Cytisus scoparius (L.) is a common native species of the Chaîne des Puys, a mid-elevation volcanic mountain range of the French Massif Central. Widely used in the former traditional agricultural system, broom has now become an invasive species colonising open areas after grazing abandonment. This study quantifies variation in size as a function of age and local competition at both stand and ind...

Pterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. & Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter studies growth individual trees. In this sense, present study aimed morphometric relationships P. B. as resource describe features these species. Data...

The present study investigated double sampling with regression estimators as a quest for efficiency and effectiveness in forest inventory in Namibian woodlands. Auxiliary data used were obtained from Standard QuickBird satellite scenes (phase 1) for Hans Kanyinga Community Forest from October and November 2004 covering an area of 12,107 hectares, amplified with terrestric data (phase 2) of 2002...

Anecdotal evidence gathered from pruning crew observations indicates that there may be enhanced branch growth at the new crown base in young pruned coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) trees compared to unpruned trees. This has the potential to reduce the quality and value of the stem above the pruned portion of the bole. An analysis of the size of branches in the remainin...

The objective of this study is to develop new algorithms for automated urban forest inventory at the individual tree level using LiDAR point cloud data. LiDAR data contain three-dimensional structure information that can be used to estimate tree height, base height, crown depth, and crown diameter. This allows precision urban forest inventory down to individual trees. Unlike most of the publish...

AIM This was to investigate the dental characteristics (caries sensitivity and tooth crown size of permanent elements) in subjects affected by Turner Syndrome (TS). PATIENTS AND METHODS A group of 25 patients affected by TS, aged from 4 to 18 years, was selected and the data were compared to those of an age matched control healthy group. The caries index values in TS patients are higher in th...

In most cases forest practice in Austria use yield tables to predict the growth of their forests. Common yield tables show the increment of pure even-aged stands which are treated in a way the table developer recommends. The usage of these tables in stands which are either unevenaged, mixed or treated in another way, may lead to inaccurate predictions. To avoid these problems, forest growth mod...

We quantified structural attributes in three alluvial flat old-growth coast redwood stands. Tree size parameters and occurrences of distinctive features (e.g., burls, goose pens) were similar between stands. Occurrence of distinctive features was greater among larger trees. Tree sizefrequency distributions conformed to a reverse-J diameter distribution. The range of tree sizes was similar betwe...

The government of Mexico City carried out the introduction palm trees in 50s to increase visual appearance main avenues. As a result these exotic species, phytosanitary problems appeared. Currently there is scarce information on how evaluate health majestic monocots, this sense, it necessary implement assessment scales determine condition most frequently found species advance their care and man...
