Sinarundinaria alpina (Schumann) C.S. Chao & Renvoise, a tropical African montane bamboo, is heavily used by local communities for household items such as granaries, baskets, ropes and trays. This article presents the results of a study carried out on the abundance, distribution and utilisation of S. alpina in Bwindi and Mgahinga National Parks. Both in-forest and household surveys were used to...

It is well known that characteristics of individual trees, such as tree height, biomass and crown area, can be derived from airborne laser scanning (ALS) and that heights for individual trees can be obtained with an accuracy of 0.5 to 1.5 m. However, the ability to measure the growth of individual trees using ALS has not been documented. This paper reports multi-temporal laser surveys conducted...

This paper presents how log-linear models can be used for modelling and forecasting structural changes of Finnish non-industrial private forest ownership. Two crosssectional sets of data, which were collected in conjunction with two separate surveys by means of mail questionnaires in 1975 and 1990, were employed. A total of six nonindustrial private forest holding and ownership attributes are f...

We reviewed construct validity in perception-based methods assessing status and/or trend of forest condition as applied in 19 empirical studies that evaluated the conservation impact of popular participation in forest management. Perception-based methods focus on eliciting peoples’ assessment of the status and/or trend in forest condition or indicators of forest condition through interviews, su...

Forest types mapping is one of the most necessary elements in forest management and Silviculture treatments. Traditional methods such as field surveys are time-consuming and cost-intensive. Improving satellite data sources and classification methods offer new opportunities for obtaining more accurate forest biophysical maps. This research compares performance of three non-parametric and tree-ba...

A five-year drought in California led to a significant increase in tree mortality in the Sierra Nevada forests from 2012 to 2016. Landscape level monitoring of forest health and tree dieback is critical for vegetation and disaster management strategies. We examined the capability of multispectral imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) in detecting and explaining ...
