Abstract:
The Picus Sonic Tomograph is a noninvasive tool for assessing decay in trees. It works on the principle that sound waves passing through decay move more slowly than sound waves transversing solid wood. By sending sound waves from a number of points around a tree trunk to the same number of receiving points, the relative speed of the sound can be calculated, and a two-dimensional image of the cross-section of the tree, a tomogram, can be generated. Picus tomography and visual inspection were used to evaluate 27 cross-sections from 13 trees. The tomograms correlated closely with the visual asses

Abstract:
Tree mortality plays a vital role in the accuracy of growth and yield calculations. Economic loss caused by Heterobasidion sp. and Armillaria sp. is a common issue in forestry. Estonian forests, which are mostly managed, are susceptible to fungal infection due to freshly exposed wood surfaces, such as stumps and mechanical wounds. External signs of infection are often scarce and may lead to incorrect stand vitality valuation. Modern devices, such as the PiCUS 3 Sonic Tomograph, can be used for non-destructive decay assessment. We assessed decay in two intensively managed Norway spruce (Picea a

Abstract:
Using non-destructive techniques in investigating tree stem rots is a modern approach in arboriculture and urban forestry. We used PiCUS<sup>®</sup> 3 Sonic tomograph (SoT) and TreeTronic<sup>®</sup> electrical resistance tomograph (ERT) to inspect the health status of urban and park trees. The process of setting up the device and measuring is time demanding as it requires numerous delicate operations. The aim of the study was to evaluate the time needed for measurement and to propose an optimal workflow. The results of work sampling suggest that scanning of one average

The aim of the study was to examine the usefulness of The Picus 3 Sonic Tomograph to assess the health state of trees of monumental sizes, which are an important part of the cultural landscape. In the study there were selected tree species Tilia cordata, Gingko biloba and Ulmus glabra growing in the vicinity of Lublin in different habitat conditions. Changes in the internal structure of the tree trunks were shown on the colour tomograms. Two tested specimens of Tilia cordata located in Radawiec Duży were intended to be cut down due to the construction of the ring road of Lublin. This made it p

Abstract:
Tree health monitoring of risky trees is necessary, especially in areas with a high level of accessibility, such as in hotels and tourist areas. The increased accessibility of hotel visitors and the green space require increased awareness of the risk of falling trees. This research aimed to estimate the amount of internal decay and damage of living trees, with special attention to the large tree in the open space of R Hotel Rancamaya. Tree health monitoring was carried out using two approaches, namely visual observation Sonic Tomography method. The visual parameters were observed following the

Abstract. This study aimed to improve the usefulness of 3D scanning as an alternative to the biased measurement method for getting tree trunk geometry using a calliper in sonic tomography for tree health diagnosis. To this end, this study constructed geometry information using PiCUS Calliper and a 3D scanner on an old giant tree located in Buyeo-gun and compared the results with sonic measurements.Of the two instruments, the 3D scanner has the advantage of realizing the geometry of the object more closely than the calliper, which uses the principle of three-point surveying.

Abstract:
The incidence and severity of butt rot were assessed in 12 selected Norway spruce seed stands in the Beskidy Mountains, Poland. A semi-invasive technique of sonic tomography was used for the assessment of rot damage. Stands of different age classes (100–120, 130–150, 160–170 years old) and distinct regions of provenance (Istebna and Orawa) were investigated. Hierarchical analysis of variance was used to determine effects of stand age and stand provenance on butt rot occurrence at a stand level. High incidence of butt rot was noted in all of the studied seed stands (47% to 87%

Abstract:
In many spruce stands, trees are frequently attacked by the pathogen Heterobasidion parviporum, albeit without visible symptoms in the crown. In the present work, the results of the presence of stem rot, assessed by PICUS Sonic Tomography, and the fungal biota on trees and stumps in eight plots in the Puszcza Borecka Forest are described. The plots were located in stands on original forest soil (4) and on post-agricultural soil (4), where around a stump with H. parviporum symptoms (signs of internal rot and basidiocarps), 30 trees were selected and examined for internal rot.

The legacy seismic had an inherent seismic acquisition issue as it was a streamer acquisition acquired along the geologic structural strike direction. With the legacy seismic it was difficult to mature and explore the especially the deeper opportunities in the field and not allowing for full realization of the hydrocarbon potentials in the area.
