Special Issue "Post-Disturbance Forest Management and Regeneration Dynamics"
Deadline for manuscript submissions: closed (10 August 2017)
Natural disturbances have been shaping species composition and the spatial pattern of vegetation cover in forest ecosystems for millennia, being among the main drivers of stand dynamics and forest succession. However, many stands are of anthropogenic origin or have been deeply affected by forest management, and the impact of high severity disturbances can lead to undesirable successional pathways. Furthermore, in many regions, disturbance regimes have already undergone considerable changes, in particular through an increase in frequency, size, and severity, strictly related to climate and land use changes.
Emerging critical issues related to current and foreseen alterations in disturbance regimes call for a better understanding of both regeneration dynamics following intermediate or high severity events and the impact of post-disturbance management practices on forest recovery. This advance in knowledge will prove fundamental prior to choosing between the need to actively undertake forest restoration or a passive management approach.
We encourage studies from all fields, including experimental and multidisciplinary investigations, focusing on post-disturbance regeneration dynamics, and management interventions, to contribute to this Special Issue in order to promote knowledge on forest ecosystems affected by natural disturbances, and to implement sustainable forest management, aiming at increasing forest resilience and securing their fundamental ecosystem services and inherent biodiversity.

Title: Regeneration Dynamics of Coast Redwood, a Sprouting Conifer Species: A Review with Implications for Restoration
Author: Kevin L. O'Hara 1

Abstract: Coast redwood (Sequoia sempervirens) is unique among conifer species because of its longevity, great sizes of individual trees, and its propensity to reproduce through sprouts. This sprouting capability includes sprouting from burned trees, cut stumps, down logs, and even severed branches or tree tops. Conversely, redwood is not effective at reproducing sexually. Resulting old forests have complex spatial patterns of clones intermixed with other unique individuals. After disturbance or harvest, healthy stumps sprout vigorously, often producing dozens of sprouts within two years of disturbance. These sprouts form highly aggregated spatial patterns because they are clustered around stumps that may number less than 50 ha-1. Growth and self-thinning of sprouts is rapid in full-sunlight. In partial shade, self-thinning may be rapid but growth may be slow. Entire sprout clumps may die in low quality light environments. Thinning of sprouts can accelerate individual tree growth, providing an effective restoration strategy to accelerate formation of large trees and old forest structures or increase stand growth for timber production. This paper reviews the science of early stand dynamics in coast redwood and their implications for restoration and other silvicultural strategies.
Title: Natural Succession and Heterogeneity Following High-Severity Fire in Ponderosa/Jeffrey-Pine and Mixed-Conifer Forests of California, USA

Abstract: Researchers and land managers are increasingly attempting to understand natural succession patterns following large high-severity fire patches within conifer forests to better understand ecological resilience. However, little attention has been paid to the influence of plot size on conclusions about the extent and degree of forest regeneration. I investigated this issue in three fire areas in mixed-conifer and Jeffrey pine forests in the mountains of southern California, U.S.A., recording the proportion of plots containing natural tree regeneration (both conifer and non-conifer), and the density of regenerating stems, at four radius distances from plot center points in large high-severity fire patches.
Title: Salvage-Logging after Windstorm Leads to Structural and Functional Homogenization of Understory Layer and Delayed Spruce Tree Recovery in Tatra Mts., Slovakia
Author: Miro Svoboda
Abstract: Stand-replacing disturbance and post-disturbance salvage-logging influence the forest succession in different ways, but in many forest ecosystems there is still limited knowledge how salvage-logging affects vegetation patterns compared to natural development. In this study we described the diversity pattern of understory vegetation and tree regeneration in mountain spruce forest of Tatra Mts., northern Slovakia, which was subject to high severity windstorm over 10 000 ha in 2004 and then subsequent salvage-logging. We asked how severe salvage-logging modified the species composition, vegetation diversity and its spatial heterogeneity. Vascular plants, deadwood coverage and tree species densities were recorded on non-intervention (NI; n=106) and salvage-logged (SL; n=93) study plots (spatially nested design, sample plot area 3.14 m2) 6 (7) years after disturbance. The non-intervention sites were structurally more diverse, with post-windstorms legacies such as dead wood and pits and mound topography. It contained more late-successional plant species and mosses from the pre-disturbance forest; was more diverse in terms of alpha- and beta-diversity and the spruce regeneration was more abundant there. The salvage logged site was more homogeneous and its composition shifted towards the dominance of graminoids, although the latter site accommodated higher number of plant species due to newly established pioneer plant- and tree species. The retreat of late-successional species in favor of graminoids can lead to structural and functional homogenization of habitat and delayed succession towards to spruce forest establishment. The machinery removing of wind-disturbance legacies significantly divert successional pathways. Large-scale application of salvage-logging would reduce beta-divesity of landscape and should be avoided in national parks.
