Stone Pine (Pinus Pinea L.) Detection from High-Resolution UAV Imagery Using Deep Learning Model

IEEE International Geoscience and Remote Sensing Symposium, 2022
The automatic detection and counting of trees are crucial for yield estimations, agricultural planning and forestry applications. Unmanned aerial vehicles (UAVs) and computer vision are increasingly used together for automatic image analysis since they ...

An assessment of conventional and drone-based measurements for tree attributes in timber volume estimation: A case study on stone pine plantation

Ecological Informatics, 2021
The use of unmanned aerial vehicles (UAVs) as a useful tool in forestry studies is increasing rapidly. The level of accuracy in UAV-supported measurement data has been increasing in the field of forestry.

Chloroplast microsatellites and mitochondrial nad1 intron 2 sequences indicate congruent phylogenetic relationships among Swiss stone pine (Pinus cembra), Siberian stone pine (Pinus sibirica), and Siberian dwarf pine (Pinus pumila) [PDF]

open access: possibleMolecular Ecology, 2001
AbstractWe studied the phylogenetic relationships among the three stone pine species, Pinus cembra, P. sibirica, and P. pumila, using chloroplast microsatellites and mitochondrial nad1 intron 2 sequences. The three chloroplast microsatellite loci combined into a total of 18 haplotypes. Fourteen haplotypes were detected in 15 populations of P.

Testing the Radial Increment and Climate–Growth Relationship Between Swiss Stone Pine European Provenances in the Romanian Carpathians

Forests
Swiss stone pine (Pinus cembra L.) may represent a vital species for afforestation at the upper altitudinal limits of forests due to its adaptability to challenging environmental conditions.

Stone Pine Pinus Pinea L.

2018
Stone pine (Pinus pinea L.) is a Mediterranean native conifer species. It is used for protection against soil erosion, ecosystem restoration and farmland afforestation. The most important commercial application is the production of timber and pine nuts.

Stone pine forests in Siberia

Journal of Forestry Research, 1997
Stone pine forests in Siberia are unique for their origin, area dynamics, comprehensive productivity, and biospherical role. They are mainly mature forests for the most regions. The regeneration has two main tasks: (1) to organize the rational and ecological felling for the Siberian stone pine trees, (2) to increase young growth.

Molecular and Quantitative Genetics of Stone Pine (Pinus pinea)

2019
The Mediterranean stone pine is currently on its way to domestication. Its genuine Mediterranean pine nuts are among the most expensive nuts in the world because they are mainly wild-collected from pine forests and woodlands. Despite the wide current distribution of stone pine over the whole Mediterranean biome, old-growth forests are scarce, often ...

Disentangling the effects of geographic peripherality and habitat suitability on neutral and adaptive genetic variation in Swiss stone pine

Molecular Ecology, 2020
It is generally accepted that the spatial distribution of neutral genetic diversity within a species’ native range mostly depends on effective population size, demographic history, and geographic position.
