The influence of forest harvesting on landscape spatial patterns and old-growth-forest fragmentation in southeast British Columbia
Habitat fragmentation is considered one of the major conservation issues of recent decades. We tested predictions of landscape patterns in a 352,253-ha managed forest area in southeast British Columbia. We did this by focussing on forest fragmentation concerns among old-growth, harvest, and wildfire patches in 44 delineated landscapes using patch indices as measures of landscape pattern. We found ...

Impacts of harvest residue management on soil Carbon stocks in a plantation forest
The impacts of plantation forest management on soil C stocks in New Zealand need to be better understood for the purposes of C accounting under the Kyoto Protocol. We investigated the impacts of three harvest residue management treatments on C and N stocks in a scoriaceous forest soil: whole-tree harvesting plus forest floor removal, whole-tree harvesting, and stem-only harvesting. Volumetric ...

Soil CO2 efflux in uneven-aged managed forests: temporal patterns following harvest and effects of edaphic heterogeneity
AbstractForest management is expected to influence soil CO2 efflux (FCO2) as a result of changes in microclimatic conditions, soil properties, and root dynamics. We measured FCO2 during the growing seasons of 2003 and 2004 in both gap and non-gap locations within stands ranging from 0 to 10 years after the most recent harvest in a selection-managed northern hardwood forest in central Ontario, ...

Leveling the Playing Field for Legal Timber in Brazil
Brazil is one of the most biologically diverse countries in the world. What is less known is that the country is the fourth largest industrial roundwood (timber left as logs, not sawn into planks) and wood pulp producer and ninth largest paper producer in the world. Brazil’s forest sector contributed 5 percent to the national gross domestic product in 2012. Brazil’s forests are not ...

Book Byte: We Can Reforest the Earth
Protecting the 10 billion acres of remaining forests on earth and replanting many of those already lost are both essential for restoring the earth’s health. Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 million acres. Restoring the earth’s tree and grass cover protects soil ...

The wealth of forests
The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity. As I subsequently watched these forests dwindle and, ...

Opportunities to Generate Cash Flow for Family Forests Using Conservation Payments
There has been significant discussion about the merits of stacking conservation payments over the past few years. A simple explanation for credit stacking is when landowners are paid for conservation practices on their property that provide multiple benefits to the environment. Examples of credits types that might be stacked include: endangered species, water quality, wetlands, and carbon. ...

Time for Trees to Pack Their Trunks?
As climate changes, forest ecosystems will need to shift to more suitable sites. Should humans lend a helping hand? During the last two springs, contract planters for The Nature Conservancy have spread out through the pine, spruce and aspen forest of northeastern Minnesota. Wielding steel hoedads, they have planted almost 110,000 tree seedlings on public land. What’s noteworthy about ...
