The basal area of uncut overstory increased gradually during the first 5 years of the study ().However, between the first and third years mean residual basal area (m 2 ha −1) decreased from to in the PC50 treatment, from to in the PC treatment, and from to in the clearcut results reflect a greater windthrow risk to both conifers and hardwoods Cited by: Natural regeneration patterns of conifer species were studied. Seedling regeneration follows patterns responding to stand structure and site condition factors along shade and drought tolerance gradients. Our findings can assist in adaptive forest management for maintaining sustainable regeneration and plant biodiversity. Seedling regeneration can vary with stand factors of overstory Cited by: 3.

Our observation that advance regeneration was common in all stands regardless of whether treatments included prescribed fire raises important questions with respect to advance regeneration in dry mixed conifer forests. First, the conditions under which advance regeneration is likely to release following treatments are not by: 6.
Resilience and regeneration after wildfire in dry mixed-conifer forests of the U.S. northern Rockies 1. Westerling et al. Increase in the frequency of large Combined effects of 20th century management have led to changes in: species composition, stand density.
Forest regeneration is a key element in achieving sustainable forest management. Partial harvest methods have been used extensively in temperate broadleaf and mixedwood ecosystems to promote regeneration on poorly stocked sites and to maintain forest composition and productivity.
However, their effectiveness in promoting conifer establishment has yet to be demonstrated in Cited by: Mixed Conifer Habitat.
Habitat Description, Status and Importance. Mixed conifer is a common forest habitat in northern Arizona found primarily in the White Mountains, the Mogollon Rim and on the Kaibab Plateau, with limited distribution on mountain islands in southeastern Arizona.
Similar habitats are found throughout the Rocky Mountains. Failure of conifer regeneration in the presence of thick ericaceous understory is a widespread phenomenon in Europe and North America, causing significant loss of forest productivity. Plants such as bilberry, crowberry, heather, Labrador tea and sheep laurel are known to cause growth inhibition in conifers such as Norway spruce, Scots pine.
s, fires in warm/dry mixed-conifer forests of the Southwest were relatively frequent and low severity. For example, Swetnam and Baisan () provided a summary of tree-ring studies conducted at 24 mixed-conifer sites in Arizona and New Mexico, and.
Managing competing vegetation is crucial in stand establishment strategies; forecasting the abundance, composition, and impact of competing vegetation after harvesting is needed to optimize silviculture scenarios and maintain long-term site productivity.
Our main objective was to identify factors influencing the short-term abundance and composition of competing vegetation over a large area of Cited by: 2.
Taken together, these conditions create challenges for managers aiming to reestablish natural fire patterns and sustain mixed-conifer forests. To limit the dominance of resprouting shrubs and facilitate conifer regeneration after overstory thinning and prescribed fire, managers may need to consider new or more intensive approaches to forest.
Mixed Conifer Ecosystem Warm/dry mixed conifer forests in the Southwest are generally located at the lower elevation of the continuum on predominately southerly aspects. These forests are dominated by fire resistant ponderosa pine (P. ponderosa) and Douglas-fir (Pseudotsuga menziesii) and also includes species adapted to mesic conditions such as.

Fire severity effects on conifer regeneration and other factors. Mean conifer seedling densities were unimodally related to fire severity: They were highest at low‐moderate and high‐moderate fire severities, lowest at high fire severity, and intermediate in the unburned controls and low severity (Fig.
6; F =P Cited by: The suite of species available for regeneration of a site, large or small, is a cumulative effect of disturbances and varies across multiple environmental gradients that include moisture. We established a long-term experiment in a temperate mixedwood stand to evaluate the effectiveness of silvicultural treatments in regenerating a mixed-species cohort while maintaining the dominance of conifers.
Silvicultural treatments included clearcutting using careful logging around advanced growth (CLAAG), uniform shelterwood (US), group shelterwood with (GS-s) or without Cited by: 1.
