DEVELOPING AN INDEX FOR FOREST PRODUCTIVITY MAPPING - A CASE STUDY FOR MARITIME PINE PRODUCTION REGULATION IN PORTUGAL

Revista Árvore, 2018
Productivity is very dependent on the environmental and biotic factors present at the site where the forest species of interest is present. Forest site productivity is usually assessed using empirical models applied to inventory data providing discrete ...

Developing soil quality indices for predicting site classes in Pinus patula stands of Sao Hill and Shume Forest Plantations, Tanzania

Sustainable Environment
Soil quality indices (SQIs) are comprehensive measures of soil function, integrating physical, chemical, and biological properties, which are used globally to predict suitable sites for agricultural and forest productivity. However, a lack of information

Applying total interpretive structural modeling to study factors affecting construction labour productivity

Construction Economics and Building, 2014
Construction sector has always been dependent on manpower. Most of the activities carried out on any construction site are labour intensive. Since productivity of any project depends directly on productivity of labour, it is a prime responsibility of the

Community level offset of rain use- and transpiration efficiency for a heavily grazed ecosystem in inner Mongolia grassland.

PLoS ONE, 2013
Water use efficiency (WUE) is a key indicator to assess ecosystem adaptation to water stress. Rain use efficiency (RUE) is usually used as a proxy for WUE due to lack of transpiration data.

Assessing site productivity based on national forest inventory data and its dependence on site conditions for spruce dominated forests in Germany

Forest Systems, 2019
Aim of study: (i) To estimate site productivity based on German national forest inventory (NFI) data using above-ground wood biomass increment (ΔB) of the stand and (ii) to develop a model that explains site productivity quantified by ΔB in dependence on

Evaluation of oriental beech (Fagus orientalis L.) site productivity using generalized additive model (Case study: Tarbiat Modares University Forest Research Station) [PDF]

مجله جنگل ایران, 2015
Site productivity is a key indicator of forest ecosystem; therefore it is an important criterion for forest manager for estimating the yield, annual exploitation and growth, and choosing the most suitable tree species for sites as well.
