“…Moreover, Legare et al (2001) and Chipman and Johnson (2002) also found no differences in understory richness or diversity at larger scales among different boreal mixedwood forest types. Miller and Chamberlain (2008) also reported a similar result in eastern Louisiana, while Oswald et al (2009) mentioned that prescribed burning and herbicide treatments increased species richness but decreased species evenness with no change in diversity index. On the other hand, several studies have documented shortterm increases in the diversity or abundance of herbs on forest sites following a single application of glyphosate or other site preparation techniques (Simard and Heinemann 1996).…”

In central British Columbia (BC), forest management practices have altered natural stand development pathways by controlling ''non commercial'' tree species and other competing species with the objective of maximizing crop tree growth. This potentially decreases overall diversity within the stand. We conducted a retrospective study on a 13-year-old stand to investigate the impacts of vegetation management with glyphosate on tree growth, species diversity and forest health in central BC. Results revealed that spruce was marginally taller than birch in the herbicide treated area and significantly shorter than birch in the untreated area. There was no difference in spruce diameter at breast height (DBH) and mean stem volume by treatment. White pine weevil attack was significantly reduced in the untreated area. In total, 133 plant species were recorded from 2002 to 2006, but 30% of the species present in 2002 were not present in 2006. Species' richness and alpha diversity were similar between treatments but beta diversity was relatively low indicating little treatment effect. There was a greater occurrence and abundance of ''weedy'' and pioneer species in the herbicide-treated area. Overall, this study suggests that glyphosate application does not remove all birch and showed minimal or no impact on under-story vegetation. Therefore, a move away from broadcast vegetation control to spot control where warranted could result in better tree growth, improved forest health and structural diversity.

“…Transient reductions in woody plant cover following herbicide application have occurred in studies of pine savannas and grasslands (e.g. Brockway & Outcalt ; Provencher et al ; Miller & Chamberlain ; Freeman & Jose ; Hutchinson & Langeland ; Iglay et al ; Addington et al ). Based on our field observations, such reductions likely result from mortality of those sections of USOs immediately associated with sprayed stems, rather than more widespread depressant effects on entire USOs, particularly more deeply buried sections.…”

Short‐term effects of herbicides and a prescribed fire on restoration of a shrub‐encroached pine savanna

Shrub encroachment occurring worldwide in savannas and grasslands has commonly been hypothesized to result from anthropogenically altered environments. Two disturbance-based approaches to restoration have involved: (1) application of selective herbicides to reduce density/cover of shrubs; (2) reinstatement of natural fire regimes to generate environmental conditions favoring herbaceous species. We studied short-term responses of native shrubs, vines, and grasses in a Louisiana pine savanna to herbicides followed by a prescribed fire and fire alone. Plots established in the summer, 2013, were hand-sprayed in the fall with Imazapyr and Triclopyr, Triclopyr alone, or no herbicide, then prescribed burned the following spring. Numbers of species of shrubs and vines at scales of 1 and 100 m 2 , numbers of stems and regrowth of stems produced by six common species of shrubs, and the number of flowering culms of perennial C 4 grasses were assessed postfire in 2014. Compared with fire alone, herbicides followed by fire resulted in (1) small reductions in species richness of shrubs and no effects on vines, (2) fewer stems comprising shrub genets, but similar postfire regrowth of resprouting shrub stems, and (3) fewer flowering culms of C 4 grasses. Underground storage organs of savanna shrubs and vines survived both aboveground disturbances. Thus, single applications of herbicides followed by fires reduced, but did not reverse shrub encroachment and negatively affected grasses. Because effects of herbicides overrode those of prescribed fires, these disturbances did not act synergistically, suggesting that reinstating natural fire regimes should be a priority in restoration of savannas and grasslands.

“…Natural resource managers have contemplated issues related to site preparation treatments. Several types of harvesting and silvicultural activities may impact plant community and biodiversity in managed forests, including the harvesting process itself, pre-harvest activities, such as pre-commercial thinning, and post-harvest site preparation activities (e.g., chemical/mechanical preparation of the site for planting) [16][17][18][19]. Various mechanical/chemical site preparation treatments are applied at station in our study region from 1982 to 2014 was 2024.7 mm with over 70% of the precipitation falling from April to September.…”

Sustained forest management of Cunninghamia lanceolata (Chinese fir) plantations in subtropical China is restricted by the limited availability of quantitative data. This study combines inventory data and tree-ring analysis of Chinese fir from natural and plantation forests that were subjected to controlled burning or brush clearing site preparations. Inter-annual variation of Chinese fir tree-ring widths were measured for the controlled burning, brush clearing and natural forest sites. The mean annual diametric growth of Chinese fir was 0.56 cm·year −1 for the natural forest, 0.80 cm·year −1 for the brush clearing site and 1.10 cm·year −1 for the controlled burning site. The time needed to reach the minimum cutting/logging diameter of 15 cm was 14 years in the controlled burning site, 19 years in the brush clearing site and >40 years in the natural forest. The biological rotation ages for the burning, cutting and natural forest sites were 15, 26 and >100 years, respectively. The total aboveground biomasses for the burning and clearing sites were 269.8 t·ha −1 and 252 t·ha −1 , respectively. These results suggest that the current 25-year cutting cycle greatly underestimates the growth rate of Chinese fir plantations.
