUMMARYShort-term regeneration ability of a cold-marginal Picea abies forest was studied by analyzing spruce seed rain during nine years and by assessing resulting recruitment at the end of the studied period. Quantitatively large differences occurred between studied years, and seed viability was low during the whole study period. Only exceptionally did seed viability exceed 1 %. Sparse regeneration occurred in 1984, which is the year when most viable seeds/ha were recorded. In addition, the results are compared with recruitment data from the 1930s (from the same forest), a time period when regeneration peaked. It is suggested that the period 1984-1992, due to the sparse regeneration, retrospectively probably will appear as a regeneration trough or a decreasing regeneration trend. Furthermore, it is concluded that, in a long-term perspective, periodic regeneration is sufficient for maintenance of the forest because of the longevity of spruce. Additionally, climatically induced variations of regeneration success give rise to natural fluctuations in stand density.
