Harmonizing National Forest Inventories [PDF]

Forest Science, 2012
International agreements increasingly require that countries report estimates of national forest resources. The United Nations Framework Convention on Climate Change requires that countries submit annual reports of greenhouse gas emissions and removals by sources and sinks.

Using next generation sequencing of alpine plants to improve fecal metabarcoding diet analysis for Dall’s sheep

BMC Research Notes, 2021
Objectives Dall’s sheep (Ovis dalli dalli) are important herbivores in the mountainous ecosystems of northwestern North America, and recent declines in some populations have sparked concern.

Effects of traditional harvest and burning on common camas (Camassia quamash) abundance in Northern Idaho: The potential for traditional resource management in a protected area wetland

Ecology and Evolution, 2021
The bulbs of common camas (Camassia quamash) were a staple food of Indigenous Peoples of western North America for millennia. Camas harvesting site productivity was encouraged through intense management.

Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data

Annals of Forest Science, 2021
Key message Large-scale forest resource maps based on national forest inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs and forest management inventories (FMIs). A comparison of models used in such a NFI-based map and

Longitudinal height-diameter curves for Norway spruce, Scots pine and silver birch in Norway based on shape constraint additive regression models

Forest Ecosystems, 2018
Background Generalized height-diameter curves based on a re-parameterized version of the Korf function for Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth) in Norway are presented.

Age-dependence of stand biomass in managed boreal forests based on the Finnish National Forest Inventory data

, 2021
Information on carbon stocks and the rate of carbon accumulation is needed to harness the climate change mitigation potential of boreal forests. While previous studies have revealed general patterns and mechanisms for age-dependence of stand biomass ...

Site classification vs. wood production: a case study based on Silver fir growth dynamics in the Western Carpathians

Journal of Forest Science, 2011
We analysed wood production on an example of Silver fir growth ability within site units defined in the site classification that is currently used in the Western Carpathians.

Geographical spatial distribution and productivity dynamic change of eucalyptus plantations in China

Scientific Reports, 2021
The Eucalyptus spp. is fast-growing and is usually harvested at a young age, which enables efficient and sufficient timber supply. However, its negative impact on soil fertility incurs wide debates.
