Forest sampling techniques in different types of vegetation applying plot sampling, non-plot sampling, and remote sensing

open access: yesNova Geodesia
Forest inventories are undergoing rapid changes due to an increasingly complex set of economic, environmental, and social policy objectives. Therefore, the objective is to identify, analyse, and discuss the main forest inventory methods at global ...

A method for estimating the stand characteristics of a forest compartment using satellite imagery.

open access: yesSilva Fennica, 1984
The paper presents a method based on two phase sampling and applicable to forest inventories. The first phase estimates are obtained from satellite imagery and, if required, from extra material such as maps.

The role of predictive model data in designing mangrove forest carbon programs

open access: yesEnvironmental Research Letters, 2020
Estimating baseline carbon stocks is a key step in designing forest carbon programs. While field inventories are resource-demanding, advances in predictive modeling are now providing globally coterminous datasets of carbon stocks at high spatial ...

Forest Inventory

open access: yes, 1970
Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows the volume and type of standing wood by provincial forest districts. Wood type is broken down by hardwood and softwood. Included is a graph that shows the number of cubic feet of various tree species per province and territory.

Katam Forest app for forest inventories

open access: yesScientia Forestalis
ABSTRACT New methodologies for forest measurement have been developed to provide technological advancements and optimization in data collection for forest inventories. In this context, the Katam Forest app was developed for use on smartphones, aiming to measure dendrometric variables based on video recordings.

The renaissance of National Forest Inventories (NFIs) in the context of the international conventions – a discussion paper on context, background and justification of NFIs

open access: yesPesquisa Florestal Brasileira, 2017
National Forest Inventories (NFI) cover whole countries and strive to put the resource forest and the ecosystem forest into a quantitative framework. While for forest management inventories it is very obvious that they shall support management decisions ...

A call for improving forest socioeconomic data with inspiration from national forest inventories

open access: yesSilva Fennica
National forest inventories have long and strong traditions in many countries and they can offer a wealth of information about the biophysical aspects of forests such as tree growth, carbon fluxes and biodiversity.

Relative Efficiency of ALS and InSAR for Biomass Estimation in a Tanzanian Rainforest

open access: yesRemote Sensing, 2015
Forest inventories based on field sample surveys, supported by auxiliary remotely sensed data, have the potential to provide transparent and confident estimates of forest carbon stocks required in climate change mitigation schemes such as the REDD ...

SPATIAL SCALE EFFECTS OF SAMPLING ON THE INTERPOLATION OF SPECIES DISTRIBUTION MODELS IN THE SOUTHWESTERN AMAZON

open access: yesRevista Árvore
Knowledge of the geographical distribution of timber tree species in the Amazon is still scarce. This is especially true at the local level, thereby limiting natural resource management actions.
